(Our Clock) October 21, 2008 To all prospective bidders under the specifications and contract documents described above, the following changes are hereby made. CHANGE: The Opening Date has been changed to 3:00 P.M. (Our Clock) October 21, 2008 No further questions will be accepted. CLARIFICATIONS AND ADDENDA ITEMS O. Is there a spec section for the passive anode? Is this a prepackaged weight, or the weight of the anode itself? Is this zinc? Magnesium? A. There is not a specification section for the anodes. Contractors shall provide a magnesium anode. The weight listed in the plans is the anode weight — not prepackaged. O. Can you help me understand the steel pipe? I can't figure out if you want coal tar coated, tape coated, or some other coating. A. Specification Section 02615 allows for either coating. AWWA C203 outlines the coating requirements for Coal -Tart applied coatings. AWWA C209 addresses tape wrap. The Contractor shall maintain a consistent coating system for the entire principal outlet installation. It is recommended that the Contractor use the AWWA C209 specification as it is easier to apply in cold weather applications. This specification calls for spirally wrapped tape, 55 percent overlap, 50 mils minimum thickness. O. What type of joints are to be provided - butt welds, welded bells, 0-rings, flanges? A. This question was addressed in Addendum Number 1. The Contractor is advised that considering a hydrostatic test is required, flanged end sections will likely be needed. The test parameters shown above apply to both the 24-inch principal outlet and the 10- inch irrigation outlet. The 6-inch toe drain will be visually inspected as installation occurs. The 1-1/2" stainless steel/DR 11 flushing pipe will be visually inspected during installation. Q. What are the extents of installation of the 1-1/2" flushing line included as part of the 12-inch irrigation line installation? A. It is expected that this flushing line will daylight into the irrigation wet well at STA 0+00 (Sheet C10) with a solid, galvanized vertical riser pipe connected to the inside of the manhole ending with a brass 1-1/2" threaded fitting, capped. The penetration of this line through the manhole shall be sealed with link -seal similar to that of the 12-inch irrigation line shown on sheet IRR1. Q. Please clarify the hydraulic operation of the irrigation line leading to the wet well. A. The 12-inch irrigation line is intended to hydraulically connect the reservoir to the irrigation wet well. This will be accomplished through the installation of the intake screen, 12-inch irrigation pipeline, intermediate manhole and wet well manhole. The manhole shown at STA 1+65 (Sheet C10) shall include a bolt down lid as noted on detail 8/13, Sheet C12. The plans shall be modified to include construction of the 10-inch 0900 PVC irrigation line continuous through this manhole providing a 10-inch MJ by 10" flanged DI tee with blind flange for future access and testing. The gate valve shown at STA 1+49 shall be moved to STA 1+75 to isolate the intermediate manhole. Q. Is the project tax exempt? A. Yes. The project is tax exempt extending to permanent materials incorporated into the project. The city has supplied a tax exempt certificate inside the contract documents and will provide their tax exempt number to the successful bidder. Q. The specifications call for the rip rap color to be blue -gray. Historically this supplier has been the Andesite mine near Lyons. They are no longer in business. Will the city consider a change to this specification? A. Yes. Section 02375, Part 2 — Products; Subsection 2.01 A, Item 5 is hereby revised to read as follows. The color of the riprap shall be as approved by the Owner prior to delivery to the project site. Riprap color shall be consistent on the entire project. A specific color is not required for this work as the riprap is buried. The Contractor shall mix the Class 12 (Type M) riprap with onsite topsoil material prior to placement and finish the work with 6-inches of topsoil covering as shown on Sheet C12. Q. Is there geotextile fabric required around the toe drain bedding/fliter material? A. No. Detail 3/12 on sheet C11 outlines the toe drain bedding requirement. CDOT Class A (3/4" minus) filter material is required as bedding/filter material. The slotted PVC SCH 40 toe drain line should include slots 1 /8" (max) in width spaced evenly along each pipe segment spaced approximately every 6-inches. Q. When will be the last day for questions on this project? A. The city will accept questions from contractors on this project until end of business (5 pm MST), October 9, 2008. for Payment or otherwise).

The Work Sequence is to be submitted as part of the construction schedule required in Section 01320. Construction of the project shall begin within seven (7) calendar days of the date of Notice to Proceed. 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. Every effort shall be made by the Contractor to complete the project within the "Contract Time" shown in the proposal. The "Contract Tune" 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) Robert Benson Dam 01010-1 Summary of Work 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 excepted) 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, 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 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. To any preference, priority, or allocation order duly issued by the Owner. Robert Benson Dam 01010-2 Summary of Work 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. Other than the conditions above, Contractor is permitted to start the work at any location within the project site. The Contractor shall adhere to the construction traffic control requirements delineated in Section 01555 and on the Drawings. 1.03 UNDERGROUND UTILITIES A. It shall be the responsibility of the CONTRACTOR to verify the existence and location of all underground utilities along the route of the work and to coordinate the construction schedules with these utility owners. B. 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 from field 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. The CONTRACTOR shall field verify all utilities and coordinate construction with utility owners prior to starting construction.

