See Contract Documents for additional information. College/Willox Improvement Project Project Special Provisions REVISION OF SECTION 101 DEFINITIONS OF TERMS Technical Specifications related to construction materials and methods for the work embraced under this Contract shall consist of the "Colorado Department of Transportation, State of Colorado, Standard Specifications for Road and Bridge Construction" dated 2005. Certain terms utilized in the Specifications referred to in the paragraph above shall be interpreted to have different meanings within the scope of this Contract. A summary of redefinitions follows: Where reference is made in the plans and specifications to Owner, Department, Chief Engineer, Resident Engineer, Project Engineer, Engineer, and Inspection and Testing Agency it is understood to mean the City of Fort Collins, Colorado or the City's representative. The sections shown on the following pages are revisions to the Technical Specifications for this project. College/Willox Improvement Project Project Special Provisions REVISION OF SECTION 102 PROJECT PLANS AND OTHER DATA Section 102 of the Standard Specifications is hereby revised for this project as follows: Subsection 102.05 shall include the following: Copies of the Contract Documents complete with Construction Specifications and Drawings may be viewed at the following locations until the date set for opening of bids: 1. Online at the City of Fort Collins Buy Speed Webpage, www.fcgov.com/eprocurement After the proposals have been opened, the low responsive, responsible bidder may obtain from the City of Fort Collins at no cost: 10 sets of plans and Special Provisions College/Willox Improvement Project Project Special Provisions REVISION OF SECTION 104 SCOPE OF WORK Section 104 of the Standard Specifications is hereby revised for this project as follows: Subsection 104.02 shall include: Site Conditions A. General: 1. The Contractor acknowledges that he has satisfied himself as to the nature and location of the work, the general and local conditions, particularly those bearing upon access to the site; handling, storage, and disposal of materials; availability of water, electricity and roads; uncertainties of weather, Larimer and Weld Canal water use schedule and construction requirements, or similar physical conditions at the site; the conformation and conditions of the ground; the equipment and facilities needed preliminary to and during the execution of the work; and all other matters which can in any way affect the work or the cost thereof under this Contract. The Contractor further acknowledges that he has satisfied himself as to the character, quality and quantity of surface and subsurface materials to be encountered from his inspection of the site and from reviewing any available records of exploratory work furnished by the Owner or included in these Documents. Failure by the Contractor to acquaint himself with the physical conditions of the site and all the available information will not relieve him from responsibility for properly estimating the difficulty or cost of successfully performing the work. The Contractor warrants that as a result of his examination and investigation of all the aforesaid data that he can perform the work in a good and workmanlike manner and to the satisfaction of the Owner. The Owner assumes no responsibility for any representations made by any of its officers or agents during or prior to the execution of this Contract, unless (1) such representations are expressly stated in the Contract, and (2) the Contract expressly provides that the responsibility therefore is assumed by the Owner. B. Information on Site Conditions: Any information obtained by the Engineer regarding site conditions, subsurface information, groundwater elevations, existing construction of site facilities, and similar data will be available for inspection, as applicable, at the office of the Engineer upon request. Such information is offered as supplementary information only. Neither the Engineer nor the Owner assumes any responsibility for the completeness or interpretation of such supplementary information. 1. Differing Subsurface Conditions: a. In the event that the subsurface or latent physical conditions are found materially different from those indicated in these Documents, and differing materially from those ordinarily encountered and generally recognized as inherent in the character of work covered in these Contract Documents, the Contractor shall promptly, and before such conditions are disturbed, notify the Engineer in writing of such changed conditions. 0 College/Willox Improvement Project Project Special Provisions REVISION OF SECTION 104 SCOPE OF WORK b. The Engineer will investigate such conditions promptly and following this investigation, the Contractor shall proceed with the work, unless otherwise instructed by the Engineer. If the Engineer finds that such conditions do so materially differ and cause an increase or decrease in the cost of or in the time required for performing the work, the Engineer will recommend to the Owner the amount of adjustment in cost and time he considers reasonable. The Owner will make the final decision on all Change Orders to the Contract regarding any adjustment in cost or time for completion. 2. Underground Utilities: Known utilities and structures adjacent to or encountered in the work are shown on the Drawings. The locations shown are taken from existing records and the best information available from existing utility plans and potholing. However, it is expected that there may be some discrepancies and omissions in the locations and quantities of utilities and structures shown. Those shown are for the convenience of the Contractor only, and no responsibility is assumed by either the Owner or the Engineer for their accuracy or completeness. C. Execution: 1. Notify private owners of adjacent properties, utilities, irrigation canals, and affected government agencies when prosecution of Work may affect them. 2. Where the Contractor's operations could cause damage or inconvenience to railway, telegraph, telephone, television, oil, gas, electricity, water, sewer, or irrigation systems, and the operations shall be suspended until all arrangements necessary for the protection of these utilities and services have been made by the Contractor. 3. Notify all utility offices which are affected by the construction operation at least 48 hours in advance. Under no circumstances expose any utility without first obtaining permission from the appropriate agency. Once permission has been granted, locate, expose, and provide temporary support for all existing underground utilities. 4. The Contractor shall protect all utility poles from damage. If interfering power poles, telephone poles, guy wires, or anchors are encountered, notify the Engineer and the appropriate utility company at least 48 hours in advance of construction operations to permit the necessary arrangements for protection or relocation of the interfering structure. 5. The Contractor shall be solely and directly responsible to the owner and operators of such properties for any damage, injury, expense, loss, inconvenience, delay, suits, actions, or claims of any character brought because of any injuries or damage which may result from the construction operations under this Contract. 6. Neither the Owner nor its officers or agents shall be responsible to the Contractor for damages as a result of the Contractor's failure to protect utilities encountered in the work. 7. If the Contractor, while performing the Contract, discovers utility facilities not identified in the Drawings or Specifications, he shall immediately notify the Owner, utility, and the Engineer in writing. 8. In the event of interruption to domestic water, sewer, storm drain, or other utility services as a result of accidental breakage due to construction operations, promptly notify the proper authority. RM College/Willox Improvement Project Project Special Provisions REVISION OF SECTION 104 SCOPE OF WORK Cooperate with said authority in the restoration of service as promptly as possible and bear all costs of repair. 9. The Contractor shall replace, at his own expense, any and all other existing utilities or structures removed or damaged during construction, unless otherwise provided for in these Contract Documents or ordered by the Engineer. 10. Interfering Structures - The Contractor shall take necessary precautions to prevent damage to existing structures whether on the surface, aboveground, or underground. An attempt has been made to show major structures on the Drawings. The completeness and accuracy cannot be guaranteed, and it is presented simply as a guide to avoid known possible difficulties. 11. Field Relocation - During the progress of construction, it is expected that minor relocations of the work will be necessary. Such relocations shall be made only by direction of the Engineer. If existing structures are encountered that prevent the construction, and that are not properly shown on the Drawings, notify the Engineer before continuing with the construction in order that the Engineer may make such field revision as necessary to avoid conflict with the existing structures. If the Contractor shall fail to so notify the Engineer when an existing structure is encountered, and shall proceed with the construction despite the interference, he shall do so at his own risk. D. Easements: Where portions of the work are located on public or private property, easements and permits will be obtained by the Owner. Easements will provide for the use of the property for construction purposes to the extent indicated on the easements. Copies of these easements and permits are available upon request to the Owner. It shall be the Contractor's responsibility to determine the adequacy of the easement obtained in every case and to abide by all requirements and provisions of the easement. The Contractor shall confine his construction operations to within the easement limits or make special arrangements with the property owners or appropriate public agency for the additional area required. Any damage to property, either inside or outside the limits of the easements provided by the Owner, shall be the responsibility of the Contractor as specified herein. The Contractor shall remove, protect, and replace all fences or other items encountered on public or private property. Before final payment will be authorized by the Engineer, the Contractor will be required to furnish the Owner with written releases from property owners or public agencies where side agreements or special easements have been made by the Contractor or where the Contractor's operations, for any reason, have not been kept within the construction right-of-way obtained by the Owner. E. Land Monuments: The Contractor shall notify the Engineer of any existing Federal, State, Town, County, and private land monuments encountered.

