E10-11Q3 -·----~---·. ;., GEOTECHNICAL INVESTIGATION EASTERN HILLS STORM BASINS FORT WORTH, TEXAS 1.0 PROJECT REQUIREMENTS i; Grading plan sheets were provided for the entire project. The project includes a shallow ' 1 ' sedimentation basin (shown on sheet 101 ). The sedimentation basin will hold water for up to 48 hours and is separate from the main basin where the berm is to be built. The main basin will hold water for a few hours at a time during large infrequent storms (such as the 10 year or greater storm). It is understood that the smaller basin will not be full for longer . ' . ' 'i , .. . t , I .· t 1 , • • !; .. i 1 ' } ~ ! I I . I. '· ·I i than 2 to 3 hours and certainly not more than six hours during normal storms . The basin will be full for longer periods during exceptionally large storms of extended duration (longer than 24 hours). Excavation for the shallow sedimentation basin will require excavation depths of about 5 feet. Excavation for the main basin will require excavation depths up to 20 feet and fill depths up to 10 feet. The sides of the basins will be sloped along proposed side slopes ranging from 3: 1 to 4: 1. 2.0 SCOPE OF INVESTIGATION This report was prepared in accordance with our Proposal No . P09-0801 E-R1, dated August 20, 2009. The purposes of the study were to: 1) explore the subsurface conditions at the sites , 2) characterize the subsurface conditions by testing the physical and engineering properties of the underlying soil and rock strata and by observing groundwater conditions, 3) provide recommendations for the proposed improvements, and 4) provide comments related to temporary open cut trench excavations at the site . 3.0 FIELD OPERATIONS Four (4) deep geotechnical borings were drilled at approximate locations shown on the Boring Location Diagram on Figure 1. The boring locations were surveyed by Jacobs Engineering . The results of the boring program are presented on the Logs of Borings on Figures 2 thru 5. A key to the descriptive terms and symbols used on the logs is shown on Figure 6. .. --"" --.. MAS-TEK ENGINEERING & ASSOCIATES E10-1103 PAGE 1 i : .' ', ,, i : j i I ; I "' ? I ' i / ' I ,, ;,. [' An all terrain 4-wheeled drive drilling rig was used to advance these borings and to obtain samples for laboratory evaluation. Undisturbed specimens of the cohesive soils were obtained using standard, thin-walled , seamless tube samplers. These specimens were extruded in the field, logged, sealed, and packaged in plastic sample bags to protect them from disturbance and maintain their in-situ moisture content during transportation to our laboratory. The granular soils were sampled using split barrel samplers in connection with Standard Penetration Testing. The rock hardness and bearing capacity characteristics of the rock strata were evaluated by the Texas Department of Transportation Cone Penetration Test. This test consists of measuring the penetration of a 3-inch diameter cone driven with a 170-pound hammer falling 24 inches . The results of these tests are reported on the boring logs. 4.0 LABORATORY TESTING r i Samples were examined at our laboratory by the project geotechnical engineer. Selected samples were subjected to laboratory tests under the supervision of this engineer. : -1 i' The in-situ unit weight, moisture content, liquid and plastic limits, and grain size characteristics of selected soil samples were tested. These tests were used to estimate the shear strength of the different soil strata and as an indication of the uniformity of the material. Hand penetrometer tests were also performed to provide an indication of the variation of soil strength with depth. Unconfined compression tests were performed on representative samples of the clay overburden soils. These results are presented on the Logs of Borings. The results of sieve analyses are shown on Figures 7 and 8. In order to evaluate the shear strength characteristics of the site soils, direct shear tests and C-U triaxial tests with pore pressure measurements were performed . These results are shown on Figures 9 thru 12. The results of sulfates determinations are reported on Figure· 16. 5.0 SURFACE CONDITIONS 5.1 SITE GEOLOGY As shown on the Tarrant County sheet of the Geologic Atlas of Texas, the site is located on or near the contact of the Grayson Marl/Main Street Limestone Formation and the Woodbine Formation and is very close to the contact of the Pawpaw Formation . Hard Limestone and sandstone can be present at shallow depths within these formations. Hard rock outcrops MAS-TEK ENGINEERIN<f& Ass6'c1ArEs -" "' E10-1103 PAGE2 ' i ' I ' l; I. '·. are also possible as well as large hard sandstone boulders . Existing fill was observed in some areas of the site. The fill may contain large concrete and rock boulders in some areas. Hard rock was encountered at depths as shallow as 7 feet in the actual borings but could be present at shallower depths in some areas . 