fF Dcvclopmcnt LP . July 21,200G Pagc 2 FILL MATERIAL EVALUATION APIO REQU�RED COMPACTION On-sitc soils �vcre used as fill and backfll at the site. We cvaluatcd fill placemcnt activities within the Pod 1 arca whcrc Building Nos. 3 and 4 arc located during thc mass grading period on 25 occasions bch+•cen Junc 23 and July 20,2005 (refcr to ficld report Nos. 1 thmugh 25). Wc cvalualed lhc fill coil by pcdom�in�; laborarory tcsting that genc�ally consistcd of ma�:imum drv dcnsily (MDD)cvaluations per ASTM D1557 testing proccdurc. Thc fill used within the (loor slab arca, gcncrally consislcd of d�c on silc glacial lill and advancc outwash soils. Wc cvoluatt� thc compaction of f 11 by obscrving plecemenl proccdures, by performing in-place density tests and by p�obing wilh a %n-inch diametcr probc rod. Fill was generally compacted to at Ieast 95 �x:rccnt o�thc �4:7D in arcas bcncath Duilding Nos.3 and 4 during thc mnss grnding period. Bascd on our obscrvations and cvaluations, it is our opinion that thc fill pinced within thc footprint of Building Nos. 3 and 4 during the mass grading period wcre compnctcd in general accordancc with our rccommcndations and lhc projcct plans and specifications. SOIL BEARING VERIFICATION Wc cvalualcd thc footing and slab subgradc soils at Building Nos. 3 and 4 and vcrificd soil bcaring on 8 a:casions bchrccn Aogust 4 and Septembcr 2G, 2005 (refer to ficld repor! Nos. 36, 39, 42, fi7 Ihrough 71). Loosc soil� whcn cncountcrcd at footing and slab subgradc clevation al Building Nos. 3 and 4 wcrc ovcr-cxcovatcd and repinccd with swctural fill compactcd to at Icast 95 perccnt of MDD. Bascd on our obscrvations, it is our opinion that soil bcaring pressurc of 2,500 psf was achicvcd in Ihc footing subgradc of Building Nos. 3 and 4 and thc slab subgradc was prcparcd .�gcncral accorclnncc with our rccommcndnlions and thc projcct plans and spccifications. MSE WALL CONSTRUCTION Wc obscrvcd construction of thc MSE�vall S7 along thc north and cast side of Building No. 4 and along portion of thc cast sidc of Auilding No. 3 on 5 occasions betwcen July 19 and July 28,2(HIS (rcfcr to ficld rcport Nos. 24, 25, 2R through 31). Wc also cvaluatcd thc compaction of fill within thc rcinforccd zonc bcl�ind thc MSE wall S7 by obscrving placcmcnt proccdures, by performing in-placc dcnsity tcsls and by probing wilh a '/:-inch diamctcr probc rod. f3ascd on our obscrvalions and cvalualions, il is our opinion that thc MSE wall S7 was consWcted in gcncrnl accordancc��•ilh onr rccommcndations and thc projcct plans and specifications. �% b i!e ACx Y.i0-004.03 GEOENGINEERS�
