Our services included providing onsite <br />observations and testing on a part-time from January 14 to February 17, 2015. Our <br />repres�ntatives made three site visits to observe building foundation subgrade and test building <br />slab backfill. <br />�ur representative observed building foundation subgrade to be dense and suitab(e for support <br />of the proposed structure. <br />Our representative conducted four field density tests in accordance with ASTM Test <br />Designation D2922 (Nuclear Gauge Method). One representative soi! sample was refiurned 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 iocations of the building slab backfill. <br />Based on our observations and testing, the earthwork construction was accomplished in <br />accordance with the project plans and our geofiechnical recommendations. <br />1805 -'1iht.h �'I<�ce i�l.E., SuiCi' 11J1 m l3ellr:vue, WA 9u0+"'t5 • i4"LS) 449-4704 ° fAX {42�) 449-47i1 <br />