Retain all spent oils, hydraulic fluids and other petroleum fluids in containers for disposal off the site. 2. Prevent sediment, debris or other substances from entering sanitary sewers, storm drains and culverts. C. Preservation of Natural Features: Confine operations as much as possible. Exercise special care to maintain natural surroundings in an undamaged condition. Within the work limits, barricade trees, rock outcroppings, and natural features to be preserved. 1. Tree Barriers: All trees which will be preserved, but are within the limits of construction, must be protected from all damage associated with construction. A sturdy, physical barrier (fluorescent orange in color) must be fixed in place around each tree for the duration of construction. This barrier will be placed no closer than six (6) feet from the trunk, or one-half of the drip line, whichever is greater. The barrier itself must be fixed so it cannot be moved easily, but the material can be flexible, such as orange safety fence attached to metal T-posts driven into the ground, but must act as an effective deterrent to deliberate or accidental 26 College/Willox Improvement Project Project Special Provisions REVISION OF SECTION 107 ENVIRONMENTAL CONTROLS damage of each tree. The Project Engineer or Manager must approve actual materials and location of barrier. The movement or storage of equipment, material, debris, or fill within these required protective barriers is completely prohibited. In situations where the construction will come closer to a tree than six (6) feet, the orange barrier must still be erected. However, additional padding must be placed around the trunk of each tree starting at ground level and proceeding up the trunk to a height of six or seven feet. Padding should be a minimum eight (8) inches thick, and made of a material strong enough to protect the bark from accidental impacts with hand tools or power equipment. 2. Accidental Poisoning: During the construction, the Contractor shall not cause, or permit the cleaning of equipment or material within the root zone of any tree. The Contractor shall not store or dispose of waste material including, but not limited to; paints, solvents, asphalt, concrete, mortar, or any other material harmful to the life of a tree, within the root zone of each tree, or group of trees. 3. Root Pruning Specifications: When the cutting of tree roots is necessary, each final cut must be made as cleanly as possible for all roots over three (3) inches in diameter using the following method: a. The line of excavation will be drawn out and appropriate excavation equipment used to clear the area at least six inches in front of the actual finished excavation line. Roots can then be cut using tools such as axes, stump grinders, or trenchers. b. Each root over three (3) inches in diameter will then be cut cleanly back to the excavation line using a stump grinder operated by an experienced licensed arborist. A sharp hand or bow saw is acceptable for roots under three (3) inches in diameter. Axes and trenchers do not cut roots cleanly and will not be used for final root cuts. 4. Contractor shall coordinate with the Owners' Field Representative prior to and during the installation of tree protection and root pruning activities. Owners' Field Representative, at his/her opinion, will contact the City Forester and/or City Arborist for advice and approval of the tree protection measures taken by the Contractor and also the City's advice and approval during the root pruning activities. No damaging attachments, wires, signs, permits or other objects may be fastened by any means to any tree preserved on this project. 6. Violation of Specifications and Penalties for Damaging Trees: a. Any violation of these specifications will lead to penalties based on the type of violation and/or the resulting damages, and may be grounds for the termination of this contract. b. The penalties will be assessed based on the amount of damage done and the total value of that tree, or group of trees, prior to the damage. The minimum penalty will be $100.00. Penalties for any damage will be based on the total value of the tree as determined by the City Forestry Division staff and the severity of the damage as a proportion of the total value of that tree. This could include up to the full value of the tree. 27 College/Willox Improvement Project Project Special Provisions REVISION OF SECTION 107 ENVIRONMENTAL CONTROLS As an example, there are two American Elm trees to be preserved on another project. They are valued at $7,960 and $6,667 for the south and north trees respectively. The south tree is approximately 100 inches in circumference; therefore each inch is worth one -hundredth of the value, or $79.60 per inch. Similarly, the north tree is 91 inches in circumference, making each inch worth $73.26. To extend this to penalties paid, if one inch of the bark on the south tree is scuffed, the penalty would be $100 (the minimum allowed); if two inches are damaged, the penalty would be $159.20 and so on up to 50% of the circumference of the trunk. If 50% or more is damaged, the full value of the tree will be assessed as a penalty. (This example serves to illustrate how damages will be assessed). d. This method of assessing penalties will be applicable to all trees not marked for removal on the project, accidental poisoning and improper pruning. D. Housekeeping: 1. Execute cleanup, during progress of the Work, and at the completion of the Work. 2. Keep project neat, orderly, and in a safe condition at all times. 3. Store and use equipment, tools, and materials in a manner that does not present a hazard. 4. Immediately remove all rubbish. Do not allow rubbish to accumulate. 5. Provide on -site covered containers for collection of rubbish and dispose of it at frequent intervals during progress of work. 6. Store volatile wastes in covered metal containers and dispose off site. 7. The streets adjacent to the construction area shall be cleaned of debris generated by the project by the Contractor at the earliest opportunity, but in no case shall the street be left unclean after the completion of a day's work. It shall be the Contractor's responsibility to provide the necessary equipment and materials to satisfactorily clean the roadway at no additional cost to the project. The City's Street Department will sweep the street at an approximate hourly rate of $90.00 for a minimum of 2 hours. The Contractor must sign a Contract with the City Street Department prior to requesting street sweeping. Construction "DRAG OUT" will not be tolerated. The Contractor must have the means to sweep, wash and scrape the roadway clear of any materials drug out by construction traffic on -site. The Contractor will monitor his construction traffic and clean as necessary or as directed by the on -site Project Engineer. If the streets are not cleaned by the Contractor within 24 hours after having been given notice from the Project Engineer, the Project Engineer will have the Streets Department sweep the streets at the rates listed above and will back charge the Contractor for expenses incurred. 8. Adequate cleanup will be a condition for recommendation of progress payments. E. Disposal 1. Disposal of Waste (Unsuitable) Materials: All material determined by the Engineer to be waste will be disposed of in approved landfill in a manner meeting all regulations. Dispose of waste materials, legally, at public or private dumping areas. Do not bury or burn wastes inside of the limits of construction.

D. Owner's Responsibility 1. Owner's review is only for the purpose of checking conformity with the Contract Documents and assisting the Contractor in coordinating the Work with the needs of the Project. 2. It is not to be construed as relieving contractor from any responsibility to determine the means, methods, techniques, sequences and procedures of construction. Modifications to Time of Completion in the Approved Schedule The date of beginning and the time for completion of the work are essential conditions of the Contract Documents and the work embraced shall be commenced on a date specified in the Notice to Proceed. The Contractor will proceed with the work at such rate of progress to ensure full completion within the contract time. It is expressly understood and agreed, by and between the Contractor and the Owner that the contract time for the completion of the work described herein is a reasonable time, taking into consideration the climatic and other factors prevailing in the locality of the work. 34 College/Willox Improvement Project Project Special Provisions REVISION OF SECTION 108 PROSECUTION AND PROGRESS Every effort shall be made by the Contractor to complete the project within the "Contract Time" shown in the proposal. The "Contract Time" anticipates "Normal" weather and climate conditions in and around the vicinity of the Project site during the times of year that the construction will be carried out. Extensions of time based upon weather conditions shall be granted only if the Contractor demonstrates clearly that such conditions were "unusually severe," would not have been reasonably anticipated, and that such conditions adversely affected the Contractor's work and thus required additional time to complete the work. The following specifies the procedure for the determination of time extensions for unusually severe weather. The listing below defines the anticipated number of calendar days lost to adverse weather for each month and is based upon National Oceanic and Atmospheric Administration (NOAA) or similar data for the geographic location of the project. Monthly Anticipated Calendar Days Lost to Adverse Weather Conditions JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC (7) (4) (4) (4) (6) (3) (4) (2) (3) (3) (2) (5) The above schedule of anticipated adverse weather will constitute the base line for monthly (or portion thereof) weather time evaluations. Upon acknowledgment of the Notice to Proceed and continuing throughout the contract on a monthly basis, actual adverse weather days and the impact of adverse weather days that delay the work will be recorded on a day-to-day basis. It is assumed that the work will be carried out Mondays through Fridays (holidays accepted) unless an approved construction schedule or written authorization from the Owner indicates otherwise. The number of days of delayed work due to adverse weather or the impact thereof will then be compared to the monthly adverse weather schedule above. An actual adverse weather day must prevent work for 50 percent or more of the Contractor's workday, delay work critical to the timely completion of the project, and be documented by the Contractor. The City Representative observing the construction shall determine on a daily basis whether or not work can proceed or if work is delayed due to adverse weather or the effects thereof. The Contractor shall notify the Engineer in writing of any disagreement as to whether or not work can proceed on a given date, within 2 calendar days of that date. The Owner will use the above written notification in determining the number of working days for which work was delayed during each month. At the end of each month, if the number of working days for which work was delayed due to adverse weather exceeds that shown in the above schedule, a Change Order will be executed which increases the Contract Time. The number of work days delayed due to adverse weather or the impact thereof will then be converted to Calendar Days based on the contract completion day and date. This conversion assumes a 5-day work week, Mondays through Fridays, holidays excepted; should the Contractor have authorization to work weekends and/or holidays, and then the method of conversion of workdays to calendar days would take this into consideration. The contract time period will then be increased by the number of calendar days calculated above and a new contract completion day and date will be set. The Contractor's schedule must reflect the above -anticipated adverse weather delays on all weather -dependent activities. While extensions of time shall be granted for "unusually severe" weather or climate conditions, the Owner shall make no monetary compensation for any costs to the Contractor arising out of such delays. The Contractor shall 35 College/Willox Improvement Project Project Special Provisions REVISION OF SECTION 108 PROSECUTION AND PROGRESS comply with the portions of the Contract Documents relating to his project schedule and amendments thereto which result from the "unusually severe" weather condition. Breakdowns in equipment or lack of performance by the Contractor will not be considered justification for an extension of time. Liquidated damages will be assessed as delineated elsewhere. The Contractor shall not be charged with liquidated damages or any excess cost when the delay in completion of the work is due to the following, and the Contractor has promptly given written notice of such delay to the Owner or Engineer. 1. To any preference, priority, or allocation order duly issued by the Owner. 2. To unforeseeable causes beyond the control and without the fault or negligence of the Contractor, including but not restricted to, acts of God, or of the public enemy, acts of the Owner, acts of another Contractor in the performance of a contract with the Owner, fires, floods, epidemics, quarantine restrictions, strikes, freight embargoes, and abnormal and unforeseeable weather as provided above. 3. To any delays of Subcontractors occasioned by any of the causes specified in paragraphs 1 and 2, above. Work Hours: Standard work hours are 7 AM to 6 PM, Monday through Friday. No work shall be permitted on weekends or holidays without written approval from the Project Manager. All lane drops shall take place during the hours of 8:30 AM to 3:30 PM, Monday through Friday. Work requests beyond normal working hours must be submitted to the Project Manager a minimum of (5) working days prior to the request date. 36 College/Willox Improvement Project Project Special Provisions REVISION OF SECTION 201 CLEARING AND GRUBBING Section 201 of the standard specifications is hereby revised for this project as follows: Subsection 201.02 shall include the following: Ralph Zentz, Assistant City Forester (970-221-6302), shall be responsible for identifying the removal of tree branches, stumps, shrubs and/or other plant materials beyond those trees identified in the removal plans for removal and/or transplant.

The Contractor is encouraged to develop and offer proposals for improved construction techniques, alternative materials and other innovations. Proposals must provide a project comparable to the CDOT's original design either at lower cost or improved quality, or both. No proposals will be accepted that lowers the quality of the intended project. Bid prices shall not be based on the anticipated approval of a Value Engineering Change Proposal (VECP). Proposals shall be submitted only by the successful bidder after contract award. If a VECP is rejected, the work shall be completed in accordance with the Contract at contract bid prices. Any delay to the project due to a VECP submittal and review shall be considered within the Contractor's control and will be non -excusable with the exception of those delays that are approved as part of the VECP. Proposals shall be categorized as VECP (Category A) or VECP (Category B). VECP (Category A)s will be all proposals that involve the design and construction of a structure including but not limited to a bridge, retaining wall, concrete box culvert, or building. A VECP (Category A) will also include any proposal that would result in a change of original bid items that totals over $250,000. Alternatives investigated and not selected in the project Structural Selection Reports may be presented in a VECP, if significant benefits can be demonstrated to the Engineer. In addition, any design criteria and constraints listed in the Structural Selection Report can not be modified or relaxed as part of a VECP unless significant and previously unknown benefits can be proven to the Engineer. Experimental or demonstration -type design concepts, products, structures, or elements that have not been pre -approved by CDOT, in writing, for general use will be considered a VECP (Category A). Category A proposals will also result in a realized and shared cost savings to CDOT. Cost savings generated to the Contract as a result of VECP offered by the Contractor and accepted by the CDOT shall be shared between the Contractor and the CDOT. All other VECPs that do not meet the previous requirements will be classified as a VECP (Category B). Net cost savings on VECPs that are less than $25,000 can be kept by the Contractor. Net cost savings greater than $25,000 shall be split equally between the Contractor and CDOT as defined in the Basis of Payment section of this specification. Both VECP (Category A) and VECP (Category B) will produce savings to the CDOT or provide improved project quality without impairing essential functions and characteristics of the facility. Essential functions include but are not limited to: service life, requirements for planned future development, prior commitments to governmental agencies or the public, corridor requirements, economy of operation, ease of maintenance, desired appearance, safety, and impacts to the traveling public or to the environment during and after construction. The Contractor may submit either a full VECP or a preliminary Conceptual VECP, followed by a full proposal. These proposals are subject to rejection at any time if they do not meet the criteria outlined in this subsection. (a) Submittal of Conceptual Proposal. For a VECP (Category A) that requires a significant amount of design or other development resources, the Contractor may submit an abbreviated Conceptual Proposal for preliminary evaluation. The Engineer will evaluate the information provided. The Contractor will then be advised in writing if any conditions or parameters of the Conceptual Proposal are found to be grounds for rejection. Preliminary review of a conceptual proposal reduces the Contractor's risk of subsequent rejection but does not commit the CDOT to eventual approval of the full VECP. The following information shall be submitted for each Conceptual Proposal: August 1, 2005 2 REVISION OF SECTION 104 VALUE ENGINEERING CHANGE PROPOSALS (1) Statement that the proposal is submitted as a Conceptual VECP (2) General description of the difference between the existing Contract and the proposed change, and the advantages and disadvantages of each, including effects on service life, requirements for planned future development, prior commitments to governmental agencies or the public, corridor requirements, economy of operation, ease of maintenance, desired appearance, safety, and impacts to the traveling public or to the environment during and after construction.

Right of Way cannot be bought as part of a VECP to eliminate phasing on a project. 11. A VECP changing the design of a structure maybe considered by the CDOT, if the design meets the following conditions: (1) The design shall not involve detouring of traffic onto local roads or streets to an extent greater than the original plans, unless previously approved by the affected local agencies (2) The design has the same roadway typical section as the original plans (3) The design meets or exceeds the benefits of the construction -handling or traffic phasing scheme shown in the original plans (4) The design meets or exceeds all environmental commitments and permit requirements of the original Contract. (5) The design shall not increase environmental impacts beyond those of the original Contract. (6) The design meets or exceeds the vertical and horizontal clearances and hydraulic requirements shown in the original plans (7) The design has the same or greater flexibility as the original design to accommodate future widening (8) The design shall not change the location of the centerline of the substructure elements, without demonstrating substantial benefits over the original plans (9) The design shall not charige the grade or elevation of the final riding surface, without demonstrating substantial benefits over the original plans (10) The design shall match corridor future development plans, architectural, aesthetic and pavement requirements, if applicable (11) The design shall not adversely impact the CDOT's Bridge Inspection, maintenance or other long- term costs or operations. (12) The design shall meet all CDOT design standards and policies (13) The design shall include all additional costs and coordination necessary to relocate utilities (14) Major structure designs provided by the Contractor shall include an independent plan review and design check by a Professional Engineer registered in the State of Colorado and employed by a firm other than the engineer -of -record. This design review will be performed at no additional cost to CDOT and shall be included in the Contractor's engineering costs. (15) The Contractor shall provide CDOT with all design calculations, independent design check calculations, a rating package for each bridge prepared in accordance with the current CDOT Bridge Rating Manual, and a record set of quantity calculations for each structure. 12. The Engineer will reject all or any portion of the design or construction work performed under an approved VECP if unsatisfactory results are obtained. The Engineer will direct the removal of such rejected work and require construction to proceed under the original Contract requirements without reimbursement for work performed under the proposal, or for its removal. If a structure design VECP meets these and all other requirements, the CDOT may, at its sole option, accept or reject the proposal. (d) Basis of Payment. If the VECP is accepted, a Contract Modification Order will authorize the changes and payment. Reimbursement will be made as follows: August 1, 2005 5 REVISION OF SECTION 104 VALUE ENGINEERING CHANGE PROPOSALS 1. The changes will be incorporated into the Contract by changes in quantities of unit bid items, new agreed unit price items, lump sum or any combination, as appropriate, under the Contract. Unless there is a differing site condition as described in subsection 104.02, the Contractor shall not receive additional compensation for quantity overruns, design errors, supplemental surveys, geotechnical investigations, additional items or other increases in cost that were not foreseen in the accepted VECP, unless otherwise approved by the Engineer. 2. For all VECPs, the incentive payment shall be calculated as follows: (gross cost of deleted work) - (gross cost of added work) _ (gross savings) (gross savings) - (Contractor's engineering costs) - (CDOT's engineering costs) _ (net savings) Any net savings less than $25,000 can be kept by the contractor. If the net savings are greater than $25,000 then the amount over $25,000 will be shared equally with CDOT and calculated as follows: (net savings)- $25,000 = shared savings Contractor's total incentive = (shared savings) /2 + $25,000 The Contractor's engineering costs will be reimbursable only for outside consultant costs that are verified by certified billings. CDOT's engineering costs shall be actual consultant costs billed to CDOT and extraordinary in-house personnel labor costs. These labor costs will be calculated at the fixed amount of $50.00 per hour per employee. Project personnel assigned to the field office or who work on the project on a regular basis shall not be included in CDOT's portion of the cost. 3. At the completion of the VECP design work, the Contractor shall furnish the CDOT any additional documentation such as surveys, geotechnical reports, documentation or calculations and shop drawings required to complete the work. At the completion of the project, the Contractor shall furnish the CDOT with PE -stamped Record sets, and As -Constructed plans showing the VECP work. (e) Contractor Appeal Process. Appeals can only be made on VECP (Category A)s. The Prime Contractor submitting the VECP may file a one-time appeal to the Region Transportation Director (RTD) on the denial of any VECP (Category A). The Contractor must have a valid reason for the appeal and the decision of the Region Transportation Director will be final. January 17, 2008 REVISION OF SECTION 105 CONFORMITY TO THE CONTRACT Section 105 of the Standard Specifications is hereby revised for this project as follows: Subsection 105.03 shall include the following, after the first paragraph: All Hot Mix Asphalt (HMA) materials or work will be evaluated for conformity to the Contract in accordance with subsection 105.05 except HMA that is used for patching and temporary pavement. In subsection 105.03 (c), delete the Table of Price Reduction Factors and replace with the following: TABLE OF PRICE REDUCTION FACTORS Element Factor "F" 100 percent size sieve 1 12.5 mm ('/2") sieve and larger 1 150 pm (No. 100) sieve to 9.5 mm (3/8°) sieve inclusive _(except 100 percent size sieve) 3 . 75 pm (No. 200) sieve 6 750m {No. 200) sieve (cover coat material) 25 Liquid Limit 3 Plasticity Index 10 Asphalt penetration 1 Asphalt residue 3 Portland Cement Concrete Pavement Fine Aggregate Sand Equivalent 0.3 Hydrated Lime Gradation 0.3 Toughness, inch -pounds, minimum 0.8 Tenacity, inch -pounds, minimum 0.8 Elastic Recovery, 25 °C, percent minimum 1.25 Ductili , 4 'C 5cm/min) cm, minimum 1:25 In subsection 105.03 (c), delete the seventh paragraph, including the table of the multiplier for price reductions, and replace with the following: If the P for aggregate gradation for Items 206, 304, or the gradation of hydrated lime for item 403 is 3 or greater the reduction will apply to the contract price multiplied by the Multipliers (M) listed in the following table: MULTIPLIER FOR PRICE REDUCTIONS FOR MISCELLANEOUS ITEMS Item Number -Name Element Multiplier M 206- Structural Backfill Gradation 0.60 304-Aggregate Base Course Gradation 0.60 403-Hot Mix Asphalt* Hydrated Lime Gradation 0.60 * The P value for hydrated lime shall be applied to the price of the HMA item when asphalt cement is not paid for separately.

