If within one year two years after the date of Substantial Completion or such longer period of time as may be prescribed by Laws or Regulations or by the terms of any applicable special guarantee required by the Contract Documents or by any specific provision of the Contract Documents, any Work is found to be defective, CONTRACTOR shall promptly, without cost to OWNER and in accordance with OWNER's written instructions: (i) correct such defective Work, or, if it has been rejected by OWNER, remove it from the site and replace it with Work that is not defective, and (ii) satisfactorily correct or remove and replace any damage to other Work or the work of others resulting therefrom. If CONTRACTOR does not promptly comply with the terns of such instructions, or in an emergency where delay would cause serious risk of loss or damage, OWNER may have the defective Work corrected or the rejected Work removed and replaced, and all claims, costs, losses and damages caused by or resulting from such removal and replacement (including but not limited to all costs of repair or replacement of work of others) will be paid by CONTRACTOR. 13.12.2.In special circumstances where a particular item of equipment is placed in continuous service before Substantial Completion of all the Work, the correction period for that item may start to run from an earlier date if so provided in the Specifications or by Written Amendment. 13.12.3. Where defective Work (and damage to other E1CDC GENERAL CONDITIONS 1910-8 (1990 Edition) 28 w/ CITY OF FORT COLLINS MODIFICATIONS (REV 4/2000) Work resulting therefrom) has been corrected, removed or replaced under this paragraph 13.12, the correction period hereunder with respect to such Work will be extended for an additional period of one-year two years after such correction or removal and replacement has been satisfactorily completed. Acceptance of Defective Work: 13.13. If, instead of requiring correction or removal and replacement of defective Work, OWNER (and, prior to ENGINEER's recommendation of final payment, also ENGINEER) prefers to accept it, OWNER may do so. CONTRACTOR shall pay all claims, costs, losses and damages attributable to OWNER's evaluation of and determination to accept such defective Work (such costs to be approved by ENGINEER as to reasonableness). If any such acceptance occurs prior to ENGINEER's recommendation of final payment, a Change Order will be issued incorporating the necessary revisions in the Contract Documents with respect to the Work; and OWNER shall be entitled to an appropriate decrease in the Contract Price, and, if the parties are unable to agree as to the amount thereof, OWNER may make a claim therefor as provided in Article 11. If the acceptance occurs after such recommendation, an appropriate amount will be paid by CONTRACTOR to OWNER. OWNER May Correct Defective Work: 13.14. If CONTRACTOR fails within a reasonable time after written notice from ENGINEER to correct defective Work or to remove and replace rejected Work as required by ENGINEER in accordance with paragraph 13.11, or if CONTRACTOR fails to perform the Work in accordance with the Contract Documents, or if CONTRACTOR fails to comply with any other provision of the Contract Documents, OWNER may, after seven days' written notice to CONTRACTOR, correct and remedy any such deficiency. In exercising the rights and remedies under this paragraph OWNER shall proceed expeditiously. In connection with such corrective and remedial action, OWNER may exclude CONTRACTOR from all or part of the site, take possession of all or part of the Work, and suspend CONTRACTOR's services related thereto, take possession of CONTRACTOR's tools, appliances, construction equipment and machinery at the site and incorporate in the Work all materials and equipment stored at the site or for which OWNER has paid CONTRACTOR but which are stored elsewhere. CONTRACTOR shall allow OWNER, OWNER's representatives, agents and employees, OWNER's other contractors and ENGINEER and ENGINEER's Consultants access to the site to enable OWNER to exercise the rights and remedies under this paragraph. All claims, costs, losses and damages incurred or sustained by OWNER in exercising such rights and remedies will be charged against CONTRACTOR and a Change Order will be issued incorporating the necessary revisions in the Contract Documents with respect to the Work; and OWNER shall be entitled to an appropriate decrease in the Contract Price, and, if the parties are unable to agree as to the amount thereof, OWNER may make a claim therefor as provided in Article 11. Such claims, costs, losses and damages will include but not be limited to all costs of repair or replacement of work of others destroyed or damaged by correction, removal or replacement of CONTRACTOR's defective Work. CONTRACTOR shall not be allowed an extension of the Contract Times (or Milestones) because of any delay in performance of the Work attributable to the exercise by OWNER of OWNER's rights and remedies hereunder. ARTICLE 14—PAYMENTS TO CONTRACTOR AND COMPLETION Schedule of Values: 14.1. The schedule of values established as provided in paragraph 2.9 will serve as the basis for progress payments and will be incorporated into a form of Application for Payment acceptable to ENGINEER. Progress payments on account of Unit Price Work will be based on the number of units completed. Application for Progress Payment. 14.2. At least twenty days before the date established for each progress payment (but not more often than once a month), CONTRACTOR shall submit to ENGINEER for review an Application for Payment filled out and signed by CONTRACTOR covering the Work completed as of the date of the Application and accompanied by such supporting documentation as is required by the Contract Documents. If payment is requested on the basis of materials and equipment not incorporated in the Work but delivered and suitably stored at the site or at another location agreed to in writing, the Application for Payment shall also be accompanied by a bill of sale, invoice or other documentation warranting that OWNER has received the materials and equipment free and clear of all Liens and evidence that the materials and equipment are covered by appropriate property insurance and other arrangements to protect OWNER's interest therein, all of which will be satisfactory to OWNER. The amount of retainage with respect to progress payments will be as stipulated in the Agreement. Any funds that are withheld by the OWNER shall not be subject to substitution by the CONTRACTOR with securities or any arrangements involving an escrow or custodianship. By executing the application for payment form the CONTRACTOR expressly waives his right to the benefits of Colorado Revised Statutes, Section 24-91-101, et sea. COIVTRACTOR's Warranty of Title: 14.3. CONTRACTOR warrants and guarantees that title to all Work, materials and equipment covered by any Application for Payment, whether incorporated in the Project or not, will pass to OWNER no later than the time of payment free and clear of all Liens. Review of Applicationsfor Progress Payment. 14.4. ENGINEER will, within ten days after receipt of each Application for Payment, either indicate in writing a EJCDC GENERAL CONDITIONS 1910-8 (1990 Edition) w/ CITY OF FORT COLLINS MODIFICATIONS (REV 4/2000) recommendation of payment and present the Application to OWNER, or return the Application to CONTRACTOR indicating in writing ENGINEER's reasons for refusing to recommend payment. In the latter case, CONTRACTOR may make the necessary corrections and resubmit the Application. Ten days after presentation of the Application for Payment to OWNER with ENGINEER's recommendation, the amount recommended will (subject to the provisions of the last sentence of paragraph 14.7) become due and when due will be paid by OWNER to CONTRACTOR 14.5. ENGINEER's recommendation of any payment requested in an Application for Payment will constitute a representation by ENGINEER to OWNER, based on ENGINEER's on -site observations of the executed Work as an experienced and qualified design professional and on ENGINEER's review of the Application for Payment and the accompanying data and schedules, that to the best of ENGINEER's knowledge, information and belief 14.5.1. the Work has progressed to the point indicated, 14.5.2. the quality of the Work is generally in accordance with the Contract Documents (subject to an evaluation of the Work as a functioning whole prior to or upon Substantial Completion, to the results of any subsequent tests called for in the Contract Documents, to a final determination of quantities and classifications for Unit Price Work under paragraph 9.10, and to any other qualifications stated in the recommendation), and 14.5.3. the conditions precedent to CONTRACTOR's being entitled to such payment appear to have been fulfilled insofar as it is ENGINEER's responsibility to observe the Work. However, by recommending any such payment ENGINEER will not thereby be deemed to have represented that: (i) exhaustive or continuous on -site inspections have been made to check the quality or the quantity of the Work beyond the responsibilities specifically assigned to ENGINEER in the Contract Documents or (ii) that there may not be other matters or issues between the parties that might entitle CONTRACTOR to be paid additionally by OWNER or entitle OWNER to withhold payment to CONTRACTOR. 14.6. ENGINEER's recommendation of any payment, including final payment, shall not mean that ENGINEER is responsible for CONTRACTOR's means, methods, techniques, sequences or procedures of construction, or the safety precautions and programs incident thereto, or for any failure of CONTRACTOR to comply with Laws and Regulations applicable to the furnishing or performance of Work, or for any failure of CONTRACTOR to perform or furnish Work in accordance with the Contract Documents. 14.7. ENGINEER may refuse to recommend the whole or any part of any payment if, in ENGINEER's opinion, it would be incorrect to make the representations to 29 OWNER referred to in paragraph 14.5. ENGINEER may also refuse to recommend any such payment, or, because of subsequently discovered evidence or the results of subsequent inspections or tests, nullify any such payment previously recommended, to such extent as may be necessary in ENGINEER's opinion to protect OWNER from loss because: 14.7.1. the Work is defective, or completed Work has been damaged requiring correction or replacement, 14.7.2. the Contract Price has been reduced by Written Amendment or Change Order, 14.7.3. OWNER has been required to correct defective Work or complete Work in accordance with paragraph 13.14,or 14.7.4. ENGINEER has actual knowledge of the occurrence of any of the events enumerated in paragraphs 15.2.1 through 15.2.4 inclusive. OWNER may refuse to make payment of the full amount recommended by ENGINEER because: 14.7.5. claims have been made against OWNER on account of CONTRACTOR's performance or furnishing of the Work, 14.7.6. Liens have been filed in connection with the Work, except where CONTRACTOR has delivered a specific Bond satisfactory to OWNER to secure the satisfaction and discharge of such Liens, 14.7.7. there are other items entitling OWNER to a set- off against the amount recommended, or 14.7.8. OWNER has actual knowledge of the occurrence of any of the events enumerated in paragraphs 14.7.1 through 14.7.3 or paragraphs 15.2.1 through 15.2.4 inclusive; but OWNER must give CONTRACTOR immediate written notice (with a copy to ENGINEER) stating the reasons for such action and promptly pay CONTRACTOR the amount so withheld, or any adjustment thereto agreed to by OWNER and CONTRACTOR, when CONTRACTOR corrects to OWNER's satisfaction the reasons for such action. Substantial Completion: 14.8. When CONTRACTOR considers the entire Work ready for its intended use CONTRACTOR shall notify OWNER and ENGINEER in writing that the entire Work is substantially complete (except for items specifically listed by CONTRACTOR as incomplete) and request that ENGINEER issue a certificate of Substantial Completion. Within a reasonable time thereafter, OWNER, CONTRACTOR and ENGINEER shall make an inspection of the Work to determine the status of completion. If ENGINEER does not consider the Work substantially complete, ENGINEER will notify CONTRACTOR in writing giving the reasons therefor. If ENGINEER 30 EICDC GENERAL CONDITIONS 1910-8 (1990 Edition) w/ CITY OF FORT COLLINS MODIFICATIONS (REV 4/2000) considers the Work substantially complete, ENGINEER will prepare and deliver to OWNER a tentative certificate of Substantial Completion which shall fix the date of Substantial Completion. There shall be attached to the certificate a tentative list of items to be completed or corrected before final payment OWNER shall have seven days after receipt of the tentative certificate during which to make written objection to ENGINEER as to any provisions of the certificate or attached list. If, after considering such objections, ENGINEER concludes that the Work is not substantially complete, ENGINEER will within fourteen days after submission of the tentative certificate to OWNER notify CONTRACTOR in writing, stating the reasons therefor. If, after consideration of OWNER's objections, ENGINEER considers the Work substantially complete, ENGINEER will within said fourteen days execute and deliver to OWNER and CONTRACTOR a definitive certificate of Substantial Completion (with a revised tentative list of items to be completed or corrected) reflecting such changes from the tentative certificate as ENGINEER believes justified after consideration of any objections from OWNER. At the time of delivery of the tentative certificate of Substantial Completion ENGINEER will deliver to OWNER and CONTRACTOR a written recommendation as to division of responsibilities pending final payment between OWNER and CONTRACTOR with respect to security, operation, safety, maintenance, heat, utilities, insurance and warranties and guarantees. Unless OWNER and CONTRACTOR agree otherwise in writing and so inform ENGINEER in writing prior to ENGINEER's issuing the definitive certificate of Substantial Completion, ENGINEER's aforesaid recommendation will be binding on OWNER and CONTRACTOR until final payment 14.9. OWNER shall have the right to exclude CONTRACTOR from the Work after the date of Substantial Completion, but OWNER shall allow CONTRACTOR reasonable access to complete or correct items on the tentative list. Partial Utilization: 14.10. Use by OWNER at OWNER's option of any substantially completed part of the Work, which: (i) has specifically been identified in the Contract Documents, or (ii) OWNER, ENGINEER and CONTRACTOR agree constitutes a separately functioning and usable part of the Work that can be used by OWNER for its intended purpose without significant interference with, CONTRACTOR's performance of the remainder of the Work, may be accomplished prior to Substantial Completion of all the Work subject to the following: 14.10.1.OWNER at any time may request CONTRACTOR in writing to permit OWNER to use any such part of the Work which OWNER believes to be ready for its intended use and substantially complete. If CONTRACTOR agrees that such part of the Work is substantially complete, CONTRACTOR will certify to OWNER and ENGINEER that such part of the Work is substantially complete and request ENGINEER to issue a certificate of Substantial Completion for that part of the Work. M CONTRACTOR at any time may notify OWNER and ENGINEER in writing that CONTRACTOR considers any such part of the Work ready for its intended use and substantially complete and request ENGINEER to issue a certificate of Substantial Completion for that part of the Work. Within a reasonable time after either such request, OWNER, CONTRACTOR and ENGINEER shall make an inspection of that part of the Work to determine its status of completion. If ENGINEER does not consider that part of the Work to be substantially complete, ENGINEER will notify OWNER and CONTRACTOR in writing giving the reasons therefor. If ENGINEER considers that part of the Work to be substantially complete, the provisions of paragraphs 14.8 and 14.9 will apply with respect to certification of Substantial Completion of that part of the Work and the division of responsibility in respect thereof and access thereto. 14.10.2. No occupancy or separate operation of part of the Work will be accomplished prior to compliance with the requirements of paragraph 5.15 in respect of property insurance. Final Inspection: 14.11. Upon written notice from CONTRACTOR that the entire Work or an agreed portion thereof is complete, ENGINEER will make a final inspection with OWNER and CONTRACTOR and will notify CONTRACTOR in writing of all particulars in which this inspection reveals that the Work is incomplete or defective. CONTRACTOR shall immediately take such measures as are necessary to complete such work or remedy such deficiencies. Final Application for Payment. 14.12. After CONTRACTOR has completed all such corrections to the satisfaction of ENGINEER and delivered in accordance with the Contract Documents all maintenance and operating instructions, schedules, guarantees, Bonds, certificates or other evidence of insurance required by paragraph 5.4, certificates of inspection, marked -up record documents (as provided in paragraph 6.19) and other documents, CONTRACTOR may make application for final payment following the procedure for progress payments. The final Application for Payment shall be accompanied (except as previously delivered) by: (i) all documentation called for in the Contract Documents, including but not limited to the evidence of insurance required by subparagraph 5.4.13, (ii) consent of the surety, if any, to final payment, and (iii) complete and legally effective releases or waivers (satisfactory to OWNER) of all Liens arising out of or filed in connection with the Work. In lieu of such releases or waivers of Liens and as approved by OWNER, CONTRACTOR may furnish receipts or releases in full and affidavit of CONTRACTOR that: (i) the releases and receipts include all labor, services, material and equipment for which a Lien could be filed, and (ii) all payrolls, material and equipment bills, and other indebtedness connected with the Work for which OWNER or OWNERSs property might in any way be responsible have been paid or otherwise satisfied. If any Subcontractor or Supplier fails EJCDC GENERAL CONDITIONS 1910-8 (1990 Edition) w/ CITY OF FORT COLLINS MODIFICATIONS (REV 4/2000) to furnish such a release or receipt in full, CONTRACTOR may furnish a Bond or other collateral satisfactory to OWNER to indemnify OWNER against any Lien. Releases or waivers of liens and the consent of the surety to finalize payment are to be submitted on forms conforming to the format of the OWNER'S standard forms bound in the Proiect manual. Final Payment and Acceptance: 14.13. If, on the basis of ENGINEER's observation of the Work during construction and final inspection, and ENGINEER's review of the final Application for Payment and accompanying documentation as required by the Contract Documents, ENGINEER is satisfied that the Work has been completed and CONTRACTOR's other obligations under the Contract Documents have been fulfilled, ENGINEER will, within ten days after receipt of the final Application for Payment, indicate in writing ENGINEER's recommendation of payment and present the Application to OWNER for payment. At the same time ENGINEER will also give written notice to OWNER and CONTRACTOR that the Work is acceptable subject to the provisions of paragraph 14.15. Otherwise, ENGINEER will return the Application to CONTRACTOR, indicating in writing the reasons for refusing to recommend final payment, in which case CONTRACTOR shall make the necessary corrections and resubmit the Application. Thirty days after presentation to OWNER of the Application and accompanying documentation, in appropriate form and substance and with ENGINEER's recommendation and notice of acceptability, the amount recommended by ENGINEER will become due and will be paid by OWNER to CONTRACTOR subiect to paragraph 17.6.2 of these General Conditions. 14.14. If, through no fault of CONTRACTOR, final completion of the Work is significantly delayed and if ENGINEER so confirms, OWNER shall, upon receipt of CONTRACTOR's final Application for Payment and recommendation of ENGINEER, and without terminating the Agreement, make payment of the balance due for that portion of the Work fully completed and accepted. If the remaining balance to be held by OWNER for Work not fully completed or connected is less than the retainage stipulated in the Agreement, and if Bonds have been furnished as required in paragraph 5.1, the written consent of the surety to the payment of the balance due for that portion of the Work fully completed and accepted shall be submitted by CONTRACTOR to ENGINEER with the Application for such payment. Such payment shall be made under the terms and conditions governing final payment, except that it shall not constitute a waiver of claims, Waiver of Claims: 14.15. The making and acceptance of final payment will constitute: 14.15.1. a waiver of all claims by OWNER against CONTRACTOR, except claims arising from unsettled Liens, from defective Work appearing after 31 Mathews Street, Fort Collins. Prospective Bidders are invited to present their questions relative to this Bid proposal at this meeting. Bids will be received as set forth in the Bidding Documents. The Work is expected to be commenced within the time as required by Section 2.3 of General Conditions. Substantial Completion of the Work is required as specified in the Agreement. The successful Bidder will be required to furnish a Performance Bond and a Payment Bond guaranteeing faithful performance and the payment of all bills and obligations arising from the performance of the Contract. No Bid may be withdrawn within a period of forty-five (45) days after the date fixed for opening Bids. The OWNER reserves the right to reject any and all Bids, and to waive any informalities and irregularities therein. Bid security in the amount of not less than 5% of the total Bid must accompany each Bid in the form specified in the Instructions to Bidders.