END OF SECTION Robert Benson Dam 02235-2 Native Soil SECTION 02240 WATER CONTROL AND DEWATERING PARTS GENERAL 1.01 SECTION INCLUDES A. The work of this section consists of controlling groundwater, site drainage, and storm flows during construction. The CONTRACTOR is cautioned that the work involves construction in and around drainage channels, local streams or rivers, and areas of local drainage. These areas are subject to frequent periodic inundation. 1.02 RELATED SECTIONS A. Section 02315 — Excavation and Embankments PART2 PRODUCTS 2.01 MATERIALS A. On -site materials may be used within the limits of construction to construct temporary dams and berms. The materials such as plastic sheeting, sand bags, and storm sewer pipe may also be used if desired by the CONTRACTOR. PART EXECUTION 3.01 CONSTRUCTION REQUIREMENTS A. General: For all excavation, the CONTRACTOR shall provide suitable equipment and labor to remove water, and he shall keep the excavation dewatered so that construction can be carried on under dewatered conditions where required by the Drawings and Specifications. Water control shall be accomplished such that no damage is done to adjacent channel banks or structures. The CONTRACTOR is responsible for investigating and familiarizing himself with all site conditions that may affect the work including surface water, level of groundwater and the time of year the work is to be done. All excavations made as part of dewatering operations shall be backfilled with the same type material as was removed and compacted to 95% of Maximum Standard Proctor Density (ASTM D698) except where replacement by other materials and/or methods are required. The cost for this excavation and backfdling shall be included in the Construction Dewatering bid item. The CONTRACTOR shall conduct his operation in such a manner that storm or other waters may proceed uninterrupted along their existing drainage courses. By submitting a bid, the CONTRACTOR acknowledges that he has investigated the risk arising from such waters and has prepared his bid accordingly, and assumes all of said risk. At no time during construction shall the CONTRACTOR affect existing surface or subsurface drainage patterns of adjacent property. Any damage to adjacent property resulting from the CONTRACTOR's alteration of surface or subsurface drainage patterns shall be repaired by the CONTRACTOR at no additional cost to the OWNER. CONTRACTOR shall remove all temporary water control facilities when they are no longer needed or at the completion of the project. Robert Benson Dam 02240-1 Water Control and Dewatering Pumps and generators used for dewatering and water control shall be quiet equipment enclosed in sound deadening devices. B. 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. Any temporary dewatering ,trenches or well points shall be restored following dewatering operations to reduce permeability in those areas as approved by the ENGINEER. CONTRACTOR is to restore any areas disturbed by the dewatering operations to their original condition. Robert Benson Dam 02240-2 Water Control and Dewatering D. Contaminated Groundwater Control: CONTRACTOR shall not discharge contaminated water exceeding local, State and/or Federal limits to above ground channels or watercourses. END OF SECTION Robert Benson Dam 02240-3 Water Control and Dewatering THIS PAGE INTENTIONALLY LEFT BLANK. Robert Benson Dam 02240-4 Water Control and Dewatering Q. What is the interior lining, cement? A. Specification Section 02615, Part C shall include the following: 8. The interior pipe coating (lining) shall be cement mortar per AW WA C205. Interior pipe joints shall not have mortar lining unless excessively damaged during installation and welding as determined by the Engineer. Q. Is there a detail for the concrete encasement of the pipes through the dam breach? Reber? Size and shape of encasement? Will a concrete protective layer or mud mat be required on lop of the excavated subgrade through the dam breach to protect the subgrade during pipe installation and concrete encasement? A. The concrete encasement detail is outlined on sheets C9, C10 and C12 of the plans. The Contractor is to encase each pipe (principal outlet and irrigation line) in unreinforced concrete 1-foot minimum all sides. The Contractor shall take measures he/she deems necessary to protect the subgrade during pipe installation. The plans do not call for any subgrade protection. Q. How will we determine whether we are excavating muck or not. Since the muck excavation does not include under structures will muck excavation require replacement of the excavated material? Who is going to quantify where the "muck" starts and excavation stops? A. This question is largely addressed in Addendum No. 1. Muck excavation will only be paid to the lines and grades shown on the drawing. This amount is estimated to be the area upstream of the outlet works. Further muck excavation to install various project components (e.g. pipe, outlet structure, etc.) will not be measured and paid for separately. It is the Contractor's responsibility to estimate these quantities and include them in the various work items. Muck excavation that is paid for as part of Item 12 will be measured in the field by the Resident Engineer and agreed to with the Contractor. Q. On the embankment specifications requirements on moisture and density I do not see a performance spec, is this correct or are you going to specify the exact pieces of equipment we are to use to perform the embankments? A. The specifications do not dictate Contractor means and methods. The Contractor shall use the appropriate equipment to meet the embankment specification as written. Q. In regards the fills on the front and back of the dam, will this require benching to achieve a minimum of 8 ft wide work area per the specs? If so will we be allowed to bench Into the existing dam or will we have to over fill the face and then trim out the excess material? A. This question was addressed in Addendum No. 1. The Contractor will be able to bench the fills into the existing dam. Q. If Muck excavation is required for the dam breach I assume that the spec for 1.1/2" stabilization rock is not correct and we are to use previously excavated material to replace the muck, is that correct? A. Yes. The stabilization of the pipe trench will need to occur with previously excavated material. The Contractor will not be paid for Muck Excavation as part of this work but should include this cost in Item No. 18 Principal Outlet —24 inch Steel Pipe or Item No. 26 Irrigation — 10-inch C900 PVC Irrigation Pipe.

Embankment material may consist of approved material acquired from excavations or material hauled from outside the project limits, Suitable material identified on -site shall be used first for embankments and backfill. ,access excavated native soils which are not used as embankment or backfill shall become the property of the CONTRACTOR and shall be disposed of off -site by the CONTRACTOR, in a location acceptable to the ENGINEER. B. Muck excavation encountered in all areas shall also include the replacement of excavated muck with uniformly graded rock, riprap, on -site or imported soils, or other material whichever is most suitable for the specific situation encountered. The ENGINEER will determine which type of aggregate or other material which shall be used after observing the specific site conditions. PART EXECUTION 3.01 GENERAL EXCAVATION/EMBANKMENT A. 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: 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 Robert Benson Dam 02315-2 Excavation and Embankment 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". 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 out face. 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 the placing and compacting of embankment material in holes, pits and other depressions within the project area. Only approved materials shall be used in the construction of embankments and backfills. Approved materials shall consist of clean on -site cohesive soils or approved imported soils. On -site cohesive soils are suitable for use as compacted fill provided the following recommendations are met: Percent Finer by Weight Gradation (ASTM 6136) %:-Inch 100 3/8-Inch 70 —100 No. 4 Sieve 50 —100 No. 200 Sieve 60 (min) Liquid Limit 35 (max) Plasticity Index 20 (max) In -Situ Coefficient of Permeability 1x10.6 cm/sec Excavation and Embankment will only be paid when a significant change in grade is required, as determined by the ENGINEER. Minor cuts and fills will be considered incidental to the work, and will not be paid for separately under this section. Robert Benson Dam 02315-3 Excavation and Embankment Ou-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 embanlanent 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 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 Robert Benson Dam 02315-4 Excavation and Embankment ENGINEER and in accordance with the Drawings and Specifications at the CONTRACTOR's sole expense. Removed unsuitable materials shall be hauled away and disposed of at the CONTRACTOR's expense. Placing of replacement materials for removed unsuitable materials shall be purchased, placed and compacted at the CONTRACTOR' expense. D. Proof rolling with a heavy rubber tired roller will be required, if designated on the Drawings or when ordered by the ENGINEER. Proof rolling shall be done after specified compaction has been obtained. Areas found to be weak and those areas which failed shall be ripped, scarified, wetted if necessary, and recompacted to the requirements for density and moisture at the CONTRACTOR's expense. Proof rolling shall be done with equipment and in a manner acceptable to the ENGINEER. Proof rolling as shown on the Drawings or as ordered by the ENGINEER shall not be measured and paid for separately, but shall be included in the unit prices bid for the work. 3.02 EXCAVATION AND BACKFILL FOR STRUCTURES A. Poor foundation material for any of the work shall be removed, by the CONTRACTOR, as directed by the ENGINEER. The CONTRACTOR will be compensated for removal and replacement of such materials in accordance with Muck Excavation. The CONTRACTOR is cautioned that construction equipment may cause the natural soils to pump or deform while performing excavation work inside and on footings, structural floor slabs, or other structure foundation areas. Foundation materials which are: a) saturated by either surface or subsurface flows due to the lack of adequate water control or dewatering work by the CONTRACTOR; b) frozen for any reason; or, c) that are disturbed by the CONTRACTOR's work or caused to become unacceptable for foundation material purposes by means of the CONTRACTOR's equipment, manpower, or methods of work shall be removed and replaced by the CONTRACTOR at his expense. Dewatering should not be conducted by pumping from inside footing, structural floor slab, or other structure foundation limits. This may decrease the supporting capacity of the soils. Care should be taken when excavating the foundations to avoid disturbing the supporting materials. Excavation by either hand or careful backhoe soil removal, may be required in excavating the last few inches of material to obtain the subgrade of any item of the concrete work. Any over -excavated subgrades that are due to the CONTRACTOR's actions, shall be brought back to subgrade elevations by the CONTRACTOR and at his expense in the following manner. Robert Benson Dam 02315-5 Excavation and Embankment For over -excavations of 2 inches or less, either: Backfill and compact with an approved granular materials; backfill with 1/2 inch crushed rock; or fill within concrete at the time of the appurtenant structure concrete pour. 2. For over -excavations greater than 2 inches, backfill and compact with an approved granular material. All granular footings, structural floor slabs, or other structure areas shall be compacted with a vibratory plate compactor prior to placement of concrete, reinforcing, or bedding materials. B. Backfill, and fill within 2 feet of and adjacent to all structures and for full height of the walls, shall be selected non -swelling material. It shall be granular, well graded, and free from stones larger than 3 inches. Material may be job excavated, but selectivity will be required as determined by the ENGINEER. Refer to the Drawings for job specific requirements. Stockpiled material, other than topsoil from the excavation shall be used for backfrlling unless an impervious structural backfill is specified. The backfill material shall consist of either clean on -site granular materials free of stones larger than 3 inches in diameter with no more than 20% passing the No. 200 sieve, or equivalent imported materials. All backfill around the structures shall be consolidated by mechanical tamping. The material shall be placed in 8-inch loose lifts within a range of 2% above to 2% below the optimum moisture content and compacted to 95% of Maximum Standard Proctor Density (ASTM D698) for cohesive soils, or to 70% relative density for pervious material as determined by the relative density of cohesionless soils test, ASTM D4253. When specified on the Drawings or as required by the ENGINEER, Class I structural backfill shall meet the following gradation requirements: % by Weight Passing Sieve Size Square Mesh Sieves 2-Inch 100 No. 4 30 - 100 No. 50 10 — 60 No. 200 5 — 20 In addition, this material shall have a liquid limit not exceeding 35 and a plasticity index of not over 6.

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 Robert Benson Dam 02375-4 Riprap until accepted. Any material displaced for any reason shall be replaced to the lines and grades shown on the Drawings at no additional cost to the OWNER. If the bedding materials are removed or disturbed, such material shall be replaced prior to replacing the displaced riprap. 2. Hand Placed Riprap: Hand placed riprap shall be performed during machine placement of riprap and shall conform to all the requirements of Section 02375 PART 1 above. Hand placed riprap shall also be required when the depth of riprap is less than 2 times the nominal stone size, or when required by the Drawings or Specifications. After the riprap has been placed, hand placing or rearranging of individual stones by mechanical equipment shall be required to the extent necessary to secure a flat uniform surface and the specified depth of riprap, to the lines and grades as shown on the Drawings. 3. Soil Replacement In and Over Riprap: Where riprap is designated to be buried, place onsite excavated material that is free from trash and organic matter in riprap voids by washing and rodding. Prevent excessive washing of material into stream. When voids are filled and the surface accepted by the ENGINEER, place a nominal 6 inches of soil over the area, or as designated on the Drawings. Fine grade, seed, and mulch per the Specifications. 4. Rejection of Work and Materials: The ENGINEER shall reject placed riprap which does not conform to this Section and the CONTRACTOR shall immediately remove and relay the riprap to conform with said sections. Riprap shall be rejected, which is either delivered to the job site or placed, that does not conform to this Section. Rejected riprap shall be removed from the project site by the CONTRACTOR and at his expense. 5. Geotextile fabric shall be installed according to the manufacturer's specifications. Material proposed for use shall be submitted and approved by the ENGINEER prior to installation. END OF SECTION Robert Benson Dam 02375-5 Riprap THIS PAGE INTENTIONALLY BLANK.

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 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 Robert Benson 02710-2 Aggregate Base Course 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 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 % 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 backftll 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. Robert Benson 02710-3 Aggregate Base Course 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. 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 minimisegregation 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 will cause segregation between the coarse and fine materials is prohibited. 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. Robert Benson 02710-4 Aggregate Base Course 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 MDOING A. General: Unless otherwise specified, the CONTRACTOR shall mix the aggregate by any one of the three following methods. 1. Stationary Plant Method: Aggregate base course and water shall be mixed in an approved mixer. After mixing the aggregate shall be transported to the project site while it contains the proper moisture content and shall be placed on the roadbed by means of an approved spreader. 2. Travel Plant Method After the material for each layer has been placed through an aggregate spreader or windrow sizing device, it shall be uniformly mixed by a traveling mixing plant. 3. Road Mix Method After material for each layer has been placed, the materials shall be mixed while at an optimum moisture content by motor graders or other approved equipment until the mixture is uniform throughout. 3.06 SHOULDER CONSTRUCTION A. Shoulders shall be constructed with base course material to conform to the elevation and section shown in the Drawings. No equipment shall be used which by its design or through its manner of operation that will damage the pavement or curbs. Insofar as practicable, the base course material shall be placed directly on the shoulder area. Materials that are deposited outside the shoulder area, if not contaminated, shall be recovered and placed within the required limits. The CONTRACTOR will not be compensated for materials not recovered as determined by the ENGINEER. Materials shall not be deposited on the pavement or surfacing during placing unless specifically permitted by the ENGINEER. Robert Benson 02710-5 Aggregate Base Course The base course material as placed shall be spread and compacted to the required density in layers not exceeding six inches in compacted thickness. Any material inadvertently placed on the pavement shall be broomed from the pavement. The result shall not effect a change in the gradation of the shoulder material.

Concrete transported in truck mixers or truck agitators shall be delivered to the site of the work and completely discharged within a period of ninety (90) minutes after the cement comes in contact with the mixing water or with the combined aggregates containing free moisture in excess of 2% by weight. The concrete shall be placed either by an approved slip form/extrusion machine, by the formed method, or by a combination of these methods. The subgrade shall be conditioned to provide a uniformly moist surface when concrete is placed. u 4515 r A. The slip form/extrusion machine shall be so designed to place, spread, consolidate, screed, and finish the concrete in one complete pass in such a manner that a minimum of hand finishing will be necessary to provide a dense and homogenous concrete section. The machine shall shape, vibrate, and/or extrude the concrete for the full width and depth of the concrete section being placed. It shall be operated with as nearly a continuous forward movement as possible. All operations of mixing, delivery, and spreading concrete shall be so coordinated as to provide uniform progress, with stopping and starting of the machine held to a minimum. ct3 • ela I41.6R A. The vertical face of previously sawed and adjacent asphalt pavement may NOT be used.as a funning surface. The CONTRACTOR shall use forms on front and back of all curb and gutter, sidewalks and crosspans. The forms shall be of metal or other suitable material that is straight and free from warp, having sufficient strength to resist the pressure of the concrete without displacement and sufficient tightness to prevent the leakage of mortar. Flexible or Robert Benson 02770-4 Miscellaneous Concrete rigid forms of proper curvature may be used for curves having a radius of 100 feet or less. Division plates shall be metal. Where directed by the ENGINEER the CONTRACTOR shall use a thin metal back form to preserve landscaping, sprinklers, etc. Form must be straight and rigid and must be approved by the ENGINEER prior to use on project. The front and back forms shall extend for the full depth of the concrete. All of the forms shall be braced and staked so that they remain in both horizontal and vertical alignment until their removal. No wooden stakes will be allowed. They shall be cleaned and coated with an approved form -release agent before concrete is placed against them. The concrete shall be deposited into the forms without segregation and then it shall be tamped and spaded or mechanically vibrated for thorough consolidation. Low roll or mountable curbs may be formed without the use of a face form by using a straight edge and template to form the curb face. When used, face forms shall be removed as soon as possible to permit finishing. Front and back forms shall be removed without damage to the concrete after it has set. i - Should the removal of adjacent asphalt pavement be required beyond that shown in the asphalt patch detail to properly correct failed concrete . sections, the CONTRACTOR shall remove and replace said asphalt pavement to such an extent as to provide a smooth repair.

Joint depth shall average at least one-fourth of the cross-section of the concrete. b. Contraction joints may be sawed, hand -formed, or made by one eighth -inch (1/8") thick division plates in the formwork. Sawing shall be done early after the concrete has set to prevent the formation of uncontrolled cracking. The joints may be hand -formed either by (1) using a narrow or triangular jointing tool or a thin metal blade to impress a plane of weakness into the plastic concrete, or (2) inserting one eighth -inch (1/8') thick steel strips into the plastic concrete temporarily. Steel strips shall be withdrawn before final finishing of the concrete. Where division plates are used to make contraction joints, the plates shall be removed after the concrete has set and while the forms are still in place. Robert Benson 02770-5 Miscellaneous Concrete B. Expansion Joints: Expansion joints shall be constructed at right angles to the curb line or as shown on the Drawings at immovable structures and at points of curvature for short radius curves. Filler material for expansion joints shall be silicon or asphalt based and shall be submitted for approval according to Section 1.03 and shall be furnished in a single one half -inch (1/2") thick piece for the full depth and width of the joint. Expansion joints in a slip formed curb or curb -and -gutter shall be constructed with an appropriate band tool by raking or sawing through partially set concrete for the full depth and width of the section. The cut shall be only wide enough to permit a snug fit for the joint filler. After the filler is placed, open areas adjacent to the filler shall be filled with concrete and then troweled and edged. The CONTRACTOR may choose to place the filler and pour the concrete around it. Alternately, an expansion joint may be installed by removing a short section of freshly extruded curb -and -gutter immediately, installing temporary holding forms, placing the expansion joint filler, and replacing and reconsolidating the concrete that was removed. Contaminated concrete shall be discarded. Constriction joints, may be either butt or expansion -type joints. Curbs or combined curbs and gutters constructed adjacent to existing concrete shall have the same type of joints as in the existing concrete, with similar spacing; however, contraction joint spacing shall not exceed ten feet (10'). 3.07 PROTECTION A. The CONTRACTOR shall always have materials available to protect the surface of the plastic concrete against rain. These materials shall consist of waterproof paper or plastic sheeting. For slip form construction, materials such as wood planks or forms to protect the edges shall also be required. Concrete damaged by rain shall be required to be removed and replaced at the CONTRACTOR's expense. Concrete being placed in cold weather during which the temperature may be expected to drop below 350F., shall be suitably protected to keep the concrete from freezing until it is at least ten (10) days old or as directed by the ENGINEER. Concrete injured by frost action shall be required to be removed and replaced at the CONTRACTOR's expense. The CONTRACTOR will be responsible for correcting any vandalism or defacement (graffiti) that occurs on the concrete prior to final acceptance. 3.08 CURING A. Concrete shall be cured for at least seven (7) days after placement to protect against loss of moisture, rapid temperature change, and mechanical injury prior to any overlay or reconstruction work. Moist burlap, waterproof paper, white polyethylene sheeting, white liquid membrane compound, or a combination thereof may be used as the curing material. Membrane curing shall not be permitted infrost-affected areas when the concrete will be exposed to deicing chemicals within thirty (30) days after completion of the curing period. 3.09 BACKFIL LING Robert. Benson 02770-6 Miscellaneous Concrete A.

"Truck mixed" concrete as defined in ASTM C 94 shall not be permitted. Mixing time shall be measured from the time water is added to the mix, or cement contracts the aggregate. All concrete shall be homogeneous and thoroughly mixed, and there shall be no lumps or evidence of undispersed cement. Mixers and agitators, which have an accumulation .of hard concrete or mortar, shall not be used. Ready -mixed concrete shall be mixed and transported in accordance with ASTM C 94. The temperature of mixed concrete, immediately before placing shall not be less than 50°F or more than 80°F for slabs larger than 10,000 square feet and not be less than 50°F or more than 850F for walls. Aggregates and water shall be heated or cooled as necessary to produce concrete within these temperature limits. Neither aggregates nor mixing water shall be heated to exceed 150°F. The time elapsing from the time water is added to the mix (or the cement comes in contact with aggregate) until the concrete is deposited in place at the site of the work shall not exceed 45 minutes when the concrete is hauled in non -agitating trucks, nor more than 90 minutes when hauled in truck mixers or truck agitators. The batch shall be so charged into the drum that a portion of the mixing water shall enter in advance of the cement and aggregates. The flow of water shall be uniform and all water shall be in the drum by the end of the first 1/4 of the specified mixing time. Cement shall be charged into the mixer by meaps that will not result in loss of cement due to the effect of wind, or in accumulation of cement on surfaces of hoppers or in other conditions which reduce or vary the required quantity of cement in the concrete mixture. 2.07 TRANSPORTING MIXED CONCRETE - MDiED CONCRETE OR TRUCK MDMRS Transporting of mixed concrete shall conform to ASTM C 94. Truck agitators shall be loaded not to exceed the manufacturer's guaranteed capacity. They shall maintain the mixed concrete in a thoroughly mixed and uniform mass during hauling. No additional mixing water shall be incorporated into the concrete during hauling or after arrival at the delivery point, unless approved. If additional water is to be incorporated into the concrete at the site, the drum shall be revolved not less than 30 revolutions at mixing speed after the water is added and before discharge is commenced. One addition of water at the site to adjust mix workability is permitted but the maximum water cement ratio shall not be exceeded. Robert Benson Dam 03310-6 Structural Concrete The CONTRACTOR shall furnish a water -measuring device in good working condition, mounted on each transit mix truck, for measuring the water added to the mix on the site. All water tanks on transit mix trucks shall be filled prior to being batched and arrive at the construction site 100% full. Each load of ready mixed concrete delivered at the job shall be accompanied by the ticket referencing design mix and showing volume of concrete, the weight of cement in pounds, percent of free water in coarse and dry aggregates, and the total weight of all ingredients in pounds. The ticket shall also show the time of day at which the materials were batched and the reading of the revolution counter at the time the truck mixer is charged. See Paragraph 1.08. 2.08 COMPRESSIVE STRENGTH Concrete compressive strength requirements consist of a minimum strength that must be obtained before various loads of stresses are applied to the concrete and, for concrete designated by strength, a minimum strength at the age of 28 days. Unless otherwise shown on the Drawings the 28-day compressive strength of structural concrete shall be a minimum of 4,000 psi. The mix shall be designed for required strengths in accordance with ACI 301. The ratio of water to the sum of concrete + pozzolan shall not exceed 0.41 by weight for durable, watertight, concrete. The amount of fly ash in the mix shall be between 15 and 20,percent by weight of the total cementitious materials. 2.09 CONCRETE VIBRATORS Concrete vibrators for consolidating concrete shall be 2 1/2 inch diameter "high cycle" vibrators with a frequency under load of 8,000 - 10,400 vibrations per minute (vpm). Concrete vibrators of lesser capacity are unacceptable for use in any part of the construction. The CONTRACTOR shall have at least one standby concrete vibrator ready for use for every two concrete vibrators in use during a concrete placement. PART EXECUTION 3.01 PRIOR TO PLACEMENT Prior to placing concrete the CONTRACTOR shall remove all debris and thoroughly dampen the surfaces that will be in contact with the concrete to be placed. The CONTRACTOR shall use compressed air from an air -compressor to blow-out construction debris and dirt at the bottom of members to be placed such as walls, beams and columns, prior to final placement of forms that will obscure any joint. The CONTRACTOR shall demonstrate to the ENGINEER that all debris, such as concrete particles, saw dust, loose tie wire, bar tags, tape, trash and dirt, have been thoroughly removed. No concrete shall be placed when form surfaces that will be in contact with the concrete, Robert Benson Dam 03310-7 Structural Concrete reinforcement, embedded items or sub -base is less than 32°F. When the mean daily outdoor temperature is less than 40°F, the temperature of the concrete shall be maintained between 50°F and 70°F for the required curing period. When necessary, arrangements for heating, covering, insulating, or housing the concrete work shall be made in advance of placement and shall be adequate to maintain the required temperature without injury due to concentration of heat. Combustion heaters shall not be used during the first 24 hours unless precautions are taken to prevent exposure, of, the concrete to exhaust gases which contain carbon dioxide. Concrete shall not be placed against forms exposed to heating by the unless the temperature of the forms is first cooled to s 90°F. 3.02 PLACEMENT Placement shall conform to ACI 301, Chapter 8 'Placing", ACI 304R; "Guide of Measuring, Mixing, Transporting and Placing Concrete," ACI 306 "Recommended Practice for Cold Weather Concreting", ACI 305 "Recommended Practice for $ot Weather Concreting" and ACI 309, "Standard Practice for Consolidation of Concrete". 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 percussion 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 fmishing 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 minimi a 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 held at the bottom of Robert Benson Dam 03310-8 Structural Concrete lift for 5 to 15 seconds. 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 Robert Benson Dam 03310-9 Structural Concrete 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. The use of an evaporative retardant requires review and approval by the ENGINEER.

PART 2 PRODUCTS (Not Applicable) PART EXECUTION 3.01 SURFACE PREPARATION Robert Benson Dam 03320-1 Construction Joints Q. How much filter material is going to be required over the toe drain pipe? I see that the detail shows it stopping a minimum one foot below surface grade, is there a maximum depth from the surface to the top of the filter material, or a minimum height of the filter material over the pipe? A. No. The filter material shall be installed per the detail 3/12 on sheet C11. The filter material height over the top of pipe will vary according to the pipe and surface grade. However, at no point shall there be less than 1-foot of filter material over the drain line. Q. Are there to be pipes Installed from the sand filter collar to the headwall? Is the sand to continue as pipe bedding from the collar to the headwall? How does any water which is collected in the sand collar get out of there? A. Please see the revised Sheet C 9 - Principal Outlet Works Plan and Profile for the design of the sand drain for the cutoff wall. The drain shall consist of ASTM C-33 sand, installed a minimum of 12 inches around both the steel and the PVC pipes. This sand drain shall connect to the gravel pack around the toe drain, which will drain all flows to the concrete headwall at the outlet of the steel pipe. Please include the material and installation costs of this sand drain in the respective Bid Schedule line items for the "Principal Outlet - 24- inch C200 Steel Pipe — Item 16," and 'Irrigation - 10-inch C900 PVC Irrigation Pipe — Item 26." Cl. Is the concrete sand cutoff wall to be installed to a width which provides one foot into undisturbed soil to an elevation of 6 ft above the tallest pipe or should it be bid as 11 ft wide square per the drawing? A. The concrete sand cut off wall should be installed to a width which provides one foot into undisturbed soil to an elevation of 6 ft above the tallest pipe. The quantity of sand listed in the Bid Schedule reflects this requirement, with the assumption that the trench extends 1-foot outside of the concrete encasement, with the sand wall extending a further 1-foot into undisturbed ground. A revised Sheet C9, showing the true length of the wall is attached. Q. At what point does the pipe bedding detail begin and end and on which pipes is this required? A. The pipe bedding detail is only applicable to the irrigation pipeline from STA 0+00 to approximately STA 1+60. Please refer to sheet C10. Q. Does the CY of rip rap include the rip rap bedding material? A. No. The bedding material and geotextile fabric shall be included in the unit cost of the riprap. The quantity of bedding and fabric may be estimated from the plan and sections of the riprap areas, and Details 3/13 and 4/13. Q. If there is variation in the earthwork quantities from the bid documents that can be documented by surveys, will this be considered as unit price payment or will this be a lump sum per the drawings the way the measurement and payment spec reads? A. The specification (Section 01270 - Item 14) and Addendum No. 1 are clear with respect to how the excavated material will be measured and paid for. The item is not listed anywhere as lump sum. The foregoing prices shall include all labor, materials, transportation, shoring, removal, dewatering, overhead, profit, insurance, etc., to cover the complete Work in place of the several kinds called for.

