Dear Drew: This letter is in repsect to our meeting on July 29, 1987, with Jerry Chodil and Larry Van Deventer of Ball, Monty Force of KKBNA, and Pete LaClair of Hensel Phelps concerning the proposed CRC site and off-site road improvements to Weld County Road 7. As you are aware, Weld County Road 7 will provide access to the proposed site. I will summarize our discussion of that meeting, responsiblity of road improvements, and introduce a preliminary estimate of cost. Existing Weld County Road 7 from Weld County Road 38 to the BASD-CRC access (1/4 mile south of Weld County Road 42) is a gravel road with a degree of clay and silt. Because of this clay, during periods of rain or wet conditions the road becomes slippery and travel becomes difficult. Although the projected average annual daily traffic (AADT) for the proposed BASD-CRC is low (17) , safe travel is still a must and road improvement is necessary due to the hardware and fluids being transported to the site. The existing AADT for Weld County Road 7 is approximately 70. Using these AADT values it can be calculated that the percentage use of the county road by the proposed BASD-CRC is 20%, and therefore BASD' s share of responsibility is also 20%. A preliminary cost estimate for 1.75 miles of road improvement is approximately $80,000 to $100,000. A detailed soil study and design must be completed to -determine exact specifications so that the cost of road improvements can be better estimated. It is our understanding that the actual construction of improvements would be the responsibility of BASD, and that construction would occur prior to occupancy of the CRC. We are aware that the Weld County. Commissioners will make the final decision on the off-site road improvement agreement. 871088 !,f 1-' Drew Scheltinga, County Engineer Weld County August 5, 1987 Page Two If there are any conflicts or misunderstandings of this letter, please contact me.

Scheltinga, County Engineer &S4-. Subject: Ball Aerospace COZ Z-435:87:4 and PUD Plan S-280:87:7 The application indicates that Weld County Road 7, which will provide access to the site, is very sparsely traveled. This comment is correct particularly because the bridge over the Little Thompson River approximately one mile north of the site has been out for approximately four years. There are no residences along this stretch of Road 7 and agricultural traffic is minimal because wheat is being raised on the adjacent lands. - Therefore, Weld County's maintenance efforts on this stretch of road have been minimal. Two years ago I had occasion to ride on this stretch of road in a passenger van, during wet weather conditions with the Board of Weld County Commissioners. The roadbed was extremely slippery because of the underlying clay soils. Because of the steep grades along the access we had great difficulty traversing Road 7. Although the traffic projections for this site are relatively low, the 1-3/4 mile of Weld County Road 7 from Weld County Road 38 to the side entrance will not provide safe access during inclement weather. The soils report in the PUD application material indicates the internal roads should be constructed with 18" of gravel sub base and 6" of gravel base. Weld County Road 7 must be constructed to the same standard to provide 365-day a year access. ' An off-site road improvements agreement should be executed between the applicant and the Board of Weld County Commissioners prior to the recording of the final PUD plat.