At any time and without cause, OWNER may suspend the Work or any portion thereof for a period of not more than ninety days by notice in writing to CONTRACTOR and ENGINEER which will fix the date on which Work will be resumed. CONTRACTOR shall resume the Work on the date so fixed. CONTRACTOR shall be allowed an adjustment in the Contract Price or an extension of the Contract Times, or both, directly attributable to any such suspension if CONTRACTOR makes an approved claim therefor as provided in Articles 11 and 12. OWNER May Terminate: 15.2. Upon the occurrence of any one or more of the following events: 15.2.1. if CONTRACTOR persistently fails to perform the Work in accordance with the Contract Documents (including, but not limited to, failure to supply sufficient skilled workers or suitable materials or equipment or failure to adhere to the progress schedule established under paragraph 2.9 as adjusted from time to time pursuant to paragraph 6.6); 15.2.2. if CONTRACTOR disregards Laws or Regulations of any public body having jurisdiction; 15.2.3. if CONTRACTOR disregards the authority of ENGINEER; or 15.2.4. if CONTRACTOR otherwise violates in any substantial way any provisions of the Contract Documents; OWNER may, after giving CONTRACTOR (and the surety, if any) seven days' written notice and to the extent permitted by Laws and Regulations, terminate the services of CONTRACTOR, exclude CONTRACTOR from the site and take possession of the Work and of all CONTRACTOR's tools, appliances, construction equipment and machinery at the site and use the same to the full extent they could be used by CONTRACTOR (without liability to CONTRACTOR for trespass or conversion), incorporate in the Work all materials and equipment stored at the site or for which OWNER has paid EJCDC GENERAL CONDITIONS 1910-8 (1990 Edition) 32 w/ CITY OF FORT COLLINS MODIFICATIONS (REV 4/2000) CONTRACTOR but which are stored elsewhere, and finish the Work as OWNER may deem expedient. In such case CONTRACTOR shall not be entitled to receive any further payment until the Work is finished If the unpaid balance of the Contract Price exceeds all claims, costs, losses and damages sustained by OWNER arising out of or resulting from completing the Work such excess will be paid to CONTRACTOR. If such claims, costs, losses and damages exceed such unpaid balance, CONTRACTOR shall pay the difference to OWNER. Such claims, costs, losses and damages incurred by OWNER will be reviewed by ENGINEER as to their reasonableness and when so approved by ENGINEER incorporated in a Change Order, provided that when exercising any rights or remedies under this paragraph OWNER shall not be required to obtain the lowest price for the Work performed. 15.3. Where CONTRACTOR's services have been so terminated by OWNER, the termination will not affect any rights or remedies of OWNER against CONTRACTOR then existing or which may thereafter accrue. Any retention or payment of moneys due CONTRACTOR by OWNER will not release CONTRACTOR from liability. 15.4. Upon seven days' written notice to CONTRACTOR and ENGINEER, OWNER may, without cause and without prejudice to any other right or remedy of OWNER, elect to terminate the Agreement. In such case, CONTRACTOR shall be paid (without duplication of any items): 1SA L for completed and acceptable Work executed in accordance with the Contract Documents prior to the effective date of termination, including fair and reasonable sums for overhead and profit on such Work; 15.4.2. for expenses sustained prior to the effective date of termination in performing services and furnishing labor, materials or equipment as required by the Contract Documents in connection with uncompleted Work, plus fair and reasonable sums for overhead and profit on such expenses; 15.4.3. for all claims, costs, losses and damages incurred in settlement of terminated contracts with Subcontractors, Suppliers and others; and 15.4.4. for reasonable expenses directly attributable to termination. CONTRACTOR shall not be paid on account of loss of anticipated profits or revenue or other economic loss arising out of or resulting from such termination. CONTRACTOR May Stop Work or Terminate: 15.5. If, through no act or fault of CONTRACTOR, the Work is suspended for a period of more than ninety days by OWNER or under an order of court or other public authority, or ENGINEER fails to act on any Application for Payment within thirty days after it is submitted or OWNER fails for thirty days to pay CONTRACTOR any sum finally determined to be due, then CONTRACTOR may, upon seven days' written notice to OWNER and ENGINEER, and provided OWNER or ENGINEER do not remedy such suspension or failure within that time, terminate the Agreement and recover from OWNER payment on the same terms as provided in paragraph 15.4. In lieu of terminating the Agreement and without prejudice to any other right or remedy, if ENGINEER has failed to act on an Application for Payment within thirty days after it is submitted, or OWNER has failed for thirty days to pay CONTRACTOR any sum finally determined to be due, CONTRACTOR may upon seven days' written notice to OWNER and ENGINEER stop the Work until payment of all such amounts due CONTRACTOR, including interest thereon. The provisions of this paragraph 15.5 are not intended to preclude CONTRACTOR from making claim under Articles 11 and 12 for an increase in Contract Price or Contract Times or otherwise for expenses or damage directly attributable to CONTRACTOR's stopping Work as permitted by this paragraph. ARTICLE 16—DISPUTE RESOLUTION If and to the extent that OWNER and CONTRACTOR have agreed on the method and procedure for resolving disputes between them that may arise under this Agreement, such dispute resolution method and procedure, if any, shall be as set forth in Exhibit GC -A, "Dispute Resolution Agreement", to be attached hereto and made a part hereof. If no such agreement on the method and procedure for resolving such disputes has been reached, and subject to the provisions of paragraphs 9.10, 9.11 and 9.12, OWNER and CONTRACTOR may exercise such rights or remedies as either may otherwise have under the Contract Documents or by Laws or Regulations in respect of any dispute. ARTICLE 17—MISCELLANEOUS Giving Notice. 17.1. Whenever any provision of the Contract Documents requires the giving of written notice, it will be deemed to have been validly given if delivered in person to the individual or to a member of the firm, or to an officer of the corporation for whom it is intended, or if delivered at or sent by registered or certified mail, postage prepaid, to the last business address known to the giver of the notice. 17.2. Computation of Time: 17.2.1. When any period of time is referred to in the Contract Documents by days, it will be computed to exclude the first and include the last day of such period.

EICDC GENERAL CONDITIONS 1910-8(1990 Edition) 35 w/ CITY OF FORT COLLINS MODIFICATIONS (REV 4/2000) 36 EJCDC GENERAL CONDITIONS 1910-8 (1990 Edition) w/CITY OF FORT COLLINS MODIFICATIONS (REV 4/2000) EXHIBIT GC -A to General Conditions of the Construction Contract Between OWNER and CONTRACTOR DISPUTE RESOLUTION AGREEMENT OWNER and CONTRACTOR hereby agree that Article 16 of the General Conditions of the Construction Contract between OWNER and CONTRACTOR is amended to include the following agreement of the parties: 16.1. All claims, disputes and other matters in question between OWNER and CONTRACTOR arising out of or relating to the Contract Documents or the breach thereof (except for claims which have been waived by the making or acceptance of final payment as provided by paragraph 14.15) will be decided by arbitration in accordance with the Construction Industry Arbitration Rules of the American Arbitration Association then obtaining, subject to the limitations of the Article 16. This agreement so to arbitrate and any other agreement or consent to arbitrate entered into in accordance herewith as provided in this Article 16 will be specifically enforceable under the prevailing law of any court having jurisdiction. 16.2. No demand for arbitration of any claim, dispute or other matter that is required to be referred to ENGINEER initially for decision in accordance with paragraph 9.11 will be made until the earlier of (a) the date on which ENGINEER has rendered a written decision or (b) the thirty-first day after the parties have presented their evidence to ENGINEER if a written decision has not been rendered by ENGINEER before that date. No demand for arbitration of any such claim, dispute or other matter will be made later than thirty days after the date on which ENGINEER has rendered a written decision in respect thereof in accordance with paragraph 9.11; and the failure to demand arbitration within said thirty days' period will result in ENGINEER's decision being final and binding upon OWNER and CONTRACTOR. If ENGINEER renders a decision after arbitration proceedings have been initiated, such decision may be entered as evidence but will not supersede the arbitration proceedings, except where the decision is acceptable to the parties concerned. No demand for arbitration of any written decision of ENGINEER rendered in accordance with paragraph 9.10 will be made later than ten days after the party making such demand has delivered written notice of intention to appeal as provided in paragraph 9.10. 16.3. Notice of the demand for arbitration will be filed in writing with the other party to the Agreement and with the American Arbitration Association, and a copy will be sent to ENGINEER for information. The demand for arbitration will be made within the thirty -day or ten-day period specified in paragraph 16.2 as applicable, and in all other cases within a reasonable time after the claim, dispute or other matter in question has arisen, and in no event shall any such demand be made after the date when institution of legal or equitable proceedings based on such claim, dispute or other matter in question would be barred by the applicable statute of limitations. EJCDC GENERAL. CONDITIONS 1910-8 (1990 Edition) w/ CITY OF FORT COLLINS MODIFICATIONS (REV 9/99) 16.4. Except as provided in paragraph 16.5 below, no arbitration arising out of or relating to the Contract Documents shall include by consolidation, joinder or in any other manner any other person or entity (including ENGINEER, ENGINEER's Consultant and the officers, directors, agents, employees or consultants of any of them) who is not a party to this contract unless: 16.4.1. the inclusion of such other person or entity is necessary if complete relief is to be afforded among those who are already parties to the arbitration, and 16.4.2. such other person or entity is substantially involved in a question of law or fact which is common to those who are already parties to the arbitration and which will arise in such proceedings, and 16.4.3. the written consent of the other person or entity sought to be included and of OWNER and CONTRACTOR has been obtained for such inclusion, which consent shall make specific reference to this paragraph; but no such consent shall constitute consent to arbitration of any dispute not specifically described in such consent or to arbitration with any party not specifically identified in such consent. 16.5.

Introduction 1.1 Research Background/participants Research Background The Fort Collins Museum (Museum) acquired the Franz -Smith Cabin from the Larimer County Historic Alliance in June 2000 and relocated It to the courtyard outside the Museum's building in Fort Collins, CO. The cabin, originally located in southwest Fort Collins, had been located on county land north of Fort Collins near Livermore for more than ten years. During that time the roof had been removed, and most of the windows had been removed or were broken, leaving it open to the elements. Much of the funding for the relocation by the Fort Collins Museum was provided for by the Don and May Wilkins Charitable Trust, with the balance being provided by the City of Fort Collins, the Downtown Development Authority, community donations and in -kind support The cost for moving the cabin, providing steel reinforcing, a new concrete pad, and a fence around the structure has been estimated at $35,000.00. The Museum's decision to relocate the cabin in order to save it was based on a number of reasons. First, Fort Collins City officials and Fort Collins Museum staff saw an opportunity to incorporate the Franz Smith cabin into plans for the Museum's expansion and revitalization. Second, the fact that it had already been moved from it's original location provided justification for another relocation with the Museum noting that they, as preservationists, "... refrain from moving things from their original relocation whenever we can." Third, the cabin, representing the agricultural history of the community, fit a gap in the Museum's historic cabin courtyard Interpretive program. In developing a Rlan for the restoration of the cabin, the Museum determined they needed a thorough assessment of the cabin's existing conditions and recommendations for repair and restoration. The Museum applied for, and received, a State Historical Fund Historic Structure Assessment Grant for the development of this report in the Summer of 2001. Director of Collections, Cheryl Donaldson, sought out the services of Ron Anthony, wood scientist, and Colorado State university's Architectural Preservation Institute to study the building and write the report. A key concern for the Franz -Smith cabin is the condition of the wood. There is evidence of moisture damage resulting in decayed wood throughout the structure. A detailed investigation of the wood members was conducted during August 2001. The purpose was to identify wood species used, assess the structural integrity of the logs and other wood members, determine the sources of moisture intrusion causing the deterioration and identify construction details which may aid in establishing original fabric and subsequent repairs. 1. Species Identification: The cabin makes use of logs for the exterior walls and dimension lumber for joists and boards for flooring. By determining the wood species of the logs, joists, boards and trim it may be possible to determine which materials are of local wood species and which may have been constructed of non - local species. For example, logs of Ponderosa pine would likely be of local origin while window trim identified as white pine would likely have been brought in to the area or represent replacement material. Wood species were identified by removing several small samples throughout the cabin from which the species or species group were identified by microscopic examination. I 2. Decay Quantification: The inspection of the wood members consisted of a combination of visual observations,_ moisture measurements and resistance drilling to determine loss of material due to wood decay. Resistance drilling is a quasi- " nondestructive technique for determining the relative density of wood. It is best suited for detemining Internal problems in timber which do not show obvious signs of deterioration, such as surface decay. Any internal void or early stage of decay at the location drilled can be detected by determining the relative density of the wood. The relative density is printed on a strip of paper as a small diameter needle penetrated the wood, as seen below for (a) a solid section and (b) a void. The technique is very reliable for quantifying the extent of voids when used in combination with other techniques fo rapidly locate areas of probable deterioration. . . . . . ra' @'. Figure 1. Results from resistance drilling showing (a) solid wood and _ (b) wood with internal decay. ti Resistance drilling was conducted on the exterior logs to determine the extent of deterioration and repair needs. Floor joists and roof Umbers were probed with an awl and moisture. measurements taken to locate areas with deterioration. 3. Moisture Determination: The effect of prolonged exposure to moisture is an — undesirable condition and results in long-term maintenance issues for wood in a structure. Excessive shrinkage or swelling, checking, loose connections and decay are typical problems. Moisture content measurements identify wood with favorable moisture levels for + the growth of wood -decay fungi. Generally. If moisture content is less than 20 percent wood -decay fungi are unable to grow. While fungi may be present at lower moisture contents they are unable to continue to deteriorate the wood without sufficient moisture. Moisture contents from 20 - 30 percent indicate areas of concern where sufficient moisture Is present for fungi to grow but generally not quite high enough to indicate advanced decay. A moisture content above 30 percent is often an indication of active decay with internal voids and / or surface deterioration. Moisture measurements were taken on dimension lumber and boards using a — capacitance -type meter, which provides moisture information to a depth of approximately 3/4 of an inch. Moisture measurements on the logs were taken with a resistance -type meter so that the internal moisture content of the wood can be determined. This information is useful, along with visual observations and 2 — M 1 r resistance drilling data, to establish patterns of moisture intrusion and deterioration and, therefore, determine priorities for repair. During the wood assessment of the cabin, observations on use of materials were made to aid in historic interpretation of the construction of the cabin. Observations included saw marks on dimension lumber and boards, notches on exterior log walls, types of nails and milling patterns on wood. Samples were also taken such as daubing, paint, and wallpaper for analysis at the Architectural Preservation Institute lab. Such information may make it possible to distinguish original fabric from material added at a later date, including replacement material. Participants Property Owner.

A 4 I 1.2 Building Location/Site Plan or Vicinity Map The Franz -Smith cabin is located in the courtyard of the Fort Collins Museum at 200 Mathews Street, Fort Collins, CO. The building was originally located adjacent to Shields Street near Harmony Road in Fort Collins. It was moved to county land near Livermore, CO in 1988 then to the Fort Collins Museum in June 2000. Map of northern Colorado Cabin's original location In Fnrt rnllins Cabin's current location at F. C. Museum 5 e 2. History and Use 2.1 Architectural Significance and Construction History The Franz -Smith Cabin was built c. 1882 in Fort Collins by German immigrant Henry Franz whose family farmed alfalfa as well as participated in the sugar beet and Iamb Industries. The cabin was rented to the Smith family for a period of time and then purchasgd by them in 1936. The cabin continued to serve as a residence until 1987. r -^ The Franz -Smith cabin resembles a Continental Plan which is defined by NPS Preservation Brief 26 as, '... a single -pen of three rooms organized around a central hearth.' The Franz -Smith cabin, however, has only two rooms separated by a central , staircase. The east room has two entrances, one on the long end (south) and one on the gable and (east). The location of the door at the gable end is typical of what is known as the &Rodry Mountain' cabin form. This We evolved, In the West in the mid-19th century (NPS, Preservation Brief 26). The cabin has four windows on the first story placed symmetrically, with two on each north and south side, and a window in each gable. The cabin Is an example of the use of hand-hewn square and round logs, with wood chinking and a mortar -like daubing. The second story attic room is believed to have been -' added in 1909 and has a half wall upon which a gabled roof was placed. The roof of the building was removed when the cabin was transported to Uvemrore, CO in 1988. The gable ends remain intact, but are not attached to the building, and the rafters may be located within the cabin's first floor east room. When restoration is completed, the period of interpretation will be the 1920's and the restored version will include a reconstruction of the roof system. See Fig. 1-Cabin at original location and Fig. 2-Cabin at Uvennore location. 2.2 Proposed Program The Fort Collins Museum plans to use the Franz -Smith cabin as part of its interpretive program involving three (3) other relocated historic cabins. The Franz -Smith cabin is unique to the Museum's collection of historic cabins as it represents the agricultural history of the area rather than the frontier history represented by the other cabins. As with the other cabins, the Franz -Smith cabin will be used for educational programming, and will be accessible to the public, Including individuals and groups, wishing to learn about the history of the Fort Collins area. The Museum also wishes to use the cabin to provide interpretative information on cabin construction, historic preservation treatments, and material deterioration mechanisms. 2.3 Existing Sketch Plan See site and floor plans in Section 7.0. C 3.0 Structure Condition Assessment 3.1 Site • Associated Landscape Features: The cabin is not currently located In its historic setting. The cabin was relocated from It's original site near Shields Street and Harmony Road, Fort Collins, CO to land owned by Ladmer County near Livermore, CO In 1988. It was then moved in June 2000 to its current location within the Fort Collins Museum courtyard. The courtyard contains four (4) other structures, the historic Auntle Stone cabin, Box Elder School cabin, and Janis cabin, and a non -historic workshop. Landscaping within the courtyard consists of grass, trees, paved walking paths, potted planters, and a historic stone well. The entire area was recently enclosed within a wrought - iron fence, with the Franz -Smith cabin -located in the southwest comer of the courtyard. See Fig. 3-View of courtyard with Franz-Smlth cabin in background and site plan In section 7.0. • Parking: Parking Is provided on adjacent streets. • Archaeology: There is no archeology is associated with this project as the cabin is not in Its original location. 3.2 Foundations • Perimeter Foundation Drainage Existing Conditions: Poor There has been no formal grading of the site to provide drainage away from the foundation slab. Treatment Recommendation: Slab edges should be ground to allow for water to drain away from building and soil should also be graded for drainage. Cost of Repairs Grading Slab grinding • Foundation System Existing Conditions: Poor Originally the cabin may have sat on a shallow stone foundation or have had the sill logs In direct contact with the soil. This is difficult to determine based on the available black and white photos (o. 1988). Currently the structure is raised on steel girders above a 160 deep mete slab. Treatment Recommendation: The cabin could be placed upon the existing slab. However, this could lead to accelerated deterioration of the sill logs as It increases the possibility of the logs being exposed to high moisture levels. Placing preservative treated lumber between the slab and the sill logs would deter possible future deterioration of the sill logs. If desired, stones could then be applied as a facing to simulate a stone foundation, which would be consistent with buildings of the cabin's era. The pressure -treated lumber should be 2x12 member(s). Metal flashing should be placed between the treated lumber and the sill logs to stop moisture wicked up by the lumber from coming in contact with the sill logs. There should also be ventilation, such as screen covered notches or holes in the lumber to allow any moisture which does get underneath the structure to dissipate easily. White this is only one possible solution, final design and detailing will require the input of a structural engineer, and appropriate reviewing agencies. Cost of Repairs: Pressure -treated lumber Stone facing Flashing • Backfill: Any necessary could be provided as part of the site grading. 3.3 Building Structural System • General Structural System Description Existing Conditions: Poor --i Fair a Good The cabin is a load -bearing log structure with hand-hewn (squared) logs making up the first floor walls, rounded, smaller logs creating a 1/2 story wail above, and a i dimension lumber, truss roofing system. The first floor joists consist of 2x6's spaced 240 apart, currently supported by the steel frame system used to move the structure. ^ T The second story floor joists consist of 2x6's supported at the ends by the log walls with the joist ends exposed through the exterior walls. The square hewn logs are original to the structure, with the rounded logs having been added in 1909 to form the 1/2 wall for the second story. The round logs have vertical wooden pegs joining them together for added structural stability. The first story flooring Is mainly being supported at this time by the steel frame system put in place to provide support for the structure during relocation. There is a central stairwell incorporating two closets providing access to the second story. A number of existing logs are either deteriorated due to fungal decay, or have 'shifted' causing 'bowing' of certain walls. It can be assumed that mucb of the fungal activity was caused by the structure being open to the elements (10. moisture) and unoccupied at the Livermore, CO location for more than ten years. Shifting of the logs and wall planes is most likely caused by deterioration of the logs, twice moving the structure, and lack of a roof truss system. Conditions drawings in section 6.0 indicate the location of fungal decay, and other conditions. • First Floor Structural System Existing Conditions: Poor The first floor is supported by wood joists spaced approximately 24' on ,center, although the spacing is not uniform. The joists span approximately 16' across the cabin with no intermediate supports and are, generally, in poor condition. Several joists are broken at the west.side of the cabin (Fig. 4). Others are decayed and warped. The joists are of circular sawn Douglas -fir with approximate dimensions of 1 7/6' by 5 3/40. The joists support a wood subfloor consisting of.10 thick boards. Prior to allowing public access to the first floor, an engineering assessment should be conducted to determine the amount of load that the first floor can support The wearing surface of the floor in the east room is 314" thick tongue -and -groove flooring, 34 wide (Fig. 5). Flooring (which may have been subfloodng) in the west room varies in width. Much of the flooring was inaccessible due to storage of lumber 7 W from the cabin on the first, but what was visible showed signs of weathering and minor splitting due to exposure to the elements over time. Moisture content readings on the wood joists and flooring were less than 20 percent. A variety of nails are visible securing the structural framing and millwork, including steel cut nails and common wire nails. The cut nails are probably original fabric Treatment Recommendation: Although a structural engineering assessment is necessary to determine the adequacy of the existing first floor system, for the purposes of this assessment it will be assumed that the majority of (possibly all) the floor joists require replacement. This can be accomplished by sistering new members to existing or replacing the existing joists. Cost of Repairs: Remove flooring Notch and install pressure -treated joists Reinstall floor (replacing decayed as needed) Remove and reinstall Interior walls and fixtures (Ind. stairs) Second Floor Structural System Existing Conditions: Poor The second floor is supported by wood joists spaced approximately 24" on center. The joists span approximately 15 across the cabin with no Intermediate supports. The joists are of circular sawn Douglas -fir with approximate dimensions of 1 7/8" by 5 3/4" (Fig. 6). The joists have considerable sag, most likely due to the long span and shallow depth of the beams. Prior to allowing public access to the second floor, an engineering assessment should be conducted to determine the amount of bad that the second floor can support The wearing surface consists of nominal 1" thick lumber laid perpendicular to the joists. There is currently no subfloor. The floorboards exhibit considerable warp due to prolonged exposure to the elements and will need replacement should the second floor be made accessible to the public. Treatment Recommendation: Although a thorough structural engineering assessment is necessary to determine the appropriate design for repair/replacement of the existing second floor system, for the purposes of this assessment it will be assumed that the all the floor joists and subfloor require replacement. Cost of Repairs: Replace existing I flooring and joists Replace joists with similar douglas fir joists Replace subfloor with similar Roof Framing System Existing Conditions: None The structure currently has no roof Installed. The two gable ends exist but are not attached to the cabin (Fig. 7). The gable ends are constructed of 2x4dimension lumber framing with 1" thick boards of various widths (9-128) for cladding. The lumber Is poor quality with numerous large knots. There is termite damage at one end of the one of the gable frames (Fig. 8). Most of the boards are it fair condition, showing signs of weathering, minor surface deterioration and warping. 22.0 PURCHASING RESTRICTIONS.

END OF SECTION 7/96 Section 00100 Page 8 C. 1988 Photos taken prior to the structure's first relocation (Fig. 9) show that the roof framing system consisted of dimensioh lumber 2x4 rafters with collar beams. The _ lumber stacked within the cabin Interior may be the historic rafters and collar beams. The roof pitch is approximately 6:12. Treatment Recommendation: If the stacked lumber In the cabin Is determined by the designer and/or contractor to Indeed be the original rafter and collar beam material, and is in sound condition, that material could be reused in the reconstruction of the roof framing, system per the available photo documentation. If new material is needed, material of similar species and dimensions should be used. it is unclear in the photo documentation how the rafters connected to the top of the wails. There is some existing evidence that layers of 1 x wood material were placed on top of the last round log course, providing a top plate -like surface on which the rafters, with "bird's mouth' notches may have sat A similar system could be utilized using existing lumber or new. Cost of Repairs: Roof framing Use existing lumber as possible and new where needed Includes gales, ridge, rafters, top plate and decking -r 3.4 Building Envelope -Exterior Walls • Exterior Wail Construction Existing Conditions: Poor-r.Good The exterior wall of the cabin is constructed of western yellow pine logs. Existing bark on some of the logs confirms that some of them are Ponderosa pine. The logs making up the first floor are hand4wwn and use a combination of half -dovetail, steeple and square notches to connect,the walls (Flgs.10-14). Although photographic evidence is unclear whether all of the logs are present that existed when the structure was In use, the current sill logs on the north and south elevations are above the level of the iloor)oists. This would suggest that additional logs had been present to support the floor Joists and door frame. However, no evidence of r additional logs has yet been found. The hewn logs were identified as one of the: westem yellow pines. Ponderosa pine (Pins ponderosa). Both the microscopic structure of the wood and remnants of bark were used to Identify the wood spades. tip 1 �• �� l�,hall FIj. 30. FMMMPW a/&mWV. jmw CagW. Example of notching styles from NPS Preservation Brief No. 26 The logs constituting the second story appear to have been added after the Initial construction. They are round and of Irregular taper as opposed to the hand-hewn logs below. These logs were identified as a westem yellow pine. There are various forms of chinking used on the exterior walls. Microscopic examination of wood wedge chinking showed the species to be a westem yellow pine. Wooden pegs penetrate the upper logs at various locations, providing some stability to the second story logs (Fig. 15). 10 1 Moisture content measurements were taken on the logs using a resistance -type meter. Readings were taken near the ends of the logs where moisture could easily move along the end -grain of the log and where deterioration was observed. With the exception of the west wall, no moisture content readings exceeded 20 percent logs on the west elevation near the south wall were found to have moisture contents from 12 to greater than 30 percent. Moisture contents from 20-30 percent indicate areas of concern where sufficient moisture is,present for fungi to be active. Moisture contents above 30 percent are often an indication of advanced decay with internal voids and/or surface deterioration. Based on the moisture readings, the deterioration in the logs and other wood members is the result of past moisture intrusion. With the exception noted on the west elevation, there is insufficient moisture to support active wood decay. Voids in logs, and surface deterioration are the result of past exposure to the elements, a condition exacerbated by the lack of roof covering for several years. Both gable ends located at the site, but not installed on the building, will require some repair to their support structure and to specific wood members making up their construction. East Elevation The logs on the east elevation are, generally, in good condition. They exhibit minor surface deterioration from the combined effects of decay and weathering (Fig. 16), a condition most visible near the north end of logs 1 and 2. The logs have been numbered with one being the lowest log on each elevation. Logs 1-9 are hewn while logs 10 and 11 at the top of the wall are round. Resistance drilling of log 1 revealed that although minor surface deterioration is present, there are no internal voids. Logs 2-9 are weathered but no evidence of decay was found. Logs 10 and 11 have evidence of bark beetle activity, probably present prior to being used in construction of the cabin. Log 11 has significant deterioration due to internal decay extending from the south end to approximately 5' from the north end. The decay has left only approximately 20 percent, remaining cross section. A fruiting body from the wood decay is visible on the exterior of the log (Fig.17). Replacement of this log is recommended. South Elevation The logs on the south elevation are, generally, in good condition. They exhibit minor surface deterioration from the combined effects of decay and weathering. Logs 1-8 . are hewn while logs 9-11 are round. Resistance drilling of log 1 revealed that although minor surface deterioration is present near the east end of the log, there are no internal voids. Logs 2-9 are weathered but no evidence of decay was found. Log 9 as significant deterioration along its length due to decay (Fig. 18). The internal decay has left only approximately 20 percent remaining cross section. Replacement of this log is recommended. l0-11 ? West Elevation The logs on the west elevation are, generally, in good condition. They exhibit minor surface deterioration from the combined effects of decay and weathering, a condition most visible near the north end of logs 1 and 3. Logs 1-8 are hewn while logs 9-11 are round. Log 2 has internal voids near the north end of the log with approximately 50 -70 percent remaining cross-section. The log is in good condition near the south end. Log 2 has a v-notch on the exterior face that does not correspond to any current structural assembly. The reason for the notches is unknown. 11 IF Resistance drilling from the exposed interior wan of the cabin revealed that the interior face of log 2 has decayed, probably due to moisture penetration between the logs and the plaster and lath. Much of the Interior cabin wens are covered with oriented strandboard or plaster and lath (Fig.19). The presence of deterioration on the Interior face of exposed loge on the west and north elevations suggests that other logs have deteriorated on their Interior QxA not visible) faces. This condition likely evolved from lack of roof covering for several years, allowing for moisture intrusion " Into the wan cavity. Log 9 exhibits the initial stages of decay near the south notch. This was the only area of the cabin where the moisture content was sufficient to support active wood decay (Fig. 20). This condition is nkely recent (since the cabin was placed In the courtyard) and the deterioration can be arrested by allowing the wood to dry. North Elevation The logs on the north elevation are, generally, in fair condition. As with the other _ elevations, they exhibit minor surface deterioration from the combined effects of decay and weathering. Logs 1-7 are hand-hewn. Log 8 is hewn but has been placed with the round face exposed. Logs 9 and 10 are round. The second floor Joists are visible between the hewn and round logs and are in fair to good condition. Log 1 exhibits a range of deterkuation and Is a candidate for repair. There is minor Internal deterioration approximately 511Z from the east end of the log. There is decay, both Internal and surface on the log between the location of the windows and extending to the west end of the log. The deterioration. Is most severe below the west window with only 10 percent remaining cross section. The surface deterioration is visible along the length of the log with loss of several Inches of material from the face In several locations. '— Log 2 is severely decayed around the west window. Moving may from the window on either side revealed approximately 75 percent remaining section. Logs 2 and 7 have v-notches on the exterior faces that do not correspond to any current structural assembly. The reason for the notches Is unknown. Log 3 has an Internal void at the west notch but approximately 90 percent of the cross section remains. Similarly, log 4 has a small void 33" east of the west window with approximately 80 percent remaining cross section. Log 5 has internal deterioration between the windows with a minimum section of approximately 20 percent remaining. Log 6 has considerable twist on the section between the windows.

A majority of the chinking remains and consists of strips and blocks of wood material. The daubing has obviously been repaired a number of times as numerous mixes were found, most of which were of a mortar like appearance (ie. lime and send), but very $mail amounts of mud daubing were also present This variation In daubing material Is consistent with historic maintenance techniques in which the daubing would require periodic repair and/or replacement A number of daubing samples were taken from the building for analysis and replication at the Architectural Preservation Institute labs. Treatment Recommendation: After repair and replacement of deteriorated logs and straightening of walls Is complete, chinking and daubing should be repaired and replaced as necessary. Loose daubing should be removed, and missing chinking should be replaced with similar material of same shape and wood species. After gaps are filled with oinking, new daubing mix, based on the recipe provided below, should be applied. Examination of the building Indicates that the majority, if not all, daubing will require replacement to ensure all the material has good adhesion to the logs. The daubing "recipe" is based on information obtained by the Architectural Preservation Institute by conducting a gravimetric mortar mix. The samples were crushed then subjected to an approximately 12% solution of hydrochloric acid in order to dissolve any lime (calcium carbonate) binder. After the binder (lime) was ' Chinking - wood strips, planks, or other material placed between logs. 2 Daubing - mortar or plaster -like material placed over chinking.

Daubing Recipe: 6 parts sand (LaFarge Ridge Pit, East Fort Collins) 4 parts lime 1 part federal cement Daubing to be applied based on information provided In the National Park Service's Preservation Brief 26: The Preservation and Repair of Historic Log Buildings Included in this report. Examples of chinking and daubing techniques from NPS Preservation Brief No. 26 Cost of Repairs: Replace missing chinking Replace missing daubing • Exterior Masonry Existing Conditions: None Historic photographs, c.1988, (Fig. 22 &.9) indicate that the cabin had a brick chimney extending from the roof through the second story floor (Fig. 9), but none show the area on the first story where the chimney would have penetrated from the second story. The chimney may have extended through the first floor to some kind of stone foundation below the cabin, or have sat on a wooden shelf, current evidence is unclear. As there is no indication in the interior that there was a fireplace, this chimney most likely provided venting for a wood stove. Inspection of the floor at this location was not possible due to debris. None of the original brick material remains. Treatment Recommendation: The historic photos dearly show the design of the original chimney and that it extended through the second story space and floor. This element should be reconstructed as It provides a significant detail to both the exterior and Interior of the structure. 14 M 1...1 lo The second story floor has a square cutout indicating that the chimney penetrated down to the first floor. As stated before, the chimney either extended through the first floor to a stone foundation orwas supported by a wooden shelf. Since there is not adequate evidence of either detail, a decision will need to be made as to which detail to use. A stove appropriate to the period of interpretation (1920's) could be installed, with venting provided by the reconstructed chimney. Cost of Repairs: Reconstruct 29 h, 18• x 180 brick chimney with flue Install new wood burning stove • Exterior Windows, Doors, Hardware, and Trim Existing Conditions & Treatment Recommendations: All the windows appear to have been four -paned (four over four), double -hung, sash windows. There are six (6) window openings in all, two on both the north and south . elevations and one In either gable end, and two exterior doors, one on each of the east and south elevations. The door And window trim consists of 10 thick boards, generally In fair to poor condition. Most of the trim is weathered and warped. Some material is missing. A sample of the window trim was Identified as white pine. There are a number of window sashes located inside the building which are more than likely the original window material (Fig. 31). What little evidence of paint exists indicates that the exterior trim was painted white at one time. The door on the east elevation has warped trim on the south side (Figure 29 a & b). The trim on the north side of the Jamb has minor deterioration. The sill has deteriorated and needs replacement. The windows on the south elevation have broken and warped sills with minor deterioration due to decay. Some of the side trim is missing. The left hand window #1 (Fig. 23) on the south elevation has been covered on the interior with lath and plaster.

However, according to available photos (c. 1988), the roof framing system consisted of milled 2x4 rafters with collar beams. Other photos (Fig. 32a) show sheathing consisting of wood planks of various widths with random width gaps between. The roofing material was corrugated galvanized steel similar to the Strongbam material available today (Fig. 32b). The roof pitch is approximateiy 6:12. Treatment Recommendation: Reconstruct the roof framing system using salvaged lumber located in the east room, if possible. Provide new wood 1" thick plank sheathing and roofing material. Replacement sheathing should resemble the plank sheathing shown In photo documentation. Strongbam corrugated galvanized steel roofing with a metal ridge cap can be used to replicate the roofing shown In the photo documentation. This material Is available from Hutchison Western located at 7460 Highway 85, Commerce City, CO. An alternate roofing material would be treated cedar shingle. Although the photo documentation available does not Indicate the structure had cedar shingles, other Information such as oral histories may be able to provide that information.

If at a later date the Fort Collins Museum finds that one is necessary due to excessive water run -Off from the roof accelerating decay of the building. a rounded. galvanized steel gutter system would be most appropriate. -- Cost of Repairs: $0 3.6 Interior Finishes • Wall Finish Material -1st Floor Existing Conditions: Poor The Interior walls are finished in lath and plaster, with the stair well wails being _ constructed of tongue & groove wood planking. The plaster waft are in serious disrepair due to exposure to moisture and the moving of the cabin (Na. 33-39). The wood plank wails are in fair condition. These walls have remains of multiple layers of wallpaper with paint below, of of which Is In poor condition (Fig. 40-52). Historic Photos (o. 1988) (Fig. 53 & 54) iodic ate that the plaster wells also had wallpaper applied. Samples were taken of the plaster material for analysis in the Architectural Preservation Institute lab. -- Treatment Recommendation: Due to the extensive damage to the lath and plaster, new lath and plaster is required. Plaster should consist of a gypsum plaster with horsehair in the mixture, df.possibie, r to replicate existing. Wallpaper should be. reapplied throughout the first floor that either replicates the paper determined to coincide with the 1920's era, or be one chosen which closely resembles it. Some existing wallpaper shouid,remakr In place (possibly with a glass cover), to show visitors the many layers of paper applied to the interior over the years. Install new wood base board throughout 1st floor. Wall Finish Material - 2nd Floor Existing Conditions: None The c.1988 photos do not indicate any Interior wall finishes on the 2nd floor (Fig. 55) Treatment Recommendation: None, leave second story with no interior finishes. Cost of Repairs: Apply new wood lath Apply new gypsum plaster Replication wallpaper (east room) Replication wallpaper (west room) .- Install new wood base board 18 • Calling Finish Materials -1 at floor Existing Conditions: None There are currently no finish materials on the ceiling, only the exposed second floor Joists and second floor wood subfloodng material. Historic photos (c. 1988) show, that at that time, the ceiling consisted pf a finished ceiling (most likely lath and plaster), painted or papered in a light color (Fig. 56). Treatment Recommendation: Reinstall lath and plaster ceiling per the historic photos and apply paint or wall paper of a light color or one matching paint samples removed from other interior elements. Cost of Repairs: Apply new wood lath Apply new gypsum plaster Paint ceiling Paper ceiling Flooring Material Existing Conditions: Poor First Floor. The wearing surface of the floor in the east room is 314- thick tongue -and -groove flooring, 3" wide (Fig. 57). Flooring (which may have been subfloodng) in the west room varies in width. Much of the flooring was inaccessible due to storage of lumber from the cabin on the first floor but what was visible showed signs of weathering and minor splitting due to exposure to the elements over time. Moisture content readings on the wood joists and flooring were less than 20 percent. A small amount of jute backed linoleum was found at the 1st floor stalr landing. This linoleum may have covered the west room also, yet none of the material currently remains (Fig. 58). Second Floor. The wearing surface consists of nominal V thick lumber laid perpendicular to the Joists (Fig. 59). The wearing surface also serves as the sub -floor. There Is currently no subfloor. The floorboards exhibit considerable warp due to prolonged exposure to the elements and will need replacement should the second floor be made accessible to the public. Treatment Recommendation: Repair flooring in east room as needed. Reinstall wood flooring in west room, similar to east room flooring, or install linoleum (pricing is based on installing new wood floor as costs for replicating linoleum were not available and extent of original linoleum Installation unknown). Install new wood subfloor and wearing surface flooring on second story.