The reservoir is retained by the Fairport dam (DAM ID 040123), a Class II earthfill dam. In 1973 the State Engineer's Office (SEO) placed a restriction on the storage level in the reservoir, followed by further restriction in 1987. An inspection and subsequent letter in 1996 documented the poor condition of the dam and indicated that significant improvements would be required to improve the safety of the dam. We understand a breach order may be imposed by the SEO if action is not taken to mitigate the current condition. The existing dam consists of two segments separated by a grass spillway: a homogeneous, earhfill dam on the east side of the reservoir and an informal clay dike on the south and southeast sides of the reservoir. The dam is approximately 520 feet long and 12 feet wide at the crest, with a maximum section (measured at the outlet works) of about 11 feet. The upstream face of the dam has a slope of about 3h:Iv, but it is steeper in some places. The downstream face is estimated at about 2h:ly, and also has areas that are as steep as about lh:ly. A masonry outlet works consisting of a vertical shaft, a clay pipe and a control valve is located hear the midpoint of the dam. The clay dike is 3 to 10 feet wide, tip to about 6 feet high, and about 400 to 500 feet long. It is overgrown with trees, shrubs, and grass over most of it's length. The current water level of the reservoir is about 4996 feet. Vegetation consists of grasses, shrubs and small trees on the dam and surrounding ground. Large cottonwood trees are located nearby, and wetland species / predominate at and above the current water level. College Avenue (U.S. Highway 287) is located 2 immediately west of the reservoir. City owned land (Pelican Marsh Natural Area) is to the east between the reservoir and Lemay Avenue. A residential subdivision, Provincetowne, is located to the northeast, and rural residential property is located to the north and south. The general site location, the configuration of the existing dam and dike, and the locations of borings and test pits are shown on Figure 1. 4.0 PREVIOUS INVESTIGATION Parsons & Associates conducted a feasibility study for the reservoir site in 1996. That study examined several alternatives for the reservoir, but non of the options were constructed. The Parsons report referenced a geotechnical investigation for the dam performed by Chen & Associates in 1985. As part of their investigation, Chen drilled four borings in the main embankment and hand augered two additional borings in the dike. The results of the Chen investigation were considered in the investigation planning, analysis, and opinions presented in this report. 5.0 PROPOSED CONSTRUCTION The City of Fort Collins is considering several alternatives for the area that will address requirements of the State Engineer's office regarding the dam and consider the preferences of residents in the vicinity. The alternatives considered in the planning ofthis investigation were: • the rehabilitation of the existing dam such that restrictions of the SEO can be removed and the current reservoir can be maintained or a higher water level developed; or • a less extensive dam that can be constructed to retain a smaller area with open water, as well as maintain or improve wildlife habitat, wetlands, and vegetative d iversity. These two alternatives are discussed below. Although both are classified as small dams according to the USER criteria, they are frequently described herein as the large dam alternative and the small dam alternative in a relative sense. 3 1 ) 5.1 Class U Dam Alternative The larger dam alternative would allow the impoundment of about 280 acre feet of water on 41 acres, with a maximum depth estimated at about 8 feet. High water level would be 4999 feet. The existing dam would need to be reconstructed, and a new outlet works and spillway added. The new dam would have a crest elevation of about 5,004.5 feet, and would extend from a similar elevation near the northeast corner of the reservoir area to the southeast, then curve west through the area currently occupied by the informal dike to connect with the existing higher topography to the west. The preliminary design is for a homogenous clay embankment approximately 1,762 feet long and 14 feet wide at the crest. It would have a maximum section of i I feet measured from the crest to the ground surface at the outlet works on the downstream face. The slope of the upstream dam face would be flattened and reconstructed at a 3h:ly slope using borrow material i from Pelican Marsh Natural area to the east. Using the same borrow source, the crest would be widened to 14 feet and the downstream face reconstructed at a 2.5h:1 v slope. The crest would be surfaced with aggregate base course and would slope towards the reservoir at 2 percent. The spillway would be located near the southeast corner of the existing dam. The downstream face i would be planted with grass, and the upstream face would be protected with rip rap, revetment, or similar materials. A filter and drain would be constructed at the toe of the downstream face for about 600 feet of the length of the dam where the topography is lower than the proposed water surface. Design and construction recommendations are presented below in section 9. Figure 2 shows the approximate limits of the large dam alternative and a section north of the existing outlet works. 5.2 Small Dam Alternative The smaller dam alternative would retain approximately 162 acre feet of water on 16 acres, with several smaller ponds interspersed with wetland and riparian areas. The spillway and outlet works would be reconstructed, and the existing dam would be lowered to a crest elevation of 5002 feet. The existing upstream and downstream faces would maintain their existing slopes, but would be regraded and recompacted. The water surface would remain lower than the existing ground surface adjacent to the dam, and a new drain is therefore not proposed. The smaller alternative would require extensive grading and revegetation in the former reservoir area. Figure 3 shows the proposed configuration of the small dam alternative. 4 / 6.0 SUBSURFACE Subsurface conditions were investigated by drilling three test holes in the existing dam, two test holes in the dike, and a boring in the spillway area. Three test pits were also excavated in the Pelican Marsh Natural Area to the east of the reservoir to evaluate that area as a potential borrow source. The approximate locations of the borings and test pits are shown on Figure 1. Logs of the borings, including results of field penetration resistance tests, are shown in Appendix A. Soils encountered were silty clay fill, natural silty and sandy clay, and claystone bedrock. Samples obtained during drilling were returned to our laboratory and visually examined by a geotechnical engineer. Laboratory testing on comparatively undisturbed samples included natural moisture content and dry density, swell -consolidation, unconfined compressive strength, direct shear, Atterberg limits, pinhole dispersion, water-soluble sulfates, and permeability tests. Samples from the borrow area were classified using index tests, and additional testing was performed on samples proposed for use as embankment materials, including standard Proctor compaction, swell/consolidation, remolded permeability, unconfined strength, and direct shear. Results of laboratory tests are presented in Appendix B and summarized on Table B-I. The soils are described below. 6.1 Clay Fill Our borings in the existing dam and dike encountered 4 to 9 feet of silty, moderate to high plasticity clay fill. Standard penetration resistance tests indicate blow counts of 10/12 to 23/12 in the fill, indicating generally a very stiff consistency. Laboratory densities ranged from 86 pcf (MFG-1 at 2.5 feet) to 116.4 pcf (MFG-5 at 4 feet). The average dry density was 103.9 pcf (97 percent of the standard Proctor maximum dry density determined for a sample of the borrow material in the laboratory). Moisture content of the fill ranged from 9 to 22 percent. Atterberg limits testing indicated liquid limits of 39 to 54 and plastic indices of 26 to 40. Samples tested had 68 to 93 percent silt and clay sized particles (passing the number 200 sieve). The permeability of a comparatively undisturbed sample (obtained from a California liner) at a depth of 4 feet in the existing dike was 7.1 x 10-8 cm/sec. Unconfined strengths of 2,700 and 6,200 psf were measured at a depth of 2.5 feet. Direct shear tests on a sample of the fill at 4 feet indicated peak strength values for c and phi of 391 psf and 36 degrees, and ultimate strength values for c and phi of 178 psf and 30 degrees. A sample from a depth of 2.5 feet swelled 6.9 percent when wetted after application of a 500 psf pressure. Water soluble sulfates were measured at 0.11 wi �i percent in a sample indicating a severe potential for attack of concrete exposed to site soils. A pinhole dispersion test (ASTM D 4647) performed on a sample of the existing embankment (MFG-2 at 4 feet) did not indicate a potential piping concern for the site soils. 6.2 Natural Clay And Borrow Soil A two foot thick tense of natural, sandy clay was encountered below the fill in MFG-2. Five to 8 feet of weathered claystone was encountered in three of the borings. The upper surface of the bedrock was also weathered to a very stiff clay in all three of the test pits. A sample of the in -situ weathered bedrock from MFG-4 at 9 feet had a measured coefficient of permeability of 1.7 x 10-s cm/sec. The natural clays and weathered bedrock from the borrow area east of the reservoir site were combined and tested for comparison with the soils that make up the existing embankment. Atterberg limits tests showed liquid limits of 39 to 55 and plasticity indices of 25 to 40, with 65 to 85 percent passing the number 200 sieve. A sample remolded to approximate embankment conditions (95 percent compaction at 1 percent above optimum moisture content had a 0.2 i percent swell potential under a 1000 psf pressure, a coefficient of permeability of 2.8 x 10'e cm/sec, and an unconfined compressive strength of 3100 psf. A direct shear test indicated peak strength values for c and phi of 320 psf and 22.4 degrees, and ultimate strength values for c and phi of 302 psf and 22.5 degrees. These results and our observations indicate the available borrow soils located in Pelican Marsh natural Area east of Robert Benson reservoir are similar to the existing embankment materials and are suitable for use as fill for an enlarged dam. 6.3 Bedrock Comparatively unweathered claystone bedrock of the Pierre Shale was logged at depths of 8 to 12 feet below the current ground surface in all the exploratory borings. Sandstone lenses or very sandy claystone lenses were encountered in 3 of the borings, but claystone predominated. Test pits did not encounter unweathered materials to the depth excavated. A claystone sample tested had a liquid limit of 56 and a plasticity index of 38, with 96 percent passing the member 200 sieve. Another sample tested swelled 3.2 percent when wetted with an inundation pressure of 1000 psf. A sample of the weathered bedrock from MFG-4 at 9 feet had a measured coefficient of permeability of 1.7 x 10-8 cm/sec. Borings indicate that weathered and comparatively l3 unweathered claystone would be the foundation for a new or enlarged dam at the site. Test results indicate these materials are suitable as a dam foundation. 6.4 Water Free water was not encountered in any of the borings or test pits. Moisture content of the laboratory samples were generally several percentage points below the anticipated optimum moisture content of the clay soils, and bedrock samples were logged as slightly moist to moist. These conditions suggest that Robert Benson reservoir is likely the result of runoff or other perched water that has flowed into the area and does not flow out rather than groundwater that would naturally surface in the area. This may be an important distinction in planning the j vegetation and potential success of the area as a wetland if the dam is breached or removed. For i construction planning, wet areas and soft unstable soils are likely in the reservoir area and in excavations such as that needed for the outlet structure. 7.0 STABILITY ANALYSES The upstream face of the existing embankment has a variable slope as steep as 1h:ly in some areas, according to a previous investigation (Chen, 1985). The downstream face is also variable and includes areas where erosion has resulted in steep slopes. Both slopes will require mitigation during construction that is discussed below in section 9. For our analyses of the existing slopes we used the maximum section of the embankment measured near the outlet works (see Figure 2). Using soil profiles and strength parameters conservatively estimated from our investigation, we modeled the existing embankment using SLOPE/W software by Geoslope International and Spencer's method. We used a 2.75h:ly slope for the upstream face and a 2.5h:ly for the downstream face. Soil properties used in the analyses are summarized below: Table 1.

