General: The excavation and embankment for the project work shall be finished to reasonably smooth and uniform surfaces. Variation from the subgrade plane shall not _ be more than .08 feet in soil or more than .08 feet above or .50 below in rock. Where bituminous or concrete surfacing materials are to be placed directly on the subgrade, the subgrade plane shall not vary more than 0.04 feet. Materials shall not be wasted _ without permission of the ENGINEER. Excavation operations shall be conducted so that material outside of the limits of slopes will not be disturbed. Prior to beginning grading operations in any area, all necessary clearing and grubbing in that area shall have been performed in accordance with Section 02230 of these Specifications. When the CONTRACTOR's excavating operations encounter remains of pre -historic people's dwelling sites or artifacts of historical or archaeological significance, the operations, shall be temporarily discontinued. The ENGINEER will contact archaeological authorities to determine the disposition thereof. When directed, the CONTRACTOR shall excavate the site in such a manner as to preserve the artifacts encountered and shall remove them for delivery to the custody of the proper state authorities. Such excavation will be considered and paid for as extra work. B. Excavation: 1. Unclassified: All excess suitable material excavated from the project site and not used for embankment shall be removed from the project site and become the property of the CONTRACTOR. Where material encountered Bobcat Ridge Access Road 02315-2 Excavation and Embankment Improvements June 2006 within the limit of the work is considered unsuitable for embankment (fills) on any portion of this project work, such material shall be excavated as ' directed by the ENGINEER and replaced with suitable fill material. All unsuitable excavated material from excavation consisting of any type of debris (surface or buried), excavated rock, bedrock or rocks larger than 6 inches in diameter and boulders shall be hauled from the project site and disposed of. Debris is defined as "anything that is not earth which exists at the job site". 2. Muck: Where excavation to the finished grade section results in a subgrade or slopes of unsuitable soil, the ENGINEER may require the CONTRACTOR to remove the unsuitable materials and backfill to the finished graded section with approved material. Disposal of the material shall be at the CONTRACTOR's expense. Good surface drainage shall be provided around all permanent cuts to direct surface runoff away from the cut face. 3. Rock: Unless otherwise specified, rock shall be excavated to a minimum depth of 0.5 feet below subgrade within the limits of the channel area, and the excavation shall be backfilled with material shown on the Drawings or as designated by the ENGINEER. Disposal of material and replacement with suitable approved material shall be at the CONTRACTOR's expense. C. Embankment Construction: Embankment construction shall consist of constructing all fill areas, including preparation of the areas upon which they are to be placed, and j the placing and compacting of embankment material in holes, pits and other depressions within the project area.

Bobcat Ridge Access Road 02315-3 Excavation and Embankment Improvements June 2006 On -site cohesive soils or imported soils should be placed and compacted in horizontal lifts, using equipment and procedures that will produce recommended moisture contents and densities throughout the lift and embankment height. On -site - or imported cohesive soils should be compacted within a moisture content range of 2% below, to 2% above optimum moisture content and compacted to 95% of the Maximum Standard Proctor Density (ASTM D698). When embankment is to be placed and compacted on hillsides, or when new embankment is to be compacted against existing embankments, or when embankment is built 1/2 width at a time, the slopes that are steeper than 4:1 when measured longitudinally or at right angles to the adjacent ground shall be continuously benched over those areas where it is required as the work is brought up in layers. Benching shall be well keyed and where practical a minimum of 8 feet. Each horizontal cut shall begin at the intersection of the original ground and the vertical sides of the previous cuts. Material thus cut out shall be recompacted along with the new embankment material at the CONTRACTOR'S expense. The ground surface underlying all fills shall be carefully prepared by removing all organic matter, scarification to a depth of 8 inches and recompacting to 95% of the — Maximum Standard Proctor Density (ASTM D698) at optimum moisture content + or - 2% prior to fill placement. Embankment material shall be placed in horizontal layers not exceeding 8 inches — (loose measurement) and shall be compacted to 95% of the Maximum Standard Proctor Density (ASTM D698) at optimum moisture content + or - 2%. Effective spreading equipment shall be used on each lift to obtain uniform thickness prior to compacting. As the compaction of each layer progresses, continuous leveling and l manipulating will be required to assure uniform density. For embankments which serve as berms, the downstream portion shall be "keyed" into the subsurface soils a minimum of 3 feet to enhance the stability of the slope. Materials which are removed from excavations beneath the water table may be over the optimum moisture content and will require that they be dried out prior to reusing them. — Cross hauling or other action as appropriate will be ordered when necessary to insure that the best available material is placed in critical areas of embankments, including the top 2 feet of all embankments. No additional payment will be made for cross hauling ordered by the ENGINEER. Frozen materials shall not be used in construction of embankments. — During the construction of channels, the channel bottom shall be maintained in such condition that it will be well drained at all times. — Excavation or Embankment (Fill), and Structural Backfill work either completed or in a stage of completion that is either eroded or washed away or becomes unstable _ due to either rains, snow, snow melt, channel flows or lack of proper water control shall be either removed and replaced, recompacted or reshaped as directed by the Bobcat Ridge Access Road 02315-4 Excavation and Embankment Improvements June 2006 ENGINEER and in accordance with the Drawings and Specifications at the CONTRACTOR's sole expense.

Joining Stab Joints F Immediately before joining two lengths of ductile iron pipe, the inside of the bell end, the outside of the spigot end and the rubber gasket shall be thoroughly cleaned to remove oil, grit, excess coating, and other foreign matter. The rubber gasket shall be flexed inward and properly inserted in the gasket recess of the bell socket. Caution shall be exercised to insure the correct type of gasket is used. A thin film of gasket lubricant shall be applied to either the inside face of the gasket or the spigot end of the pipe or both. The spigot end of the pipe shall be placed in the socket with care to prevent the joint from contacting the ground. The joint shall be completed by pushing the pipe home with a slow steady pressure without jerky or jolting movements. Pipe furnished without a depth mark shall be marked before assembly to assure insertion to the full depth of the joint. The spigot end of field cut pipe lengths shall be filed or ground to resemble the spigot end of such pipe as manufactured. Whenever it is desirable to deflect stab joint pipe in order to form a long radius curve, the deflection shall not exceed eighty percent (80%) of the pipe manufacturer's recommendations for maximum deflection. D. Joining Mechanical Joint Pipe Before joining mechanical joint ductile iron fittings to the ductile iron pipe, the outside of the spigot, the inside of the bell and the rubber gasket shall be thoroughly cleaned to remove oil, grit, excess coating, and other foreign matter. Normal practice is to lubricate the joint with a soap solution; however, in cold weather the joint may be assembled dry if approved by the ENGINEER. Extreme care shall be exercised in making the dry joint. The ductile iron gland shall be slipped on the spigot end of the pipe with the lip extension of the gland toward the socket, or bell end. The rubber gasket shall be placed on the spigot end with the thick edge toward the gland. The pipe shall be pushed forward until the spigot end fully penetrates the bell. The gasket shall then be pressed into place in the bell evenly around the entire joint. The gland shall be moved along the pipe into position for bolting, the bolts inserted, and the nuts screwed finger tight, then tightened with a torque limiting wrench. The torque for the various sizes of bolts shall be as follows: Pipe Size Bolt Size Range of Torque inches inches (ft._lbs.) 2-3 5/8 60 4-24 3/4 75-90 30-36 1 100-120 42-48 1 1/4 120-150 Bobcat Ridge Access Road 02615-5 Ductile Iron Pipe Improvements June 2006 Nuts spaced 180 degrees apart shall be tightened alternately in order to produce an equal pressure on all parts of the gland. Whenever it is desirable to deflect mechanical joint pipe in order to form a long radius curve, the deflection shall not exceed eighty percent (80%) of the pipe manufacturer's recommendations for maximum deflection. E. Flexible Coupled Joint When installing flexible steel couplings, care shall be taken that the connecting pipe ends, couplings and gaskets are clean and free of all dirt and foreign matter with special attention being given to the contact surfaces of the, pipe, gaskets and couplings. These couplings shall be assembled and installed in conformity with the recommendations and instructions of the coupling manufacturer. Wrenches used in bolting couplings shall be of a type and size recommended by the coupling manufacturer. Coupling bolts shall be tightened so as to secure a uniform annular space between the follower rings and the body of the pipe and all bolts tightened approximately the same amount. Diametrically opposite nuts shall be tightened progressively and evenly. Final tightening shall be done with a torque limiting wrench set for the torque recommended by the coupling manufacturer. F. Flanged Joint _ Before the joint is assembled, the flange faces shall be thoroughly cleaned of all foreign material with a power wire brush. The gasket shall be centered and the connecting flanges drawn up watertight without unnecessary stressing of the _ flanges. All bolts shall be tightened in a progressive diametrically opposite sequence using torque wrenches at settings recommended by the manufacturer (75 lb. min.). Only compressed asbestos sheet gaskets with a rubber compound binder shall be — used. Where steel flanges are connected to ductile iron flanges, an insulating connection shall be provided. G. Polyethylene Wrap Ductile iron pipe and fittings shall be polyethylene encased (cross -laminated HDPE) in accordance with A.W.W.A. Standard C-105, "Polyethylene Encasement for Ductile Iron Piping for Water and Other Liquids," and as detailed on the Drawings. H. Cutting and Fitting The CONTRACTOR shall make all pipe cuts required to conform to location, line and grade. All cuts on ductile iron pipe shall be made by the use of pipe cutters or pipe saws. All cuts shall be straight and true. 3.02 PIPE INSTALLATION - GENERAL A.- Underground Interference _ Bobcat Ridge Access Road 02615-6 Ductile Iron Pipe Improvements ^ June 2006 A reasonable attempt has been made to locate and identify the underground interferences to be encountered. However, it shall be the responsibility of the CONTRACTOR to verify the locations shown on the Drawings. It shall also be the responsibility of the CONTRACTOR to locate any interference not shown on the Drawings. The CONTRACTOR shall exercise care when working in order to protect all underground interference and shall be fully responsible for any and all damage caused by his operations. B. Pipe Alignment and Grade In laying pipe, maximum tolerance is permitted to set line within +/-0.3 foot and grade within +/-0.1 foot. Fittings, valves and hydrants shall be installed at the specified locations and elevations, unless written permission to deviate is obtained from the ENGINEER. When laying pipe in curves, the intent is to lay to the alignment. The pipe shall be kept in alignment by deflecting joints, using short lengths or bends. Any changes in alignment and grade must be authorized by the ENGINEER and shall be accomplished by the installation of additional fittings, or "breaking" of joints. C. Deviation from Alignment and Grade Occasioned by Other Structures Whenever obstructions, not shown on the Drawings, interfere to such an extent that an alteration in the Drawings is required, the ENGINEER shall have the authority to determine the best method of correction. He may change the Drawings and order a deviation from line and grade, or he may instruct the OWNER to arrange with the CONTRACTOR to arrange with the owners of the structure for its removal, relocation or reconstruction, as best fits the economic and field conditions. D. Temporary Bulkhead Whenever the pipe is left unattended, temporary plugs shall be installed at all openings. Temporary plugs shall be watertight and of such design as to prevent children, animals, or debris from entering the pipe. If water accumulates in the trench, the plugs shall remain in place until the trench is dry. E. Connection of Pipelines of Dissimilar Metals Insulated couplings or insulated flange kits shall be used when joining pipes of dissimilar metal either above or below grade. F. Pipeline Marker or Detection Tape Polyethylene warning tape shall be installed approximately 2 feet below the ground surface, centered over all buried waterlines.

The installing Contractor shall certify that the installation conforms to the requirements of this specification and furnish a written guarantee protecting the landowner against defective materials and workmanship for a period of less not than 1 year. The guarantee will identify manufacturer of pipe and pipe markings. PART 3 EXECUTION 3.01 TRENCH CONSTRUCTION A. Trench width at any point below the top of the pipe should be only wide enough to permit the pipe to be easily placed and joined and to allow the initial backfill material to be uniformly placed under the haunches and sides of the pipe. The maximum trench width shall be 36 inches greater than the diameter of the pipe. The minimum trench width shall not be less than one pipe diameter plus 18 inches, unless the trench is precision excavated with a semicircular bottom that closely fits the pipe and the width does not exceed the outside diameter of the pipe by more than 10 percent. Trench banks that are more than 5 feet high shall be shored or loped. Refer to Figure 1 for typical trench details. B. Where rock, hardpan, cobbles or other hard material which might prevent the pipe from being uniformly supported is encountered in the bottom of the trench, the trench shall be undercut a minimum of four inches below final grade. The over cut area of the trench will then be filled with sand or fine-grained soil. 3.02 BEDDING A. The pipe shall be firmly and uniformly bedded throughout its entire length. Bedding material shall be placed and spread in uniform layers and in such a manner as to fill the trench so there are no unfilled spaces below the pipe. For pipe with bell joints, holes shall be dug in the bedding at the bells to permit the body of the pipe to be in contact with the bedding along its entire length. Blocking or mounding shall not be used to bring the pipe up to final grade. 3.03 PIPE INSTALLATION A. Pipe shall be the diameter, length, material, and pressure class as specified on the drawings. B. The pipe shall not be dropped into the trench or handled in a manner to cause damage. Individual joints of pipe shall be inspected and any damaged pipe shall be removed and replaced. The pipe will be allowed to come within a few degrees of the temperature it will have after it is completely backfilled before placing fill other than that needed for shading or before connecting the pipe to other facilities. C. Hand, mechanical or water packing are optional methods for placing and compacting pipe backfill. Bobcat Ridge Access Road 02620-3 Low Pressure Plastic Pipe Improvements June 2006 3.04 INITIAL BACKFILL A. Pipe with a pressure rating of less than 50 psi shall be filled with water prior to placement of backfill materials and maintained near the design working pressure - during the backfilling operations. The initial backfill material shall be soil or sand that is free from rocks, gravels, frozen materials larger than 1 inch or earth clods greater than 2 inches in diameter. This may be the on site trench excavated materials as long as any unsuitable materials are removed. The initial backfill materials shall be placed in a manner as not to displace, deform or damage the pipe. _ B. When backfilling is done by hand or mechanical means the initial fill shall be compacted firmly around and above the pipe to achieve a soil density equal or — greater than the density of the undisturbed side walls of the trench. The thickness of individual lifts prior to compaction shall not exceed 6 inches. C. When water packing is used, the pipe shall be filled with water. The initial backfill, before wetting, shall be of sufficient depth to ensure complete coverage of the pipe with backfill after consolidation has taken place. Water packing shall be accomplished by adding water to diked reaches of the trench in such quantity as to thoroughly saturate the initial backfill. After the backfill is saturated, the fill shall be consolidated by rodding or with a vibrator. The wetted fill shall be allowed to dry until firm before completing the final backfill. The pipeline shall remain full of water until after the final backfill is placed. 3.05 FINAL BACKFILL A. The final backfill material shall be free of rocks, frozen clods or other debris larger than linch in diameter within 6 inches of the pipe and 6 inches in particle size for the remaining portion of the final backfill unless otherwise specified on the drawings. The material shall be placed and spread in approximately uniform layers — so there are no unfilled spaces in the backfill. Rolling equipment shall not be used until a minimum of 18 inches of compacted backfill material has been placed over the top of the pipe and then only on pipe having a wall thickness greater than that of SDR-41. Final backfill may be mounded over the top of the trench above ground level, but in no case shall the final backfill be lower than the natural ground along the top of the trench. _ B. All special backfilling requirements of the pipe manufacturer shall be followed. 3.06 COVER r A. The minimum depth for backfill over the top of the pipe shall be 30 inches. The — maximum depth for backfill is 4 feet. B. At low places on the ground surface or at locations where it is shallow to rock, extra fill may be placed over the pipeline to provide the minimum depth of cover. In such cases, the top width of the fill shall be no less than 10 feet and the side slopes no steeper than 6 horizontal to 1 vertical. Bobcat Ridge Access Road 02620-4 Low Pressure Plastic Pipe Improvements June 2006 C. Vertical alignment of pipe shall be uniform and such as to maintain the cover requirements unless otherwise noted on the drawings. If irregular grades are j required, thrust blocks, air releases, drains and other appurtenances as needed shall be installed. 3.07 THRUST BLOCKS A. Thrust blocks shall be formed against a solid trench wall. They shall be of the minimum size and materials as specified on the drawings. 3.08 JOINTS AND CONNECTIONS A. All joints and connections shall be constructed to withstand the design working pressure for the pipeline without leakage and shall leave the inside of the pipeline free of any obstruction which could reduce the pipe capacity below design requirements, except that insert fittings for joining PE pipe are permitted. B. All fittings, such as couplers, reducers, bends, tees and endives shall be made of material that is recommended for use with the type of pipe specified and shall be installed in accordance with the recommendations of the pipe manufacturer. Fittings made of steel or other materials susceptible to corrosion shall (1) be wrapped with plastic tape meeting the requirements of AWWA C 209 for Type I or II tape, or (2) coated with coal -tar epoxy paint (Kippers-Bitumastic No. 300-M is an approved off the shelf product), or (3) painted with one coat of urethane primer applied at a rate of 2 to 3 mils thick and two or more coats of gloss or semi -gloss Alkyd Enamel to provide a minimum thickness of 6 mils or (4) coated with epoxy paint in accordance with the Steel Structures Council (SSPC) Paint Specification # 16. C. Pipelines with solvent welded joints shall have expansion -contraction couplers as indicated on the drawings. Couplers shall have a minimum length of 14 inches. D.

EQUIPMENT A. General: Equipment shall be capable of legally performing the work as described in this Specification. Equipment that is inadequate to obtain the results specified shall be replaced or supplemented as required to meet the requirements of this Specification. _ Any equipment that is used in an improper manner may be cause for rejection of the work if in the opinion of the ENGINEER the work fails to meet the requirements of this specification. Equipment used for compaction shall be the rolling type, vibratory type, or combination of both types, and shall be of sufficient capacity to meet the compaction requirements herein. PART 3 EXECUTION 3.01 PREPARATION OF FOUNDATION A. The foundation shall be considered to be the finished earth subgrade, subbase course, or base course, as the case may be, upon which any subbase, base or surface course is to be constructed. Preparation of foundation for construction of a subbase, base, or surface course shall consist of the work necessary to restore, correct, strengthen or prepare the foundation to a condition suitable for applying and supporting the intended course. For aggregate base course roads and parking areas, the top six -inches of topsoil shall be stripped within the area to be aggregate surfaced. Following stripping of the Bobcat Ridge Access Road 02710-2 Aggregate Base Course Improvements June 2006 topsoil, the upper 12 inches of the subgrade shall be scarified and compacted to a minimum of 95% of the Maximum Standard Proctor Density (ASTM D698). On - site material may be used as accepted by the ENGINEER, for compacted fill for the aggregate base course. Fill shall be placed within 2% of optimum moisture content and compacted to a minimum of 95% of the Maximum Standard Proctor Density (ASTM D698). Aggregate base course used as a foundation for pavements shall be placed on the subgrade within two percent of optimum moisture and compacted to a minimum of 95% of the Maximum Standard Proctor Density (ASTM D698). The top six inches of topsoil shall be stripped within the area to be aggregate surfaced. Following stripping of the topsoil, the upper 12 inches of the subgrade shall be scarified and compacted to a minimum of 95% of the Maximum Standard Proctor Density (ASTM D698). On -site material may be used, as accepted by the ENGINEER, for compacted fill for the aggregate base course. Fill shall be placed within 2% of optimum moisture content .and compacted to a minimum of 95% of the Maximum Standard Proctor Density (ASTM D698). Deviations in aggregate base course under pavements of more than 1/4 inch in 10 feet, measured with a 10-foot straight edge, shall be corrected prior to pavement construction. The foundation shall be prepared and constructed such that it will have a uniform density throughout. It shall be brought to the required alignment and cross section with equipment and methods adapted for the purpose. Upon completion of the shaping and compacting operations, the foundation shall be smooth, at the required density, and at the proper elevation and contour to receive the aggregate base course. After the specified compaction has been obtained, the subgrade under the curb, gutter, sidewalk and pavement shall be proof -rolled with a heavily loaded rubber tire roller, fully loaded water truck, or other approved equipment. Those areas which produce a rut depth of over '/z inch or which crack the subgrade after pumping and rebounding shall be ripped, scarified, wetted or dried if necessary, and recompacted to the requirements for density and moisture at the CONTRACTOR'S expense. Where unsuitable material is encountered, the ENGINEER may require the CONTRACTOR to remove the unsuitable materials and backfill to the finished grade with approved material. The completed subgrade shall be proof -rolled again after placement of approved material. Unless otherwise provided, all holes, ruts and other depressions in the foundation shall be filled with materials similar to those existing in the foundation. High places shall be excavated and removed to the required lines, grade and section. Base course material shall not be placed on a foundation that is soft, spongy, or one that is covered by ice or snow. Base course shall not be placed on a dry or dusty foundation where the existing condition would cause rapid dissipation of moisture from the base course material and hinder or preclude its proper compaction. Dry foundations shall have water applied and reworked and compacted as necessary. The ENGINEER shall direct the CONTRACTOR to make minor adjustments in the finish grade from that shown in the Drawings as may be necessary or desirable to maintain the characteristics of a stabilized foundation by minimizing the amount of cutting into or filling. Bobcat Ridge Access Road 02710-3 Aggregate Base Course Improvements June 2006 3.02 EARTH SUBGRADE A. When the foundation is an earth subgrade it shall be prepared by removing all vegetation, excavating and removing materials, filling depressions, scarifying, shaping, smoothing and compacting to meet the required grade, section and density. Stones over six inches in greatest dimension shall be removed. 3.03 PLACEMENT A. The aggregate base course shall be constructed to the width and section shown in the Drawings. If the required compacted depth of base coarse exceeds six inches, the base shall be constructed in two or more layers of approximate equal thickness. The maximum compacted thickness of any one layer shall not exceed six inches. Each layer shall be constructed as far in advance of the succeeding layer as the ENGINEER may direct. The work shall, in general, proceed from the point on the project nearest the point of supply of the aggregate in order that the hauling equipment may travel over the previously placed material, and the hauling equipment shall be routed as uniformly as possible over all portions of the previously constructed courses or layers of the base course. The material shall be deposited on the soil foundation, or previously placed layer in a manner to minimize segregation and to facilitate spreading to a uniform layer of — the required section. In the event that blending of materials is necessary to provide required gradation and properties of the material, and is done in the roadway, the same shall be accomplished by mixing the aggregate and blending material by means of blade graders, discs, harrows or other equipment to effect a uniform distribution and gradation throughout the finished mixture. Excessive mixing and grading that l , will cause segregation between the coarse and fine materials is prohibited. l 3.04 COMPACTION A. After a layer or course has been placed and spread to the required thickness, width and contour, it shall be compacted. If the material is too dry to readily attain the required density, it shall be uniformly moistened to the degree necessary during compaction operations for proper compaction. — B. Compaction of each layer shall continue until the required density of Section 3.01 is reached. The surface of each layer shall be maintained during compaction operations in such a manner that a uniform texture is produced and aggregates firmly keyed. All areas where proper compaction is not obtainable due to segregation of materials, excess fines, or other deficiencies in the aggregate, shall be reworked as necessary or the material removed and replaced with aggregates that will meet this specification. The surface of each layer shall be kept true and smooth at all times. 3.05 MIXING A.

Preparation of Asphalt Cement: The asphalt cement shall be heated at the paving plant to a temperature not exceeding 325T. The penetration of the asphalt cement _ shall be maintained within the limits of penetration specified through the period of US. B. Preparation of Mineral Aggregates: The mineral aggregates shall be dried and heated -' at the paving plant so that when delivered to the mixer, they shall be at as low a temperature as is consistent with proper mixing and laying, and in no case to exceed 350°F. They may be fed simultaneously into the same drier but in all cases, immediately after heating, they shall be screened into three or more bins. The screen l sizes shall be approved by the ENGINEER prior to the start of construction. C. Preparation and Composition of the Mixture: Each size of hot aggregate, the mineral filler and the asphalt cement shall be measured separately and accurately to the proportions in which they are to be mixed. After the hot aggregate and mineral filler have been charged into the mixer and thoroughly mixed as directed by the ENGINEER, the asphalt cement shall be added and the mixing continued for a period of at least 20 seconds, or longer if necessary, to produce a homogeneous mixture, in which all particles of the mineral aggregates are coated uniformly. D. Paving Plant Inspection: For the verification of weights or proportions and character of materials and determination of temperatures used in the preparation of the mixture, the ENGINEER or his authorized representative shall have access at any time to all parts of the paving plant. PART 3 EXECUTION 3.01 SURFACE PREPARATION A. All final pavement cuts shall be made in straight lines using saw cut. Initial pavement cuts may be made using wheel cut or other suitable method. _ B. Prior to placing the prime coat, the base course shall be thoroughly cleaned. Loose material shall be removed from the existing surface as directed by the ENGINEER. Bobcat Ridge Access Road 02740-6 Flexible Pavement Improvements June 2006 3.02 PRIME COAT A. All previously prepared bases or existing surface shall be primed with a cationic emulsified asphalt in accordance with the requirements of these Specifications or as directed by the ENGINEER. The prime coat shall be placed by means of an approved pressure distributor. Before application, the asphaltic oil shall be heated as directed by the ENGINEER. However, it shall not be heated to more than 180°F. In general, the rate of application shall be from 0.25 to 0.35 gallons per square yard as directed by the ENGINEER. The prime coat shall be carefully applied, particularly around curbs and sidewalks. If excessive amounts of curb, sidewalks, or other structures are sprayed with asphaltic oil, they shall be cleaned as directed by the ENGINEER at the CONTRACTOR's expense. All vertical contact faces shall be primed by painting with cationic emulsified asphaltic oil. 3.03 ASPHALTIC CONCRETE SURFACE A. Transportation of Mixture: The mixture shall be transported from the paving plant to the work in vehicles equipped with tight metal compartments previously cleaned of all foreign materials. When directed by the ENGINEER, the compartments shall be sufficiently insulated and each load shall be covered with canvas or other suitable materials of sufficient size to protect it from weather conditions. The inside surface of all vehicle compartments used for hauling mixture must be lightly lubricated with a tin oil or soap solution just before loading, but excess lubricant will not be permitted. No load shall be sent out so late in the day as to interfere with spreading and compacting the mixture during daylight unless artificial light, satisfactory o the ENGINEER, is provided. B. General Conditions: The mixture shall be laid only when the base is dry and only when weather conditions are suitable. The mixture shall be laid when atmospheric temperatures are consistent with the placement temperature limitations as outlined on page 02740-10. Asphalt shall not be placed when frost exists in the subgrade. Any material laid shall be rolled with pneumatic rollers in addition to the specified rolling, as directed by the ENGINEER. C. Placing Asphalt Mixture: If traffic is allowed to use the prepared subgrade or sub- base, the subgrade or sub -base shall be checked and corrected as needed immediately ahead of placing bituminous materials. Prior to placement of the bituminous surface, the base shall be cleaned of all dirt or other foreign matter. When the new pavement abuts the old pavement; the CONTRACTOR shall cut the old pavement as directed by the ENGINEER and paint the edge of the pavement with a tack coat.

The asphaltic pavement shall have a density of ninety-five percent (95%) of a representative laboratory compacted specimen by the Hveem method as tested in accordance with ASTM Method 2950-132 and ASTM D 2726-83. While the surface is being compacted and finished, the CONTRACTOR shall carefully trim the outside edges of the pavement to the proper alignment. _ Unless otherwise permitted by the ENGINEER, the mixture shall be spread by means of a mechanical self -powered paver, capable of spreading the mixture true to the line, grade, and crown set by the ENGINEER. Pavers shall be equipped with hoppers and distributing screws of the reversing type to place the mixture evenly in front of adjustable screeds. The mixture shall be dumped in the center of the hoppers and care exercised to avoid overloading and spilling over of the mixture upon the base. Pavers shall operate when laying mixtures at such speed between 10 feet and 20 feet per minute, as may be decided by the ENGINEER. Pavers shall be equipped with a -quick and efficient steering device and shall have ^ forward and reverse speeds of not less than 100 feet per minute. Unless operating on fixed side forms, pavers shall employ mechanical devices such _ as equalizing runners, straightedge runners, evener arms, or other compensating devices to adjust the grade and confine the edges of the mixture to true lines within the use of stationary side forms. The pavers shall be capable of spreading the mixtures, without segregation, in thickness of from ''/z inch to 3 inches, to a maximum width of 10 feet in increments of 1 foot or less and to a minimum width of 8 feet. They shall be equipped with blending or joint leveling devices for smoothing and adjusting all longitudinal joints between adjacent strips of courses of the same thickness. When asphalt concrete pavement thickness in excess of 2 inches is called for, they _ shall be laid in separate courses of not less than 1 inch or more than 2 inches or as directed by the ENGINEER. Bobcat Ridge Access Road 02740-8 Flexible Pavement Improvements June 2006 The term "screed" includes a "strike -off' device operating by cutting, crawling, or other practical action which is effective on the mixture at a workable temperature without tearing, shoving, or gouging and which produces a finished surface of the evenness and texture specified. The screed shall be adjustable as to level and shall have an indicating level attached. Longitudinal and transverse joints shall be made in a careful manner. Well bonded and sealed joints are required. If necessary to obtain this result, joints shall be painted with cationic emulsified asphaltic cement. In making the joint along any adjoining edges such as curb, gutter, or an adjoining pavement and after the hot mixture is placed by the finished machine, just enough of the hot material shall be carried back to fill any space left open. This joint shall be properly "set" up with the back of rake at proper height and level to receive the maximum compression under rolling. The work of "setting up" this joint shall be performed always by competent workmen who are capable of making correct, clean, and neat joints. Immediately after any course is screeded, and before roller compaction is started, the surface shall be checked, any inequalities adjusted, all fat, sandy accumulations from the screed removed by a rake or hoe, and all fat spots in any course removed and replaced with satisfactory material. Irregularities in alignment and grade along the outside edge shall also be corrected by the addition or removal of mixture before the edge is rolled. In narrow, deep, or irregular sections, intersections, turnouts, or driveways where it is impractical to spread and finish the mixtures by machine methods, the l CONTRACTOR may used approved spreading equipment or acceptable hand _) methods as directed by the ENGINEER. When the mixture is to be spread by hand, upon arrival on the work it shall be dumped upon a steel dump board outside the area on which it is to be spread. Immediately thereafter it shall be distributed into place by means of hot shovels and spread with hot rakes in a loose layer of uniform density and correct depth. Tines of the rakes shall not be less than inch longer than the loose depth of the mixture, and spaces between tines shall not be less than the maximum diameter of aggregate particle except that in no case should the spaces be less than 1 inch. Loads shall not be dumped any faster than can be properly handled by the shovelers. The shovelers shall not distribute the dumped load faster than it can be properly handled by the rakers. The rakers will not be permitted to stand in the hot mixture while raking it, except where necessary to correct errors in the first raking. The raking must be carefully and skillfully done in such a manner that after the first passage of the roller over the raked mixture, a minimum amount of back patching will be required. Placing mixtures shall be as continuous as possible and the roller shall pass over the unprotected edge of the freshly laid mixture only when the laying of this course is to be discontinued for such intervals of time as to permit the mixture to become chilled. D. Joints: Joints between old and new pavements, or between successive days' work, shall be carefully made in such a manner as to insure a thorough and continuous bond Bobcat Ridge Access Road 02740-9 Flexible Pavement Improvements June 2006 between the old and new surfaces. The edge of the previously laid course shall be cut back to its full depth so as to expose a fresh surface, after which the hot surface mixture shall be placed in contact with it and raked to a proper depth and grade. Hot smoothers or tampers shall be carefully used in such a manner as to heat up the old pavement sufficiently (without burning it) to insure a proper bond. Before placing mixture against them, all contact surfaces of curbs, gutters, headers, manholes, etc., shall be painted with a thin uniform coating of cationic emulsified asphaltic cement. — E. Compaction of the Mixture: After spreading, the mixture shall be thoroughly and uniformly compressed by a power -driven roller or rollers, weighing not less than 8 tons, as soon after being spread as it will bear the roller without undue displacement. Delays in rolling freshly spread mixture will not be tolerated. Rolling shall start longitudinally at the sides and shall proceed toward the center of the pavement ^ overlapping on successive trips by at least '/2 the width of a rear wheel. Alternate trips of the roller shall be of slightly different lengths. If the width of the pavement permits, it shall, in addition, be rolled at right angles to the center line. The speed of the roller shall not exceed 3 nines per hour and shall, at all times, be slow enough to avoid displacements of the hot mixture, and any displacement occurring as a result of reversing the direction of the roller, or from any other cause, shall at once be corrected by the use of rakes and of fresh mixture where required. Rolling shall proceed continuously until all roller marks are eliminated. To prevent adhesion of the mixture to the roller, the wheels shall be kept properly moistened, but excess water will not be permitted. The rollers shall be in good condition, capable of reversing without back -lash and _ shall weight not less than 200 pounds to the inch of tread. They shall be operated by competent and experienced rollermen and must be kept in continuous operation as nearly as practicable in such a manner that all parts of the pavements shall receive ^ substantially equal compression. Along curbs, headers, manholes, and similar structures, and all places not accessible to the roller, thorough compactions must be secured by means of hot tampers and at all contacts of this character, the joints between these structures and the surface mixture must be effectively sealed. ^ The course, after final compaction, shall conform to the following requirements: It shall be smooth and true to the established crown and grade. It shall have the — average thickness specified and shall at no point vary more than '/a -inch from the thickness required by the OWNER or the Contract Documents. Any low or defective places shall immediately be remedied by cutting out the course at such spots and replacing it with fresh, hot mixture which shall be immediately compacted to conform with the surrounding area and shall be free from depressions exceeding '/c- inch as measured with a 10-foot straightedge paralleling the centerline of the roadway. After final compaction, the finished surface course shall at no point have a density less than 95% of the maximum density possible to be obtained in a voidless pavement composed of the same materials in like proportions. Density shall be determined from specimens cut from the finished pavement as directed by the ENGINEER. Bobcat Ridge Access Road 02740-10 Flexible Pavement Improvements June 2006 3.04 ASPHALT PATCHING -� A. Grading SG shall be placed in the bottom of the patches and shall be left one and - one-half (1/2) to two (2) inches below the existing street surface to allow the patch to be "topped" with a surface course material. The "topping" material shall be Hot Bituminous Pavement Grading SX for residential streets, and Grading S for arterials and collectors. Hot Bituminous Pavement used for "topping" material will be measured and paid for at the Contract Unit Price for Patching.

