Our services included providing ansite <br />observations and testing on a part-time from May 14 to June 1, 2015. Our representatives <br />made two site visits to observe building foundation subgrade and test building slab backfill. <br />Our representative observed building foundation subgrade to be dense and suitable for support <br />of the proposed structure. <br />Our representative conducted eight field density tests in accordance with ASTM Test <br />Designation D2922 (Nuclear Gauge Method). OneZx representative soil sample was returned <br />to 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 />18C�� - i�6i�� (' arc� i�.�., S��ilt� 20l • 3ellc�.�uc, Vti � 9���0`� • i4L5j -�-t�i- i��)� • F,�X f+�_;j 449��7'll � - <br />