Calculated minimum factors of safety are presented below in Table 2. Table 2. Calculated Safety Factors, Existing Embankment Condition Calculated Minimum Safety Factor Upstream Face Downstream Face Existing 1.85 1.75 High Water Surface 1.46 1.50 Rapid Drawdown 1.37 1.50 These data indicate the slope is stable in the current configuration with a low water level, however it does not meet minimum safety factor requirements for high water level. Further, the dam and dike do not meet current dam safety regulations or commonly accepted design guidelines, and the condition of the dam has been reported as unacceptable by the SEO. For the reconstruction and enlargement to meet current standards for a Class II dam, we modeled the upstream face as 3h:ly and the downstream face at 2.5h:Iv. The crest was widened to 14 feet and a toe drain and filter were added. We assumed the existing embankment condition will be repaired and borrow soils with properties similar to those of the existing soils will be used to construct the new slopes. We used a crest elevation of 5004.5 feet. For the high water condition we assumed 3 feet of freeboard. We modeled the water as a no -strength material having a unit weight of 62.4 pcf. For seismic loading we used a pseudo -static analysis with a coefficient of 0.05. Calculated minimum safety factors for the proposed design are presented in Table 3 below. Printouts from the software analyses are included in Appendix C. Recommendations for embankment rehabilitation and construction are presented in section 9 below. M Table 3.

For our analysis, we assumed a maximum water level three feet below the dam crest at the maximum section. A coefficient of permeability of 4.95 x 10-6 cm/sec and a permeability function developed by MFG for the Pierre Shale in the Colorado Front range were used to model seepage through the embankment. The analysis indicates the reconstructed embankment and proposed filter and drain will control internal erosion and seepage as required. Output from the computer model is included in Appendix D. 9.0 DESIGN AND CONSTRUCTION RECOMMENDATIONS Both alternatives proposed for Robert Benson Reservoir will rely on the reconstruction of the existing homogeneous clay earthfill dam. The following design and construction recommendations are generally described in terms of the larger, class 11 dam alternative. However, stripping, excavation and fill procedures, erosion protection and other recommendations should be assumed to apply to the smaller dam alternative as well, unless specifically noted. 9.1 Foundation and Embankment Preparation The existing embankment must be stripped of all topsoil, organics, and other deleterious materials and thoroughly inspected for evidence of cracking, poor soil condition, existing rip rap zones, organic material, roots or other unacceptable conditions. We assumed a minimum of 6 to 12 inches of existing soil would be removed and stockpiled for reuse as topsoil. The upper one foot of existing soil below that should be scarified, processed to a uniform condition, examined by a 9 geotechnical engineer for suitability, and recompacted if it is acceptable. The bases of fills should be moisture conditioned to within I percent below to 2 percent above optimum moisture content and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D698). Areas where unsuitable material are encountered should be over -excavated to a depth sufficient to completely remove the unacceptable soil, then the area should be processed as described above. hi the area of the informal dike, tree, stump, and root removal will be an important component because of the abundance large, mature trees and other vegetation. If fill is to be placed on slopes greater than 2 percent, the fill should be keyed into the existing slope at least 1 foot deep and eight feet wide. The Class II dam alternative will have a downstream slope of 2.5h:ly and an upstream slope of 3h:ly, and a crest width widened to 14 feet. The smaller dam alternative will have the upper several feet removed to lower it to the design elevation, but the slopes will not be modified except by the re -grading and recompaction described above. Both dam alternatives will have emergency spillways designed and constructed by others. Anticipated grading of the spillways, preliminary embankment grading, and dam cross sections are shown on Figures 2 and 3. The City owned property east of the reservoir site is an acceptable source of borrow for the proposed embankment. The topsoil should be stripped at least 6 inches deep and the area examined by a geotechnical engineer to confirm the soils are lean clays similar to the existing embankment soils. Materials found in our test pits can be excavated using conventional heavy- duty construction equipment. If soil variability or deeper than anticipated excavations encounter cemented sandstone lenses in the bedrock, specialized excavation equipment or techniques may be needed. If such conditions are encountered, the material may not be suitable as fill for the embankment. Fill should be moisture conditioned to between 1 percent below and 2 percent above optimum moisture condition and compacted in 8 inch maximum loose lifts to at least 95 percent of standard Proctor maximum dry density as determined according to ASTM D 698. If soft, unsuitable, or yielding materials or areas are encountered during this process, they should be removed and replaced with suitable fill. Fill placement and compaction activities should not be conducted when the fill material or subgrade is frozen. The fill placement and compaction should be observed and tested by a qualified geotechnical engineer or their designated representative. IR If excavations are made into the reservoir area upstream of the dam, soft, wet soils or perched water may be encountered. We recommend test excavations in these areas several weeks before the construction to determine if wet or unstable conditions are likely. If water or soft, wet soils are encountered, we recommend temporarily lowering the water level in these areas to at least 3 feet, and preferable 5 feet below the ground surface prior to constriction to reduce potential instability. Dewatering can be accomplished by excavating a trench that slopes to a sump where water can be removed by pumping. Soft, wet soils or free water may also be encountered during excavation to replace the outlet piping. If soils are to be imported for use in this project, the properties should be thoroughly evaluated for compatibility and consistency with the design assumptions in this report. Samples of any soils proposed for importation should be provided to us for examination, testing, and verification engineering properties prior to importing them to the site so that we can provide our opinion as to the suitability of the material for its intended use. 9.2 Drain The class 11 dam alternative will require a drain to maintain seepage conditions below the toe of the proposed embankment. For our preliminary design and estimating purposes we assumed a 6 inch diameter pipe and a drainage envelope that extends a minimum of 2 feet above and to each side of the pipe, with at least 6 inches of drain rock below the pipe as bedding. The drain rock should be surrounded by a two foot thick filter layer extending up and away from the drain rock at a slope of lh:ly. Recommended drain rock and filter gradations are presented in Table 4 below. Table 4.

If yes list agency name. Rev 10/20/07 Section 00420 Page 1 The drain pipe should be placed 6 feet upstream from the toe of the proposed downstream slope. It should begin where the downstream toe of the embankment intersects the 5001 foot elevation and slope down at 1 percent to a suitable outfall to the south. The smaller dam alternative would result in a water surface elevation that is lower than the existing ground in all areas. Therefore we do not anticipate a drain would be required for that alternative. 9.3 Excavations Deep excavations are not anticipated. However, trenching may be required to remove and reconstruct the outlet works. If trenches are excavated, the sides should be sloped or shored to meet local, State and federal safety regulations. Based on our investigation and OSHA standards, we believe the site soils are predominately stiff to very stiff clays with occasional sand lenses that will classify as Type C soil, according to OSHA standards. Type C soils require a maximum slope inclination of 1.5:1 in dry conditions. Excavation slopes specified by OSHA are dependent upon types of soil and ground water conditions encountered. The contractor's "competent person" should identify the soils encountered in the excavation and refer to OSHA standards to determine appropriate slopes. Stockpiles of soils and equipment should not be placed within a horizontal distance equal to one-half the excavation depth, from the edge of excavation. Excavations deeper than 20 feet should be braced or a professional engineer should design the slopes. Temporary slopes (slopes for excavations that will remain open for less than two weeks) should not be steeper than 1.5 to 1 (horizontal to vertical) in dry soil conditions. If water is encountered during excavations, slopes will cave to flatter angles and bracing, shoring, de - watering, and/or other techniques may be necessary. 9.4 Slope and Erosion Protection Recommendations for preparation of the ground in fill areas were described above in Section 9.1 of this report. Slopes and other areas that will need to be protected from erosion, such as the spillway, should be similarly prepared. A sand layer at least 12 inches thick should be placed and compacted in areas to receive rip rap. Rip rap should be 18 inches nominal diameter, if used. If a manufactured product such as revetment is used, manufacturers recommendations should be followed for base preparation and product installation. 12 We assumed the downstream face of the embankment will be seeded and will not require additional erosion protection. We recommend the dam crest slope slightly towards the reservoir on the order of 2 percent to limit the potential for erosion on the less protected downstream face i of the dam. 9.5 Outlet Works We assumed the existing outlet vault, pipes and valve will need to be removed and a new system designed and constructed as part of the project. Erosion protection will be needed upstream and downstream of the outlet structure. If soft or unsuitable soils are encountered they should be removed and replaced during the construction. Pipe should be properly bedded; however low permeability barriers should be installed at intervals (two minimum) along the pipe alignment. The water barriers should extend at least 2 feet into the surrounding clay soils on all sides of the pipe and trench to reduce the potential seepage through the trench. The cutoff wall can be constructed of low permeability clay soil compacted to approximately 98 percent of standard Proctor maximum dry density (ASTM D 698) and within 1percent below to 2 percent above optimum moisture content, or it can be constructed by excavating a trench of the proper dimension and filling it with concrete. We do not recommend controlled low strength material (CLSM or "flow fill') for this application because the permeability can be much greater than that of the surrounding soil. 10.0 PRELDONARY COST ESTIMATES MFG prepared preliminary cost estimates for earthwork associated with the class II dam and the smaller dam alternative. These estimates are suitable for preliminary planning and budgeting purposes. Spreadsheets detailing anticipated costs are presented in Appendix E. 11.0 LUMTATIONS Our borings were spaced to obtain a reasonable picture of subsurface conditions. Variations in the subsoils not indicated in our borings are possible. This report was prepared from data developed during our field exploration, laboratory testing, engineering analysis and experience with similar conditions. Our calculations and designs were based on assumptions of ground conditions, proposed scopes of work, and contractor capabilities and methods. Our representative should observe the excavation of the embankment to look for evidence that would indicate 13 differences in subsurface conditions from those described in this report. If any of the conditions change, or if information becomes available that would alter our assumptions or our calculations, the opinions presented in this report should be considered invalid until we have been contacted to review our recommendations.. We should review plans and specifications during the design, and should observe the construction to confirm soils are as we anticipated from our borings. Placement and compaction of compaction fill, backfill, subgrade and other fills should be observed and tested by a representative of our firm during construction. 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.

Her first position was sales, customer service, displays and store maintenance. Additional responsibilities were later added to include opening, closing and assistant manager. Over the past three years she has initiated a complex computer system which included accounts payable, accounts receiveable, general ledger and inventory control. All tasks that were assigned were performed at a very satisfactory level. We found her timely, percise, punctual, honest and always having concern for our business. We would recommend Sandy for employment in any of the above related areas. If the opportunity presented itself for re-employment with our company a position would be available. If you have further questions about Sandy, please feel free to contact me at the above address or phone (517) 362-3437.

Can the dam be breached to install the outlet works and dewater the site? A. Yes. The dam can be breached at the location of the new outlet works. However, the Contractor is responsible for all construction dewatering, including permits as well as a stormwater management plan (SWMP) and permitting with the State of Colorado. The trench location excavated for the new outlet works must meet current OSHA requirements for trench safety. Upon completion of the outlet works installation, the Contractor must restore the dam to its original condition replacing the material in kind according to the Embankment specifications included in the contract documents. This work shall include "keying" in the embankment into the undisturbed dam cross section. The keyed embankment shall be a minimum of every 3 vertical feet and extending 4 feet into the dam cross section on either side of the trench. The Trench Backfill Specifications in Section 02320 are not applicable to this portion of the work and shall not be considered by the Contractor to be a valid approach to restoring the dam cross section. 0. Is excavation of the pipe trench material incidental to installation of the various pipe items included in the project? A. Yes. 0. Can the pipe trench (principal outlet) material be reused on site? A. Yes, if it is suitable and meets the specification section for Embankment. The Contractor shall reuse all suitable dam core fill material within the breached section to re-establish the design lines and grades. 0. Will the city provide the construction surveying and geotechnical testing? A. The city will provide the geotechnical testing through a standing contract with CTL Thompson. This work will be coordinated by our on -site resident engineer. Construction surveying needed to establish the lines and grades shown on the drawings is the Contractor's responsibility. This work is to include setting the survey monuments identified in the plans. Please refer to Section 01720. 0. What is the grade tolerance for dam earthwork? A. The final grade tolerance for all earthwork on the project shall be +/- 0.10 feet. This specification modifies Section 02315, Part 3.01 A. All structural components of the project including construction of the spillway sill must be built to within A" of the lines, grades and elevations shown on the plans. 0. What testing is required for the pipe work on the project? A. Please refer to Section 02615 for installation requirements for the 24-inch steel outlet pipe. The Contractor shall note that the 24" outlet pipe will include single lap welded joint or single weld butt joints. The joint welds will only be visually inspected by the resident engineer. The pipe shall be coated to prevent moisture corrosion and the Contractor shall provide for field joint repair after welding has been completed. Testing parameters shown below shall be completed prior to concrete encasement of either outlet pipe. The Contractor shall provide all personnel and equipment necessary to perform the hydrostatic test. This shall include water, taps, plugs, valves and/or blind flanges necessary to pressurize the pipeline. The pressure test shall occur over a 2 hour period where the pipeline must maintain a minimum pressure of 50 psi. The contractor shall provide a means of measuring the water lost over this time.