Myers >>Architectural or Historical Si nificance »Physical Evaluation *Repair Class I: Routine Maintenance »Repair Class II: Stabilization »Repair Class III: Splices and Parts Replacement »Weatherization >>Window Replacement >>Conclusion >>Additional Readies National Park Service The windows on many historic buildings are an important aspect of the architectural character of those buildings. Their design, craftsmanship, or other qualities may make them worthy of preservation. This is self-evident for ornamental windows, but it can be equally true for warehouses or factories where the windows may be the most dominant visual element of an otherwise plain building. Evaluating the significance of these windows and planning for their repair or replacement can be a complex process involving both objective and subjective considerations. The Secretary of the Interior's Standards for Rehabilitation and the accompanying guidelines, call for respecting the significance of original materials and features, repairing and retaining them wherever possible, and when necessary, replacing them in kind. This Brief is based on the issues of significance and repair which are implicit in the standards, but the primary emphasis is on the technical issues of planning for the repair of windows including evaluation of their physical condition, techniques of repair, and design considerations when replacement is necessary. Much of the technical section presents repair techniques as an instructional guide for the do-it-yourselfer. The information will be useful, however, for the architect, contractor, or developer on large-scale projects. It presents a methodology for approaching the evaluation and repair of existing windows, and considerations for replacement, from which the professional can develop alternatives and specify appropriate materials and procedures. Architectural or Historical Significance Evaluating the architectural or historical significance of windows is the first step in planning for window treatments, and a general understanding of the function and history of windows is vital to making a proper evaluation. As a part of this evaluation, one must httn-Hwww2_cr nns onv/tn.c/hriefc/hriefll9 him ................. zran/Inm Preservation Brief 9: The Repair of Historic Wooden Windows Page 2 of 11 consider four basic window. functions: admitting light to the interior spaces, providing fresh air and ventilation to the interior, providing a visual link to the outside world, and enhancing the appearance of a building. No single factor can be disregarded when planning window treatments; for example, attempting to conserve energy by closing up or reducing the size of window openings may result in the use of more energy by increasing electric lighting loads and decreasing passive solar heat -gains. especially on simple facades such as this mill building. Replacement of the multi -pane windows with larger panes could dramatically alter the appearance of the building. Photo: NPS files. element. Historically, the first windows in early American houses were casement windows; that is, they were hinged at the side and opened outward. In the beginning of the eighteenth century single - and double -hung windows were introduced. Subsequently many styles of these vertical sliding sash windows have come to be associated with specific building periods or architectural styles, and this is an important - consideration in determining the significance of windows, especially on a local or regional basis. Site -specific, regionally oriented architectural comparisons should be made to determine the significance of windows in question. Although such comparisons may focus on specific window types and their details, the ultimate determination of significance should be made within the context of the whole building, wherein the windows are one architectural After all of the factors have been evaluated, windows should be considered significant to a building if they: 1) are original, 2) reflect the original design intent , for the building, 3) reflect period or regional styles or building practices, 4) reflect changes to the building resulting from major periods or events, or 5) are examples of exceptional craftsmanship or design. Once this evaluation of significance has been completed, it is possible to proceed with planning appropriate treatments, beginning with an investigation of the physical condition of the windows. Physical Evaluation The key to successful planning for window treatments is a careful evaluation of existing physical conditions on a unit -by -unit basis. A graphic or photographic system may be devised to record existing conditions and illustrate the scope of any necessary repairs. Another effective tool is a window schedule which lists all of the parts of each window unit. Spaces by each part allow notes on existing conditions and repair instructions. When such a schedule is completed, it indicates the precise tasks to be performed in the repair of each unit and becomes a part of the specifications. In any evaluation, one should note at a minimum: e 1) window location e 2) condition of the paint e 3) condition of the frame and sill e 4) condition of the sash (rails, stiles and muntins) 5) glazing problems ht.trr//www? cr nns.lsnv/tn-/hrief.�/hriefll9.htm 3/10/2003 Preservation Brief 9: The Repair of Historic Wooden Windows Page 3 of I I e 6) hardware, and 7) the overall condition of the window (excellent, fair, poor, and so forth) Many factors such as poor design, moisture, vandalism, insect attack, and lack of maintenance can contribute to window deterioration, but moisture is the primary contributing factor in wooden window decay. All window units should be inspected to see if water is entering around the edges of the fr�:me and, if so, the joints or seams should be caulked to eliminate this danger. The glazing putty should be checked for cracked, loose, or missing sections which allow water to saturate the wood, especially at the joints. The back putty on the interior side of the pane should also be inspected, because it creates a seal which prevents condensation from running down into the joinery. The sill should be examined to insure that it slopes downward away from the building and allows water to drain off. In addition, it may be advisable to cut a dripline along the underside of the sill. This almost invisible treatment will insure proper water runoff, particularly if the bottom of the sill is flat. Any conditions, including poor original design, which permit water to come in contact wit'i the wood or to puddle on the sill must be corrected as they contribute to deteriorat on of the window. One clue to the location of areas of excessive moisture is the condition of the paint; therefore, each window should be examined for areas of paint failure. Since excessive moisture is detrimental to the paint bond, areas of paint blistering, cracking, flaking, and peeling usually identify points of water penetration, moisture saturation, and potential deterioration. Failure of the paint should not, however, be mistakenly interpreted as a sign that the wood is in poor condition and hence, irreparable. Wood is frequently in sound physical condition beneath unsightly paint. After noting areas of paint failure, the next step is to inspect the condition of the wood, particularly at the points identified during the paint examination. ,eterioration of poorly maintained windows usually f ;ins on horizontal surfaces and at Joints, where %- er can collect and saturate the wood. Photo: t ?S files. Each window should be examined for operational soundness beginning with the lower portions of the frame and sash. Exterior rainwater and interior condensation can flow downward along the window, entering and collectii,e at points where the flow is blocked. The sill, joints between the sill and jamb, orners of the bottom rails and muntin joints are typical points where water collect; and deterioration begins. The operation of the window (continuous opening and c:osing over the years and seasonal temperature changes) weakens the joints, causing , iovement and slight separation. This process makes the joints more vulnerable to rater which is readily absorbed into the endgrain of the wood. If severe deterioration ex!sts in these areas, it will usually be apparent on visual inspection, but other less severely deteriorated areas of the wood may be tested by two traditional methods using a call ice pick. An ice pick or an awl may be used to test wood for soundness. The technique is simply to jab the pick into a wetted wood surface at an arg!e and pry up a small section of the wood. Sound wood will separate in long fibrous sp' .ters, but decayed wood will lift up in short irregular pieces due to the breakdown of f'l er strength. Another method of testing for soundness consists of pushing a sharp object into the wood, perpendicular to the surface. If deterioration : as begun from the hidden side of a http://www2.cr.nps.gov/tpsibriefs/briefO9.htm 3/30/2003 Preservation Brief 9: The Repair of Historic Wooden Windows i i Page 4 of 11 member and the core is badly decayed, the visible surface may appear to be sound wood. Pressure on the probe can force it through an apparently sound skin to penetrate deeply into decayed wood. This technique is especially useful for checking sills where visual access to the underside is restricted. Following the inspection and analysis of the results, the scope of the necessary repairs will be evident and a plan for the rehabilitation can be formulated. Generally the actions necessary to return a window to "like new" condition will fall into three broad categories: 1) routine maintenance procedures, 2) structural stabilization, and 3) parts replacement. These categories will be discussed in the following sections and will be referred to respectively as Repair Class I, Repair Class II, and Repair Class III. Each successive repair class represents an increasing level of difficulty, expense, and work time. Note that most of the points mentioned in Repair Class I are routine 2 maintenance items and should be provided in a regular maintenance program for any building. The neglect of these routine items can contribute to many common window problems. Before undertaking any of the repairs mentioned in the following sections all sources of moisture penetration should be identified and eliminated, and all existing decay fungi destroyed in order to arrest the deterioration process. Many commercially available fungicides and wood preservatives are toxic, so it is extremely important to follow the manufacturer's recommendations for application, and store all chemical materials away from children and animals: After fungicidal and preservative treatment the windows may be stabilized, retained, and restored with every expectation for a long service life. Repair Class I: Routine Maintenance Repairs to wooden windows are usually labor intensive and relatively uncomplicated. On small scale projects this allows the do-it-yourselfer to save money by repairing all or part of the windows. On larger projects it presents the opportunity for time and money which might otherwise be spent on the removal and replacement of existing windows, to be spent on repairs, subsequently saving all or part of the material cost of new window units. Regardless of the actual costs, or who performs the work, the evaluation process described earlier will provide the knowledge from which to specify an appropriate work program, establish the work element priorities, and identify the level of skill needed by the labor force. The routine maintenance required has many layers of paint, soma to upgrade a window to "like new" cracked and missing putty, slight separation at the Joints, broken sash condition normally includes the cords, and one cracked pane. Photo: following steps: 1) some degree NPS files. of interior and exterior paint removal, 2) removal and repair of sash (including reglazing where necessary), 3) repairs to the frame, 4) weatherstripping and reinstallation of the sash, and S) repainting. These operations are illustrated for a typical double -hung wooden window, but they may be adapted to other window types and styles as applicable. httn'//www7 (-.r nns.vnv/tn.q/hriefs/hriefT)9.htm 3/30/2003 Preservation brief 9: '1 he Repair of Historic Wooden Windows Page ) of i t Historic windows have usually acquired many layers of paint over time. Removal of excess layers or peeling and flaking paint will facilitate operation of the window and restore the clarity of the original detailing. Some degree of paint removal is also necessary as a first step in the proper surface preparation for subsequent refinishing (if paint color analysis is desired, it should be conducted prior to the onset of the paint removal). There are several safe and effective techniques for removing paint from wood, depending on the amount of paint to be removed. r Paint removal should I begin on the interior „- y frames, being careful After removing paint from the to remove the paint seam between the interior stop from the interior stop and the jamb, the stop can be pried out and gradually worked and the parting bead, loose using a pair of putty particularly althe knives as shown.

This can be accomplished by running a utility knife along the length of the seam, breaking Sash can be removed and repaired in a convenient the paint bond. It will then be much easier to work area. Paint is being removed from this sash with remove the stop, the parting bead and the a hot air gun. Photo: NPS files. sash. The interior stop may be initially loosened from the sash side to avoid visible scarring of the wood and then gradually pried loose using a pair of putty knives, working up and down the stop in small increments. With the stop removed, the lower or interior sash may be withdrawn. The sash cords should be detached from the sides of the sash and their ends may be pinned with a nail or tied in a knot to prevent them from falling into the weight pocket. Removal of the upper sash on double -hung units is similar but the parting bead which holds it in place is set into a groove in the center of the stile and is thinner and more delicate than the interior stop. After removing any paint along the seam, the parting bead should be carefully pried out and worked free in the same manner as the interior stop. The upper sash can be removed in the same manner as the lower one and both sash taken to a convenient work area (in order to remove the sash the interior stop and parting bead need only be removed from one side of the window). Window openings can be covered with polyethylene sheets or plywood sheathing while the sash are out for repair. The sash can be stripped of paint using appropriate techniques, but if any heat treatment is used, the glass should be removed or protected from the sudden temperature change which can cause breakage. An overlay of aluminum foil on gypsum board or asbestos can protect the glass from such rapid temperature change. It is important to protect the glass because it may be historic and often adds character to the window. Deteriorated putty should be removed manually, taking care not to damage the wood along the rabbet. If the glass is to be removed, the glazing points which hold the glass in place can be extracted and the panes numbered and removed for cleaning and reuse in the same openings. With the glass panes out, the remaining putty can be removed and the sash can be sanded, patched, and primed with a preservative primer. Hardened putty in the rabbets may be softened by heating with a soldering iron at the point of removal. Putty remaining on the glass may be softened by soaking the panes in linseed oil, and then removed with less risk of breaking the glass. Before reinstalling the glass, a bead of glazing compound or linseed oil putty should be laid around the rabbet http://www2.cr.nps.gov/tps/briefs/br-ief09.htm 3/30/2003 SECTION 00300 PROJECT: RESTORATION OF FRANZ-SMITH CABIN; Bid No. 5787 Place Date: May 29th 2003 In compliance with your Invitation to Bid dated April 18'b 2003 and subject to all conditions thereof, the undersigned Empire Carnentry a Limited Liability Company authorized to do business in the State of Colorado hereby proposes to furnish and do everything required by the Contract Documents to which this refers for the construction of all items listed on the following Bid Schedule or Bid Schedules. 2.

Glazing compound should only be used on wood which has been brushed with linseed oil and primed with an oil based primer or paint. The pane is then pressed into place and the glazing points are pushed into the wood around the perimeter of the pane. The final glazing compound or putty is applied and beveled to complete the seal. The sash can be refinished as desired on the inside and painted on the outside as soon as a "skin" has formed on the putty, usually in 2 or 3 days. Exterior paint should cover the beveled glazing compound or putty and lap over onto the glass slightly to complete a weather -tight seal. After the proper curing times have elapsed for paint and putty, the sash will be ready for reinstallation. While the sash are out of the frame, the condition of the wood -in the jamb and sill can be evaluated. Repair and refinishing of the frame may proceed concurrently with repairs to the sash, taking advantage of the curing times for the paints and putty used on the sash. One of the most common work items is the replacement of the sash cords with new rope cords or with chains. The weight pocket is frequently accessible through a door on the face of the frame near the sill, but if no door exists, the trim on the interior face may be removed for access. Sash weights may be increased for easier window operation by elderly or handicapped persons. Additional repairs to the frame and sash may include consolidation or replacement of deteriorated wood. Techniques for these repairs are discussed in the following sections. The operations just discussed summarize the efforts necessary to restore a window with minor deterioration to "like new" condition. The techniques can be applied by an unskilled person with minimal training and experience. To demonstrate the practicality of this approach, and photograph it, a Technical Preservation Services staff member repaired a wooden double -hung, two over two window which had been in service over ninety years. The wood was structurally sound but the window had one broken pane, many layers of paint, broken sash cords and inadequate, worn-out weatherstripping. The staff member found that the frame could be stripped of paint and the sash removed quite easily. Paint, putty and glass removal required about one hour for each sash, and the reglazing of both sash was accomplished in about one hour.

Many windows will show some additional degree of physical deterioration, especially in the vulnerable areas mentioned earlier, but even badly damaged windows can be repaired using simple processes. Partially decayed wood can _ be waterproofed, patched, built-up, or consolidated and then painted to achieve a sound condition, good appearance, and greatly extended life. Three techniques for repairing http://www2.cr.nps.gov/tpsibriefs/briefO9.htm 3/30/2003 `� Preservation Brief 9: The Repair of Historic Wooden Windows Page / of 11 partially decayed or weathered wood are discussed in this section, and all three can be accomplished using products available at most hardware stores. One established technique for repairing wood which is split, checked or shows signs of rot, is to: 1) dry the wood, 2) treat decayed areas with a fungicide, 3) waterproof with two or three applications of boiled linseed oil (applications every 24 hours), 4) fill cracks and holes with putty, and 5) after a "skin" forms on the putty, paint the surface. Care should be taken with the use of fungicide which is toxic. Follow the manufacturers' directions and use only on areas which will be painted. When using any technique of building up or patching a flat surface, the finished surface should be sloped slightly to carry water away from the window and not allow it to puddle. Caulking of the joints between the sill and the jamb will help reduce further water penetration. When sills or other members exhibit surface weathering they may also be built-up using wood putties or homemade mixtures such as sawdust and resorcinol glue, or whiting and varnish. These mixtures can be built up in successive layers, then sanded, primed, and painted. The same caution about proper slope for flat surfaces applies to this technique. v z - Wood may also be strengthened and stabilized by consolidation, using semirigid epoxies which This illustrates a two-part expoxy patching saturate the porous decayed wood and then compound used fill the surface of a weathered sill andd rebuild the missing edge. harden. The surface of the consolidated wood can When the epoxy cures, it can be sanded smooth then be filled with a semirigid epoxy patching and painted to achieve a durable and waterproof compound, sanded and painted. Epoxy patching repair. Photo: NPS files. compounds can be used to build up missing sections or decayed ends of members. Profiles can be duplicated using hand molds, which are created by pressing a ball of patching compound over a sound section of the profile which has been rubbed with butcher's wax. This can be a very efficient technique where there are many typical repairs to be done. The process has been widely used and proven in marine applications; and proprietary products are available at hardware and marine supply stores. Although epoxy materials may be comparatively expensive, they hold the promise of being among the most durable and long lasting materials available for wood repair. More information on epoxies can be found in the publication "Epoxies for Wood Repairs in Historic Buildings," cited in the bibliography. Any of the three techniques discussed can stabilize and restore the appearance of the window unit. There are times, however, when the degree of deterioration is so advanced that stabilization is impractical, and the only way to retain some of the original fabric is to replace damaged parts. Repair Class III: Splices and Parts Replacement When parts of the frame or sash are so badly deteriorated that they cannot be stabilized there are methods which permit the retention of some of the existing or original fabric. These methods involve replacing the deteriorated parts with new matching pieces, or splicing new wood into existing members. The techniques require more skill and are more expensive than any of the previously discussed alternatives. It is necessary to remove the sash and/or the affected parts of the frame and have a carpenter or http://www2.cr.nps.gov/tps/briefs/briefD9.htm 3/30/2003 Preservation Brief 9: The Repair of Historic Wooden Windows Page 8 of 11 E woodworking mill reproduce the damaged or missing parts. Most millwork firms can '- duplicate parts, such as muntins, bottom rails, or sills, which can then be incorporated into the existing window, but it may be necessary to shop around because there are T several factors controlling the practicality of this approach. Some woodworking mills do not like to repair old sash because nails or other foreign objects in the sash can damage expensive knives (which cost far more than their profits on small repair jobs); others do not have cutting knives to duplicate muntin profiles. Some firms prefer to concentrate _ r on larger jobs with more profit potential, and some may not have a craftsman who can duplicate the parts. A little searching should locate a firm which will do the job, and at a reasonable price. If such a firm does not exist locally, there are firms which undertake this kind of repair and ship nationwide. It is possible, however, for the advanced do-it- yourselfer or craftsman with a table saw to duplicate moulding profiles using techniques discussed by Gordie Whittington in "Simplified Methods for Reproducing Wood Mouldings," Bulletin of the Association for Preservation Technology, Vol. III, No. 4, 1971, or illustrated more recently in The Old House, Time -Life Books, Alexandria, Virginia, 1979. The repairs discussed in this section involve window frames which may be in very deteriorated condition, possibly requiring removal; therefore, caution is in order. The actual construction of wooden -window frames and sash is not complicated. Pegged mortise and tenon units can be disassembled easily, if the units are out of the building. The installation or connection of some frames to the surrounding structure, especially masonry walls, can complicate the work immeasurably, and may even require dismantling of the wall. It may be useful, therefore, to take the following approach to frame repair: 1) conduct regular maintenance of sound frames to achieve the longest life possible, 2) make necessary repairs in place, wherever possible, using stabilization and splicing techniques, and 3) if removal is necessary, thoroughly investigate the -- structural detailing and seek appropriate professional consultation. Another alternative may be considered if parts replacement is required, and that is sash — replacement. If extensive replacement of parts is necessary and the job becomes prohibitively expensive it may be more practical to purchase new sash which can be installed into the existing frames. Such sash are available as exact custom reproductions, reasonable facsimiles (custom windows with similar profiles), and contemporary wooden sash which are similar in appearance. There are companies which still manufacture high quality wooden sash which would duplicate most historic sash. A few calls to local building suppliers may provide a source of appropriate replacement — sash, but if not, check with local historical associations, the state historic preservation office, or preservation related magazines and supply catalogs for information. If a rehabilitation project has a large number of windows such as a commercial building or an industrial complex, there may be less of a problem arriving at a solution. Once the evaluation of the windows is completed and the scope of the work is known, there may be a potential economy of scale. Woodworking mills may 'be interested in the work from a large project; new sash in volume may be considerably less expensive per unit; crews can be assembled and trained on site to perform all of the window repairs; and a few .. extensive repairs can be absorbed (without undue burden) into the total budget for a large number of sound windows. While it may be expensive for the average historic home owner to pay seventy dollars or more for a mill to grind a custom knife to duplicate four or five bad muntins, that cost becomes negligible on large commercial projects which may have several hundred windows. Most windows should not require the extensive repairs discussed in this section. The ones which do are usually in buildings which have been abandoned for long periods or have totally lacked maintenance for years. It is necessary to thoroughly investigate the http://www2.cr.nps.gov/tps/briefs/brief09.htm 3/30/2003 ri cJA;L V d .lull 011Gi, Y. i ilC NIZpall V i rllsturlu VV UVUGii VV IIIUU W J r ase 7 UL 1 1 alternatives for windows which do require extensive repairs to arrive at a solution which retains historic significance and is also economically feasible. Even for projects requiring repairs identified in this section, if the percentage of parts replacement per window is low, or the number of windows requiring repair is small, repair can still be a cost effective solution. Weatherization A window which is repaired should be made as energy efficient as possible by the use of appropriate weatherstripping to reduce air infiltration. A wide variety of products are available to assist in this task. Felt may be fastened to the top, bottom, and meeting rails, but may have the disadvantage of absorbing and holding moisture, particularly at the bottom rail. Rolled vinyl strips may also be tacked into place in appropriate locations to reduce infiltration. Metal strips or new plastic spring strips may be used on the rails and, if space permits, in the channels between the sash and jamb. Weatherstripping is a historic treatment, but old weatherstripping (felt) is not likely to perform very satisfactorily. Appropriate contemporary weatherstripping should be considered an integral part of the repair process for windows. The use of sash locks installed on the meeting rail will insure that the sash are kept tightly closed so that the weatherstripping will function more effectively to reduce infiltration. Although such locks will not always be historically accurate, they will usually be viewed as an acceptable contemporary modification in the interest of improved thermal performance. Many styles of storm windows are available to improve the thermal performance of existing windows. The use of exterior storm windows should be investigated whenever feasible because they are thermally efficient, cost-effective, reversible, and allow the retention of original windows (see "Preservation Briefs: 3"). Storm window frames may be made of wood, aluminum, vinyl, or plastic; however, the use of unfinished aluminum storms should be avoided. The visual impact of storms may be minimized by selecting colors which match existing trim color. Arched top storms are available for windows with special shapes. Although interior storm windows appear to offer an attractive option for achieving double glazing with minimal visual impact, the potential for damaging condensation problems must be addressed. Moisture which becomes trapped between the layers of glazing can condense on the colder, outer prime window, potentially leading to deterioration. The correct approach to using interior storms is to create a seal on the interior storm while allowing some ventilation around the prime window. In actual practice, the creation of such a durable, airtight seal is difficult. Window Replacement Although the retention of original or existing windows is always desirable and this Brief is intended to encourage that goal, there is a point when the condition of a window may clearly indicate replacement. The decision process for selecting replacement windows should not begin with a survey of contemporary window products which are available as replacements, but should begin with a look at the windows which are being replaced. Attempt to understand the contribution of the window(s) to the appearance of the facade including: 1) the pattern of the openings and their size; 2) proportions of the frame and sash; 3) configuration of window panes; 4) muntin profiles; 5) type of wood; 6) paint color; 7) characteristics of the glass; and 8) associated details such as arched tops, hoods, or other decorative elements. Develop an understanding of how the window http://www2.cr.nps.gov/tps/briefsfbriefO9.htm 3/30/2003 F(a Preservation Brief 9: The Repair of Historic Wooden Windows Page 10 of 11 L P reflects the period, style, or regional characteristics of the building, or represents technological development. Armed with an awareness of the significance of the existing window, begin to search for r a replacement which retains as much of the character of the historic window as possible. There are many sources of suitable new windows. Continue looking until an acceptable replacement can be found. Check building supply firms, local woodworking mills, carpenters, preservation oriented magazines, or catalogs or suppliers of old building materials, for product information. Local historical associations and state historic preservation offices may be good sources of information on products which have been used successfully in preservation projects. p Consider energy efficiency as one of the factors for replacements, but do not let it -- dominate the issue. Energy conservation is no excuse for the wholesale destruction of historic windows which can be made thermally efficient by historically and aesthetically acceptable means. In fact, a historic wooden window with a high quality storm window .. added should thermally outperform a new double -glazed metal window which does not have thermal breaks (insulation between the inner and outer frames intended to break the path of heat flow). This occurs because the wood has far better insulating value than the metal, and in addition many historic windows have high ratios of wood to glass, thus reducing the area of highest heat transfer. One measure of heat transfer is the U-value, the number of Btu's per hour transferred through a square foot of material. When comparing thermal performance, the lower the U-value the better the performance. According to ASHRAE 1977 Fundamentals, the U-values for single glazed wooden windows range from 0.88 to 0.99. The addition of a storm window should reduce these figures to a range of 0.44 to 0.49. A non -thermal break, double -glazed metal window _ has a U-value of about 0.6. Conclusion Technical Preservation Services recommends the retention and repair of original 1 windows whenever possible. We believe that the repair and weatherization of existing wooden windows is more practical than most people realize, and that many windows are _ unfortunately replaced because of a lack of awareness of techniques for evaluation, repair, and weatherization. Wooden windows which are repaired and properly maintained will have greatly extended service lives while contributing to the historic character of the building. Thus, an important element of a building's significance will have been preserved for the future. Additional Reading ASHRAE Handbook 1977 Fundamentals.

The handwriting of the artisans, the taste of the original occupants, and the evolving styles of decoration are embodied in the fabric of the building. From modest farmhouses to great buildings, regardless of the ethnic origins of the occupants, plaster has traditionally been used to finish interior walls. A versatile material, plaster could be applied over brick, stone, half-timber, or frame construction. It provided a durable surface that was easy to clean and that could be. applied to flat or curved walls and ceilings. Plaster could be treated in any number of ways: it could receive stenciling, decorative painting, wallpaper, or whitewash. This variety and the adaptability of the material to nearly any building size, shape, or configuration meant that plaster was the wall surface chosen for nearly all buildings until the 1930s or 40s. Plaster was used as the Interior surface coating of this elegant 1911 church located in Eugene, Oregon. Photo: NPS files. Historic plaster may first appear so fraught with problems that its total removal seems the only alternative. But there are practical and historical reasons for saving it. First, three - coat plaster is unmatched in strength and durability. It resists fire and reduces sound transmission. Next, replacing plaster is expensive. A building owner needs to think carefully about the condition of the plaster that remains; plaster is often not as badly damaged as it first appears. Of more concern to preservationists, however, original lime and gypsum plaster is part of the building's historic fabric --its smooth troweled or textured surfaces and subtle contours evoke the presence of America's earlier craftsmen. Plaster can also serve as a plain surface for http://www2.cr.nps.gov/tps/briefs/brief2 I.htm 3/30/2003 Preservation Brief 21: Repairing Historic Flat Plaster --Walls and Ceilings Page 2 of 15 irreplaceable decorative finishes. For both reasons, plaster walls and ceilings contribute to the historic character of the interior and should be left in place and repaired if at all possible. The approaches described in this Brief stress repairs using wet plaster, and traditional materials and techniques that will best assist the preservation of historic plaster walls and ceilings --and their appearance. Dry wall repairs are not included here, but have been written about extensively in other contexts. Finally, this Brief describes a replacement option when historic plaster cannot be repaired. Thus, a veneer plaster system is discussed rather than dry wall. Veneer systems include a coat or coats of wet plaster --although thinly applied --which can, to a greater extent, simulate traditional hand -troweled or textured finish coats. This system is generally better suited to historic preservation projects than dry wall. To repair plaster, a building owner must often enlist the help of a plasterer. Plastering is a skilled craft, requiring years of training and special tools. While minor repairs can be undertaken by building owners, most repairs will require the assistance of a plasterer. Historical Background Plasterers in North America have relied on two materials to create their handiwork --lime and gypsum. Until the end of the 19th century, plasterers used lime plaster. Lime plaster was made from four ingredients: lime, aggregate, fiber, and water. The lime came from ground -and -heated limestone or oyster shells; the aggregate from sand; and the fiber from cattle or hog hair. Manufacturing changes at the end of the 19th century made it possible to use gypsum as a plastering material. Gypsum and lime plasters were used in combination for the base and finish coats during the early part of the 20th century; gypsum was eventually favored because it set more rapidly and, initially, had a harder finish. The builders of this mid-18th century house installed the baseboard molding first then applied a mud and horse hair plaster. Lime was used for the finish plaster. Photo: NPS files. Not only did the basic plastering material change, but the method of application changed also. In early America, the windows, doors, and all other trim were installed before the plaster was applied to the wall. Generally the woodwork was prime -painted before plastering. Obtaining a plumb, level wall, while working against built-up moldings, must have been difficult. But sometime in the first half of the 19th century, builders began installing wooden plaster "grounds" around windows and doors and at the base of the wall. Installing these grounds so that they were level and plumb made the job much easier because the plasterer could work from a level, plumb, straight surface. Woodwork was then nailed to the "grounds" after the walls were plastered. Evidence of plaster behind trim is often an aid to dating historic houses, or to discerning their physical evolution. Lime Plaster When building a house, plasterers traditionally mixed bags of quick lime with water to "hydrate" or "slake" the lime. As the lime absorbed the water, heat was given off. When the heat diminished, and the lime and water were thoroughly mixed, the lime putty that resulted was used to make plaster. http://www2.cr.nps.gov/tpsibriefs/brief2 Lhtm 3/30/2003 Preservation Brief 21: Repairing Historic Flat Plaster --Walls and Ceilings Page 3 of 15 When lime putty, sand, water, and animal hair were mixed, the mixture provided the plasterer with "coarse stuff." This mixture was applied in one or two layers to build up the wall thickness. But the best plaster was done with three coats. The first two coats made up the coarse stuff; they were the scratch coat and the brown coat. The finish plaster, called "setting stuff," contained a much higher proportion of lime putty, little aggregate, and no fiber, and gave the wall a smooth white surface finish. Compared to the 3/8-inch-thick layers of the scratch and brown coats, the finish coat was a mere 1/8-inch thick. Additives were used for various finish qualities. For example, fine white sand was mixed in for a "float finish." This finish was popular in the early 1900s. (If the plasterer raked the sand with a broom, the plaster wall would retain swirl marks or stipples.) Or marble dust was added to create a hard -finish white coat which could be smoothed and polished with a steel trowel. Finally, a little plaster of Paris, or "gauged stuff," was often added to the finish plaster to accelerate the setting time. Although lime plaster was used in this country until the early 1900s, it had certain disadvantages. A plastered wall could take more than a year to dry; this delayed painting or papering. In addition, bagged quick lime had to be carefully protected from contact with air, or it became inert because it reacted with ambient moisture and carbon dioxide. Around 1900, gypsum began to be used as a plastering material. Gypsum Plaster Schiflerstadt, a simple house of German origin that dates to 1756, utilized plaster for both flat and curved walls. The building is located In Frederick, Maryland Photo: NPS flies. Gypsum begins to cure as soon as it is mixed with water. It sets in minutes and completely dries in two to three weeks. Historically, gypsum made a more rigid plaster and did not require a fibrous binder. However it is difficult to tell the difference between lime and gypsum plaster once the plaster has cured. Despite these desirable working characteristics, gypsum plaster was more vulnerable to water damage than lime. Lime plasters had often been applied directly to masonry walls (without lathing), forming a suction bond. They could survive occasional wind -driven moisture or water winking up from the ground. Gypsum plaster needed protection from water. Furring strips had to be used against masonry walls to create a dead air space. This prevented moisture transfer. Many of these traditional plastering tools are still used today. In rehabilitation and restoration projects, Drawing: NPS files. one should rely on the plasterer's judgment about whether to use lime or gypsum plaster. In general, gypsum plaster is the material plasterers use today. Different types of aggregate may be specified by the architect such as clean river sand, perlite, pumice, or vermiculite; however, if historic finishes and textures are being replicated, sand should be used as the base -coat http://www2.cr.nps.gov/tps/briefs/brief2l.htm 3/30/2003 -� Preservation Brief 21: Repairing Historic Flat Plaster --Walls and Ceilings Page 4 of 15 aggregate. Today, if fiber is required in a base coat, a special gypsum is available which includes wood fibers. Lime putty, mixed with about 35% gypsum (gauging plaster) to help it harden, is still used as the finish coat. Lath Lath provided a means of holding the plaster in place. Wooden lath was nailed at right angles directly to the structural members of the buildings (the joists and studs), or it was fastened to nonstructural spaced strips known as furring strips. Three types of lath can be found on historic buildings. Wood Lath. Wood lath is usually made up of narrow, thin strips of wood with spaces in between. The plasterer applies a slight pressure to push the wet plaster through the spaces. The plaster slumps down on the inside of the wall, forming plaster "keys." These keys hold the plaster in place. Metal Lath. Metal lath, patented in England in 1797, began to be used in parts of the United States toward the end of the 19th century. The steel making up the metal lath contained many more spaces than wood lath had contained. These spaces increased the number of keys; metal lath was better able to hold plaster than wood lath had been. Rock Lath. A third lath system commonly used was rock lath (also called plaster board or gypsum -board lath). In use as early as 1900, rock lath was made up of compressed gypsum covered by a paper facing. Some rock lath was textured or perforated to provide a key for wet plaster. A special paper with gypsum crystals in it provides the key for rock lath used today; when wet plaster is applied to the surface, a crystalline bond is achieved. Rock lath was the most economical of the three lathing systems. Lathers or carpenters could prepare a room more quickly. By the late 1930s, rock lath was used almost exclusively in residential plastering. Common Plaster Problems When plaster dries, it is a relatively rigid material which should last almost indefinitely. However, there are conditions that cause plaster to crack, effloresce, separate, or become detached from its lath framewor. These include: • Structural Problems • Poor Workmanship • Improper Curing • Moisture Structural Problems Overloading. Stresses within a wall, or acting on the house as a whole, can create stress cracks. Appearing as diagonal lines in a wall, stress cracks usually start at a door or window frame, but they can appear anywhere in the wall, with seemingly random starting points . htti)://www2.cr.nvs.2ov/tos/briefs/brieP-I.htm 3/30/2003 8.