July 3, 2008 1 REVISION OF SECTION 105 CONFORMITY TO THE CONTRACT OF SUPERPAVE PERFORMANCE GRADED BINDERS Section 105 of the Standard Specifications is hereby revised for this project as follows: Delete subsection 105.04 and replace with the following: 105.04 Conformity to the Contract of Superpave Performance Graded Binders. Asphalt binders will be price reduced according to the following if the requirements of subsection 702.01 are not met: (1) TABLE OF PERFORMANCE GRADED BINDER LIMITS Compliance Limit for Rejection Limit, Property Specification Price Reduction of Price Reduction = 0% 25% G*sin (delta) of RTFO 2.20 Min :', 1 87.Min < 1.53 Residue Slope (m-value) of the Creep Curve at Low Grade Temperature + 0.300 Min 0.295 Min < 0.266 100 C. Stiffness of the PAV Residue at Low Grade .Temperature + 107C, 300 Max.311 Max >355 The price reduction will be 25 percent at the rejection limit. Between the compliance limit and the rejection limit, the price reduction will be calculated as follows: PR = 25 • CL — test value CL —RL Where: PR = Price Reduction CL = Compliance Limit RL = Rejection Limit (2) The price reductions will be cumulative if more than one PG binder property specified in the Table of Performance Graded Binder Limits is out of specification, resulting in P(total). When binder is included in the contract unit price for HMA, the price reduction will be calculated as follows: Amount of Reduction = [P(total)] • [(1/100) • (Invoice Price for PG Binder)] When the binder is paid for separately, the total price reduction will be calculated as follows: Amount of Reduction = [P(total)] • [(1/100) • (Contract Unit Price for PG Binder)] (3) Price reductions based on the "F" factors in the Table of Price Reduction Factors described in subsection 105.03 will be in addition to the PG binder price reductions. Other binder requirements listed in the Table of Performance Graded Binder Limits but not price reduced in subsections 105.03 or 105.04 may be tested, but will not be considered for price reduction calculations. However, the Contractor will not be allowed to continue to produce mix without of specification PG binder. If two consecutive. samples fail to meet all requirements listed in the Table of Performance Graded Binder Limits, the Contractor shall take corrective action before being allowed to continue production of Hot Mix Asphalt. If proper corrective measures cannot July 3, 2008 2 REVISION OF SECTION 105 CONFORMITY TO THE CONTRACT OF SUPERPAVE PERFORMANCE GRADED BINDERS be readily determined, the Engineer will suspend the use of such material until the Engineer can determine from laboratory tests that the Contractor can provide material that is in compliance with the Table of Performance Graded Binder Limits. The Contractor will not have the option of accepting a price reduction in lieu of producing specification material. Continued production of non -specification material will not be permitted. Material which is obviously defective may be isolated and rejected without regard to sampling sequence or location within a lot.

The Contractor may request that the 2 percent above SSD requirement be waived, provided the requirements of CPL 5150 have been met. If the HMA fails to meet the minimum TSR requirements defined in Table 401-2 at any point during production, the Contractor shall immediately be required to add the minimum amount of moisture as defined above. January 17, 2008 REVISION OF SECTION 401 PROCESSING OF ASPHALT MIX DESIGN Section 401 of the Standard Specifications is hereby revised for this project as follows: In subsection 401.02 (a), delete the third paragraph October 25, 2007 REVISION OF SECTION 401 TEMPERATURE SEGREGATION Section 401 of the Standard Specifications is hereby revised for this project as follows: Subsection 401.16 shall include the following: The Engineer will perform a systematic segregation check in accordance with CP 58 as early in the project as is feasible to determine if temperature segregation problems exist. Temperature segregation will be of concern on the project if, across the width of the mat, temperatures vary by 25 °F or more. Densities will not need to be taken in the systematic segregation study. The Engineer will discuss the temperature findings of the systematic segregation check with the Contractor. The Engineer may evaluate the HMA for low density due to temperature segregation any time industry best practices, as detailed on Form 1346, are not being followed or the Engineer suspects temperature segregation is occurring. The Engineer will first meet with the Contractor to discuss the paving practices that are triggering the temperature investigation. Areas across the mat, excluding the outside 1 foot of both edges of the mat, that are more than 25 °F cooler than other material across the width may be marked for density testing. Material for temperature comparison will be evaluated in 3-foot intervals behind the paver across the width of the mat. The material shall be marked and tested in accordance with CP 58. If four or more areas within a lot of 500 tons have densities of less than 92 percent of the material's maximum specific gravity, a 5 percent price disincentive will be applied to the 500 ton lot. The 500 ton count begins when the Engineer starts looking for cold areas, not when the first cold area is detected. This price disincentive will be in addition to those described in Sections 105 and 106. Only one area per delivered truck will be counted toward the number of low density areas. Temperature segregation checks will be performed only in areas where continuous paving is possible. January 17, 2008 REVISION OF SECTION 401 TOLERANCES FOR HOT MIX ASPHALT Section 401 of the Standard Specifications is hereby revised for this project as follows: In subsection 401.02(b) delete Table 401-1 and replace with the following: Table 401-1 TOLERANCES FOR HOT MIX ASPHALT As haft Content t 0.3% Asphalt Recycling Agent t 0.2% 'Hot Mix Asphalt — Item 403 ZPassing the 9.5 mm (3/8 inch) and larger sieves t 6% ZPassinq the 4.75 mm No. 4 and 2.36 mm No. 8 sieves t 5% ZPassing the 600 µm (No. 30) sieve t 4% 2 Passing the 75 prn No. 200 sieve t 2% ' 'When 100% passing is designated, there shall be no tolerance.

The pay quantity of emulsified asphalt will be determined from the invoices of emulsified asphalt delivered to the project, corrected by any weight of remaining emulsion in the distributor truck or tanker at the conclusion of the project. The Engineer may elect to calculate the remaining weight in a distributor by use of the average specific gravity of materials delivered, or by tank stabs. The average specific gravity for this calculation will be as determined by Central Laboratory Testing. If tank stabs are to be utilized for this measurement, the Contractor's quality control plan shall include appropriate information for calculations on the distributor used on the project. This calculation will be limited to 4000 gallons of material. All other material shall require weigh back for proper calculation of payment. The weight shall be determined by certified scales in accordance with Section 109. This will also be monitored and documented by daily distributor gauge readings and yield calculations. All proposed methods of weighing materials, calibrating distributor rates and monitoring the yields shall be included in the Quality Control Plan in accordance with Section 409. Diluted emulsified asphalt used for fog coat in chip seals will be measured by the actual number of tons of asphalt prior to dilution with water. Correction for the final diluted emulsion at the conclusion of a project will assume a 3:2 emulsion to water dilution rate, and the water subtracted from the weight of the remaining product unless otherwise approved. Subsection 411.05 shall include the following: Pay Item Pay Unit Emulsified Asphalt (Rapid -Setting) (Polymerized) Ton Emulsified Asphalt (Medium -Setting) (Polymerized) Ton Water will not be measured and paid for separately but shall be included in the work.

Tining shall produce grooves of /8 inch by inch spaced 3/4 inch apart and parallel to the longitudinal joint. Longitudinal tining shall stop at the edge of travel lanes. Tining devices shall be maintained clean and free from encrusted mortar and debris to ensure uniform groove dimensions. The tining finish shall not be performed too early whereby the grooves may close up. Before paving the Contractor shall provide in writing a tining plan showing tining locations and describing methods that will be used for hand tining. Paving shall not commence until the Engineer has approved the tining plan in writing. The tining grooves shall be neat in appearance, parallel with the longitudinal joint, uniform in depth and in accordance with what is shown in the plans and these specifications. Any time that the tining grooves do not meet these requirements, the concrete paving operation shall be immediately stopped and will not resume until the problem has been resolved. Stationing shall be stamped into the outside edge of the pavement, as shown on the plans. November 5, 2009 1 REVISION OF SECTION 412 REPAIR OF DEFECTIVE CONCRETE PAVEMENT Section 412 of the Standard Specifications is hereby revised for this project as follows: Delete subsection 412.16 and replace with the following: 412.16 Repair of Defective Concrete Pavement.