The investigation was carried out by means of test borings and laboratory testing of samples obtained from these borings. • SITE INVESTIGATION The field investigation, carried out on May 7th, 12th & 20th, 1987, consisted of drilling, logging and sampling 1 thirteen (13) test borings. The locations of the test borings • are shown on the Test Boring Location Plan included in Appendix A of this report. Boring logs prepared from the field logs are also presented in Appendix A. These logs illustrate the soils encountered, depth of sampling and } elevations of subsurface groundwater at the time of our investigation. All borings were advanced with a four-inch diameter, continuous-type, power-flight auger. The test borings were drilled to depths of five (5) to thirty (30) feet. The drilling operations were performed under the supervision of a geotechnical engineer from Empire Laboratories, Inc. , who (1) S made a continuous visual observation of the soils encountered. Additional test borings will be performed on the south portion of the site when this area becomes accessible. A visual inspection of the site was made by an engineering geologist from Empire Laboratories, Inc. on May 21, 1987. SITE LOCATION AND DESCRIPTION This site is located on the east side of Weld County Road #7 and south of Weld County Road #42, north of the Town of Mead, Colorado. More particularly, this site may be des- ; cribed as a tract of land situated in the west 1/2 of Section C 27, Township 4 North, Range 68 West of the Sixth P.M. , Weld County, Colorado. The site is open rolling agricultural land. Portions of this site are vegetated with wheat while other areas are 1 cultivated. A gully exists at the southwest corner and at the northwest corner of this site. This property slopes gently downward toward the north and exhibits good positive drainage toward the north. LABORATORY TESTS AND EXAMINATIONS Laboratory testing and examination were performed on samples obtained from the test borings in order to determine the physical characteristics of the soils encountered. Moisture contents, dry unit weights, unconfined compressive strengths, water soluble sulfates, swelling potentials and (2) 1 871088 Atterberg limits were determined. A summary of the test results is included in Appendix B of this report. Consolidation characteristics and "R" values were also deter- mined, and curves showing this data are also included in Appendix B. SOIL AND GROUNDWATER CONDITIONS The soil profile at the site consists of strata of materials arranged in different combinations. In order of' increasing depth, they are as follows: 1 ( 1) Topsoil: The site is overlain by a layer of silty [ topsoil approximately six (6) to twelve (12) - inches thick. The upper four (4) to six (6) yi inches of topsoil has been penetrated by root growth and organic matter and should not be used 1 as backfill or foundation bearing. (2) Sandy Silty Clay: Brown sandy silty clay with varying amounts of each component underlies the Y 9 P topsoil and extends to the underlying bedrock at depths of four (4) to eighteen (18) feet. 1 This clay stratum exhibits low bearing charac- teristics and consolidates readily upon loading. This stratum exhibits low swell potential . (3) Siltstone Sandstone Claystone Bedrock: Inter- bedded layers of siltstone sandstone and claystone bedrock exists beneath the clay stratum and extends to the depths explored. The upper one . (3) 871088 ( 1) to five (5) feet of bedrock is weathered. The firm bedrock exhibits high bearing charac teristics. The siltstone claystone bedrock exhibits moderate swell potential. (4) Groundwater: At the time of our investigation, t no free groundwater was encountered to the depths explored. Water levels in this area are subject to change due to seasonal variations and irri- gation demands. In addition, surface water may percolate through the upper subsoils and become trapped on the relatively impervious bedrock stratum, forming a perched water condition. '1 RECOMMENDATIONS AND DISCUSSION It is our understanding that five (5) concrete cast-in- place research buildings, a control building and an equipment e q pment storage building will be constructed on this site. Four (4) of the research buildings are proposed to be thirty (30) feet high and the centrally located research building is proposed to be sixty (60) feet high. These structures are designed to have partial basements and to be equipped with machines up to ninety (90) kips in weight, some of which will vibrate. The control building and equipment building are proposed to be one-story frame structures with slab on grade construction. 1 (4) 1 871088 Geology The proposed site is located within the Colorado Piedmont section of the Great Plains physiographic province. The Colorado Piedmont, formed during Late Tertiary and Early Quaternary time (approximately sixty-five million (65,000,000) years ago) , is a broad, erosional trench which separates the Southern Rocky Mountains from the High Plains. Structurally, the property lies along the western flank of the Denver Basin. During the Late Mesozoic and Early Cenozoic Periods (approxi- mately seventy million (70,000,000) years ago) , intense tectonic activity occured, causing the uplifting of the Front 1 Range and the associated downwarping of the Denver Basin to the east. Relatively flat uplands and broad valleys charac- - hi terize the present-day topography of the Colorado Piedmont in this region. The site is underlain by the Cretaceous Pierre Formation. The Pierre shale is overlain by residual and alluvial clay soils of Pleistocene and/or Recent Age. Bedrock outcrops were not noted at the site. The bedrock underlies the site at depths of four (4) to fifteen (15) feet below the surface. The regional dip of the bedrock in this area is slight and in an easterly direction. From a struc- 4 tural standpoint, the property should be relatively stable. The majority of the site consists of relatively flat to gently-sloping topography. The headwaters of several small intermittent streams are located in the northwest, southwest, east-central and northeast portions of the site. These are gently to moderately sloping areas exhibiting little or no (5) 871088 erosion. All but the southwest drainage are planted in winter wheat. The southwest drainage is vegetated with native grass, and part of this area has been used as a dump. The property lies within the drainage basin of the Little Thompson River. It is suggested that construction not be placed within these drainage areas or that the areas be filled and regraded to direct drainage around them. It is our understanding that the proposed construction will not be placed in these natural drainages. Due to the gentle slopes over the majority of • the site, geologic hazards due to mass movement, such as land - 1 slides, mudflows, etc. , are not anticipated. With proper site grading around proposed structures, erosional problems at the site should be minimal. Geological conditions at the Isite are such that economic deposits of sand and gravel, quarry rock, limestone and coal are not anticipated to economic depths. Radiation hazards at the site are anti- cipated to be minimal. The Pierre formation is not known to contain extensive radioactive materials. However, this can only be verified by field or laboratory tests and testing of structures after they have been completed. Site Grading & Utilities It is recommended that the topsoil containing roots and organic matter, which extends to a depth of approximately four (4) to six (6) inches, be removed from the area of the proposed building. This topsoil should then be stockpiled for future landscaping use. The subgrade should then be scarified to a depth of six (6) inches and recompacted at (6) 1 871088 ' or near optimum moisture to ninety percent (90%) of Standard Proctor Density ASTM D 698-78. (See Appendix C.) Where this subgrade compaction cannot be obtained due to saturated or unstable soil conditions, the subgrade should be stabilized by the use of granular pit-run material or by the use of geo- textiles. On-site soils or granular soils approved by the geotechnical engineer are suitable for use as fill in the proposed building areas. All fill underlying the building . areas should be placed in layers not exceeding eight (8) inches in thickness and compacted at or near optimum moisture to a minimum of ninety-five percent (95%) of Standard Proctor Density ASTM D 698-78. In computing earthwork quantities, an estimated shrinkage factor of eighteen percent ( 18%) to twenty-three percent (23%) may be used for the on-site clays and silts compacted to the above-recommended density. Utility trenches dug four (4) feet or more into the upper subsoils should be excavated on stable and safe slopes in accordance with OSHA regulations, or the excavations should 1 be properly shored. All piping should be adequately bedded for proper load distribution. Backfill placed in utility trenches in open and planted areas should be compacted in uniform lifts at optimum moisture to at least ninety percent (90%) of Standard Proctor Density ASTM D 698-78 the full depth of the trench. The backfill placed in utility trenches under building and paved areas (7) 871088. 4 should be compacted at or near optimum moisture to at least ninety-five percent (95%) of Standard Proctor Density ASTM D 698-78. Addition of moisture and/or drying of the subsoils may be needed for proper compaction. All fill should be inspected by the geotechnical engineer, and field density tests should be taken under the supervision of the geotechnical engineer to verify that the specified compaction requirements are attained in the field. Foundations Based on the low bearing characteristics of the upper clays on this site and the magnitude of the loads of the cast-in-place research structures, it -is our opinion that these structures should be supported by drilled pier founda- tion systems. Drilled piers are also recommended to support large machines creating vibrations or which can only tolerate minimal differential settlement. Machine foundations should be structurally independent of floor slabs. It is recom- mended that piers be drilled into the bedrock stratum and that structural grade beams span the piers. These piers would support the structure through friction and end bearing. lThe piers should be straight-shaft and should be drilled with plumb tolerances of one and one-half percent ( 1 1/2%) relative to the length of the pier. All piers should have minimum ten (10) foot lengths. They should be drilled a minimum depth of five (5) feet into the firm bedrock stratum and when founded at this level may be designed for a maximum allowable end bearing pressure of fifteen thousand ( 15,000) (8) 871088 pounds per square foot. It is estimated that a skin friction of one thousand five hundred (1 ,500) pounds per square foot will be developed for that portion of the pier embedded more than three (3) feet into the firm bedrock stratum. We recommend that piers be designed for a minimum dead load of five thousand (5,000) pounds per square foot to counteract swelling pressures which will develop if the subsoils become wetted. Skin friction from additional embeddment into the firm bedrock may be used to resist uplift if necessary. To help provide the required skin friction, the sides of the pier drilled into the bedrock stratum should be roughen- ed. All piers should be reinforced for their full length to resist tensile stress created by swelling pressures acting on the pier. It is recommended that piers be a minimum of eighteen (18) inches in diameter to facilitate cleaning, dewatering and inspection. . It is strongly recommended that the geotechnical engineer be present during the drilling operations to: (1) identify the firm bedrock stratum, (2) assure that proper penetation into sound bedrock is obtained, (3) ascertain that all drill holes are thoroughly cleaned and dewatered prior to placement of any foundation concrete, (4) check all drill holes to assure that they are plumb and of the proper dia- lmeter, and (5) insure proper placement of concrete and 1 reinforcment. A feasible foundation alternate for lightly loaded buildings and machines which can tolerate one-half ( 1/2) (9) 871088 inch of differential settlement would be to support these structures and machines by conventional continuous and/or spread footings. These footings should bear on undisturbed natural soil and all exterior footings should be placed a minimum depth of thirty (30) inches below grade for frost protection. Foundations placed as recommended on the previous page may be designed for a maximum allowable soil bearing pressure of one thousand five hundred (1,500) pounds per square foot (dead load plus maximum live load. ) We recommend that foundations be designed for a minimum dead load pressure of five hundred (500) pounds per square foot to counteract the swelling pressure which wil develop if the subsoils become wetted. Foundation excavations should not remain open for a period of time prior to concrete placement so that the subgrade is allowed to dry. We anticipate that total settlement under the above- recommended maximum bearing pressure, as determined by laboratory consolidation tests, should be less than one ( 1) inch, generally considered to be within an acceptable tolerance for these types of structures. Basements, Dewaterinq & Slabs on Grade It is our opinion that basement construction is feasible on this site providing the finished basement slabs are placed a minimum of three (3) feet above the bedrock stratum or if complete dewatering systems are installed. No free groundwater was encountered at the time of our investigation, however, a I 10) 81088 potential perched water table problem does exist on this site. Therefore, it is recommended that all lower levels which are constructed within three (3) feet of the bedrock stratum be provided with complete dewatering systems. Providing a dewatering system is installed, the system should consist of four (4) inch diameter perforated pipe, under- slab gravel, a sump and pump or other suitable drain outlet. The perforated pipe should be placed around the entire perimeter ! of the lower basement area. These drains must be placed at least one (1•) foot below the finished lower level slab and should have a minimum grade of one-eighth (1/8) inch per foot. All lower level slabs surrounded by perimeter drains should be under- lain by a minimum of eight (8) inches of clean, graded gravel. or crushed rock devoid of fines. Two (2) inches of three-quarter (3/4) inch crushed rock should extend below the pipe. This gravel should extend at least two (2) feet above the bedrock stratum along the walls. It is recommended that building paper or straw be placed over the gravel to prevent clogging of the gravel media. Clay backfill should be used over the building paper to prevent surface water from entering the system. The drains should flow to a sump or by gravity to a suitable dis- charge area. The sump, if used, should be at least three (3) feet below the finished floor system and should have at least 1 one ( 1) foot of gravel around and below the sump. A pump adequate to discharge flows should be installed in the sump. Because of swelling pressures exerted by the expansive bedrock encountered at the site, it is felt that the only posi- t (11) 871088 tive solution for slab on grade construction where slabs are placed within three (3) feet of the bedrock stratum is a struc- tural floor system with a void beneath it. However, the cost Iof this type of system may be prohibitive. Therefore, with certain precautions and the recognition that some risk is in- volved, it is felt that a floating floor slab may be a reasonable alternative. If the owner is willing to assume the risk of future slab movement and related structural damage where slabs are within three (3) feet of the bedrock stratum, the following recommen- { dations may reduce slab movement and its adverse effect. All 1) slabs on grade should be designed structurally independent of all bearing members. We further recommend that all non-bearing ' partitions placed on floor slabs be provided with a slip joint 1 T (either top or bottom) such that the pressure applied by heaving floor slabs will not damage the portion of the structure above. It is emphasized that if the subsoils are kept dry, movement of slabs on grade will be minimized. However, if moisture is permitted to reach the expansive bedrock below the slabs, heaving will occur. We recommend that heavily loaded slabs be underlain by six (6). inches of three-quarter (3/4) inch road base compacted to a minimum of ninety-five percent of Standard Proctor Density ASTM D 698-78. (See Appendix C. ) Lightly loaded floor slabs which are not surrounded by perimeter drains may be underlain by four ( (4) inches of clean, graded gravel or crushed rock devoid of fines. All machine pads should be isolated from floor slabs. (12) 871088 To minimize and control shrinkage cracks which develop in slabs on grade due to temperature changes, we suggest that control 1 - joints be placed every ten ( 10) to twenty (20) feet and that the total area contained within these joints be no greater than four hundred (400) square feet. Pavement It is our understanding that roads between buildings will be gravel surface and that concrete pads will exist at each building for truck loading. Samples of the upper soils were classified for the purpose of determining pavement design criteria. The soils tested for Atterberg limits had group indecies ranging from sixteen (16) to nineteen 1 (19) . An "R" value of 8.6 was determined for this soil. Based on this data and on predicted occasional truck loads of up to 78 kips we recommend the following pavement thicknesses: Gravel Roads Select Gravel Base Course . - 6" Select Gravel Subbase Course - 18" Total Thickness - 24" All topsoil and other unsuitable materials should be stripped and removed from the proposed road areas prior to placing any fill materials or base course. The subgrade should then be scarified to a depth of six (6) inches and recompacted at or near optimum moisture to a minimum of ninety percent (90%) of Standard Proctor Density as specified by ASTM D 698-78. (See Appendix C. ) We recommend that a soil sterilant be used beneath pavement to retard weed growth. Imported pit-run approved by (13) 871088 the geotechnical engineer may be used as subbase. The base course overlying the subbase should consist of a hard, durable, crushed rock or stone and filler and should have a minimum "R" value of 80. The composite base course material should be free 1 from vegetable matter and lumps or balls of clay, and should meet Colorado Department of Highway Class 6 specifications as follows: } Sieve Size % Passing 3/4" 100 #4 30-65 #8 25-55 #200 3-12 Liquid Limit 30 Maximum Plasticity Index . . 6 Maximum The base course, subbase and any fill required beneath pavement areas should be placed at or near optimum moisture and compacted to at least ninety-five percent (95%) of Standard Proctor Density ASTM D 698-78. The base course must be shaped to grade so that proper drainage of the area is obtained. Concrete Pads Non-Reinforced Concrete - 6" Concrete pavement should be placed directly on the subgrada that has been uniformly and properly prepared in accordance with the above-recommendations. All concrete used in the paving shall meet ASTM specifications, and all aggregate shall conform to ASTM C-33 specifications. The concrete should be designed with a minimum modulus of rupture of six hundred (600) pounds per square inch in twenty-eight (28) days. It is recommended that 1 " t (14) 8710R8 im laboratory mix designs be done to determine the proper proportions of aggregates, cement and water necessary to meet these require- 1 ' ments. It is essential that the concrete have a low water-cement ratio, an adequate cement factor and sufficient quantities of entrained air. Joints should be carefully designed and constructed to ensure good performance of the pavement. If paving is done during cold weather, acceptable cold weather 1 procedures should be utilized. The concrete pavement should be properly cured and protected. Concrete injured by frost should be removed and replaced. It is recommended that the pavement ' not be opened to traffic until a flexural strength of four hundred (400) pounds per square foot is obtained or a minimum of fourteen (14) days after the concrete has been placed. Septic System It is our understanding that a minimal number of people will be employed at this facility and that daily flow rates to septic systems would be minimal. Five (5) preliminary percolation tests were performed at this site. Percolation rates ranging from twenty-five (25) to one hundred and thirty (130) minutes per inch were recorded on this site. The percolation rates on four (4) of the five (5) areas tested were below sixty (60) minutes per inch. No groundwater was encountered at this site to the depths explored. Firm bedrock was encountered within eight (8) feet of the ground surface only at the northwest corner of the site. Based on preliminary percolation data, it is our opinion that the majority of this site is suitable for construct- ing standard septic systems. (15) 1 871088 I (( GENERAL RECOMMENDATIONS ly ( 1) Laboratory test results indicated that water soluble sulfates in the soil are negligble, and a Type I cement may be used in concrete exposed to subsoils. Slabs on grade subjected to de-icing chemicals should be composed of a more durable cement with low water-cement ratios and higher air contents. (2) Finished grade should be sloped away from the structures on all sides to give positive drainage. Ten percent (10%) for the first ten (10) feet away from the structures is the sug- gested slope. (3) Backfill around the outside perimeter .of the l structures should be mechanically compacted at optimum moisture tout least ninety percent (90%) of Standard Proctor Density ASTM D 698 78. (See Appendix C. ) Puddling should not be permitted as a method of compaction. (4) All plumbing and utility trenches underlying slabs and paved areas should be backfilled with an approved material compacted to at least ninety-five percent (95%) of Standard Proctor Density ASTM D 698-78. Puddling should not be permitted as a method of compaction. 1 (16) 871088 (5) Gutters and downspouts should be designed to carry roof runoff water well beyond the backfill area. (6) Underground sprinkling systems should be designed such that piping is placed a minimum of five (5) 1 feet outside the backfill of the structures, heads should be designed so that irrigation water is not sprayed onto the foundation walls. These recommendations should be taken into account in the landscape planning. (7) Footing or pier sizes should be proportioned to equalize the unit loads applied to the soil and thus minimize differential settlements. y 1 (8) It is recommended that all compaction require- ments specified herein be verified in the field with density tests performed under the super- vision of a geotechnical engineer. (9) It is recommended that a registered professional engineer design the substructures and that he take into account the findings and recommen- 1 dations of this report. GENERAL COMMENTS This report has been prepared to aid in the evaluation of the and to assist the architect and/or engineer property in the design of this project. In the event that any changes in the design of the structure or its location are planned, Al (17) w 87106161 Ir the conclusions and recommendations contained in this report will not be considered valid unless said changes are reviewed lb and conclusions of this report modified or approved in writing by Empire Laboratories, Inc. , the geotechnical engineer of record. Every effort was made to provide comprehensive site coverage through careful locations of the test borings, while keeping the site investigation economically feasible. Variations in soil and groundwater conditions between test borings may be encountered during construction. In order to permit correlation between the reported subsurface condi- tions and the actual conditions encountered during con- struction and to aid in carrying out the plans and .specifi- cations as. originally contemplated, it is recommended that Empire Laboratories, Inc. , be retained to perform continuous review during the excavation and foundation phases of the work. Empire Laboratories, Inc. assumes no responsibility for compliance with the recommendations included in this report unless they have been retained to perform adequate on-site construction review during the course of Iconstruction. rl (18). • 871088 1 1-• APPENDIX A. 1 I f 871088 01 . r 1,, , 1:‘tt ..........-N.,.... •••••. 1 1 ( m r.-- \.,, l I _.i . 1 i z c- -- \ �. °• 0`V i. \__, , \ \ ,.....