The weight of the roof, the second and third stories, the furniture, and the occupants could impose a heavy burden on beams, joists, and studs. Even when houses were built properly, later remodeling efforts may have cut in a doorway or window without adding a structural beam or "header" across the top of the opening. Occasionally, load -bearing members were simply too small to carry the loads above them. Deflection or wood "creep" (deflection that occurs over time) can create cracks in plaster. - Overloading and structural movement (especially when combined with rotting lath, rusted nails, or poor quality plaster) can cause plaster to detach from the lath. The plaster loses its key. When the mechanical bond with the lath is broken, plaster becomes loose or bowed. If repairs are not made, especially to ceilings, gravity will simply cause chunks of plaster to fall to the floor. Settlement/Vibration. Cracks in walls can also result when houses settle. Houses built on clay soils are especially vulnerable. Many types of clay (such as montmorillonite) are highly expansive. i �1 In the dry season, water evaporates from the clay Stress cracks in plaster over a kitchen particles, causing them to contract. During the rainy door frame can be repaired using fiberglass mesh tape and joint compound. season, the clay swells. Thus, a building can be riding Photo: NPS flies. on an unstable footing. Diagonal cracks running in opposite directions suggest that house settling and soil conditions may be at fault. Similar symptoms occur when there is a nearby source of vibration -blasting, a train line, busy highway, or repeated sonic booms. Lath movement. Horizontal cracks are often caused by lath movement. Because it absorbs moisture from the air, wood lath expands and contracts as humidity rises and falls. This can cause cracks to appear year after year. Cracks can also appear between rock lath panels. A nail holding the edge of a piece of lath may rust or loosen, or structural movement in the wood framing behind the lath may cause a seam to open. Heavy loads in a storage area above a rock -lath ceiling can also cause ceiling cracks. Errors in initial building construction such as improper bracing, poor corner construction, faulty framing of doors and windows, and undersized beams and floor joists eventually "telegraph" through to the plaster surface. Poor Workmanship In addition to problems caused by movement or weakness in the structural framework, plaster durability can be affected by poor materials or workmanship. y Poorly proportioned mix. The proper proportioning and mixing of materials are vital to the quality of the plaster job. A bad mix can cause problems that appear years later in a plaster wall. Until recently, proportions of aggregate and lime were mixed on the job. A plasterer may have skimped on the amount of cementing material (lime or gypsum) because sand was the cheaper material. Over sanding can cause the plaster to weaken or crumble. Plaster made from a poorly proportioned mix may be more difficult to repair. I http://www2.cr.nps.gov/tps/briefs/brief2l.htm 3/30/2003 w.. Preservation Brief 21: Repairing Historic Flat Plaster --Walls and Ceilings Page 6 of 15 Incompatible base coats and finish coats. Use of perlite as an aggregate also presented problems. Perlite is a lightweight aggregate used in the base coat instead of sand. It performs well in cold weather and has a slightly better insulating value. But if a smooth lime finish coat was applied over perlited base coats on wood or rock lath, cracks would appear in the finish coat and the entire job would have to be redone. To prevent this, a plasterer had to add fine silica sand or finely crushed perlite to the finish coat to compensate for the dramatically differing shrinkage rates between the base coat and the finish coat. Improper plaster application. The finish coat is subject to "chip cracking" if it was applied over an excessively dry base coat, or was insufficiently troweled, or if too little gauging plaster was used. Chip cracking looks very much like an alligatored paint surface. Another common problem is called map cracking --fine, irregular cracks that occur when the finish coat has been applied to an over sanded base coat or a very thin base coat. Too much retardant. Retarding agents are added to slow down the rate at which plaster sets, and thus inhibit hardening. They have traditionally included ammonia, glue, gelatin, starch, molasses, or vegetable oil. If the plasterer has used too much retardant, however, a gypsum plaster will not set within a normal 20 to 30 minute time period. As a result, t!---e surface becomes soft and powdery. delaminated from the brown coat underneath. Photo: Marylee MacDonald. Inadequate plaster thickness. Plaster is applied in three coats over wood lath and metal lath --the scratch, brown, and finish coats. In three -coat work, the scratch coat and brown coat were sometimes applied on successive days to make up the required wall thickness. Using rock lath allowed the plasterer to apply one base coat and the finish coat --a two -coat job. If a plasterer skimped on materials, the wall may not have sufficient plaster thickness to withstand the normal stresses within a building. The minimum total thickness for plaster on gypsum board (rock lath) is 1/2 inch. On metal lath the minimum thickness is 5/8 inch; and for wood lath it is about 3/4 to 7/8 inch. This minimum plaster thickness may affect the thickness of trim projecting from the wall's plane. Improper Curing Proper temperature and air circulation during curing are key factors in a durable plaster job. The ideal temperature for plaster to cure is between 55 to 70 degrees Fahrenheit. However, historic houses were sometimes plastered before window sashes were put in. There was no way to control temperature and humidity. Dry outs, freezing, and sweat -outs. When temperatures were too hot, the plaster would return to its original condition before it was mixed with water, that is, calcined gypsum. A plasterer would have to spray the wall with alum water to reset the plaster. If freezing occurred before the plaster had set, the job would simply have to be redone. If the windows were shut so that air could not circulate, the plaster was subject to sweat -out or rot. Since there is no cure for rotted plaster, the affected area had to be removed and replastered. http://www2.cr.nps.gov/tps/briefs/brief2l.htm 3/30/2003 Preservation Brief 21: Repairing Historic Flat Plaster --Walls and Ceilings Page 7 of 15 Y ; Moisture — Plaster applied to a masonry wall is vulnerable to water damage if the wall is constantly wet. When salts from the masonry substrate come in contact with water, they migrate to the surface of the plaster, appearing as dry bubbles or efflorescence. The source of the moisture must be eliminated before replastering the damaged area. Sources of Water Damage. Moisture problems occur for several reasons. Interior plumbing leaks in older houses are common. Roofs may leak, causing ceiling damage. Gutters and downspouts may also leak, pouring rain water next to the building foundation. In brick buildings, dampness at the foundation level can wick up into the above -grade walls. Another common source of moisture is splashback. When there is a paved area next to a masonry building, rainwater splashing up from the paving can dampen masonry walls. In both cases water travels through the masonry and damages interior plaster. Coatings applied to the interior are not effective over the long run. The moisture problem must be stopped on the outside of the wall. Repairing Historic Plaster Many of the problems described above may not be easy to remedy. If major structural problems are found to be the source of the plaster problem, the structural problem — should be corrected. Some repairs can be made by removing only small sections of plaster to gain access. Minor structural problems that will not endanger the building can generally be ignored. Cosmetic damages from minor building movement, holes, or -- bowed areas can be repaired without the need for wholesale demolition. However, it y may be necessary to remove deteriorated plaster caused by rising damp in order for masonry walls to dry out. Repairs made to a wet base will fail again. _ Canvassing Uneven Wall Surfaces Uneven wall surfaces, caused by previous patching or by partial wallpaper removal, are common in old houses. As long as the plaster is generally sound, cosmetically unattractive plaster walls can be "wallpapered" with strips of a canvas or fabric -like material. Historically, canvassing covered imperfections in the plaster and provided a stable base for decorative painting or wallpaper. Filling Cracks Hairline cracks in wall and ceiling plaster are not a serious cause for concern as long as the underlying plaster is in good condition. They may be filled easily with a patching material. For cracks that reopen with seasonal humidity change, a slightly different method is used. First the crack is widened slightly with a sharp, pointed tool such as a -- crack widener or a triangular can opener. Then the crack is filled. For more persistent y cracks, it may be necessary to bridge the crack with tape. In this instance, a fiberglass mesh tape is pressed into the patching material. After the first application of a quick setting joint compound dries, a second coat is used to cover the tape, feathering it at the edges. A third coat is applied to even out the _. surface, followed by light sanding. The area is cleaned off with a damp sponge, then dried to remove any leftover plaster residue or dust. http://www2.cr.nps.gov/tps/briefs/brief2l.htm 3/30/2003 Preservation Brief 21: Repairing Historic Flat Plaster --Walls and Ceilings Page 8 of 15 When cracks are larger and due to structural movement, repairs need to be made to the structural system before repairing the plaster. Then, the plaster on each side of the crack should be removed to a width of about 6 inches down to the lath. The debris is cleaned out, and metal lath applied to the cleared area, leaving the existing wood lath in place. The metal lath usually prevents further cracking. The crack is patched with an appropriate plaster in three layers (i.e., base coats and finish coat). If a crack seems to be expanding, a structural engineer should be consulted. Replacing Delaminated Areas of the Finish Coat Sometimes the finish coat of plaster comes loose from the base coat. In making this type of repair, the plasterer paints a liquid plaster -bonding agent onto the areas of base -coat plaster that will be replastered with a new lime finish coat. A homeowner wishing to repair small areas of delaminated finish coat can use the methods described in "Patching Materials." Patching Holes in Walls 1790s, the original plaster was asingle coat of lime, sand, and horsehair applied over split lath. A one -coat repair, in this case, is appropriate. For small holes (less than 4 inches in diameter) Photo: John Leeke. that involve loss of the brown and finish coats, the repair is made in two applications. First, a layer of base coat plaster is troweled in place and scraped back below the level of the existing plaster. When the base coat has set but not dried, more plaster is applied to create a smooth, level surface. One -coat patching is not generally recommended by plasterers because it tends to produce concave surfaces that show up when the work is painted. Of course, if the lath only had one coat of plaster originally, then a one -coat patch is appropriate. For larger holes where all three coats of plaster are damaged or missing down to the wood lath, plasterers generally proceed along these lines. First, all the old plaster is cleaned out and any loose lath is re -nailed. Next, a water mist is sprayed on the old lath to keep it from twisting when the new, wet plaster is applied, or better still, a bonding agent is used. To provide more reliable keying and to strengthen the patch, expanded metal lath (diamond mesh) should be attached to the wood lath with tie wires 4 r or nailed over the wood lath with lath nails. The Flat -head wood screws and plaster washers taster is then applied in three layers over the were used to reattach loose k Is plaster to p pp y the wood lath. After the crack Is covered with metal lath, lapping each new layer of plaster over fiberglass mesh tape, all will be skim -coated the old plaster so that old and new are evenly Curtis.with a Patching compound. Photo: John Obed joined. This stepping is recommended to produce a strong, invisible patch. Also, if a patch is made in a plaster wall that is slightly wavy, the contour of the patch should be made to conform to the irregularities of the existing work. A flat patch will stand out from the rest of the wall. Patching Holes in Ceilings http://www2.cr.nps.gov/tps/brie fs/brief21.htm 3/30/2003 Preservation Brief 21: Repairing Historic Flat Plaster --Walls and Ceilings Page 9 of 15 _ Hairline cracks and holes may be unsightly, but when portions of the ceiling come loose, a more Serious problem exists. The keys holding the plaster to the ceiling have probably broken. First, the plaster around the loose plaster should be examined. Keys may have deteriorated because of a localized moisture problem, poor quality _ plaster, or structural overloading; yet, the surrounding system may be intact. If the 1 areas surrounding the loose area are in reasonably good condition, the loose plaster can be reattached to the lath using flathead wood screws and plaster washers. To patch a hole in the ceiling plaster, metal lath is fastened over the wood lath; then the hole is — filled with successive layers of plaster, as described above. Establishing New Plaster Keys ; If the back of the ceiling lath is accessible (usually from the attic or after removing floor boards), small areas of bowed -out plaster can be pushed back against the lath. A padded piece of plywood and braces are used to secure the loose plaster. After dampening the old lath and coating the damaged area with a bonding agent, a fairly liquid plaster mix (with a glue size retardant added) is applied to the backs of the lath, and worked into the voids between the faces of the lath and the back of the plaster. While this first layer is still damp, plaster -soaked strips of jute scrim are laid across the backs of the lath and pressed firmly into the first layer as reinforcement. The original lath must be secure, otherwise the weight of the patching plaster may loosen it. Loose, damaged plaster can also be re -keyed when the goal is to conserve decorative surfaces or wallpaper. Large areas of ceilings and walls can be saved. This method requires the assistance of a skilled conservator --it is not a repair technique used by most plasterers. The conservator injects an acrylic adhesive mixture through holes drilled in the face of the plaster (or through the lath from behind, when accessible). The loose plaster is held firm with plywood bracing until the adhesive bonding mixture sets. When complete, gaps — between the plaster and lath are filled, and the loose plaster is secure. When ceiling repairs are made with wet plaster or with an injected adhesive mixture, the old loose plaster must be supported with a plywood brace until re -keying is complete. Photo: John Leeke. Replastering Over the Old Ceiling If a historic ceiling is too cracked to patch or is sagging (but not damaged from moisture), — plasterers routinely keep the old ceiling and simply relath and replaster over it. This repair technique can be used if lowering the ceiling slightly does not — affect other ornamental features. The existing ceiling is covered with 1x3-inch wood furring strips, one to each joist, and fastened completely through the old lath and plaster using a screw gun. `- Expanded metal lath or gypsum board lath is nailed over the furring strips. Finally, two or three coats are applied according to traditional methods. Replastering over the old ceiling saves time, creates much less dust than demolition, and gives - added fire protection. http://www2.cr.nps.gov/tps/briefs/brief2I htrn 3/30/2003 - rreservatton tsnet zl: Kepairing riistonc rlat Plastcr--Walls and (_;eilings Page to of 1:) When Damaged Plaster Cannot be Repaired --Replacement Options Partial or complete removal may be necessary if plaster is badly damaged, particularly if the damage was caused by long-term moisture problems. Workers undertaking demolition should wear OSHA -approved masks because the plaster dust that flies into the air may contain decades of coal soot. Lead, from lead based paint, is another danger. Long-sleeved clothing and head -and -eye protection should be worn. Asbestos, used in the mid -twentieth century as an insulating and fireproofing additive, may also be present and OSHA -recommended precautions should be taken. If plaster in adjacent rooms is still in good condition, walls should not be pounded --a small trowel or pry bar is worked behind the plaster carefully in order to pry loose pieces off the wall. When the damaged plaster has been removed, the owner must decide whether to replaster over the existing lath or use a different system. This decision should be based in part on the thickness of the original plaster and the condition of the original lath. Economy and time are also valid considerations. It is important to ensure that the wood trim around the windows and doors will have the same "reveal" as before. (The "reveal" is the projection of the wood trim from the surface of the plastered wall). A lath and plaster system that will give this required depth should be selected. Replastering--Alternative Lath Systems for New Plaster Replastering old wood lath. When plasterers work with old lath, each lath strip is re - nailed and the chunks of old plaster are cleaned out. Because the old lath is dry, it must be thoroughly soaked before applying the base coats of plaster, or it will warp and buckle; furthermore, because the water is drawn out, the plaster will fail to set properly. As noted earlier, if new metal lath is installed over old wood lath as the base for new plaster, many of these problems can be avoided and the historic lath can be retained. The ceiling should still be sprayed unless a vapor barrier is placed behind the metal lath. Replastering over new metal lath. An alternative to reusing the old wood lath is to install a different lathing system. Galvanized metal lath is the most expensive, but also the most reliable in terms of longevity, stability, and proper keying. When lathing over open joists, the plasterer should cover the joists with kraft paper or a polyethylene vapor barrier. Three coats of wet plaster are applied consecutively to form a solid, monolithic unit with the lath. The scratch coat keys into the metal lath; the second, or brown, coat bonds to the scratch coat and builds the thickness; the third, or finish coat, consists of lime putty and gauging plaster. Replastering over new rock lath. It is also possible to use rock lath as a plaster base. Plasterers may need to remove the existing wood lath to maintain the woodwork's reveal. Rock lath is a 16x36-inch, 1/2-inch thick, gypsum -core panel covered with absorbent paper with gypsum crystals in the paper. The crystals in the paper bond the wet plaster and anchor it securely. This type of lath requires two coats of new plaster --the brown coat and the finish coat. The gypsum lath itself takes the place of the first, or scratch, coat of plaster. Painting New Plaster http://www2.cr.nps.gov/tpsibriefs/brief2l .htm 3/30/2003 Preservation Brief 21: Repairing Historic Flat Plaster --Walls and Ceilings Page 11 of 15 I The key to a successful paint job is proper drying of the plaster. Historically, lime plasters were allowed to cure for at least a year before the walls were painted or papered. With modern ventilation, plaster cures in a shorter time; however, fresh gypsum plaster with a lime finish coat should still be perfectly dry before paint is applied --or the paint may peel. (Plasterers traditionally used the "match test" on new plaster. If a match would light by striking it on the new plaster surface, the plaster was considered dry.) Today it is best to allow new plaster to cure two to three weeks. A good alkaline - resistant primer, specifically formulated for new plaster, should then be used. A compatible latex or oil -based paint can be used for the final coat. ❑x repair with metal lath, base coats, and finish coat Repairs are being made to the historic plaster. Expanded metal lath is cut to fit A Modern Replacement System the hole, then attached to the wood lath with a tie -wire. Two ready -mix gypsum coats are applied, then a smooth-trowled Veneer Plaster. Using one of the traditional lath and coat of gauged lime. Photo: Walter plaster systems provides the highest quality plaster job. Jowan. However, in some cases, budget and time considerations may lead the owner to consider a less expensive replacement alternative. Designed to reduce the cost of materials, a more recent lath and plaster system is less expensive than a two -or -three coat plaster job, but only slightly more expensive than drywall. This plaster system is called veneer plaster. The system uses gypsum -core panels that are the same size as drywall (4x8 feet), and specially made for veneer plaster. They can be installed over furring channels to masonry walls or over old wood lath walls and ceilings. Known most commonly as "blue board," the panels are covered with a special paper compatible with veneer plaster. Joints between the 4-foot wide sheets are taped with fiberglass mesh, which is bedded in the veneer plaster. After the tape is bedded, a thin, 1/16-inch coat of high -strength veneer plaster is applied to the entire wall surface. A second veneer layer can be used as the "finish" coat, or the veneer plaster can be covered with a gauged lime finish -coat- -the same coat that covers ordinary plaster. Although extremely thin, a two -coat veneer plaster system has a 1,500 psi rating and is thus able to withstand structural movements in a building or surface abrasion. With either a veneer finish or a gauged lime putty finish coat, the room will be ready for painting almost immediately. When complete, the troweled or textured wall surface looks more like traditional plaster than drywall. The thin profile of the veneer system has an added benefit, especially for owners of uninsulated masonry buildings. Insulation can be installed between the pieces of furring channel used to attach blue board to masonry walls. This can be done without having to fur out the window and door jambs. The insulation plus the veneer system will result in the same thickness as the original plaster. Occupants in the rooms will be more comfortable because they will not be losing heat to cold wall surfaces. Patching Materials Plasterers generally use ready -mix base -coat plaster for patching, especially where large holes need to be filled. The ready -mix plaster contains gypsum and aggregate in proper http://www2.cr.nps.gov/tpsibriefs/brief2 l . htm 3/30/2003 Preservation Brief 21: Repairing Historic Flat Plaster --Walls and Ceilings Page 12 of 15 proportions. The plasterer only needs to add water. Another mix plasterers use to patch cracks or small holes, or for finish -coat repair, is a "high gauge" lime putty (50 percent lime; 50 percent gauging plaster). This material will produce a white, smooth patch. It is especially suitable for surface repairs. Although property owners cannot duplicate the years of accumulated knowledge and craft skills of a professional plasterer, there are materials that can be used for do-it- yourself repairs. For example, fine cracks can be filled with an all-purpose drywall joint compound. For bridging larger cracks using fiberglass tape, a homeowner can use a "quicksetting" joint compound. This compound has a fast drying time--60, 90, or 120 minutes. Quick -setting joint compound dries because of a chemical reaction, not because of water evaporation. It shrinks less than all-purpose joint compound and has much the same workability as ready -mix base -coat plaster. However, because quick -set joint compounds are hard to sand, they should only be used to bed tape or to fill large holes. All-purpose point compound should be used as the final coat prior to sanding. Homeowners may also want to try using a ready -mix perlited base -coat plaster for scratch and brown coat repair. The plaster can be hand -mixed in small quantities, but bagged ready -mix should be protected from ambient moisture. A "millmixed pre - gauged" lime finish coat plaster can also be used by homeowners. A base coat utilizing perlite or other lightweight aggregates should only be used for making small repairs (less than 4 ft. patches). For large-scale repairs and entire room replastering, see the precautions in Table 1 for using perlite. Homeowners may see a material sold as "patching plaster" or "plaster of Paris" in hardware stores. This dry powder cannot be used by itself for plaster repairs. It must be combined with lime to create a successful patching mixture. When using a lime finish coat for any repair, wait longer to paint, or use an alkaline - resistant primer. Summary The National Park Service recommends retaining historic plaster if at all possible. Plaster is a significant part of the "fabric" of the building. Much of the building's history is documented in the layers of paint and paper found covering old plaster. For buildings with decorative painting, conservation of historic flat plaster is even more important. Consultation with the National Park Service, with State Historic Preservation Officers, local preservation organizations, historic preservation consultants, or with the Association for Preservation Technology is recommended. Where plaster cannot be repaired or conserved using one of the approaches outlined in this Brief, documentation of the layers of wallpaper and paint should be undertaken before removing the historic plaster. This information may be needed to complete a restoration plan. Plaster Terms Scratch coat. The first base coat put on wood or metal lath. The wet plaster is "scratched" with a scarifier or comb to provide a rough surface so the next layer of base http://www2.cr.nps.gov/tpsibriefsA)rief2 I.htm 3/30/2003 Preservation Brief 21: Repairing Historic Flat Plaster --Walls and Ceilings Page 13 of 15 — coat will stick to it. + Brown coat. The brown coat is the second application of wet, base -coat plaster with wood lath or metal systems. With gypsum board lath (rock lath, plasterboard), it is the only base coat needed. Finish coat. Pure lime, mixed with about 35 percent gauging plaster to help it harden, i is used for the very thin surface finish of the plaster wall. Fine sand can be added for a sanded finish coat. Casing Bead. Early casing bead was made of wood. In the 19th century, metal casing beads were sometimes used around fireplace projections, and door and window openings. Like a wood ground, they indicate the proper thickness for the plaster. Corner Bead. Wire mesh with a rigid metal spline used on Outside corners. Installing the corner bead plumb is important. ' Cornerite. Wire mesh used on inside corners of adjoining walls and ceilings. It keeps — corners from cracking. Ground. Plasterers use metal or wood strips around the edges of doors and windows — and at the bottom of walls. These grounds help keep the plaster the same thickness and provide a stopping edge for the plaster. Early plaster work, however, did not use grounds. On early buildings, the woodwork was installed and primed before plastering began. Some time in ,the early 19th century, a transition occurred, and plasterers applied their wall finish before woodwork was installed. Gypsum. Once mined from large gypsum quarries near Paris (thus the name plaster of — Paris), gypsum in its natural form is calcium sulfate. When calcined (or heated), one - and -a -half water molecules are driven off, leaving a hemi-hydrate of calcium sulfate. When mixed with water, it becomes calcium sulfate again. While gypsum was used in base -coat plaster from the 1890s on, it has always been used in finish coat and decorative plaster. For finish coats, gauging plaster was added to lime putty; it causes the lime to harden. Gypsum is also the ingredient in moulding plaster, a finer plaster used to create decorative moldings in ornamental plaster work. Lime. Found in limestone formations or shell mounds, naturally occurring lime is calcium carbonate. When heated, it becomes calcium oxide. After water has been added, it becomes calcium hydroxide. This calcium hydroxide reacts with carbon dioxide in the air to recreate the original calcium carbonate. Screed. Screeds are strips of plaster run vertically or horizontally on walls or ceilings. They are used to plumb and straighten uneven walls and level ceilings. Metal screeds are used to separate different types of plaster finishes or to separate lime and cement ., plasters.

A log building is defined as a building whose structural walls are composed of horizontally laid or vertically positioned logs. While this Brief will focus upon horizontally -laid, corner -notched log construction, and, in particular, houses as a building type, the basic approach to preservation presented here, as well as many of the physical treatments, can be applied to virtually any kind of log structure. Log buildings, because of their distinct material, physical structure, and sometimes their architectural design, can develop their own unique deterioration problems. The information presented here is intended to convey the range of appropriate preservation techniques available. It does not, however, detail how to perform these treatments; this work should be left to professionals experienced in the preservation of historic log buildings. Rustic log structures were a popular choice for Despite the publication since the 1930s of a vacation cabins In the 20th century.

