We evaluated fill placxment a�tivities within the Pod 3 area <br /> whcrc Building Nos. 16 througfi 18 are located o0 7 occas�ons betw�n Aagust 8 and 18, 2005 (refer to <br /> Fidd Rcpcxt Nos.38 through 44). <br /> Wc cvaluated t6c fll soil by perfmming laboratory tesling ihat gtnually consisted of maximum dry <br /> density (MDD) cvalustions Per Amcrican S��aY �r Tcsting and Matcrisls (ASTM) D1557 tcsting <br /> procodure. T6e fill used within the building footprint atai, generally cm�sixted oC the an-site glxia] till <br /> and advencc ooLweah aoils. <br /> We evaluated the compection of fill by d�serving placeme�P�dures, bY P�r�o�ning io-plecc dcnsity <br /> tests and by Nmbing wi11� a frinch diameter proba rod. fill was ge�eially compacted to at least <br /> 95 perceM of tho MDD in areas bcncath Build'mg Nos. 16 and I8. <br /> Based on our olrservetions and evaluetioas, it is our opinion t6at the fill plecad wifhin the footprint of <br /> Building Nos. 16 through 18 during thc mess gading Pcriod wes compacted in gcncral accordancc with <br /> our iccommendations and the project plans end spxificatioas. <br /> SOIL B�J1RINf3 VERIFlCAT10N <br /> We evaluated the footing subgrade goils at Auilding Nos. 16 l►mwgh I8 mid vcrified soil bcaring on 7 <br /> �ccasions bctween Apri14,2006 and August 3,2006(rcfer to Pield Report Nos. 130, ]31, 134, 135, 14A, <br /> 147 and 148).