No concrete shall be placed until all formwork, reinforcement, installation of parts to be embedded, bracing of forms, and preparation of surfaces involved in the placing have been reviewed by the ENGINEER. No concrete shall be placed in water except with the written permission of the ENGINEER. _ All surfaces of forms and embedded materials that have become encrusted with dried mortar or grout from concrete previously placed shall be cleaned of all such mortar or grout before the surrounding or adjacent concrete is placed. Immediately before placing concrete, all surfaces upon or against which the concrete is to be placed shall be free from standing water, mud, debris or loose materials. The surfaces of absorptive materials against or upon which concrete is to be placed shall be moistened thoroughly so that moisture will not be drawn from the freshly placed concrete. The concrete shall be placed by equipment that will prevent segregation or loss of ingredients. The stream of concrete shall not be allowed to separate by permitting it to fall freely over rods, spacers or other embedded materials. No wetting of concrete surfaces during slab finishing operations shall be permitted. Further, no concrete finishing operation shall be permitted while there is water on the surface of slabs and other flatwork. Unless otherwise called out in these Specifications or shown in the Drawings, the placement lift depth of concrete in walls shall be limited to two feet or less to minimize surface defects such as air voids that can form on concrete surfaces. Lift depths will be limited to one foot if, in the opinion of the ENGINEER, the quality of the finish is unacceptable at the 2-foot lift depth. 3.03 CONSOLIDATION All concrete shall be thoroughly consolidated with internal vibrators as recommended in ACI 309 immediately after deposition. The concrete shall be thoroughly worked around the reinforcing steel, around embedded items and into corners of forms. Vibration shall be supplemented by spading, rodding or forking to eliminate all honeycomb and voids around embedded items. The vibrator shall be inserted vertically, allowing it to penetrate rapidly to the bottom of the lift and at least six inches into the previous lift.

The vibrator shall be pulled up at a rate of about three inches per second. The vibrator shall be inserted so that the fields of action overlap. The field of action is approximately eight times the vibrator's head diameter. Thus for a 2 1/2 inch diameter vibrator, the spacing of each insertion will be approximately 20 inches. Vibration shall be stopped when the concrete surface takes a sheen and large air bubbles no longer escape. Do not use a vibrator to move concrete horizontally. 3.04 OPENINGS AND INSERTS Pipe sleeves, inserts for pipe connections, anchors and forms for' pipe holes must be accurately placed and securely fastened to the forms in such a manner that the placing of concrete will not alter their alignment or location. In the event that openings are inadvertently omitted or improperly placed, the ENGINEER may require the concrete to be cored at the proper location. Filling of improperly placed openings shall be done with expansive grout or dry pack or mortar applied with an accepted epoxy adhesive. The surfaces of the opening shall be roughened prior to filling. 3.05 EMBEDDED ITEMS At the time of concrete placement, embedded items should be clean and free from mud, oil and other coatings that may adversely affect bonding capacity. Aluminum embedments shall be coated with a bituminous material to prevent electrolytic action between the embedded item and reinforcing steel that results in concrete deterioration. Embedment items shall be accurately placed and securely fastened to the forms in such a manner that the placing of concrete will not alter their alignment or location. Contact between embedded items and reinforcing steel or tendon ducts is unacceptable and is not permitted. 3.06 CONSTRUCTION JOINTS The location of all construction joints will be subject to the acceptance of the ENGINEER. The surface of all construction joints shall be thoroughly cleaned and all laitance and standing water removed. Clean aggregate shall be exposed by abrasive blast cleaning. Wire brushing and air water jets may be used while concrete is fresh provided results are equal to abrasive blast cleaning. Construction joints shall be keyed at right angle to the direction of shear. Except where otherwise shown on the Drawings, keyways shall be at least 1-1/2" in depth over at least 25% of the area of the section. 3.07 EVAPORATIVE RETARDANT The use of an evaporative retardant is required to assist in proper placement of concrete. See Section 03390. When an evaporative retardant is used, it shall be applied two times: after screeding and after the first floating operation. The retardant should be applied at a rate of one gallon of sprayable solution per 200 - 400 square feet by spraying with an industrial type sprayer. If the nozzle of the sprayer becomes plugged, the CONTRACTOR shall clean, or replace, the nozzle. Under no circumstances shall the retardant be used except by spraying a Bobcat Ridge Access Road 03310-9 Structural Concrete Improvements June 2006 mist with a nozzle. The retardant shall be applied in strict conformance with the manufacturer's recommendations and precautions. In no case shall the retardant be used as a finishing agent.

FC03705•125 SCOPE This report presents the results of our soils and foundation investigation for the proposed roadway improvements on County Road 32C. The section of roadway covered in this report begins at the intersection with County Road 27 and extends west to the Bobcat Ridge Natural Area. A graphical depiction of the project limits is . presented in Figure 1. Our investigation was performed to identify the subsurface conditions along the roadway alignment in areas of planned culverts, embankments and water control structures. Our report includes a description of the subsurface conditions found in our borings; summaries of the results of our laboratory tests and our recommendations for foundations, geotechnical design and construction criteria. We prepared this report from data developed during our field and laboratory investigations and our experience. A summary of our findings and conclusions are presented below. SUMMARY OF CONCLUSIONS 1.. The roadway typically resides on mixed alluvial soils resulting from the historical erosion and deposition by an adjacent stream waterfeature. The . alluvial deposits were primarily loose to dense, sands and gravels with small amounts of silts and clays. The alluvial soils are underlain by very hard sandstone bedrock that crops out along both sides of the roadway. Twelve of the eighteen borings drilled terminated due to, practical auger refusal in this very hard bedrock. 2. Groundwater, where encountered, was typically 6 to 7 feet below the existing ground surface. Excavations deeper than 4 feet are likely to encounter groundwater or high moisture conditions. The stream water feature contained water during our site visit. Construction will likely require temporary conveyance of stream flows to maintain dry excavation areas. 3. Typical shallow foundations appear appropriate for box culvert and retaining wall design. 4. The soils in the area of the alternate conveyance are typically sands and gravels to a depth of approximately 6 to 9 feet that can be excavated with CITY OF FORT COLLINS - 1.