If the spalled area, to be repaired, abuts a working joint or a working crack which penetrates the full depth of the pavement, an insert or other bond -breaking medium shall be used to maintain the working joint or crack during the repair work. Concrete paving that exhibits the above defects for two or more days production will be suspended. The Contractor shall submit a written plan to correct these defects. The plan shall detail at a minimum changes in paving procedures, materials and equipment required to construct concrete pavement that meets the specifications. The Engineer will approve the Contractor's plan prior to the continuation of the concrete paving operation. February 25, 2010 REVISION OF SECTION 601 STRUCTURAL CONCRETE ACCEPTANCE Section 601 of the Standard Specifications is hereby revised for this project as follows Subsection 601.17 (c), after the Td paragraph, shall include the following: The Engineer may use cores to determine acceptance or rejection of a part of the structure instead of acceptance cylinders. The Engineer will notify the Contractor within 10 working days after concrete placement that CDOT may core the structure. The location of the coring will be directed by the Engineer. Coring and testing will be performed at the expense of the Department regardless of the result. Cores will be taken and tested in accordance with AASHTO T24 between 28 days and 45 days after concrete placement. Cores will be a minimum of 4 inches in diameter, unless otherwise approved by the Engineer. A minimum of three cores in a two square foot area will be obtained for locations of the structure that are suspect. If the compressive strength of any one core differs from the average by more than 10 percent that compressive strength will be deleted and the average strength will be determined using the compressive strength of the remaining two cores. If the compressive strength of more than one core differs from the average by more than 10 percent the average strength will be determined using all three compressive strengths of the cores. If the average core compressive strength is greater than or equal to 85 percent of the specified 28 day compressive strength, the concrete represented by the cores will be accepted. If the average core compressive strength is less than 85 percent of the specified 28 day compressive strength, the structure will be evaluated by the Department according to subsection 105.03 for removal and replacement. Pay factors will not be based on cores taken by the Engineer. If the concrete represented by the cores is accepted, all costs associated with the repair of the core holes, including preparation and submittal of the repair method, will be measured and paid for separately. After the Department performs additional core testing as described above, the Contractor may make one request that the structure be cored and re-evaluated by the Department within 45 days after concrete placement. Coring and testing costs will be at the expense of the Contractor regardless of the result. Cores shall be taken at the same area of the structure as those obtained by the Engineer. The Engineer will approve the location of the cores prior to the Contractor coring the structure. All costs associated with the repair of these core holes, including preparation and submittal of the repair method, will not be measured and paid for separately, but shall be included in the work. If the concrete in the structure is found to be sufficient resulting time delays will be considered excusable. If the concrete in the structure is still found to be deficient, resulting time delays will be considered non -excusable for this evaluation. Compensation for time delays will be evaluated by the Engineer in accordance with subsection 108.07. The Contractor shall submit a proposed repair method for the core holes for approval prior to coring. The method shall use an approved non -shrink concrete patching material with a minimum compressive strength of 4500 psi. The Contractor shall submit the manufacturer's recommendations along with the repair method. The Engineer will review and approve the proposed methodology prior to patching.

We believe our report is in general conformance with Chapters 5 and 10 of the "Larimer County Urban Areas Street Standards" (LCUASS) dated January 2, 2001 (repealed and reenacted April 1, 2007) as adopted by the City of Fort Collins (City) as well as the Colorado Department of Transportation (CDOT) 2007 "Pavement Design Manual". We have revised this report to include another composite pavement section alternative approved by CDOT. The report was prepared from data developed during field exploration, laboratory testing, engineering analysis, and experience with similar conditions. The report includes a description of the subsurface conditions found in our exploratory borings, laboratory test results and pavement recommendations. If plans change significantly, we should be contacted to review our investigation and determine if our recommendations still apply. A brief summary of our conclusions is presented below, with more detailed criteria and recommendations contained in the report. SITE AND PROJECT DESCRIPTION The project includes improvements to portions of North College Avenue (US Highway 287) and East Willox Lane in Fort Collins, Colorado (Figure 1). The extents of the project include East Willox Lane from the intersection with North College Avenue to about 500 feet east of the intersection as well as North College Avenue from the intersection with East Willox Lane to about 1,000 feet north of the intersection at the Larimer and Weld Canal. The existing East Willox Lane is paved with asphaltic concrete over aggregate base course with curb and gutter. Originally, North College Avenue was paved with portland cement concrete that was later, in various stages, overlain with asphaltic concrete and widened with full depth asphaltic concrete and composite asphaltic concrete and aggregate base course. We observed various distresses in North College Avenue including rutting, cracking, potholes, and patching. The majority ,of the distress was observed in the portions of roadway that does not include a portland cement and asphaltic concrete section. East Willox Lane was relatively free of CITY OF FORT COLLINS ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS 1 CTL IT PROJECT NO. FC04902-135 (revised) significant distress. The planned improvements include overlay and/or reconstruction of most of the pavements, construction of a roundabout, improvements to islands, curbs, gutters, and other associated improvements. We understand the City desires recommendations for: 1.) Functional asphaltic concrete overlay for that portion of North College Avenue underlain by asphaltic concrete and portland cement concrete (PCC), 2.) Reconstruction of that portion of North College Avenue that is not underlain by PCC, 3.) Reconstruction of the College/Willox intersection, and 4.) Reconstruction or new construction of East Willox Lane and the Willox roundabout. We understand improvements to North College Avenue are regulated by CDOT standards and improvements to East Willox Lane are regulated by LCUASS. .Our Mr. Eric Bernhardt, PE, Mr. Robin Dornfest, PG, Mr. Thomas Finley, CPG met with your Mr. Matt Baker, PE and Mr. Kyle Lambrecht, PE on June 24, 2009 and later on August 12, 2009 with Mr. Rick Richter to discuss the scope of the project in more detail. We discussed providing alternative pavement sections, bike lanes and turn lanes, roundabouts, and other project scopes that are addressed in this pavement design report. FIELD AND LABORATORY INVESTIGATION Our field investigation consisted of coring the existing asphalt and concrete pavement, measuring existing aggregate base course thicknesses, and drilling eight borings to a depth of approximately 10 feet. Borings were drilled at approximate 450- foot spacing, or less. The approximate locations of our cores and borings are presented on Figure 1. Cores were drilled with a portable coring rig and 6-inch diameter, diamond core barrel. The borings were drilled with 4-inch diameter solid -stem augers and a truck - mounted drill. Our field representative observed drilling and logged the soils found in the borings. Bulk samples were obtained from the upper 4 feet of the borings and modified California samples were obtained from selected intervals within the borings. The number of blows from a 140-pound hammer falling 30 inches, required to drive the modified California sampler, were recorded. We backfilled the borings with flow fill and cold patch immediately after drilling. Summary logs of the borings, including results of field penetration resistance tests, are presented on Figure 2. CITY OF FORT COLLINS ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS 2 CTL IT PROJECT NO. FC04902-135 (revised) Samples obtained during coring and drilling were returned to our -laboratory and visually examined by the geotechnical engineer and geologist for this project. Laboratory testing was performed in general accordance with AASHTO and ASTM methods to determine index properties of the soils sampled and subgrade support values for those soil types influencing the pavement design. To evaluate potential heave, swell -consolidation testing was performed on six samples of the subgrade soils under a pressure of 150 psf as required under LCUASS. CDOT requires the swell - consolidation tests to be performed with a 200-psf surcharge pressure. However, we chose to conduct swell -consolidation testing with the 150-psf surcharge since the results would be more conservative. Other laboratory testing included moisture content, dry density, Atterberg limits, gradation, Hveem Stabilometer test (R-value) and water-soluble sulfate tests. Results of laboratory tests are presented in Appendix A and summarized in Table A -I. SUBSURFACE CONDITIONS Existing pavement materials consisted of asphaltic concrete and/or portland cement concrete and/or aggregate base course overlying the subgrade. Subsurface conditions encountered in our borings below pavement materials generally consisted of gravelly clayey sand, sandy clayey gravel, clayey sand and sandy clay. Ground water was encountered in three borings. Further descriptions of these materials are presented below. Summary logs of the borings, including results of field penetration resistance tests, are presented on Figure 2. Existing Pavement Materials Thicknesses of existing pavement materials were highly variable at our core and boring locations. Approximately 11/4 inches to 41/2 inches of asphaltic concrete over 6 inches to 8 inches of portland cement concrete was measured from core samples collected from center lanes of North College Avenue. Approximately 41/2 inches to 8 inches of asphaltic concrete was measured from core samples collected from outer lanes of North College Avenue. Approximately 8 inches to 91/2 inches of asphaltic concrete was measured from core samples collected from East Willox Lane. Aggregate CITY OF FORT COLLINS ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS 3 CTL I T PROJECT NO. FC04902-135 (revised) base course thicknesses in the roadways ranged from about 0 inches to 6 inches. Based on our experience with the City, asphalt and/or aggregate base course thicknesses are greater in patched and/or repaired areas which may have not been encountered in our borings. We conducted compressive strength tests on three concrete cores obtained from the existing pavement and correlated the compressive strengths with estimated flexural strengths as presented below in Table A.

Therefore, the test results should be considered informational only. Gravelly Sand and Sandy Gravel Loose to medium dense gravelly sand and sandy gravel with clay were encountered below the pavement materials in TH-1 and below the upper soils in TH-3, TH-5, TH-6, and TH-7. Two samples of gravelly sand tested in the laboratory contained 11 and 40 percent clay and silt -sized particles (passing the No. 200 sieve). Two of the samples had liquid limits of 26 and 28 and plasticity indices of 13 and 15. One sample was non -plastic. The gravelly sands classified as A-2-4, A-2-6 and A-6 in accordance with the AASHTO classification method with a group indices of 0 and 1. The gravelly sand and sandy gravel are considered to exhibit fair to good subgrade support.

FC04902-135 (revised) Clayey Sand Very loose to dense clayey sand was encountered below the pavement materials in TH-2, TH-5, TH-6, and TH-7 and below upper soils in TH-1, TH-3, and TH-4. One sample of clayey sand tested in the laboratory contained 40 percent clay and silt -sized particles (passing the No. 200 sieve), had a liquid limit of 30 and a plasticity index of 16. The clay classified as A-6 in accordance with the AASHTO classification method with a group index of 2. The clayey sand is considered to exhibit fair subgrade support. One sample of clayey sand tested for swell potential swelled 0.3 percent when wetted under a 150 psf confining pressure. Sandy Clay Medium stiff to very stiff, sandy clay and silty clay with occasional gravel were encountered below the pavement materials in TH-3, TH-4, and TH-8 and below the clayey sand in TH-2 and TH-6. Two samples of clay tested in the laboratory contained 50 and 65 percent clay and silt -sized particles (passing the No. 200 sieve), had liquid limits of 32 and 41 and plasticity indices of 20 and 26. The clay classified as A-6 and A- 7-6 in accordance with the AASHTO classification method with group indices of 6 and 14. The clay is considered to exhibit poor to fair subgrade support. Three samples of clay tested for swell potential swelled between 0 and 0.5 percent when wetted under a 150 psf confining pressure. OTHER INVESTIGATIONS Our firm conducted a subgrade investigation for an associated project at a site located directly northeast of the intersection of East Willow Lane and North College Avenue. During that investigation, we identified sugar beet spoils present on the site. Specifically, we encountered sugar beet spoils in borings located nearest East Willox Lane as well as observed sugar beet spoils during excavation activities near East Willox Lane. A log of an exploratory boring for a boring located nearest this project site is presented on Figure 2 (TH-1, FC04442). The sugar beet spoils present a significant risk of very poor performance of pavements and associated improvements including the CITY OF FORT COLLINS ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS 5 CTL I T PROJECT NO. FC04902-135 (revised) proposed roundabout. Our recommendations for mitigation of risk associated with sugar beet spoils are discussed in SUBGRADE AND PAVEMENT MATERIALS AND CONSTRUCTION section of this report. PAVEMENT DESIGN We understand improvements to North College Avenue (U.S. 287) are regulated by CDOT standards and improvements to East Willox Lane are regulated by LCUASS. Total reconstruction is planned for East Willox Lane and the roundabout. A functional overlay is planned for the sections of North College Avenue underlain with a bottom layer of portland cement concrete. Total reconstruction is also planned for the sections of North College Avenue not underlain with portland cement concrete (PCC). The City requires the use of the AASHTO and CDOT pavement design methods for their roadways. The design methods require various input values that are provided by the City, LCUASS, CDOT and from our field and laboratory tests and observations. We also used Asphalt Overlays for Highway and Street Rehabilitation (MS-17) published by the Asphalt Institute as a reference to develop our recommendations. Overlays are used to remedy functional or structural deficiencies. Functional deterioration is any condition that adversely affects the highway user, such as, poor surface friction and texture, hydroplaning and splash from wheel rutting, and excess surface distortion. Structural defects arise from any conditions that, adversely affect the load -carrying capability of the pavement, such as inadequate thickness as well as cracking, distortion, and disintegration. Based on our observations and calculations, none of the existing pavement thicknesses are sufficient for the design ESAL at this site. Therefore, the existing pavement may be considered structurally deficient. We conducted a structural overlay design and met with the City to discuss the results. The conclusion of the meeting was that a structural overlay was not feasible since the calculated thickness of the structural overlay was not compatible with grade requirements or restrictions of existing features. Traffic The design of a pavement section is partly dependent on the amount and type of traffic to be supported by the roadway. Both roadways are classified as arterials. In CITY OF FORT COLLINS ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS 6 CTL IT PROJECT NO. FC04902-135 (revised) order to quantify traffic conditions for the roadways, rigid and/or flexible pavement 18-kip Equivalent Single Axle Loads (ESALs) were provided by City personnel using a 20-year design life. The ESALs for collector -arterial intersections and roundabouts should be the combination of all legs entering the intersection. For the design of flexible overlays over rigid pavements, the rigid ES AL is required. Table B presents the Design ESALs used with our calculations.

To characterize the condition of the existing pavement for North College Avenue, we conducted site observations, drilled cores and conducted laboratory tests. We observed various distresses in North College Avenue including rutting, cracking, potholes, and patching. The majority of the distress was observed in the portions of roadway that does not include a portland cement and asphaltic concrete section. The condition of the existing concrete pavement was obscured by the existing asphaltic concrete overlay. However, reflective cracking in the asphaltic concrete was observed above what appears to be CITY OF FORT COLLINS ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS 7 CTL I T PROJECT NO.

Section 00520 Page 6 concrete joints. No signs of structural distress of the concrete pavement were observed at the pavement surface; however, we have assumed some defects are present. Drilled cores indicate thicknesses of the existing PCC range from 6 inches to 8 inches and the existing AC overlay range in thickness from 1'/4 inch to 41/2 inches. The majority of the 6-inch thick PCC appears to be located in the center of the roadway where new median and turn lanes are planned. The thickness of the existing PCC in the majority of the proposed reconfigured lanes is believed to be approximately 8 inches. We conducted compressive strength tests on three concrete cores from the existing pavement. Test Results are presented in Table A of the Existing Pavement Materials section of this report. Based on our limited observations and laboratory tests, we believe the existing PCC will provide adequate support for an overlay. Further observations and/or tests are recommended to evaluate the PCC pavement more thoroughly after the asphalt has been milled. Our recommendations may need to be revised pending additional observations and/or tests. Pavement Thickness Calculations We used DARWinTM software to develop our pavement thickness calculations with input values provided by the City, LCUASS, CDOT and our laboratory tests and observations. Hveem testing resulted in an R-value of 35, which we converted to a resilient modulus of 7,943 psi. Computer generated printouts of the DARWinTM calculations are presented in Appendix B. Pavement Recommendations LCUASS indicates arterial -arterial intersections are to be paved with PCC. We believe the existing pavements located in the College/Willox intersection should be completely removed and new pavements should consist of a full -depth reconstruction using PCC. Any structural defects of the existing PCC pavement observed after milling should be remedied prior to overlay placement. For pavements where full reconstruction meets the functional overlay, we recommend the thickness of each pavement layer for new pavements match the thicknesses of each pavement layer for existing pavements. CITY OF FORT COLLINS ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS 8 CTL IT PROJECT NO. FC04902-135 (revised) New PCC pavement constructed adjacent to existing PCC should be dowelled to the existing PCC pavement. Given the acceptable past performance of the portion of North College Avenue underlain by PCC pavement and grade restrictions, a functional overlay for that portion is proposed. We estimate the average proposed thickness of the overlay to meet grade requirements or restrictions is approximately 3% inches after milling the existing AC overlay. For a 31/2-inch overlay over 8 inches ,of existing PCC, we have calculated an estimated design -life of approximately 61/2 years for the reconstructed pavement. Reflective cracking of flexible overlays over rigid pavement can be problematic. Reflective cracking can be reduced or delayed by using thick overlays, crack relief layers, or use of woven geosynthetics. A recyclable geosynthetic, such as Glasgrid®, may be considered to help reduce or delay reflective cracking. Our revised pavement thickness alternatives for new and reconstructed pavements are presented on Tables C and D.

PAVEMENT SELECTION PCC pavement.will be required for the College/Willox intersection. Either HMA and ABC or PCC can be used for East Willox Lane and roundabout pavements. Composite HMA over either PCC or ABC are planned for North College Avenue. HMA and ABC over a stable subgrade are expected to perform well in areas with sandy subgrade soils. HMA provides a stiff, stable pavement to withstand heavy loading and will provide a good fatigue resistant pavement. PCC is also expected to perform well in this area. However, PCC pavement has better performance in freeze -thaw conditions and should require less long-term maintenance than HMA pavement. In any event, the performance of the pavement structure depends partly on the stability of the subgrade soils. CITY OF FORT COLLINS ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS 10 CTLIT PROJECT NO. FC04902-135 (revised) SUBGRADE AND PAVEMENT MATERIALS AND CONSTRUCTION Subgrade preparation will only apply to areas planned for total reconstruction. CDOT requires swell mitigation where swell is greater than 0.5 percent using a 200 psf surcharge. Samples tested for swell indicate no swells greater than 0.5 percent. Based on the results of laboratory testing, CDOT 2007 Pavement Design Manual and LCUASS, we believe that mitigation for swell will not be required. Sugar beet spoils were encountered during other investigations near East Willox Lane and may be encountered in the area of the proposed roundabout shown on Figure 1. If sugar beet spoils are encountered, they should be removed or mixed with other soils with no more than 20 percent of the replacement fill containing sugar beet spoils material. Historically, sugar beet spoils have contained very high contents of water- soluble sulfates which could make chemical stabilization more difficult. We understand that the City commonly uses fly ash to improve subgrade stability. Soil stabilization by chemical treatment can increase the stability of the subgrade, add strength and stiffness to the subgrade, and improve the engineering properties of the soils. If chemical stabilization is used and a laboratory mix design is performed, a reduced pavement section may be possible for Willox Lane. We can provide a soil/fly ash mix design if requested. Our threshold limit of water-soluble sulfates in soils for single application of fly ash or lime for stabilization is 0.5 percent. The CDOT threshold limit of water-soluble sulfates in soils for single application of fly ash or lime for stabilization is 0.2 percent. Based on our test results discussed in the following section, WATER-SOLUBLE SULFATES, as well as possible presence of beet spoils at the roundabout site, we believe double application of fly ash or lime should be considered for the site. Additional tests for sulfates are recommended after the subgrade has been cut or filled to rough grade. To prepare the subgrade for paving with conventional moisture treatment and compaction, subgrade soils should be scarified a minimum of 12 inches deep, moisture conditioned to within 2 percent of optimum moisture content and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D 698, AASHTO T99). CITY OF FORT COLLINS ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS 11 CTL I T PROJECT NO. FC04902-135 (revised) Scarification and recompaction of the upper 12 inches of subgrade soils should occur as close to the time of pavement construction as possible. The final subgrade surface must be protected from excessive drying or wetting until such time as the pavement section is constructed. Maintaining moisture contents near optimum will be critical to avoid excessive deflections, rutting and pumping of the subgrade during subgrade preparation of streets. If moisture and density cannot be sufficiently controlled during subgrade preparation and stabilization is required, chemical stabilization, stabilization by removal and replacement, or stabilization using geotextiles and imported granular materials may be used. For isolated or small areas requiring stabilization, removal and replacement or "crowding" crushed, coarse aggregate into the subgrade may be effective. If large areas require stabilization, chemical treatment of the soils may be a more effective alternative. The design of a pavement system is as much a function of the quality of the paving materials and construction as the support characteristics of the subgrade. The construction materials are assumed to possess sufficient quality as reflected by the strength coefficients used in the flexible pavement design calculations. Materials and construction requirements of LCUASS and CDOT should be followed. Additional criteria for subgrade preparation, paving materials and construction are presented in Appendix D. These criteria were developed from analysis of the field and laboratory data, our experience and LCUASS requirements. If the materials cannot meet these recommendations, our pavement recommendations should be reevaluated based upon available materials. Materials planned for construction should be submitted and the applicable laboratory tests performed to verify compliance with the specifications. WATER-SOLUBLE SULFATES Concrete that comes into contact with soils can be subject to sulfate attack. We measured water-soluble sulfate concentrations in two samples of clay and four samples of sand from this site. Concentrations were measured from 0.06 percent to 0.39 percent. Five of the six samples tested showed sulfate concentrations over 0.2 percent. CITY OF FORT COLLINS ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS 12 CTL IT PROJECT NO. FC04902-135 (revised) Water-soluble sulfate concentrations between 0.2 and 2 percent indicate Class 2 sulfate exposure, according to the American Concrete Institute (ACI). For sites with Class 2 sulfate exposure, ACI recommends using a cement meeting the requirements for Type V (sulfate resistant) cement or the equivalent, with a maximum water-to- cementitious material ratio of 0.45 and air entrainment of 5 to 7 percent. As an alternative, ACI allows the use of cement that conforms to ASTM C 150 Type II requirements, if it meets the Type V performance requirements (ASTM C 1012) of ACI 201, or ACI allows a blend of any type of portland cement and fly ash that meets the performance requirements (ASTM C 1012) of ACI 201. In Colorado, Type II cement with 20 percent Class F fly ash usually meets these performance requirements. The fly ash content can be reduced to 15 percent for placement in cold weather months, provided a water-to-cementitious material ratio of 0.45 or less is maintained. ACI also indicates concrete with Class 2 sulfate exposure should have a minimum compressive strength of 4,500 psi. Concrete should be air entrained. Sulfate attack problems are comparatively rare in this area when quality concrete is used. Considering the range of test results, we believe risk of sulfate attack is lower than indicated by the few laboratory tests performed. ACI indicates sulfate resistance for Class 1 exposure can be achieved by using Type II cement, a maximum water-to- cementitious material ratio of 0.50, and a minimum compressive strength of 4,000 psi. We believe this, approach should be used as a minimum at this project. The more stringent measures outlined in the previous paragraph will better control risk of sulfate attack and are more in alignment with written industry standards. The presence of sulfates in the subgrade soil, as well as historical data of high sulfate contents in sugar beet spoils can also impact the performance of chemical stabilization. Chemical stabilization is discussed in the SUBGRADE PREPARATION section of this report. SURFACE DRAINAGE The primary cause of premature pavement deterioration is infiltration of water into the pavement system. This increase in moisture content usually results in the CITY OF FORT COLLINS ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS 13 CTL IT PROJECT NO. FC04902-135 (revised) softening of base course and subgrade and eventual failure of the pavement. We recommend that pavements and surrounding ground surface be sloped to cause surface water to run off rapidly and away from pavements. Backs of curbs and gutters should be backfilled with compacted fill and sloped to prevent ponding adjacent to backs of curbs and to paving. The final grading of the subgrade should be carefully controlled so the pavement design cross-section can be maintained. Low spots in the subgrade that can trap water should be eliminated. Seals should be provided within the curb and pavement and in all joints to reduce the possibility of water infiltration. LIMITATIONS Our borings were spaced to obtain a reasonably accurate understanding of the existing pavements and subsurface conditions. The borings are representative of conditions encountered only at the exact boring locations. Variations in subsurface conditions not indicated by our borings are always possible. A representative of our firm should observe subgrade preparation and pavement construction. The recommendations contained in this report were based upon our understanding of the planned construction. This report was prepared form data developed during our field exploration, laboratory testing, engineering analysis, and experience with similar conditions. If plans change or differ from the assumptions presented herein, we should be contacted to review our recommendations. We believe this investigation was conducted in a manner consistent with that level of skill and care ordinarily used by members of the profession currently practicing under similar conditions in the locality of this project. No warranty, express or implied, is made. CITY OF FORT COLLINS ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS 14 CTL IT PROJECT NO.

GENERAL The Soils Engineer shall be the Owner's representative. The Soils Engineer shall approve fill materials, method of placement, moisture contents, and percent compaction, and shall give written approval of the completed fill. 3. CLEARING JOB SITE The Contractor shall remove all trees, brush, and rubbish before excavation or fill placement is begun. The Contractor shall dispose of the cleared material to provide the Owner with a clean, neat appearing job site. Cleared material shall not be placed in areas to receive fill or where the material will support structures of any kind. 4. SCARIFYING AREA TO BE FILLED All topsoil and vegetable matter shall be removed from the ground surface upon which fill is to be placed. The surface shall then be plowed or scarified to a depth of 8 inches until the surface is free from ruts, hummocks or other uneven features, which would prevent uniform compaction by the equipment to be used. 5. COMPACTING AREA TO BE FILLED After the foundation for the fill has been cleared and scarified, it shall be disked or bladed until it is free from large clods, brought to the proper moisture content and compacted to not less than 95 percent of maximum density as determined in accordance with ASTM D 698, AASHTO T99. 6. FILL MATERIALS On -site materials classifying as CL, SC, SM, SW, SP, GP, GC, and GM are acceptable. Fill soils shall be free from organic matter, debris, or other deleterious substances, and shall not contain rocks or lumps having a diameter greater than three (3) inches. Fill materials shall be obtained from onsite and other approved sources. 7. MOISTURE CONTENT Fill materials shall be moisture treated. Clay soils should be moisture -treated to between optimum and 3 percent above optimum moisture content as determined from Standard Proctor compaction tests. Sand soils should be moistened to within 2 percent optimum moisture content. Sufficient laboratory compaction tests shall be made to determine the optimum moisture content for the various soils encountered in borrow areas. CITY OF FORT COLLINS — ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS C-1 CTL I T PROJECT NO. FC04902-135 (revised) The Contractor may be required to add moisture to the excavation materials in the borrow area if, in the opinion of the Soils Engineer, it is not possible to obtain uniform moisture content by adding water on the fill surface. The Contractor may be required to rake or disk the fill soils to provide uniform moisture content through the soils. The application of water to embankment materials shall be made with any type of watering equipment approved by the Soils Engineer, which will give the desired results. Water jets from the spreader shall not be directed at the embankment with such force that fill materials are washed out. Should too much water be added to any part of the fill, such that the material is too wet to permit the desired compaction from being obtained, rolling, and all work on that section of the fill shall be delayed until the material has been allowed to uniformly dry to the required moisture content. The Contractor will be permitted to rework wet material in an approved manner to hasten its drying. 8. COMPACTION OF FILL AREAS Selected fill material shall be placed and mixed in evenly spread layers. After each fill layer has been placed, it shall be uniformly compacted to not less than the specified percentage of maximum density. Fill materials shall be placed such that the thickness of loose material does not exceed 8 inches and the compacted lift thickness does not exceed 6 inches. Compaction, as specified above, shall be obtained by the use of sheepsfoot rollers, multiple - wheel pneumatic -tired rollers, or other equipment approved by the Engineer. Compaction shall be accomplished while the fill material is at the specified moisture content. Compaction of each layer shall be continuous over the entire area. Compaction equipment shall make sufficient trips to insure that the required density is obtained. 9. COMPACTION OF SLOPES Fill slopes shall be compacted by means of sheepsfoot rollers or other suitable equipment. Compaction operations shall be continued until slopes are stable, but not too dense for planting, and there is no appreciable amount of loose soil on the slopes. Permanent fill slopes shall not exceed 3:1 (horizontal to vertical). 10. DENSITY TESTS Field density tests shall be made by the Soils Engineer at locations and depths of his choosing. Where sheepsfoot rollers are used, the soil may be disturbed to a depth of several inches. Density tests shall be taken in compacted material below the disturbed surface. When density tests indicate that the density or moisture content of any layer of fill or portion thereof is below that required, the particular layer or portion shall be reworked until the required density or moisture content has been achieved. 11. COMPLETED PRELIMINARY GRADES All areas, both cut and fill, shall be finished to a level surface and shall meet the following limits of construction: A. Overlot cut or fill areas shall be within plus or minus 2110 of one foot. CITY OF FORT COLLINS - ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS C-2 CTL IT PROJECT NO. FC04902-135 (revised) L-1 B. Street grading shall be within plus or minus 1 A 0 of one foot. The civil engineer, or duly authorized representative, shall check all cut and fill areas to observe that the work is in accordance with the above limits. 12. SUPERVISION AND CONSTRUCTION STAKING Observation by the Soils Engineer shall be continuous during the placement of fill and compaction operations so that he can declare that the fill was placed in general conformance with specifications. All site visits necessary to test the placement of fill and observe compaction operations will be at the expense of the Owner. All construction staking will be provided by the Civil Engineer or his duly authorized representative. Initial and final grading staking shall be at the expense of the owner. The replacement of grade stakes through construction shall be at the expense of the contractor. 13. SEASONAL LIMITS No fill material shall be placed, spread or rolled while it is frozen, thawing, or during unfavorable weather conditions. When work is interrupted by heavy precipitation, fill operations shall not be resumed until the Soils Engineer indicates that the moisture content and density of previously placed materials are as specified. 14. NOTICE REGARDING START OF GRADING The contractor shall submit notification to the Soils Engineer and Owner advising them of the start of grading operations at least three (3) days in advance of the starting date. Notification shall also be submitted at least 3 days in advance of any resumption dates when grading operations have been stopped for any reason other than adverse weather conditions. 15. REPORTING OF FIELD DENSITY TESTS Density tests made by the Soils Engineer, as specified under "Density Tests" above, shall be submitted progressively to the Owner. Dry density, moisture content, of each test taken, and percentage compaction shall be reported for each test taken. 16. DECLARATION REGARDING COMPLETED FILL The Soils Engineer shall provide a written declaration stating that the site was filled with acceptable materials, or was placed in general accordance with the specifications. CITY OF FORT COLLINS — ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS C_3 CTL I T PROJECT NO. FC04902-135 (revised) APPENDIX D PAVEMENT CONSTRUCTION RECOMMENDATIONS SUBGRADE PREPARATION Moisture Treated Subgrade (MTS) The subgrade should be stripped of organic matter, scarified, moisture treated and compacted to the specifications stated below in Item 2. The compacted subgrade should extend at least 3 feet beyond the edge of the pavement where no edge support, such as curb and gutter, are to be constructed. 2. Sandy and gravelly soils (A-1-a, A-1-b, A-3, A-2-4, A-2-5, A-2-6, A-2-7) should be moisture conditioned to within 2 percent of optimum moisture content and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D 698, AASHTO T 99). Clayey soils (A-6, A-7-5, A-7-6) should be moisture conditioned between optimum and 3 percent above optimum moisture content and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D 698, AASHTO T 99). 3. Utility trenches and all subsequently placed fill should be properly compacted and tested prior to paving. As a minimum, fill should be compacted to 95 percent of standard Proctor maximum dry density. 4. Final grading of the subgrade should be carefully controlled so the design cross -slope is maintained and low spots in the subgrade that could trap water are eliminated. 5. Once final subgrade elevation has been compacted and tested to compliance and shaped to the required cross-section, the area should be proof -rolled using a minimum axle load of 18 kips per axle. The proof -roll should be performed while moisture contents of the subgrade are still within the recommended limits. Drying of the subgrade prior to proof -roll or paving should be avoided. 6. Areas that are observed by the Engineer that have soft spots in the subgrade, or where defection is not uniform of soft or wet subgrade shall be ripped, scarified, dried or wetted as necessary and recompacted to the requirements for the density and moisture. As an alternative, those areas may be sub -excavated and replaced with properly compacted structural backfill. Where extensively soft, yielding subgrade is encountered; we recommend a representative of our office observe the excavation. Fly Ash Stabilized Subgrade (FASS) — Double Application Utility trenches and all subsequently placed fill should be properly compacted and tested prior to subgrade preparation. As a minimum, fill should be compacted to 95 percent of standard Proctor maximum dry density. CITY OF FORT COLLINS-ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS D-1 CTL IT PROJECT NO. FC04902-135 (revised) 2. The subgrade should be stripped of organic matter and should be shaped to final line and grade. 3. Fly ash should be spread with a mechanical spreader from back of curb to back of curb for detached sidewalks or back of walk to back of walk for attached sidewalks, where applicable. The fly ash used should meet requirements specified in ASTM C 593 and C 618 for Class C fly ash. 4. Based on the water-soluble sulfate test results for this site, we recommend first treating the subgrade with 6 percent fly ash and allowing the treated subgrade to cure for a period of at least two weeks. This should allow a sufficient time for ettringite formation to occur. After the two -week period, the subgrade should be treated again with 8 percent fly ash. This will help to break up any ettringite formation that has occurred and provide a more stable base for the pavement section. 5. Fly ash and subgrade soils should be mixed, and water added until a homogeneous, uniform mixture is obtained that is within 2 percent of laboratory determined optimum moisture content in general accordance with ASTM D 558. 6. After the second application of fly ash, the fly ash/soil mixture should be compacted to at least 95% of the mixtures maximum dry density (ASTM D 558). 7. Mixing, compaction and final shaping should be completed within 2 hours of addition of water to the fly ash/soil mixture. 8. Samples of loose, blended soil/fly ash mix should be sampled by a representative of CTL Thompson, Inc. for compressive strength testing (ASTM D 1633) to determine compliance (optional) when full credit for the FASS layer is used in the pavement thickness design. 9. Batch tickets should be supplied to the owner or owner's representative with the application area for that batch to determine compliance with the recommended proportions of fly ash to soil. 10. The subgrade should be re -shaped to final line and grade. 11. The subgrade should be sealed with a pneumatic -tire roller that is sufficiently light in weight so as to not cause hairline cracking of the subgrade. 12. We recommend a minimum of 2 days curing prior to paving. The surface of the stabilized area should be kept moist during the cure period by periodic, light sprinkling if needed.. Strength gains will be slower during cooler weather. Traffic should not be permitted on the treated subgrade during the curing period.

CITY OF FORT COLLINS-ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS D-6 CTL I T PROJECT NO. FC04902-135 (revised) APPENDIX E MAINTENANCE PROGRAM MAINTENANCE RECOMMENDATIONS FOR FLEXIBLE PAVEMENTS A primary cause for deterioration of pavements is oxidative aging resulting in brittle pavements. Tire loads from traffic are necessary to "work" or knead the asphalt concrete to keep it flexible and rejuvenated. Preventive maintenance treatments will typically preserve the original or existing pavement by providing a protective seal or rejuvenating the asphalt binder to extend pavement life. 1. Annual Preventive Maintenance a. Visual pavement evaluations should be performed each spring or fall. b. Reports documenting the progress of distress should be kept current to provide information on effective times to apply preventive maintenance treatments. c. Crack sealing should be performed annually as new cracks appear. 2. 3 to 5 Year Preventive Maintenance a. The owner should budget for a preventive treatment at approximate intervals of 3 to 5 years to reduce oxidative embrittlement problems. b. Typical preventive maintenance treatments include chip seals, fog seals, slurry seals and crack sealing. 3. 5 to 10 Year Corrective Maintenance a. Corrective maintenance may be necessary, as dictated by the pavement condition, to correct rutting, cracking and structurally failed areas. b. Corrective maintenance may include full depth patching, milling and overlays. c. In order for the pavement to provide a 20-year service life, at least one major corrective overlay should be expected. CITY OF FORT COLLINS — ENGINEERING DEPARTMENT NORTH COLLEGE AVENUE AND EAST WILLOX LANE ROADWAY IMPROVEMENTS E-1 CTL I T PROJECT NO. FC04902-135 (revised) MAINTENANCE RECOMMENDATIONS FOR RIGID PAVEMENTS High traffic volumes create pavement rutting and smooth polished surfaces. Preventive maintenance treatments will typically preserve the original or existing pavement by providing a protective seal and improving skid resistance through a new wearing course. Annual Preventive Maintenance a. Visual pavement evaluations should be. performed each spring or fall. b. Reports documenting the progress of distress should be kept current to provide information of effective times to apply preventive maintenance. c. Crack sealing should be performed annually as new cracks appear. 2. 4 to 8 Year Preventive Maintenance a. The owner should budget for a preventive treatment at approximate intervals of 4 to 8 years to reduce joint deterioration. b. Typical preventive maintenance for rigid pavements includes patching, crack sealing and joint cleaning and sealing. c. Where joint sealants are missing or distressed, resealing is mandatory. 3. 15 to 20 Year Corrective Maintenance a. Corrective maintenance for rigid pavements includes patching and slab replacement to correct subgrade failures, edge damage and material failure. b.