5.2 SUBSURFACE CONDITIONS Subsurface conditions encountered in the borings , including descriptions of the various strata and their depths and thicknesses, are presented on the Logs of Boring . Note that depth on all borings refers to the depth from the existing grade or ground surface present at the time of the investigation. Boundaries between the various soil types are approximate. As shown on the Tarrant County sheet of the Geologic Atlas of Texas, the site is located on or near the contact of the Grayson Marl/Main Street Limestone Formation and the Woodbine Formation and is very close to the contact of the Pawpaw Formation . Hard Limestone and sandstone can be present at shallow depths within these formations. Hard rock outcrops are also possible as well as large hard sandstone boulders . Existing fill was observed in some areas of the site . The fill may contain large concrete and rock boulders in some areas. Hard rock was encountered at depths as shallow as 7 feet in the actual borings but could be present at shallower depths in some areas. Shallow rock outcrops and existing fill were observed around the site . As indicated on the boring logs, existing fill soils were encountered at Borings 82, 83 and 84 to depths of up to 10 feet. At Borings 82 and 83 , the deeper existing fill consists of water-bearing fill materials containing varying amounts of sand, gravel and broken asphalt. 5.3 GROUNDWATER The borings were advanced with continuous flight auger drilling equipment. This method : 1 allows relatively accurate groundwater observations to be made while drilling . Groundwater seepage was observed in the borings at depths ranging from about 6 to 1 O' below the existing ground surface at the time of this investigation. This groundwater is perched within the existing fill and is present within the underlying granular soils overlying the shale i, i formation. Groundwater is also present within the jointed marly clay and fractured rock . The subsurface water conditions are subject to change with variations in climatic conditions and are also functions of subsurface soil conditions and rainfall. It should be anticipated that ----~ -._. ---..... _-. MAS-TEK ENGINEERING & ASSOCIATES E10-1103 PAGE 3 groundwater seepage will be encountered at shallower depths in all areas after periods of rain. 6.0 RECOMMENDATIONS Due to the presence of water bearing fill soils and fine to coarse sand strata at this site, the basin side slopes would be subject to slope failures caused by erosion when basins are full followed by rapid drawdown of water levels within the basins as they drain. Note: It is recommended that both basins be lined with on-site clay or marly clay soils having a Pl of at least 35. The clay should be relatively free of sand, gravel, rock fragments and broken asphalt. The on-site clay used to line the basins should have no more than 15% retained on the No . 200 sieve . The basin side slopes should also be flattened to 4(H):1(V) or flatter due to soil conditions at this site. We recommend the following. 1. Excavate all existing fill. Remove and haul off all large rock, broken asphalt, concrete , etc. having a rock size larger than 4 inches . Stockpile remaining fill for future re-use. 2.,. Excavate to final depth. Where granular soil or fractured tan weathered limestone is exposed along the bottom or interior side slopes, as verified by a Mas-Tek Engineer, over-excavate to allow placement of a 3 foot thick on site clay liner along the interior side slopes and a 2 foot thick clay liner along the bottom. Where jointed clay or marly clay is exposed within the basin interior, over-excavation is not required . For these soils, scarify to a depth of 12 inches, as verified by a Mas-Tek Engineer, and compact at optimum to +4% above optimum to 95% ASTM 0698 . . 3. Fill in 8 inch horizontal benched lifts as verified by MTE and compact at -2% to +2% of optimum to 95% ASTM 069.8. General embankment fill should consist of well blended clay soils that may contain sand, gravel, broken rock and broken asphalt having a maximum size of 4 inches. The general embankment fill should be well blended and should contain at least 40% passing the No. 200 sieve. MAS-TEK ENGINEERING & ASSOCJ~TES -!E10-1103 PAGE4 ,, ' ! ' '' .J ' ii' I' ,, r i' Note: On-site clay used for the clay liner should have at Pl of at least 35 with no more than 15% retained on the No . 200 sieve . 4. Fill placed along the side slopes should be placed beyond final lines and grades and compacted in horizontal benched lifts to 95% ASTM D698 at -2% to +2% of optimum. Final grading should consist of trimming off loose non -compact fill from the slopes . Compaction of loose fill soil along the side slopes should not be allowed. 5. Due to the high plasticity clay soils in some areas of this site, and non-plastic granular soils in other areas, side slopes should be no steeper than 4(H):1 (V) slopes to minimize future skin slides. Shallow skin slides can still occur along 4(H):1 (V) slopes. Shallow skin slides are not considered to be major slides but are maintenance considerations that must be repaire.d immediately be 1ore larger slides occur. The FOS against a deep sl ide is over 1.5 if 4:1 slopes are used , a clay line is used and the existing fill is reworked per this report . See Appendix A. 7.0 EMBANKMENT SLOPES The proposed embankments should be flattened to 4(H): 1 (V) or flatter o minimize skin slides caused by desiccation cracks during dry weather followed by heavy rains during the I' , following rainy season . Skin slides along slopes can be reduced by irri ation during dry ; : 'l 1 • I·' i t .~ ! weather to minimize desiccation cracks in the underlying soil embankm nt. Sk in slides within unprotected 4(H):1 (V) slopes occur much less frequently and req \ ire much fewer repairs than unprotected 3(H):1(V) slopes . 8.0 UTILITY EXCAVATIONS 8.1 TRENCH EXCAVATIONS It is understood that open cut trench excavations will be performed at t is site and that trench depths will typically be on the order of 10 to 15 feet below the existing ground surface . i.'

'i · As indicated on the Boring Logs, soil and rock conditions will vary considerably at the invert depths. Subsurface conditions will range from water bearing granular soils, hard to very hard fractured limestone, very stiff to hard jointed clay1 jointed marly claY, and fill soil containing water bearing granular layers. The clay soils are jointed and fissured. !i · For trench excavations to any depth at this site, it will be necessary to employ either sloped excavations or temporary bracing due to unstable soil or unstable rock (sand, gravel, fill soil, jointed marly clay, weathered limestone), I I For trench excavations to any depth at this site, it will be necessary to employ either sloped excavations or temporary bracing, regardless of the soil conditions encountered . General guidelines for the design of these two alternatives are discussed in the following sections. 8.2 OPEN CUTS Recommended slope ratios for the respective soil conditions are presented graphically on Figure 13. Trench excavations to any depth at this site in l!._nstabl~--~oil 9o_r,dit_ion~ should be cut back as described above. It should be recognized that free standing slopes will be less stable when influenced by groundwater or saturated by rain. Surcharge loads, such as those resulting from excavation spoil, or equipment, should be placed no closer than two feet from the crest of the slope, or in accordance with OSHA regulations. Vehicle traffic should be maintained at least five feet from the edge of the crest. Excavations will encounter fill soils placed during previous construction activities and groundwater seepage. Where encountered, these soils should be sheeted, shored, and braced, or laid back on slopes no steeper than 1.5 (H): 1 (V). The contractor will need to take measures to avoid undermining and damaging the existing underground utilities and any adjacent pavements or structures. -~ ... 8.3 TRENCH BRACING / BORE PIT SHORING Where site limitations require excavations to have vertical side walls, an internal bracing system will be necessary. Bracing may consist of timber or steel shoring or manufactured steel trench braces. The lateral pressure distribution to be used in the design of trench .----~-~--·-. ---·-.. ---..~- MAS-TEK ENGINEERING & ASSOCIATES , E10-1103 PAG.E 6 I: r bracing may be determined as presented on Figures 14 and 15. It should be recognized that pressures are not included from hydrostatic pressures, surcharge loads, or traffic live loads at trench side walls, dynamic loads, and vibration, which if present, must be included in bracing design. In lieu of a shoring system, a trench shield consisting of a prefabricated rigid steel unit adequate to withstand anticipated lateral pressures may be used. 8.4 DEWATERING Groundwater was encountered in the test borings during drilling as ind icated on the boring I / J. : 'j : , logs . Groundwater will be encountered at relatively shallow depths in some areas, ! 1·. particularly after periods of heavy rain . See Section 5.3 . In areas where groundwater is ; i I • ,'1,, I encountered , a system of well points, ditches, sumps, and pumping will be required to provide groundwater control. The design of the actual dewatering system required is the contractor's responsibility. This includes the control of tail-water flow through previous backfilled sections . 8.5 CONSTRUCTION CONSIDERATIONS ! l I , " The following guidelines are presented to aid in the development of the excavation plans : 1 ' : I: Surface areas behind the crest of the excavations should be graded so that surface water 1 r does not pond within 15 feet of the crest, nor drain into the excavation . 1 • Heavy material stockpiles should not be placed near the crest of slopes per OSHA requirements . Similarly, heavy construction equipment should not pass over or be parked within 5 feet of the cre$t. The crest of slopes should be continually monitored for evidence of movement or potential problems. Freestanding slopes will become less stable when influenced by groundwater or· saturation by rain . 8.6 TRENCH BACKFILL The excavated soils can be used for trench backfill. Use of rock fragments greater than six (6) inches in any dimension should be prohibited, since attaining uniform moisture and ·:~.:-... ~.--··-.-.,.;;.,.--.~-----· -·-·"""···.,...,v~.=...

'"' ' 1 ,l 'I density without voids would be difficult. The backfill should be placed in thin compacted lifts as specified below. The fill materials should be free of surficial vegetation or debris. Clay and silty clay fill soils having a Pl greater than 25 should be placed in 8 inch horizontal loose lifts and compacted to at least 95 percent of the maximum dry density as determined by ASTM D-698 test method . The clay and sandy clay should be compacted at optimum to +4% above the optimum moisture content. Silty clay and calcareous clay fill soils having a Pl of less than 25 should be placed in 8 inch horizontal loose lifts and compacted to at least 95 percent of the maximum dry density as determined by ASTM D-698 test method. These lower Pl soils should be compacted at -2% to +2% of optimum moisture. The on-site limestone may be used as utility trench backfill. Broken limestone should be adequately crushed to where individual rock fragments have a diameter of less than 6 inches. The crushed limestone should be placed in 8 inch horizontal loose lifts and compacted to at least a minimum of 95 percent of the maximum dry density as determined by ASTM D-698 test method at -2% to +2% of optimum moisture . The limestone materials should be crushed using a compactor of sufficient size and weight to crush the rock . Note: For fill depths below 15 feet and 25 feet depths respectively , the compaction level should be increased to 98% and 100% ASTM D698, respectively, where it is desired to reduce post-construction settlements. 8.7 CORROSION CONSIDERATIONS Based on the results of sulfates testing, sulfates levels of the on-site soils are very high and exceed 40,000 ppm . Appropriate measures should be taken during design of the concrete mix design for burled concrete per ACI. The clay and marly clay soils are also considered to be highly corrosive to buried metals . ... MAS-TEK ENGINEERING & ASSOCIATES E10-1103 PAGE 8 '' i r. .. I. \. f r 9.0 INSPECTION AND TESTING Many problems can be avoided or solved in the field if proper inspection and testing services are provided . It is recommended that all excavation and fill placement be monitored by Mas-Tek Engineering . This includes placement and compaction of trench backfill. Inspection should be performed prior to and during concrete placement qperations. 10.0 LIMITATIONS The professional services · which have been performed, the findings obtained, and the recommendations prepared were accomplished in accordance with currently accepted geotechnical engineering principles and practices . The possibility always exists that the subsurface conditions at the site may vary somewhat from those encountered in the boreholes. The number and spacing of test borings were chosen in such a manner as to decrease the possibility of undiscovered abnormalities, while considering the nature of loading, size, and cost of the project. If there are any unusual conditions differing significantly from those described herein, Mas-Tek Engineering should be notified to review the effects on the performance of the recommended foundation system. The recommendations given in this report were prepared exclusively for the use of the Client and their consultants. The information supplied herein is applicable only for the design of the previously described development to be constructed at locations indicated at this site and should not be used for any other structures, locations, or for any other purpose .

It is the intent of the City of Fort Worth to comply with the requirements of the Asbestos National Emissions Standards for Hazardous Air Pollutants (NESHAP) found at 40 CFR Part 61, Subpart M. This specification will establish procedures to be used by all Excavators in the removal and disposal of asbestos cement pipe (ACP) in compliance with 02/09/2010 SC-52 PART D -SPECIAL CONDITIONS NESHAP . Nothing in this specification shall be construed to void any provision of a contract or other law, ordinance, regulation or policy whose requirements are more stringent. B. ACP is defined under NESHAP as a Category II , non-friable material in its intact state but which may become friable upon removal, demolition and/or disposal. Consequently, if the removal/ disposal process renders the ACP friable, it is regulated under the disposal requirements of 40 CFR 61 .150. A NESHAP notification must be filed with the Texas Department of Health . The notification must be filed at least ten days prior to removal of the material. If it remains in its non -friable state, as defined by the NESHAP, it can be disposed as a conventional construction waste. The Environmental Protection Agency (EPA) defines friable as material, when dry, which may be crumbled , pulverized or reduced to powder by hand pressures . C. The Generator of the hazardous material is responsible for the identification and proper handling, transportation, and disposal of the material. Therefore , it is the policy of the City of Fort Worth that the Excavator is the Generator regardless of whether the pipe is friable or not. D. It is the intent of the City of Fort Worth that all ACP shall be removed in such careful and prudent manner that it remains intact and does not become friable . The Excavator is responsible to employ those means , methods, techniques and sequences to ensure this result. E. Compliance with all aspects of wo rker safety and h~alth regulations including but not limited to the OSHA Asbestos Standard is the responsibility of the Excavator. The City of Fort Worth assumes no responsibility for compliance programs , which are the responsibility of the Excavator. (Copy of forms attached} F. The removal and disposal of ACP shall be subsidiary to the cost of installing the new pipe unless otherwise stated or indicated on the project plans or contract documents . D-67 STORM WATER POLLUTION PREVENTION (FOR DISTURBED AREAS GREATER THAN 1 ACRE) PERMIT: As defined by Texas Commission on Environmental Quality (TCEQ) regulations, a Texas Pollutant Discharge Elimination System (TPDES) General Construction Permit is required for all construction activities that result i n the disturbance of one to five acres (Small Construction Activity) or five or more acres of total land (Large Construction Act ivity). The contractor is defined as an "operator" by state regulations and is required to obtain a permit. Information concerning the permit can be obtained through the Internet at http://www.tnrcc.state.tx .us/permitting/water perm/wwperm/construct.html. Soil stabilization and structural practices have been selected and designed in accordnncc with North Ccntml Texas Council of Governments Best Management Practices and Erosion Control Manual for Construction Activities (BMP Manual). This manual can be obtained through the Internet at www.dfwstormwater.com/runoff.html. Not all of the structural controls discussed in the BMP Manual will necessarily apply to this project. Best Management Practices are construction management techniques that, if properly utilized , can minimize the need for physical controls and possible reduce costs. The methods of control shall result in minimum sediment retention of not less than 70%. 02/09/2010 SC-53 PART D -SPECIAL CONDITIONS NOTICE OF INTENT (NOi): If the project will result in a total land disturbance equal to or greater than 5 acres , the contractor shall sign at the pre-construction meeting a TCEQ Notice of Intent (NOi) form prepared by the engineer.

Any alterations to the SWPPP proposed by the contractor must be prepared and 02/09/20 10 SC-54 PART D -SPECIAL CONDITIONS submitted by the contractor to the engineer for review and approval. A Notice of Termination (NOT) form shall be submitted within 30 days after final stabilization has been achieved on all portions of the site that is the responsibility of the permittee, or, when another permitted operator assumes control over all areas of the site that have not been finally stabilized. SMALL CONSTRUCTION ACTIVITY -DISTURBED AREA EQUAL TO OR GREATER THAN ONE ACRE BUT LESS THAN FIVE ACRES: Submission of a NOi form is not required . However, a TCEQ Site Notice form must be completed and posted at the site . A copy of the completed Site Notice must be sent to the City of Fort Worth Department of Environmental Management at the address listed above. A SWPPP, prepared as described above, shall be implemented at least 48 hours before the commencement of construction activities . The SWPPP must include descriptions of control measures necessary to prevent and control soil erosion, sedimentation and water pollution and will be included in the contract documents.

PART 3 -EXECUTION 3.01 SITE PREPARATION : In general , "site preparation ," as specified in Section 02200, shall be performed in advance of grading and earthwork operations and shall be completed over the entire area of earthwork operations . EARTHWORK 02300 -2 - 3.02 TOPSOIL A. The removal and storage of topsoil shall occur after site preparation is complete and before excavation and embankment construction begin . Likewise, topsoil will be replaced after excavation and embankment construction are complete. B . Removal : Topsoil shall be stripped to an average depth of six inches (6") from areas where excavation and embankment construction are planned . Topsoil may be obtained from greater depths if it is uncontaminated by the substratum and it is of good quality, in the opinion of the ArchitecUEngineer. C. Storage: Topsoil shall be stored in stockpiles conven iently located to areas that will later receive the topsoil. Stockpiles shall be out of the way of earthwork operations in locations approved by the Owner or ArchitecUEngineer. Stored topsoil shall be kept separate from other excavated materials and shall be protected from contamination by objectionable materials that would render it unsuitable. D . Timing: Topsoil will not be replaced (deposited) until construction activities are complete that would create undesirable conditions in the topsoil , such as overcompaction or contamination. Trenching for items such as electrical conduit and irrigation pressure lines must be complete before topsoil replacement may begin . D . Replacement: Topsoil will be deposited in a single layer or lift . It will be placed, processed, compacted, and graded to leave a finished layer of topsoil not less than five inches in depth. Unless otherwise indicated , topsoil will be replaced over all areas of earthwork (including slopes), except where pavement is planned. F. Grading: Topsoil will be final graded to the elevations shown on the plans . Fine grading will be accomplished with a weighted spike harrow, weighted drag, tractor box blade, light maintainer, or other acceptable machinery. All particles of the finish grade shall be reduced to less than one inch in diameter or they shall be removed . All rocks of one inch or greater shall also be removed . Grading operations and equipment will be such that topsoil does not become overcompacted . Bulldozer blades and front-end loader buckets are not acceptable devices for topsoil grading operations. Final grading within five feet of constructed or installed elements shall be hand raked . G . Acceptability: Finished areas of topsoil are satisfactory if they are true to grade, true in plane, even in gradient (slope), uniform in surface texture , and of normal compaction. Areas of loose granular pockets or of overcompacted soils are not acceptable and will be reworked. Finished areas will promote surface drainage and will be ready for turfgrass planting. 3.03 UNCLASSIFIED EXCAVATION A. All excavated areas shall be maintained in a condition to assure proper drainage at all times, and ditches and sumps shall be constructed and maintained to avoid damage to the areas under construction. B. Surplus Material: 1.

