Our services included providing onsite observations and testing on a part-time from June 17 to June 18, 2015. �ur representatives made two site visits to observe and test the building foundation subgrade. Our representative observed building foundation subgrade to be dense and suitable for support of the proposed structure. Our representative conducted five field density tests in accordance with ASTM Test Designation D2922 (Nuclear Gauge Met�od). One representative soil sample was returned to our laboratory for analysis of the maximum dry density and optimum moisture content in accordance with ASTM D1557-02 (Modified Proctor). Density test results indicate adequate compaction of at least 95 percent at the tested locations af the building slab backfill. Based on our observations and testing, the earthwork construction was accomplished in accordance with the project plans and our geotechnical recommendations. - I ;i)"� I 3f�:Fr P ._�� N.�� t;i'��i� :%i)�I • f�< < � . .,,, l3Ot'" �1;',1 , -�i �,:l�.I ,�i%X ,��_ .�_ �� ,-��; ,�
