One representative soil sample was returned to <br />our laboratory for analysis of the maximum dry density and optimum moisture content in <br />accordance with ASTM D1557-02 (Modified Proctor). Density test results indicate adequate <br />compaction of at least 95 percent at the tested locations of the building slab backfill. <br />Based on our observatians and testing, the earthwork construction was accomplished in <br />accordance with the project plans and aur geofechnical recommendations. <br />1805 - 7i(ith Pl�ic<:.