ReporWR11FC03705-125 Bobcat Ridge S&F.doc conventional equipment. Excavations extending into the bedrock may require specialized equipment or methods. 5. Roadway embankments are low and are not anticipated to exhibit settlement or stability problems. SITE CONDITIONS The existing County Road 32C is gravel surface, two-lane, rural roadway that follows a flowing tributary to Buckhorn Creek that passes through a ravine in the foothills. The stream water feature alternates sides of the roadway, passing beneath the roadway by means of metal culverts. The roadway gradually gains elevation toward the west and is mostly bordered by steep slopes and rock outcrops or the water feature. Areas nearby the roadway are vegetated with natural grasses, shrubs and trees. PROPOSED CONSTRUCTION The proposed roadway improvement locations are shown on Figure 1. The culvert locations at approximately Station 31+50 and Station 19+00 are to be replaced with box culverts. The flume at approximately Station 31+50 is to be replaced with an inverted siphon and the roadway elevation will be raised approximately 5 feet. A retaining wall is expected from Station 28+00 to 32+50 to support the roadway. The roadway from Station 6+00 to 16+00 will be raised approximately 2 feet. To eliminate the need for upgrading the culverts at Station 26+50 and 28+00, an "alternate conveyance" channel is planned for the south side of the road from Station 24+75 to 28+75 to carry storm event flows that exceed the capacity of the existing culverts. INVESTIGATION _ The field investigation for the proposed roadway improvements included drilling 18 exploratory borings at locations along the roadway near the anticipated improvements. The borings were drilled to depths ranging from 5 feet to 17 feet using CITY OF FORT COLLINS 2 BOBCAT RIDGE AND CR 32C IMPROVEMENTS CTL I T PROJECT NO.

ReporWR11FC03705-125 Bobcat Ridge S&F.doc 7 The alluvial soils are underlain by very hard sandstone bedrock that crops out along both sides of the roadway. Twelve of the eighteen boring performed terminated at depths of 4 feet to 17 feet below ground surface due to practical auger refusal in this very hard bedrock. The sandstone bedrock was observed to be medium hard to very hard, moist, and reddish brown to gray in color. Two samples of marginally weathered sandstone were recovered with sufficient quality for laboratory testing. Our laboratory testing indicated natural densities of 113 to 115 pounds per cubic foot and exhibited almost nil swell to slight consolidation when wetted. BOX CULVERTS We have assumed that excavations for the box culverts and inverted siphon will be approximately 3 to 5 feet below the existing roadway surface. Our borings indicate the excavation will be into the gravels and sands. Bedrock depths in the area of Station 31+50 appear to range from 13 to 17 feet below the existing roadway surface. Bedrock depths in the area of Station 19+00 appear to be approximately 7 feet below the existing roadway surface. Large sandstone outcrops are immediately adjacent to the roadway in these areas. We expect the bedrock surface to be steeply dipping underground. Depending on the width of the excavation, this bedrock maybe encountered. If bedrock is encountered in the excavation, we.recommend that sufficient bedrock be removed and replaced with structural fill to provide a minimum 3-foot separation from the bottom of the box culvertto minimize the risk of differential settlement. In. addition, enough bedrock should be removed from alongside the proposed box culvert to allow sufficient access for compaction equipment. We understand that the culvert will be pre -cast, reinforced concrete box sections. In our opinion, the bearing capacity of the strata at the foundation elevation of the box is at least 2,000 psf and the modulus of subgrade reaction is of the order of 600 pci.

ReportslR11FC03705-125 Bobcat Ridge S&F.doc IF The box culvert will be rigid, therefore; the sides should be designed for an "at rest" equivalent fluid density as provided in Figure 11 of this report. If wingwall structures are necessary, wingwalls that are separate from the box culvert would be free to rotate sufficiently to mobilize the strength of the backfill and can be designed for the "active" earth pressure. If the walls are connected to the box and cannot rotate, they should be designed for the "at rest' equivalent fluid density. The equivalent fluid density values provided in Figure 5 do not include an allowance for hydrostatic pressure. The unbalanced hydrostatic pressure behind the culvert walls and wingwalls caused by differential water levels across the wall can be relieved by providing a drain behind the walls or weep holes through the wall. Backfili can be constructed using soils from the required excavation that are free of debris, organic material and are less than 6 inches in diameter. Backfill beside the box culvert and behind and in front of the retaining walls should be placed in thin lifts, 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). RETAINING WALL We understand that the wall is planned as a cast -in -place, reinforced concrete wall founded with footings. We have assumed that excavations for the retaining wall to be approximately 4 to 6 feet below the existing roadway surface. Our borings indicate the excavation will mostly be into the gravels and sands. Bedrock depths west of the Station 31+50 are 9 to 14 feet below ground surface. East of Station 31+50, bedrock can be expected 2 to 3 feet beneath existing ground surface with large cobbles expected in the upper alluvial soils. We expect the bedrock surface to be steeply dipping underground. Depending on the width of the excavation, this bedrock may be encountered in the excavation. If bedrock is encountered in the excavation, we recommend that sufficient bedrock be removed and replaced with structural fill to provide a minimum 3-foot separation from the bottom of the retaining wall footing to i CITY OF FORT COLLINS 5 BOBCAT RIDGE AND CR 32C IMPROVEMENTS CTL I T PROJECT NO.

In addition, enough bedrock should be removed from alongside the proposed retaining wall structure to allow sufficient access for compaction equipment. In our opinion, the retaining wall can be founded with footing foundations bearing on the clayey to gravelly sands and sandy gravels. Footings should be designed for a maximum soil bearing pressure of 2,000 psf. A coefficient of friction of 0.5 between foundation concrete and the ground can be used to calculate resistance to sliding. A passive earth pressure calculated using an equivalent fluid density of 350 pcf can be added to calculate resistance to lateral loading provided the ground providing the passive resistance will not be removed. The ground under footings must be protected from freezing. Normally, 3 feet of ground cover is assumed in this area. The retaining wall will not be rigid, therefore; the sides should be designed for an "active" equivalent fluid density as provided in Figure 11 of this report. The equivalent fluid density values provided in Figure 11 do not include an allowance for hydrostatic pressure. The unbalanced hydrostatic pressure behind the wall caused by differential water levels across the wall can be relieved by providing a drain behind the wall or weep holes through the wall. Where soils are. loosened during excavation or in the forming process for footings, or if any loose soils are encountered at the footing level, the soils should be removed or re -compacted according to the following criteria priorto placing concrete. Footing subgrade should be moisture conditioned to between 2 percent below and 2 percent above optimum moisture content and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D 698). A representative from ourfirm should look at footing excavations prior to placing footing forms to confirm the subsurface conditions are as anticipated from our borings.

Backfill should be moisture conditioned to between 2 percent below and 2 percent above optimum moisture content, placed in thin, loose lifts and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D 698). A representative of our firm should observe placement and test the compaction of backfill while it is being placed. ROADWAY EMBANKMENT The alignment of the roadway is planned to be elevated from the existing grade in two areas of the project. Along the west end of the project, Station 6+00 to Station 16+00, the roadway is planned to be raised approximately 2 feet. The second area is at the eastern end of the project from Station 30+00 to Station 32+50, where the roadway is planned to be raised approximately 5 feet to allow the alignment to pass over a box culvert. Station 6+00 to Station 16+00 - The water feature along this portion of the roadway is primarily on the north side of the roadway. Raising the roadway along this portion will require extending the embankment slopes in.this area, possibly requiring relocation of the roadway to the south to avoid impacting the water channel. A near proximity rock outcrop was observed at Station 14+00 to Station 15+00 on the south side of the roadway. Moving the alignment south may require some removal of this outcrop. Station 30+00 to Station 32+50 - The water feature along this portion of the roadway is on the south side of the roadway from Station 30+00 to Station 31+50,where it crosses under the roadway and continues on the north side to the east. Due to the very limited width of the ravine and the proximity of the waterfeature, raising the roadway along this portion will require extending the embankment slopes in some areas and installing a retaining wall along the CITY OF FORT COLLINS - _ 7 BOBCAT RIDGE AND CR 32C IMPROVEMENTS CTL I T PROJECT NO.

It is understood that these rock outcrops are planned to be cut back to widen the ravine. Settlement of the proposed low embankment fills will primarily be related to compression of the natural soils beneath the fill. Stress increases in these materials will be related to the weight of the structural fill. We anticipate that minor settlement may occur and will likely be less than 1/2 inch. We expect these settlements to be elastic and should be predominately complete when the fill placement is complete. Due to the relatively low height of planned embankment fills, we do not anticipate slope stability to control the planned improvements. Performance of stability calculations to verify stable conditions was not a part of the project scope. ALTERNATE CONVEYANCE We have assumed that excavations for "alternate conveyance" to be less than 10 feet below the existing ground surface. Our borings indicate the excavation will be into the gravels and sands. Three of the four borings along the alternate conveyance encountered bedrock between 9 and 10 feet below existing ground surface. At boring location TH-12, bedrock was encountered at 6 feet and obtained practical refusal at 8_ feet below ground surface. This may affect the excavation methods selected if the, alternate conveyance is anticipated to extend to this depth. The soils in this area are generally sands and gravels with small amounts of silt and clay. These soils are prone to erosion by flowing water. Provision for surficial erosion control should be made that is appropriate for the anticipated velocity of the water passing through this structure. 9 CITY OF FORT COLLINS - $ BOBCAT RIDGE AND CR 32C IMPROVEMENTS CTL I T PROJECT NO. FC03705.125 S:IPROJECTS1FC03700 - FC03799\FC03705.000 - Bobcat Ridge CR 32C improvements\12512. Reports\Ri\FC03705-125 Bobcat Ridge S&F.doc EXCAVATIONS Based on the soils we encountered in the vicinity of the planned excavations for the culverts and alternate conveyance, we believe the excavations can be made with typical excavating machines. However, due to the proximity of the bedrock and rock outcrops and the vicinity of the planned excavations, the potential for encountering hard bedrock conditions exists. The hardness of the bedrock will require specialized excavation equipment, or, depending on the depth of the excavation into the bedrock, localized blasting may be. required. Excavations for the box culverts will likely need to be dewatered to construct the footings "in the dry". This will. involve a water -diverting plan to accommodate the flow volume of the water feature and limit the inflow of groundwater in the area. Based on the geology of the site, the groundwater in the area is likely attributed to the water feature. Once the flows of the water feature are diverted through the construction area, we believe that dewatering can be done by pumping from sumps within the excavation. The bottoms of the sumps should be 3 feet below the bottom of the excavation (or as deep as practical, considering the bedrock) so water pumped from the sumps will be drawn down through the soils. Groundwater movements up through the bearing soils should be avoided, as it is likely to destabilize the bearing capacity of the gravels and sands. Excavation sides will need to be sloped. We judge that the sands and gravels classify as Type C soils as defined by the OSHA rules and regulations. These regulations indicate a maximum allowable slope of 1.5:1 (horizontal:vertical) forType C soils. OSHA requires- the contractor employ a competent person "capable of identifying existing and predictable hazards in the surroundings, and who has authorization to take prompt corrective measures to eliminate them". This person should be sufficiently experienced to recognize the several soil types identified bythe CITY OF FORT COLLINS 9 BOBCAT RIDGE AND - CR 32C IMPROVEMENTS CTL I T PROJECT NO.

The contractor should be familiar with and follow all local, State and Federal safety regulations, particularly the current OSHA standards for excavations. Excavations deeper than 20 feet must be designed by a registered professional engineer experienced in slope stability analysis. SUBGRADE PREPARATION To prepare the subgrade for placement of embankment fill, subgrade soils should be scarified a minimum of 12 inches deep, moisture conditioned to between 2 percent below and 1 percent above optimum moisture content and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D 698). On -site soils substantially free of debris, organics or other deleterious materials are suitable for re -use as fill. Imported fill should consist of soils with properties similar or better than the on -site soils. A representative of ourfirm should observe placement and test compaction of fill. Proper grading and drainage, and maintaining moisture contents near optimum will be critical to avoid excessive deflections, rutting and pumping of the roadway during subgrade preparation. if moisture and density cannot be sufficiently controlled during subgrade preparation and stabilization is required, stabilization by removal and replacement or stabilization using geotextile fabrics and imported granular materials may be used. For isolated or small areas requiring stabilization, removal and replacement or "crowding" angular, coarse aggregate into the subgrade may be effective. CONCRETE Concrete that comes into contact with soils can be subject to sulfate attack. We measured water-soluble sulfate concentrations in one sample from this site. The concentration was measured at 0.036 in the alluvial soils. Sulfate concentrations less than 0.1 percent indicate Class 0 exposure to sulfate attack for concrete that comes into contact with the subsoils, according to the American Concrete Institute (ACI).

Surface Water Control: Surface water control generally falls in to the following -- categories: 1. Normal low flows along the channel; 2. Storm/flood flows along the channel; 3. Flows from existing storm drain pipelines; and, 4. Local surface inflows not conveyed by pipelines. The CONTRACTOR shall coordinate, evaluate, design, construct, and maintain temporary water conveyance systems. These systems shall not worsen flooding, alter major flow paths, or worsen flow characteristics during construction. The CONTRACTOR is responsible to ensure that any such worsening of flooding does not occur. The CONTRACTOR is solely responsible for determining the methods and adequacy of water control measures. At a minimum, the CONTRACTOR will be responsible for diverting the quantity of surface flow around the construction area so that the excavations will remain free of surface water for the time it takes to install these materials, and the time required for curing of any concrete or grout. The CONTRACTOR is cautioned that the minimum quantity of water to be diverted is for erosion control and construction purposes and not for general protection of the construction -site. It shall be the CONTRACTOR's responsibility to determine the quantity of water which shall be diverted to protect his work from damage caused by storm water. — The CONTRACTOR shall, at all times, maintain a flow path for all channels. Temporary structures such as berms, sandbags, pipeline diversions, etc., may be — permitted for the control of channel flow, as long as such measures are not a major obstruction to flood flows, do not worsen flooding, or alter historic flow routes. C. Groundwater Control: The CONTRACTOR shall install adequate measures to maintain the level of groundwater below the foundation subgrade elevation and maintain sufficient bearing capacity for all structures, pipelines, earthwork, and rock work. Such measures may include, but are not limited to, installation of perimeter subdrains, pumping from drilled holes or by pumping from sumps excavated below the subgrade elevation. The foundation bearing surfaces are to be kept dewatered and stable until the structures or other types of work are complete and backfilled. — Disturbance of foundation subgrade by CONTRACTOR operations shall not be considered as originally unsuitable foundation subgrade and shall be repaired at CONTRACTOR's expense.

If unsuitable materials are encountered, they shall be removed and replaced as Muck Excavation in accordance with Section 02315 of the Specifications. ^ Unsuitable materials shall be disposed of from the site by the CONTRACTOR at his expense. After an acceptable subgrade for granular bedding material is established, the bedding shall be immediately placed and leveled to the subgrade elevation. Immediately following this, the riprap shall be placed. If bedding material is disturbed for any reason, it shall be replaced and graded at the CONTRACTOR's expense. In -place bedding materials shall not be contaminated with soils, debris or vegetation before the riprap is placed. If contaminated, the bedding material shall be — removed and replaced at the CONTRACTOR's expense. 3.02 PLACEMENT A. Following acceptable placement of geotextile fabric, granular bedding, riprap placement shall commence as follows: Machine Placed Riprap: Riprap shall be placed on the prepared slope or channel bottom areas in a manner which will produce a reasonably well- _ graded mass of stone with the minimum practicable percentage of voids. Riprap shall be machine placed, unless otherwise stipulated in the Drawings or Specifications. — When riprap is placed on slopes, placement shall commence at the bottom of the slopes working up the slope. Place the riprap in a stepped fashion with the bottom of the uphill riprap below the top of the downhill riprap by half of the height of the riprap minimum. The entire mass of riprap shall be placed on either channel slopes or bottoms so as to be in conformance with the required gradation mixtures and to lines, grades, and thickness shown on the Drawings. Riprap shall be placed to its full course thickness at one operation and in such a manner as to avoid displacing the underlying bedding material. Placing of riprap in layers, or by dumping into chutes, or by similar methods shall not be permitted. All material going into riprap protection for channel slopes or bottoms shall be so placed and distributed that there will be no large accumulations of either the larger or smaller sizes of stone. Some hand placement may be — required to achieve this distribution. It is the intent of these Specifications to produce a fairly compact riprap protection in which all sizes of material are placed in their proper proportions. Unless otherwise authorized by the ENGINEER, the riprap protection shall be placed in conjunction with the construction of embankments or channel bottoms with only sufficient delay in construction _ of the riprap protection, as may be necessary, to allow for proper construction of the portion of the embankment and channel bottom which is to be protected. The CONTRACTOR shall maintain the riprap protection Bobcat Ridge Access Road 02375-4 Riprap Improvements June 2006 PAGE INTENTIONALLY LEFT BLANK, Bobcat Ridge Access Road 02710-6 Aggregate Base Course Improvements June 2006 C.

Drilling locations were generally limited by access conditions related to fences, trees, rock outcrops, utilities and slopes. Boring locations were chosen as near to proposed structures as possible. The roadway alignment and appropriate locations of our exploratory borings are shown on. Figure 1. Drilling was observed by our field representative who logged and sampled the soils and bedrock. Graphic logs of the borings, including results of field -penetration resistance tests, are presented on Figures 2 through 4. - Soil samples obtained during drilling were returned to our laboratory and visually examined by the geotechnical engineer for this project. Laboratory testing included moisture content and dry density, swell/consolidation, gradation analysis and water-soluble sulfate tests. Swelllconsolidation tests were wetted at a confining stress of 1,000 pounds per square foot (psf). Results of the laboratory tests are presented on Figure 5s through 10 and summarized in Table 1. SUBSURFACE CONDITIONS The roadway typically resides on mixed alluvial soils resulting from the historical erosion and deposition by the water feature previously described. The alluvial deposits were primarily sands and gravels with small amounts of silts and clays. Alluvial soils typically consist of three general groups, sandy gravels, sands and sandy clays. The sandy gravels are typically medium dense to very dense, moist to wet and brown. The sands contain minor amounts of silt, clay and gravels, and are loose to dense, slightly dry to moist and brown, dark brown and reddish brown in color. Our laboratorytesting indicated natural densities of 98 to 117 pounds per cubic foot and exhibited typically non -expansive characteristics. The clays are sandy, stiff to very stiff, very moist to wet and brown to dark brown. Our laboratory testing indicated a natural density of approximately 97 pounds per cubic foot and exhibited slight consolidation when wetted.

ENGINEER will, within ten days after receipt of each Application for Payment, either indicate in writing a EJCDC GENERAL CONDITIONS 1910-8 (1990 Edtim) w/ CITY OF FORT COLLINS MODIFICATIONS (REV 4/2000) recommendation of payment and present the Application to OWNER, or return the Application to CONTRACTOR indicating in writing ENGINEER's reasons for refusing to recommend payment. In the latter case, CONTRACTOR may make the necessary corrections and resubmit the Application. Ten days after presentation of the Application for Payment to OWNER with ENGINEER's recommendation, the amount recommended will (subject to the provisions of the last sentence of paragraph 14.7) become due and when due will be paid by OWNER to CONTRACTOR. 14.5, ENGINEER's recommendation of any payment requested in an Application for Payment will constitute a representation by ENGINEER to OWNER, based on ENGINEER's on -site observations of the executed Work as an experienced and qualified design professional and on ENGINEER's review of the Application for Payment and the accompanying data and schedules, that to the best of ENGINEER's knowledge, information and belief., 14.5.1. the Work has progressed to the point indicated, 14.5.2. the quality of the Work is generally in accordance with the Contract Documents (subject to an evaluation of the Work as a functioning whole prior to or upon Substantial Completion, to the results of any subsequent tests called for in the Contract Documents, to a final determination of quantities and classifications for Unit Price Work under paragraph 9.10, and to any other qualifRxtiois stated in the recommendation), and 14.5.3. the conditions precedent to CONTRACTOR's being entitled to such payment appear to have been fulfilled insofar as it is ENGINEER's responsibility to observe the Work. However, by recommending any such payment ENGINEER will not thereby be deemed to have represented that (i) exhaustive or continuous on -site inspections Have been made to check the quality or the quantity of the Work beyond the responsibilities specifically assigned to ENGINEER in the Contract Documents or (ii) that there may not be other matters or issues between the parties that might entitle CONTRACTOR to be paid additionally by OWNER or entitle OWNER to withhold payinent to CONTRACTOR 14.6. ENGINEER'S recommendation of any payment, including final payment, shall not mean that ENGINEER is responsible for CONTRACTORS means, methods, techniques, sequences or procedures of construction, or the safety precautions and programs incident thereto, or for any failure of CONTRACTOR to comply with Laws and Regulations applicable to the furnishing or performance of Work, or for any failure of CONTRACTOR to perform or furnish Work in accordance with the Contract Documents. 14.7. ENGINEER may refuse to recommend the whole or any part of any payment if, in ENGINEER's opinion, it. would be incorrect to make the representations to 29 OWNER referred to in paragraph 14.5. ENGINEER may also refuse to recommend any such payment, or, because of subsequently discovered evidence or the results of subsequent inspections or tests, nullify any such payment previously recommended to such extent as may be necessary in ENGINEER'S opinion to protect OWNER from loss because: 14.7.1. the Work is defective, or completed Work has been damaged requiring correction or replacement, 14.7.2. the Contract Price has been reduced by Written Amendment or Change Order, 14.7.3. OWNER has been required to correct defective Work or complete Work in accordance with paragraph 13.14, or 14.7.4. ENGINEER has actual knowledge of the occurrence of any of the events enumerated in paragraphs 15.2.1 through 15.2.4 inclusive. OWNER may refuse to make payment of the full amount recommended by ENGINEER because: 14.7.5. claims have been made against OWNER on account of CONTRACTOR's performance or fam shing of the Work, 14.7.6. Liens have been filed in connection with the Work, except where CONTRACTOR has delivered a specific Bond satisfactory to OWNER to secure the satisfaction and discharge of such Liens, 14.7.7. there are other items entitling OWNER to a set- off against the amount recommended, or 14.7.8. OWNER has actual knowledge of the occurrence of any of the events enumerated in paragraphs 14.7.1 through 14.7.3 or paragraphs 15.2.1 through 15.2.4 inclusive; but OWNER must give CONTRACTOR immediate written notice (with a copy to ENGINEER) stating the reasons for such action and promptly pay CONTRACTOR the amount so withheld, or any adjustment thereto agreed to by OWNER and CONTRACTOR, when CONTRACTOR corrects to OWNER'S satisfaction the reasons for such action Substantial Completion: 14.8. When CONTRACTOR considers the entire Work ready for its intended use CONTRACTOR shall notify OWNER and ENGINEER in writing that the entire Work is substantially complete (except for items specifically listed by CONTRACTOR as incomplete) and request that ENGINEER issue a certificate of Substantial Completion. Within a reasonable time thereafter, OWNER, CONTRACTOR and ENGINEER shall make an inspection of the Work to determine the status of completion. If ENGINEER does not consider the Work substantially complete, ENGINEER will notify CONTRACTOR in writing giving the reasons therefor. If ENGINEER EICDC GENERAL CONDITIONS 1910-8 (1990 Ediniar) 30 w/CITY OF FORT COLLINS MODIFICATIONS(REV4/2000) considers the Work substantially complete, ENGINEER will prepare and deliver to OWNER a tentative certificate of Substantial Completion which shall fix the date of Substantial Completion. There shall be attached to the certificate a tentative list of items to be completed or corrected before final payment. OWNER shall have seven days after receipt of the tentative certificate during which to make written objection to ENGINEER as to any provisions of the certificate or attached list. If, after considering such objections, ENGINEER concludes that the Work is not substantially complete, ENGINEER will within fourteen days after submission of the tentative certificate to OWNER notify CONTRACTOR in writing, stating the reasons therefor. If, after consideration of OWNER's objections, ENGINEER considers the Work substantially complete, ENGINEER will within said fourteen days execute and deliver to OWNER and CONTRACTOR a definitive certificate of Substantial Completion (with a revised tentative list of items to be completed or corrected) reflecting such changes from the tentative certificate as ENGINEER believes justified after consideration of any objections from OWNER. At the time of delivery of the tentative certificate of Substantial Completion ENGINEER will deliver to OWNER and CONTRACTOR a written recommendation as to division of responsibilities pending final payment between OWNER and CONTRACTOR with respect to security, operation, safety, maintenance, heat, utilities, insurance and warranties and guarantees. Unless OWNER and CONTRACTOR agree otherwise in writing and so inform ENGINEER in writing prior to ENGINEER's issuing the definitive certificate of Substantial Completion, ENGINEER'S aforesaid recommendatim will be binding on OWNER and CONTRACTOR until final payment. 14.9. OWNER shall have the right to exclude CONTRACTOR from the Work after the date of Substantial Completion; but OWNER shall allow CONTRACTOR reasonable access to complete or correct items on the tentative list. Partial Utilization: 14.10. Use by.
