Prepare a Summary report at the conclusion of cur construction monitoring services. Doeollod results of our construction monitoring services have been presented in our daily field repots for dw project, tattabon 1 through 32, dated May 9, 1997 through November A, 1997. Copies of the fluid reports hive treat provided to the site superintendent. OBSERVATIONS SUBSURFACE CONDITIONS R'e evaluated subsurface soil red ground water condidom by excavating eleven test pits throughout the site. 1n addition, we reviewed three test pit logs mnpleted by Cucade Geotsehnlcal EtSlacoring provided in their Jum 2, 19% report. Portions of Bulldinj A and BuUding R am were btenhetad with All up to 9 feet thick. Fill generally consisted of loose silly m d with vatylag aatounts of organic$. Bawth the All, a"= deals to very dents gleoittl till consisting of silty sand with varying amotms of gravel was encountered in all of the test pits. 9ubsurtwe conditions in the sea of buudiM C consisted, of deers native glacial till. GRADING Bolt cutliog and filling were required to aehleve the deep grades in fhe building areas. Structural All used to achieve the design grades In the building area generally consisted of 01141te material. In -play density tow were conducted ma the structural All was placed mod compacted. Paved uau were brought to grade using on -tile native glacial till and On -Ike silty sand with orgattics (previously placed fill). In general the AU contalag organics was of marginal quality and was placed in the lower elevations Of the light traffic areal Qmrking) northeast of BuUdlag B. This material was compacted to the extent possible. A geotmile fabric was placed over these areas and capped with 2 tense of structural fill corupaeted to 95 peraat. Fill placed in the heavy traffic seas was compacted to 93 percent. The on -site soils were generally above opt n m mobturs for eductive compactor. This required conoWerable meal tioe and, on ocuation, the addition of lute to reduce moisture eontatus enough to achieve adequsts compaction. Oar observations WA tau results Indicate that tba stnutu al fill was compacted in general scoordum with our recommendations. 0 8 0 B o a i e 1 0 r r IMk Me. 5e014011-77-1110 m 007
