AET #95-2169 - Page 3 Deviations from the above design information could necessitate altering our conclusions and recommendations. Contact us if the information stated is different from the actual design. Elevations and locations presented in this report were referenced to grade and off -set staking provided by the contractor. Previously, American Engineering Testing, Inc. (AET) conducted a subsurface exploration program at the referenced site. The results were included in our November 24, 1993 report (AET Job No. 93-2104). Refer to that report for pertinent background information. We observed the excavation for the building during the period from August 7 to 22, 1995. We were not present at the site on a full-time basis. Our observations consisted of periodic visits to the site, as requested by the contractor. In conjunction with observing the bottom of the excavation, we conducted shallow han(' auger borings acid hand cone penetrometer probes in the bottom of the excavation. The soils encountered were classified in general accordance with ASTM:D2488. The soils exposed in the bottom of the excavation for the building were judged to be natLrally deposited sand with silt (SP-SM) and silty sand (SM). Hand cone penetrometer probes conducted in the soils exposed in the bottom of the excavation appeared to indicate these soils have sufficient strength to support the fill and the 3,000 psf foundation loadings. The base of the excavation generally sloped from ab-,ut elevation 915 on the south end, down to about elevation 905 on the north end.