Suggested Specifications for Placement of Compacted Earth Fill ` and/or Backfills. GENERAL A soils engineer shall be on-site to provide continuous observation during filling and grading operations and shall be the owner's repre- sentative to inspect placement of all compacted fill and/or backfill on the project. The soils engineer shall approve all earth materials prior to their use, the methods of placing, and the degree of compaction obtained. MATERIALS Soils used for all compacted fill and backfill shall be approved by the soils engineer prior to their use. The upper two (2) feet of compacted earth backfill placed adjacent to exterior foundation walls shall be an impervious, nonexpansive material . No material , including rock, having a maximum dimension .greater than six inches shall be placed in any fill . Any fill containing rock should be carefully mixed to avoid nesting and creation of voids. In no case shall frozen material be used as a fill and/or backfill material . J PREPARATION OF SUBGRADE All topsoil, vegetation (including trees and brush), timber, debris, rubbish, and other unsuitable material shall be removed to a depth • satisfactory to the soils engineer and disposed of by suitable means before beginning preparation of the subgrade. The subgrade surface of the area to be filled shall be scarified a minimum depth of six inches, moistened as necessary, and compacted in a manner specified below for } the subsequent layers of fill . Fill shall not be placed on frozen or muddy ground. 871088 C-2 PLACING FILL No•sod, brush, frozen or thawing material , or other unsuitable material shall be placed in the fill , and no fill shall be placed during unfavorable weather conditions. All clods shall be broken into small pieces, and distribution of material in the fill shall be such as to preclude the formation of lenses of material differing from the surrounding material . The materials shall be delivered to and spread on the fill surface in a manner which will result in a uniformly compacted fill . Each layer shall be thoroughly blade mixed during spreading to insure uniformity of material and moisture in each layer. Prior to compacting, each layer shall have a maximum thickness of eight inches, and its upper surface shall be approximately horizontal .. Each successive6" to 8" lift of fill being placed on slopes or hillsides should be benched into the existing slopes, providing good bond between the fill and existing ground. MOISTURE CONTROL While being compacted, the fill material in each layer shall as nearly as practical contain the amount of moisture required for optimum compaction , or as specified, and the moisture shall be uniformthroughout the fill. The contractor may be required to add necessary moisture to the fill } material and to uniformly mix the water with the fill material if, in the opinion of the soils engineer, it is not possible to obtain uniform moisture content by adding water on the fill surface. If, in the opinion of the soils engineer, the material proposed for use in the compacted fill is too wet to permit adequate compaction, it shall be dried in an acceptable manner prior to placement and compaction. COMPACTION When an acceptable, uniform moisture content is obtained, each layer shall be compacted by a method acceptable to the soils engineer and as specified in the foregoing report as determined by applicable standards. Compaction shall be performed by rolling with approved tamping rollers, 871088 C-3 pneumatic-tired rollers, three-wheel power rollers, vibratory compactors, or other approved equipment well-suited to the soil being compacted. If a sheepfoot roller is used, it shall be provided with cleaner bars attached in a manner which will prevent the accumulation of.material between the tamper feet. The rollers should be designed so that effective weight can be increased. MOISTURE-DENSITY DETERMINATION Samples of representative fill materials to be placed shall be furnished by the contractor to the soils engineer for determination of maximum density and optimum moisture or percent of Relative Density for these materials.. Tests for this determination will be made using methods conforming to requirements of ASTM D 698, ASTM D 1557, or ASTM D 2049. Copies of the results of these tests will be furnished to the owner, the project engineer, and the contractor. These test results shall be the basis of control for all compaction effort. DENSITY TESTS The density and moisture content of each layer of compacted fill will be determined by the soils engineer in accordance with ASTM D 1556, ASTM D 2167, or ASTM D 2922. Any material found not to comply with the minimum specified density shall be recompacted until the required density is. obtained. Sufficient density tests shall be made and submitted to support the soils engineer's recommendations. The results of density tests will also be furnished to the owner, the project engineer, and the contractor by the soils engineer. l 871088 7 C-4 rS • •• D-1 l f } I { .1 871088 I e •a t o ` `` ' — . i 02s 11N(1o9 4'IAM C 1 1 6II S / , i ) / ` / // I i ref,J `/ �� 4� at p/ / / 1 I �° 11 ) I 0 .M_17 1�1 % // j I J 1 \ `•rod 1 / if I / , / / / , 1 1 r�� r ' / ' ° I I \ 1 \ 1 I / 1 - c / I f 1 I Ilo / i I ti i j 1 Ili \ 1� i / l 114' I n; I r/ 411/07 (273A1-j �J • 1.1t/07 47( 071/a7Hl-S:9 I �I� /) � ' � w va7 ,tunes I - 1 / / 1 3N& 7OSSv1 19 J 1 l / I won /NV NN" . a b I ! / l„, I \ WV07 A 971 LI I I I / •.' / /1 • V Z 1 / ' /� I� / • / III I t) ( i .
