Our services included providing onsite <br />observations and testing on a part-time from June 17 to June 18, 2015. Our representatives <br />made two site visits to observe and test the building foundation subgrade. <br />Our representative observed building foundation subgrade to be dense and suitable for support <br />of the proposed structure. <br />Our representative conducted five field density tests in accordance with ASTM Test <br />Designation D2922 (Nuclear Gauge Method). 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 observations and testing, the earthwork construction was accomplished in <br />accordance with the project plans and our geotechnical recommendations. <br />� _ <br />1;50_, t�ffilNi P;a���� � E.; 4t.i��e�. _i)1 + Bciic v�iE=, th;�l �J,s!){; ,• l� ;) �4 ;9-�4; f)� • FAX �� �� 44'�a 4; i i _— � <br />, <br />