Excavation in Rock: The use of explosives will not be permitted . Unless otherwise indicated on the plans , excavation i n solid rock shall extend six inches (6 ") below requ ired subgrade elevation for the entire width of the area under construction and shall be backfilled with suitable materials as indicated on the plans. 3 .04 EARTH EMBANKMENT A. Earth embankment is defined as embankment composed of suitable materials removed in unclassified excavation and/or i mported fill. The construction of embankment includes preparing the area on ~hich fill is to be placed and the depositing, condit ioning, and compaction of fill material. B. General : Except as otherwise required by the plans , all embankment shall be constructed in layers approximately parallel to the finished grade of the graded area , and each layer shall be so constructed as to provide a uniform slope as shown on the grading plan. Embankments shall be constructed to correspond to the general shape of the typical sections shown on the plans, and each section of the embankment shall correspond to the detailed section or slopes established by the drawings. After completion of the graded area , embankment shall be continuously maintained to its finished section and grade until the project is accepted . C . Preparation : Prior to placing any embankment, all preparatory operations will have been comp leted on the excavation sources and areas over which the embankment is to be placed . The subgrade shall be proof rolled to detect soft spots, which if exist, should be reworked . Proof rolling shall be performed using a heavy pneumatc tired roller, loaded dump truck , o r simi lar piece of equipment weighing approximately twenty five (25) tons except as otherwise specified for tree protection and areas inaccessible to vehicular compactors . Stump holes or other small excavations in the limits of the embankments shall be backfilled with suitable material and thoroughly tamped by approved methods before commencing embankment construction . The surface of the ground, including plowed , loosened ground, or surfaces roughened by small washes or otherwise, shall be restored to approximately its original slope by blading or other methods , and, where ind icated on the plans or required by the Owner, the ground surface , thus prepared , shall be compacted by sprinkling and rolling. D . Scarification : The surface of all areas and slopes over which fill is to be placed, other than rock , shall be scarified to a depth of approximately six (6 ") inches to provide a bond between the exist ing surface and the proposed embankment. Scarification shall be accomplished by plowing , d iscing , or other approved means. Prior to fill placement, the loosened material shall be adjusted to the proper moisture content and recompacted to the density specified herein for fill. E. Benching: Scarification is normally adequate for slop ing surfaces. However, in certain cases where fill is to be placed against hillsides or existing embankment with slopes greater than 4 : 1, the Owner may direct the Contractor to key the fill material to the existing slopes by benching. A minimum of two feet (2') normal to the slope shall be EARTHWORK 02300 -4 - removed and recompacted to insure that the new work is constructed on a firm foundation free of loose or disturbed material. F. Depositing : Fill material shall be placed in horizontal layers or lifts , evenly spread, not to exceed eight (8 ") inches in loose depth before conditioning and compaction. Unless otherwise permitted, each layer of fill material shall cover the length and width of the area to be filled and shall be conditioned and compacted before the next higher layer of fill is placed. Adequate drainage shall be maintained at all times . G. Watering : At the time of compaction , the moisture content of fill material shall be such that the specified compaction will be obtained , and the fill will be firm , hard, and unyielding . Fill material which contains excessive moisture shall not be compacted until it is dry enough to obtain the specified compaction. H. Compacting: Each layer of earth fill shall be compacted by approved tamping or sheepsfoot rollers, pneumatic tire rollers, or other mechanical ineans acceptable to the Owner. Hand-directed compaction equipment shall be used in areas inaccessible to vehicular compactors. I. Grading: Embankments shall be constructed in proper sequence and at proper densities for their respective functions. All embankment serves in one capacity or another as subgrade (e.g., under topsoil , under concrete and asphalt pavement, under structures, etc.). Accordingly, the upper layer of embankment shall be graded to within plus or minus 0 .10 foot of proper subgrade elevation prior to depositing topsoil, and prior to the construction of pavements, slabs, etc. 3.05 DENSITY CONTROL A. Earth Embankment in General : Earth embankment shall be compacted in lifts at a minimum of ninety-five percent (95%) of Standard Density ASTM D698 with plus or minus two percent (2%) percentage points of optimum moisture content. B. Earth Embankment Under Structures and Pavement: The top six (6 ") inches of natural earth comprising the subgrade for structural slabs or for areas of pavement shall be ninety five percent (95%) of Standard Density ASTM D698 with the moisture content at four percent (4%) above optimum moisture content. 3.06 MOISTURE MAINTENANCE: The specified moisture content shall be maintained in all embankments that are to function as subgrade for structures , areas of pavement, or for select embankn:ient. After completion of the embankment , the Contractor shall prevent excessive loss of moisture in the embankment by sprinkling as required . Loss of moisture in excess of two percent (2%) below optimum in the top twelve inches (12 ") of the fill will require that the top twelve inches (12 ") of the embankment be scarified, wetted, and recompacted prior to placement of the structure, select fill or pavement. If desired, the Contractor may place an asphalt membrane of emulsified or cutback asphalt over the completed embankment and thus eliminate the sprinkling requirement. 3.08 TOPSOIL REPLACEMENT: Topsoil shall be carefully placed to avoid any displacement or damage to the subgrade. If any of the subgrade is rutted, damaged or displaced it shall be restored prior to placing topsoil. Topsoil shall be replaced as specified herein per Item 3.02 .