Log cabins were not the first type of shelter built by all American colonists. The term "log cabin" today is often loosely applied to any type of log house, regardless of its form and the historic context of its setting. "Log cabin" or "log house" often conjures up associations with colonial American history and rough frontier life. While unaltered colonial era buildings in general are rare, historic log buildings as a group are neither as old nor as rare as generally believed. One and two- story log houses were built in towns and settlements across the country until about the middle of the 19th century, and in many areas, particularly in the West, as well as the http://www2.cr.nps.gov/tps/briefs/br-ief26.htm 3/30/2003 Preservation Brief 26: The Preservation and Repair of Historic Log Buildings Page 2 of 18 1 Midwest and southern mountain regions, log continued to be a basic building material despite the introduction of wooden balloon frame construction. By the early 20th century, the popularity of "rustic" architecture had revived log construction throughout the country, and in many areas where it had not been used for decades. A distinction should be drawn between the traditional meanings of "log cabin" and "log house." "Log cabin" generally denotes a simple one, or one -and -one-half story structure, somewhat impermanent, and less finished or less architecturally sophisticated. A "log cabin" was usually constructed with round rather than hewn, or hand -worked, logs, and it was the first generation homestead erected quickly for frontier shelter. "Log house" historically denotes a more permanent, hewn -log dwelling, either one or two stories, of more complex design, often built as a second generation replacement. Many of the earliest 18th and early 19th century log houses were traditionally clad, sooner or later, with wood siding or stucco. Historical Background Unlike western log cabins, 18th and 19th century log houses in the eastern part of the V.S. were almost always covered with siding or stucco. Photo: NPS files. No other architectural form has so captured the imagination of the American people than the tog cabin. Political supporters of 1840 presidential candidate William Henry Harrison appropriated the log cabin as a campaign symbol. The log cabin was birthplace and home for young Abe Lincoln, as well as other national figures, and assumed by many 19th century historians to be the very first type of house constructed by English colonists. In 1893 Frederick Jackson Turner in his influential paper, "The Significance of the Frontier in American History" suggested that European colonists had adopted this means of shelter from the Indians. More recent 20th century scholarship has demonstrated that horizontal log buildings were not the first form of shelter erected by all colonists in America. Nor was log construction technology invented here, but brought by Northern and Central European colonists. Finnish and Swedish settlers are credited with first introducing horizontal log building in the colony of New Sweden (now Pennsylvania) on the upper shores of Delaware Bay in 1638, who later passed on their tradition of log construction to the Welsh settlers in Pennsylvania. During the 17th and 18th centuries, new waves of Eastern and Central Europeans, including Swiss and Germans, came to America bringing their knowledge of log construction. Even the Scotch -Irish, who did not possess a log building tradition of their own, adapted the form of the stone houses of their native country to log construction, and contributed to spreading it across the frontier. In the Mississippi Valley, Colonial French fur traders and settlers had introduced vertical log construction in the 17th century. Through the late 18th and early 19th centuries, frontier settlers erected log cabins as they cleared land, winding their way south in and along the Appalachian valleys through the back country areas of Maryland, Virginia, the Carolinas and Georgia. They moved westward across the Appalachian http://www2.cr.nps.gov/tps/briefs/brief26.htm 3/30/2003 N k . Preservation Brief 26: The Preservation and Repair of Historic Log Buildings Page 3 of 18 Mountain barrier into the Ohio and Mississippi River valleys transporting their indispensable logcraft with them, into Kentucky and Tennessee, and as far to the southwest as eastern Texas. Log buildings are known to have been constructed as temporary shelters by soldiers during the Revolutionary War, and across the country, Americans used logs not only to build houses, but also commercial structures, schools, churches, gristmills, barns, corncribs and a variety of outbuildings. This lodge constructed of logs in the 1880s is an example of the Adirondack style of rustic camp architecture. Photo: NPS riles. Around the mid-19th century, successive generations of fur traders, metal prospectors, and settlers that included farmers and ranchers began to construct log buildings in the Rocky Mountains, the Northwest, California, and Alaska. In California and Alaska, Americans encountered log buildings that had been erected by Russian traders and colonists in the late 18th and early 19th centuries. Scandinavian and Finnish immigrants who settled in the Upper Midwest later in the 19th century also brought their own log building techniques with them. And, many log structures in the Southwest, particularly in New Mexico, show Hispanic influences of its early settlers. n the While many parts of the country never stopped buildingThe gabeendi edoorce19thcntered century gable end in this Tate-19th century log with logs, wooden balloon frame construction had made it building is a typical feature of the obsolete in some of the more populous parts of the Rocky Mountain Cabin style.

In the 1870s, wealthy Americans initiated the Great Camp Movement for rustic vacation retreats in the Adirondack Mountains of upstate New York. Developers such as William Durant, who used natural materials, including wood shingles, stone, and log --often with its bark retained to emphasize the Rustic style --designed comfortable summer houses and lodges that blended with the natural setting. Durant and other creators of the Rustic style drew upon Swiss chalets, traditional Japanese design, and other sources for simple compositions harmonious with nature. Old Faithful Inn, Yellowstone National Park, Wyoming brought the Rustic style to the West in 1903 in an original design, and a scale befitting its setting. Photo: Courtesy, The Adirondack or Rustic style was balanced in the West with construction of the Old Faithful Inn at Yellowstone National Park in Wyoming, designed by Robert C. Reamer, and begun in 1903. This popular resort was tremendously influential in its use of locally -available natural materials, especially log, and gave impetus to Rustic as a true national style. From the turn of the century through the 1920s, Gustav Stickley and other leaders of the Craftsman Movement promoted exposed log construction. During the 1930s and 40s, the Civilian Conservation Corps (CCC) used log construction extensively in many of the country's Federal and State parks to build cabins, lean-tos, visitor centers, and http://www2.cr.nps.gov/tps/briefs/brief26.htm 3/30/2003 _. 1 u.a . . .,i n .. .. .........

Traditional Log Construction Plan and Form When settlers took the craft of log construction with them onto the frontier, they successfully adapted it to regional materials, climates and terrains. One of the most notable characteristics of the earliest 18th and 19th century log houses is the plan and form. The plan can sometimes provide clues to the ethnic origin or route of migration of the original inhabitant or builder. But in the absence of corroborating documentary evidence, it is important not to infer too much about the ethnic craft traditions of a particular log house. Historians have identified a number of traditional house plans and forms as prototypes. They were often repeated with simple variations. The basic unit of each of these types is the one room enclosure formed by four log walls joined at their corners, called a single "pen" or "crib." The single pen was improved upon by installing interior partitions _ or by adding another log pen. Some variations of historic log house plans include: the typically mid -Atlantic "continental" plan, consisting of a single -pen of three rooms organized around a central hearth; the "saddlebag" or double -pen plan, composed of two contiguous log pens; and the "dogtrot" plan, formed by two pens separated by an -' open passage space (sometimes enclosed later), all covered by a continuous roof. The continental plan originated in central and eastern Europe and is attributed to 18th century German immigrants to Pennsylvania. Non -log interior partition walls form the multi -room plan within the exterior log walls. The saddlebag plan consists of two adjoining log pens that share a central chimney. A saddlebag is often the evolution of a single pen with an end chimney, expanded by adding a second pen onto the chimney endwall. The saddlebag was built in a number of different regions across the country. The dogtrot plan may be seen with variation in many parts of the country, although it is sometimes, perhaps erroneously, considered the most typically southern, because its covered passageway provided both air circulation and shelter from the heat. All these plan types were typically built in the form of one or one -and -one-half story settlement cabins. A somewhat different form evolved in the West around the middle of the 19th century which became especially distinctive of the Rocky Mountain cabin. While the entrance doorway to most earlier log houses was generally placed beneath the eaves, as a -- means of adapting to the greater snowfall in the Rockies, here the entrance was placed in the gable end, and sometimes protected from roof slides by a porch supported by two corner posts created by an extension of the roof beyond the gable wall. _ From the late 18th through the mid-19th centuries, Americans also built many substantial two-story log houses in towns throughout the eastern half of the country. In _ rural areas two-story log houses were sometimes built to replace earlier, first - generation settlement cabins, but just as often the early hewn -log house was retained and enlarged. A second story was added by removing the roof and gables, constructing a second floor, laying additional courses of logs, and building a new roof, or reassembling the old one. Each generation of owners might expand an early log core building by adding on new log pens, or masonry or wood frame extensions. The addition of a rear ell, or infill construction to link a formerly freestanding outbuilding, such as a kitchen to the log main house was particularly common. Such a layering of alterations is part of the evolution of many log buildings. - http://www2.cr.nps.gov/tps/briefs/brief26.htm 3/30/2003 Preservation Brief 26: The Preservation and Repair of Historic Log Buildings Page 5 of 18 Corner Notching and Other Fastening Techniques Corner notching is another of the characteristic features of log construction. Most notching methods provide structural integrity, by locking the log ends in place, and give the pen rigidity and stability. Like the floor plan, the type of corner notching can sometimes be a clue to the ethnic craft origin of a log building, but it is important not to draw conclusions based only on notching details. Numerous corner notching techniques have been identified throughout the country. They range from the simple "saddle" notching, which demands minimal time and A log to replace the deteriorated sill is being hewn in hewing skill, to the very common "V the traditional manner with a broad axe. Photo: NPS notching or "steeple" notching, to "full files. dovetail" notching, one of the tightest but most time-consuming to accomplish, "half -dovetail" notching which is probably one of the most common, and "square" notching secured with pegs or spikes. The notching method on some of the earliest eastern cabins and most 19th century western cabins, particularly saddle notching, left an extended log end or "crown." Crowns are especially pronounced or exaggerated in Rustic style structures, and sometimes they are cut shorter as the wall rises, creating a buttress effect at the corners of the building. Another method of securing log ends consists of fastening logs that are laid without notching ("false notching") with tenons into vertical corner posts, or using spikes or pegs to attach them to vertical corner planks. Vertically positioned logs were secured at their top and bottom ends, usually into roof and sill plate timbers. Selecting Logs and Assembling the Building Although wood selection was most likely to be determined by availability, chestnut, white oak, cedar, and fir were preferred because these trees could provide long, straight, rot -resistant logs. Pine, which also provided long straight logs, was also used in areas where it was plentiful. Woods were often mixed, utilizing harder, heavier rot - resistant wood such as white oak for the foundation,"sill log", and lighter, more easily hewn wood such as yellow poplar for the upper log courses. One of the principal advantages of log construction was the economy of tools required to complete a structure. A felling axe was the traditional tool for bringing down the tree and cutting the logs to length. For many frontier and western structures the round logs were debarked or used in their original form with the bark left on, or one or more sides of the logs were hewn flat with a broadaxe, or more finely finished with an adze as smooth thick planks. Notching was done with an axe, hatchet or saw; openings for doors and windows were usually cut after the logs were set into place, and door and window frames, particularly jambs, were put in place during construction to help hold the logs in place. Roof framing members and floor joists were either hewn from logs or of milled lumber. A log cabin could be raised and largely completed with as few as two to four different tools, including a felling axe, a broad axe, and a hand saw or crosscut saw. http://www2.cr.nps.gov/tps/briefs/brief26.htm 3/30/2003 Preservation Brief 26: The Preservation and Repair of Historic Log Buildings Page 6 of 18 z _ e The upper gable walls were completed with logs if the roof was constructed with purlins, — which is more typical of Scandinavian or Finnish construction, and western and 20th century Rustic styles. However, vertical or horizontal weatherboard sheathing was commonly used throughout the country to cover wood -framed gables. _ 115 Chinking and Daubing The horizontal spaces or joints between logs are usually filled with a combination of materials that together is known as "chinking" and "daubing." Chinking and daubing completed the exterior walls of the log pen by sealing them against driving wind and snow, helping them to shed rain, and blocking r the entry of vermin. In addition, chinking and cry r daubing could compensate for a minimal amount of hewing and save time if immediate shelter was needed. Not all types of log buildings were chinked. Stone or wood strips served to fill in the Corncribs, and sometimes portions of barns where chinking areas over which the daubing was applied. Photo: NPS files. ventilation was needed were not chinked. While more typical of Swedish or Finnish techniques, and not as common in American log construction, tight -fitting plank -hewn or scribed -fit round logs have little or no need for chinking and daubing. A variety of materials were used for chinking and daubing, including whatever was most conveniently at hand. Generally though, it is a three-part system applied in several steps. The chinking consists of two parts: first, a dry, bulky, rigid blocking, such as wood slabs or stones is inserted into the joint, followed by a soft packing filler such as oakum, moss, clay, or dried animal dung. Daubing, which completes the system, is the outer wet -troweled finish layer of varying composition, but often consisting of a mixture of clay and lime or other locally available materials. Instead of daubing, carefully fitted quarter poles or narrow wood strips were sometimes nailed lengthwise across the log joints. Chinking, especially the daubing, is the least durable part of a log building. It is susceptible to cracking as a result of freeze -thaw action, structural settlement, drying of the logs, and a thermal expansion -contraction rate that differs from that of the logs. _ Seasonal deterioration of chinking necessitates continual inspection and regular patching or replacement. Exterior Wall Treatments Although the exterior logs of cabins in the West, and 20th century Rustic buildings are generally not covered, many 18th and 19th century log houses east of the Mississippi, — with the exception of some of the simpler cabins and houses in remote or poorer areas, were covered with exterior cladding. The exterior of the log walls was covered for both aesthetic and practical reasons either as soon as the building was completed or sometime later. j In some instances, the exterior (and interior) of the logs was whitewashed. This served to discourage insects, and sealed hairline cracks in the daubing and fissures between the daubing and logs. Although the solubility of whitewash allows it to heal some of its own hairline cracks with the wash http://www2.cr.nps.gov/tpsibriefs/brief26.htm 3/30/2003 "" p. , rreservation 13net 26: the Preservation and Repair of Historic Log Buildings Page '/ of IS of rain, like daubing it has to be periodically reapplied. Usually, a more permanent covering such as wood siding or stucco was applied to the walls, which provided better insulation and protection, and reduced the maintenance of the log walls. Sometimes log houses were sided or stuccoed later in an attempt to express a newly -achieved financial or social status. Many log houses were immediately sided and trimmed upon completion to disguise their simple construction beneath Georgian, Federal and later architectural styles. Frequently a log house was covered, or recovered, when a new addition was erected in order to harmonize the whole, especially if the original core and its addition were constructed of different materials such as log and wood frame. Once the siding is gone, the logs may rapidly deteriorate unless another protective treatment is applied. Photo: NPS files. Vertical wood furring strips were generally nailed to the logs prior to applying weatherboarding or stucco. This ensured that the walls would be plumb, and provided a base on which to attach the clapboards, or on which to nail the wood lath for stucco. Foundations Log building foundations varied considerably in quality, material, and configuration. In many cases, the foundation consisted of a continuous course of flat stones (with or without mortar), several piers consisting of rubblestone, single stones, brick, short vertical log pilings, or horizontal log "sleepers" set on grade. The two "sill logs," were laid directly upon one of these types of foundations. Climate and intended permanence of the structure were the primary factors affecting foundation construction. The earliest log cabins, and temporary log dwellings in general, were the most likely to be constructed on log pilings or log sleepers set directly on grade. Where a more permanent log dwelling was intended, or where a warm, humid climate accelerated wood decay, such as in the South, it was sometimes more common to use stone piers which allowed air to circulate beneath the sill logs. Full cellars were not generally included in the original construction of most of the earliest log houses, but root cellars were often dug later. Roofs Log buildings were roofed with a variety of different framing systems and covering materials. Like log house plans and corner notching styles, the types of roof framing systems used were often variations on particular ethnic and regional carpentry traditions. In most cases wood shingles were the first roof covering used on the earliest 18th and 19th century log houses. As wood shingle roofs deteriorated, many were replaced with standing seam metal roofs, many of which continue to provide good service today. Later pioneer log buildings west of the Mississippi were likely to be roofed with metal or roll roofing, or even with sod. Other log buildings have been re -roofed in the 20th century with asphalt shingles. For some rustic log buildings in the West and Great Camps in the Adirondacks, asphalt shingles are the original historic roofing material. Chimneys http://www2.cr.nps.gov/tps/briefs/brief26.htm 3/30/2003 Preservation Brief 26: The Preservation and Repair of Historic Log Buiidings rage 6 of i is — Ethnic tradition and regional adaptation also influenced chimney construction and placement. Chimneys in loghouses were usually built of stone or brick, a combination of the two, or even -clay -lined, notched logs or smaller sticks. Later log buildings were frequently constructed with only metal stacks to accommodate wood stoves. The — chimneys of log buildings erected in cold climates tended to be located entirely inside the house to maximize heat retention. In the South, where winters were less severe the chimney stack was more typically constructed outside the log walls. With the advent of more efficient heating systems, interior chimneys were frequently demolished or relocated and rebuilt to maximize interior space. Interior Finishes Logs on the interiors of many of the simpler cabins and Rustic style structures were often given a flattened surface or left exposed. But, in the more finished log houses of the 18th and 19th century, they were more commonly covered for most of the same reasons that the exterior of the logs was covered --improved insulation, ease of maintenance, aesthetics, and keeping out vermin. Covering the interior log walls with 7 planks, lath and plaster, boards pasted with newspaper, fabric such as muslin, or wallpaper increased their resistance to air infiltration and their insulation value. Finished walls could be cleaned and painted more easily, and plastered walls and ceilings obscured the rough log construction and prepared interior surfaces for decorative wood trim in the current styles. Historical Evaluation and Damage Assessment Before undertaking preservation work on a historic log building, its history and design should be investigated, and physical condition evaluated. It is always advisable to hire a historical architect or qualified professional experienced in preservation work to supervise the project. In addition, State Historic Preservation Offices, regional offices of _ the National Park Service, and local historical commissions may also provide technical and procedural advice. The historical investigation should be carried out in conjunction with a visual inspection of the log building. Physical assessment needs to be systematic and thorough. It should include taking notes, photographs or video recording, and making drawings of existing conditions, including overall and detail views. This will serve as a record of the appearance and condition which can be referred to once work is under way. A physical assessment should also identify causes of deterioration, not just symptoms or manifestations and, in some instances, may need to include a structural investigation. — Foundation Inspection The foundation of a log building should always be inspected before beginning work because, as in any building, foundation -related problems can transfer structural defects to other components of the building. Settling of the foundation is a typical condition of _ log buildings. If settlement is not severe and is no longer active, it is not necessarily a problem. If, however, settlement is active or uneven, if it is shifting structural weight to unintended bearing points away from the intended main bearing points of the corner _ notches and sill log, serious wall deflections may have resulted. Causes of settlement may include foundation or chimney stones or sill logs that have sunk into the ground, decay of log pilings, log sleepers, or of the sill logs themselves. _ Log Inspection - http://www2.cr.nps.gov/tpsibriefs/brief26.htm 3/30/2003 Preservation Brief 26: The Preservation and Repair of Historic Log Buildings Page 9 of 18 Foundation problems usually result in damage to the sill logs and spandrels, which are often the most susceptible to deterioration. Sill logs, along with the corner notching, tend to bear most of the weight of the building, and are closest to vegetation and the ground, which harbors wood -destroying moisture and insects. If the sill log has come into contact with the ground, deterioration is probably underway or likely to begin. It is also important to check the drainage around the building. The building assessment should note the condition of each log and attempt to identify the sources of problems that appear to exist. Sill log inspection should not necessitate destruction of historic exterior cladding if it exists. Inspection can usually be made in areas where cladding is missing, loose, or deteriorated. Sill log, as well as upper log, deterioration may also be revealed by loose or peeling areas of the cladding. If pieces of cladding must be removed for log inspection, they should be labeled and saved for reinstallation, or as samples for replacement work. Historic cladding generally need not be disturbed unless there are obvious signs of settling or other indications of deterioration. Other areas of the log walls which are particularly susceptible to deterioration include window and door sills, corner notches, and crowns, and any other areas regularly saturated by rain runoff or backsplash. The characteristic design feature of Adirondack or Rustic style log buildings of leaving log ends or crowns to extend beyond the notched corners of the building positions the crowns beyond the drip -line of the roof edge. This makes them vulnerable to saturation from roof runoff, and a likely spot for deterioration. Saddle notching in which the cut was made out of the top surface of the log and which cups upward, and flat notching, may also be especially susceptible to collecting runoff moisture. Detection of decay requires thorough inspection. Probing for rot should be done carefully since repair techniques can sometimes save even badly deteriorated logs. Soft areas should be probed with a small knife blade or icepick to determine the depth of decay. Logs should be gently tapped at regular intervals up and down their lengths with the tool handle to detect hollow -sounding areas of possible interior decay. Long cracks which run with the wood grain, called "checks," are not signs of rot, but are characteristic features of the seasoning of the logs. However, a check can admit moisture and fungal decay into a log, especially if it is located on the log's upper surface. Checks should also be probed with a tool blade to determine whether decay is underway inside the log. Sill log ground contact and relative moisture content also provide ideal conditions for certain types of insect infestation. Wood building members, such as sill logs or weatherboarding, less than eight inches from th— ground, should be noted as a potential problem for monitoring or correction. Sighting of insects, or their damage, or telltale signs of their activity, such as mud tunnels, exit holes, or "frass," a sawdust -like powder, should be recorded. Insect infestation is best treated by a professionally licensed exterminator, as the chemicals used to kill wood -destroying insects and deter reinfestation are generally toxic. Roof Inspection This rotted sill cannot be repaired and must be replaced. Photo: NPS tiles. Along with the foundation, the roof is the other most vital component of any building. htti)://www2.cr.nDS.2ov/tt)s/hriefsfbrief26.htm 3/30/2003 Sent By: American Family Insurance; 970 229 9087; �n 00'ft<-) Western Surety C BID BOND (mod Amount) .

The roof and gutters should be inspected and checked for leaks both from the exterior, 2 as well as inside if possible. Inspection may reveal evidence of an earlier roof type, or covering, and sometimes remnants of more than one historic covering material. The roof may be the result of a later alteration, or raised when a second story was added, or repaired as the result of storm or fire damage. Often, roof framing may be composed of reused material recycled from earlier buildings. Inspection of the roof framing should note its configuration and condition. Typical problems to look for are framing members that have been dislodged from their sockets in the roof plate, or that are cracked, ridge _ damage, sagging rafters, broken ties and braces, and decay of exterior exposed rafter or purlin ends, especially common on Rustic style buildings. Other Features The rest of the building should also be inspected as part of the overall assessment, including siding, window sash and frames, door frames and leafs, chimneys, porches, and interior walls, trim, and finishes. Any of these features may exhibit deterioration problems, inherent to the material or to a construction detail, or may show the effects of problems transmitted from elsewhere, such as a deformed or mis-shapen window - frame resulting from a failed sill log. The inspection should note alterations and repairs made over time, and identify those modifications which have acquired significance and should be preserved. Nothing should be removed or altered before it has been examined and its historical significance noted. Preservation Treatments Since excessive moisture promotes and hastens both fungal and insect attack, it should be dealt with immediately. Not only must the roof and gutters be repaired --if none ' exist, gutters should probably be added --but the foundation grade should be sloped to ensure drainage away from the building. If the distance from the ground to the sill log or exterior sheathing is less than eight inches, the ground should be graded to achieve _ this minimum distance. Excess vegetation and debris such as firewood, dead leaves, or rubbish should be cleared from the foundation perimeter, and climbing vines whose leaves retain moisture and tendrils erode daubing, should be killed and removed. Moisture problems due to faulty interior plumbing should also be remedied. Solving or reducing moisture problems may in itself end or halt the progress of rot and wood - destroying insects. Log Repair Stabilizing and repairing a log that has been only partially damaged by decay or insects is always preferable to replacing it. Retaining the log, rather than substituting a new one, preserves more of the building's integrity, including historic tool marks and the wood species which may no longer be obtainable in original dimensions. Log repair can generally be done with the log in place at less cost, in less time, and with less damage to building fabric, than by removing, and installing a new hewn and notched replacement log. Log repair is accomplished by two basic methods: traditional methods _ of splicing in new or old wood, or through the use of epoxies. These treatments are sometimes combined, and may also be used in conjunction with reinforcing members. s.M http://www2.cr.nps.gov/tpsibriefs/brief26.htrn 3/30/2003 Preservation Brief 26: The Preservation and Repair of Historic Log Buildings Page 11 of 18 Historic log repair, whether it involves patching techniques or the use of epoxies, should always be performed only by an experienced craftsperson or architectural conservator. Wood Splicing Wood splicing can involve several types of techniques. Also referred to as "piecing -in" or "Dutchman" repair, it involves treating a localized area of deterioration by cutting out the decayed area of the log, and carefully carving and installing a matching, seasoned wood replacement plug or splice. The wood species, if available, and the direction and pattern of the grain should match that of adjacent original wood. The location and depth of decay should determine the splicing technique to be used. In a case where decay runs deep within a log, a full -depth segment containing the affected area can be cut out, severing the log completely, and a new segment of log spliced in, using angled "scarf" joints or square -cut "half -lap" joints. The splice is secured to the severed log by angling lag screws or bolts through the upper and lower surfaces that will be concealed by daubing. Splicing can also be performed using epoxy as an adhesive. A log with shallow decay on its outer face can be cut back to sound depth, and a half -log face spliced on, adhered with epoxy, screws or bolts. A technique for the repair of badly deteriorated log crowns involves cutting them back to sound wood, and into the notching joint if necessary, and installing new crowns cut to match. Fiberglass or aluminum reinforcement rods are inserted into holes drilled into the new crowns, and into corresponding holes drilled in the ends of the original cutoff logs. Epoxy is used as an adhesive to attach and hold the new crowns in place. Long lag screws can be angled up through the underside of the crown into the log above to provide additional support for the repair. Epoxy Consolidation and Repair In some instances, epoxies may be used by themselves to consolidate and fill the voids left by deteriorated wood. Epoxies are versatile in performance, relatively easy to use by experts, and, after curing, may be shaped with woodworking tools. Their use requires that sufficient sound wood survives for the epoxy to adhere. But they can be used to stabilize rotted wood, return full or greater than original strength to decayed structure -bearing members, and to reconstitute the shape of decayed log ends. Epoxies resist decay and insects, and while epoxy itself is resistant to moisture, epoxy tends to cause adjacent wood to retain moisture rather than dry out, and if not used in the right location, can actually further a continuing cycle of wood decay. Hence, epoxy repairs are most successful in areas where they are protected from moisture. Epoxies, of which there are a variety of commercially -available products on the market, are prepared in essentially two forms: a liquid consolidant and a flexible putty filler.Each consists of a resin and a hardener which must be mixed prior to use. The technique of treating, for an example, a decayed log crown with epoxies is begun by removing loose decayed wood, and drying the area if necessary. The rot -affected cavity and surface of the log end is then saturated with liquid epoxy by repeated brushing, or by soaking it in a plastic bag filled with epoxy that is attached to the log. The porous condition of the rot -damaged wood will draw up the epoxy like a lamp wick. Once the liquid epoxy has saturated the log end and cured, the log end has been consolidated, and is ready for the application of an epoxy putty filler. The filler resin and hardener must also be mixed, pigments must be mixed with the filler epoxy to color the patch, and more importantly to protect it from ultraviolet sunlight. The filler can be applied with a putty knife, pressing it into the irregularities of the cavity. The cured patch can be worked like wood and painted with an opaque stain or a dull finish paint to htti)://www2.cr.nps.gov/tDs/briefs/brief26.htm 3/30/2003 Preservation Brief 26: The Preservation and Repair of Historic Log Buildings Page 12 of 18 _ help it blend with surrounding wood, although epoxy repairs can be difficult to disguise on natural, unpainted wood. Epoxies can be used to consolidate and repair other areas of a log, including rotted internal areas which have not yet progressed to damage the log's outer surface. Saturation of small internal areas can be accomplished by drilling several random holes _ into the log through an area that will be concealed by daubing, and then pouring in liquid epoxy. If a pure resin is used, it should be a casting resin to minimize shrinkage, and it is best to fill voids with a resin that contains aggregates such as sand, or micro - balloons. Epoxy is frequently used by architectural conservators to strengthen deteriorated structural members. The damaged log can be strengthened by removing the deteriorated wood, and filling the void by imbedding a reinforcing bar in epoxy filler, making sure the void is properly sealed to contain the epoxy before using it. Sometimes larger decayed internal areas of a log can be more easily accessed and repaired from the interior of a structure. This may be a useful technique if it can be accomplished without causing undue damage to the interior finishes in the log building. However, _ despite its many advantages, epoxy may not be an appropriate treatment for all log repairs, and it should not be used in an attempt to conceal checking, or extensive log surface patching that is exposed to view, or logs that are substantially decayed or collapsed. Log Replacement Repairing or replacing only a segment of a log is not always possible. Replacement of an entire log may be the only solution if it has been substantially lost to decay and collapsed under the weight of logs above it. Log replacement, which should be carried out only by experienced craftspersons, is begun by temporarily supporting the logs above, and then jacking them up just enough to insert the new log. Potential danger to the structure may include creating inadequate temporary bearing points, and crushing _ chinking and interior finishes which may have settled slowly into non -original positions that cannot withstand jacking. The new sill matches the original and is a compatible replacment. Photo: NPS tiles. To begin the process of log replacement, the entire length of the log must be inspected from the exterior and the interior of the structure to determine whether it supports any structural members or features, and how their load can be taken up by bracing during jacking and removal. On the exterior, sheathing such as weatherboard, and adjacent chinking, must be removed along the length of the log to perform this inspection. Likewise, on the interior, abutting partition walls and plaster may also need to be removed around the log to determine what, if any, features are supported by - or tied into the log to be removed. _ A replacement log should be obtained to match the wood species of the original being removed. If it Is a hewn log, then the replacement must be hewn to replicate the dimensions and tool marks of the original. If the same wood species cannot be obtained in the original dimensions, a substitute species may have to be used, and may even be preferable in some instances if a more durable wood can be found than the original wood species. It should, however, be chosen to match the visual characteristics of the original species as closely as possible. http://www2.cr.nps.gov/tps/briefs/brief26.htm 3/30/2003 k ,.. Preservation Brief 26: The Preservation and Repair of Historic Log Buildings Page 13 of 18 Wood Preservatives In most instances, the use of chemical wood preservatives is not generally recommended on historic log buildings. Preservatives tend to change the color or appearance of the logs. In addition, many are toxic, they tend to leach out of the wood over time, and like paint, must be periodically reapplied. Many of the late 19th and early 20th century Rustic structures were constructed of logs with the bark left on which may provide protection, while others have been painted. However, some log buildings, and especially log houses that have been inappropriately stripped of historic cladding in an earlier restoration, and now show signs of weathering, such as deep checking, may be exceptions to this guidance. A preservative treatment may be worth considering in these cases. Boiled linseed oil may sometimes be appropriate to use on selected exposures of a building that are particularly vulnerable to weathering, although linseed oil does tend to darken over time. Borate solutions, which do not alter the color or appearance of wood, may be another of the few effective, nonhazardous preservatives available. However, borate solutions do not penetrate dry wood well, and thus the wood must be green or wet. Because borate solutions are water-soluble, after treating, the wood must be coated with a water-repellent coating. In some instances, it may be appropriate to reapply varnish where it was used as the original finish treatment. Pressure -treating, while effective for new wood, is not applicable to in -place log treatment, and is generally not effective for large timbers and logs because it does not penetrate deeply enough. Foundation Repair The foundation should have good drainage, be stable, adequately support the building as well as any future floorloads, and keep the sill log sufficiently clear of the ground and moisture to deter decay and insect infestation. Log buildings with cellars are less likely to suffer problems than those built upon the ground or with crawl spaces, as long as the cellar is kept dry and ventilated. Because the foundations of many log buildings were neither dug nor laid below the frost -like, they generally tend to be susceptible to freeze - thaw ground heaving and settlement. Also, as previously noted, some foundations consisted of wooden sleepers or pilings in direct contact with the ground. If a foundation problem is minor, such as the need for repointing or resetting a few stones, work should address only those areas. Loose stones should be reset in their original locations if possible. A clearly inadequate foundation that has virtually disappeared into the ground, or where large areas of masonry have buckled or sunk, resulting in excessively uneven or active settlement, will need to be rebuilt using modern construction methods but to match the historic appearance. Chinking Repair Repair of chinking, whether it is finished on the exterior with wooden strips or with daubing, should not be done until all log repair or replacement, structural jacking and shoring is completed, and all replacement logs have seasoned. Historically, patching and replacing daubing on a routine basis was a seasonal chore. This was because environmental factors -- building settlement, seasonal expansion and contraction of logs, and moisture infiltration followed by freeze -thaw action --cracks and loosens daubing. If the exterior log walls are exposed, and the chinking or daubing requires repair, as much of the remaining inner blocking filler and daubing should be retained as possible. A daubing formula and tooled finish that matches the http://www2.cr.nps.gov/tpsibriefs/brief26.htm 3/30/2003 .. _ .. .. Preservation Brief 26: The Preservation and Repair of Historic Log Buildings Page 14 of 18 Daubing composed entirely of Portland cement is never appropriate to use on a hi tod to buildin Photo: historic daubing, if known, should be used, or based on one of the mixes listed here. For the most part, modern commercially - available chinking products are not suitable for use on historic log buildings, although an exception might be on the interior of a log building where it will be covered by plaster or wood, and will not be visible. These products tend to have a sandy appearance that may be compatible with some historic daubing, but the color, and other visual and physical characteristics are generally incompatible with historic log surfaces. Sections of wood chinking which are gone or cannot be made weathertight should be replaced with same -sized species saplings or quarter poles cut to fit. Generally, unless bark was used originally, it should be removed before nailing the new wood chinking replacements tightly into place. Nas files., g Analysis of daubing can be done in much the same way as mortar analysis. If that is not feasible, by crushing a loose piece of daubing its constituent parts can be exposed, which may typically include lime, sand, clay, and, as binders, straw or animal hair. The color imparted by the sand or pigmented constituents should be noted, and any areas of original daubing should be recorded with color film for later reference. Daubing that is loose or is not adhered to the logs must first be cleaned out by hand. Blocking filler should be left intact, refitting only loose pieces. (Sometimes it may be difficult to obtain a good bond in which case it may be necessary to clean out the joint entirely.) If needed, soft filler should be added, such as jute or bits of fiberglass batt, pressed firmly into voids with a stick or blunt tool. Concealed reinforcement may sometimes be used, depending upon the authenticity of the restoration. This can include galvanized nails partially inserted only on the upper side of the log to allow for the daubing to move with the upper log and keep the top joint sealed, or galvanized wire mesh secured with galvanized nails. Like repointing masonry, daubing should not be done in full sun, excessive heat or when freezing temperatures are expected. The daubing materials should be dry -mixed, the chinking rechecked as being tight and secure, and the mix wetted and stirred to a stiff, paste - like consistency. The mix dries quickly, so no more daubing should be prepared at a time than can be applied in about 30 minutes. A test patch of new daubing, either on the building, or in a mockup elsewhere, will help test the suitability of the formula's color and texture match. Before applying the daubing, the chinking area, including filler and log surfaces to be covered, should be sprayed with water to prevent the dry filler from too rapidly drawing off the daubing moisture which will result in hairline cracking. A trowel, ground to the width of the daubing, is used to press the daubing into the chinking space, and to smooth the filled areas. Wide or deep chinking spaces or joints may have to be daubed in layers, to prevent sagging and separation from the logs, by applying one or two scratch coats before finishing the surface. Portland cement was a part of the original daubing used in many late 19th and early 20th century log buildings, and is therefore appropriate to include in repairing buildings of this period. Although a small amount of portland cement may be added to a lime, clay and sand mix for workability, there should not be more than 1 part portland cement to 2 parts of lime in daubing mixes intended for most historic log buildings. Portland cement tends to shrink and develop hairline cracks, and retain moisture, all of which can be potentially damaging to the logs. httn-//www2_cr.nns.eov/tos/briefs/btief26.htm 3/30/2003 *_ Preservation Brief 26: The Preservation and Repair of Historic Log Buildings Page 15 of 18 Daubing Mixes ` MIX A 1 MIX B MIX C parts (volume) material 1/4 cement 1 lime 4 sand 1/8 dry color hog bristles or excelsior 6 sand 4 lime 1 cement 1 portland cement 4-8 lime 7-10 sand Mix A (Donald A.

Interior Treatments There is no single appropriate way to finish or restore the interior of a historic log house. Each building and its history is unique. The temptation should be resisted to impart an unfinished frontier character by removing plaster to expose interior log walls or joists in the ceiling. Instead, interior treatments should be based on existing evidence, and guided by old photographs, written documentation, and interviews with previous owners. Interior features and finishes that might exist in some 18th and 19th century log houses include wood paneled walls, wood moldings, stairs, and fireplace mantels; where they have survived, these features should be retained. Many of the more rustic log buildings built later in the 19th or early 20th century intentionally featured exposed interior log walls, sometimes with the logs peeled and varnished. If interior plaster is severely damaged or has previously been removed, and evidence such as lath ghosting on the logs exists, walls should be replastered or recovered with gypsum board or dry wall to match the historic appearance. Preserving Log Buildings in Their Historic Settings http://v✓�vw2.cr.ni)s.,Rov/tps/briefs/brief26.htm 3/30/2003 Preservation Brief 26: The Preservation and Repair of Historic Log Buildings Page 16 of 18 — K Log buildings are too often viewed as portable resources. Like other historic buildings, moved or relocated log structures can suffer a loss of integrity of materials and of setting. Historic buildings listed in the National Register of Historic Places may be subject to loss of that status if moved. Despite the popularity of dismantling and relocating log buildings, they should be moved only as a last resort, if that is the only way to save them from demolition. If they must be moved, it is preferable that they be moved intact-- that is, in one piece rather than disassembled. Disassembling and moving a log building can result in considerable loss of the historic building materials. While the logs and roof framing members can be numbered for reassembly, dismantling a log building can result in loss of such features as foundation and chimney, chinking and daubing, exterior cladding, and interior finishes. Furthermore, log buildings can rarely be put back together as easily as they were taken apart. Summary Historic log buildings regardless of whether they are of horizontal or vertical ' construction, or whether they are 18th century log houses or early 20th century Rustic style cabins, are unique. Their conservation essentially centers on the preservation and repair of the logs, and appropriate repairs to chinking and daubing, which like — repointing of masonry, is necessary to ensure that most log buildings are weathertight. Log building preservation may be accomplished with a variety of techniques including splicing and piecing -in, the use of epoxy, or a combination of patching and epoxy, and — often, selected replacement. But, like any historic building, a log structure is a system that functions through the maintenance of the totality of its parts. The exterior of many of the earliest late 18th and 19th century log buildings, and particularly those east of the Mississippi, were commonly covered with some type of cladding, either horizontal or vertical wood siding, stucco, or sometimes a combination. If extant, this historic cladding, which may be hidden under a later, non -historic — artificial siding such as aluminum, vinyl, or asbestos, should be preserved and repaired, or replaced if evidence indicates that it existed, as a significant character -defining feature of the building. _ Selected Reading Briscoe, Frank.
