However, suitability reinforced augercast piles will provide <br /> an additional capacity. The recommended allowable lateral capaciry of augercast piles (applied <br /> at the pile top); assumes a fixed head condition. <br /> The lateral capacities presented in Table 1 above �vere determined assuming 0.5 inch of <br /> deflection at the pile top With the pile tops fixed to prevent rotation. A factor of safery of 2 <br /> was applied to the allowable lateral capacities. <br /> 9.3 Pile Inspections <br /> The actualtotal length of each pile may be adjusted in [he field based on required capaciry and <br /> condi[ions encoun[ered during drilling. Since completion of the piles takes place below <br /> ground, the judgment and experience of the ceotechnical eneineer or 6is field representative <br /> must be used as a basis for determinine the required penetration and acceptability of each pile. <br /> Consequently, use of the presented pile capacities iu the desien requires that all piles be <br /> inspected by a qualified representative from our firm who can interpret and collect [he <br /> installation data and observe the contractor's operations. The geotechnical engineer, acting as <br /> the ownr.r's field representative, would determine die required lengths of the piles and keep <br /> records of pertinent installation data. .A final summary report would then be distributed, <br /> following completion of pile installation. <br /> ]0.0 LAT6RaL WALL PRESSURGS <br /> All backfill behind retaining walls should be placed as per the recommenda[ions for strucmral <br /> fill as described in Section 3.0 of this report, and as described below. Temporary and <br /> permanent horizontally backfilled �valls that are free to yield laterally at least 0.1 percent of <br /> their heieht may be designed using an equivalent fluid equal to 40 pounds per cubic foot (pc�. <br /> �u,�� �9, z000 EXH IBIT #� .aSSOGATED E.IRTX SC(ENCES, LNC. <br /> 1�'S�1a - RF�Jf9,l � LD-D'Jddlh- N']A FqGE�F I� Page ]0 <br />
