Our services included providing onsite observations and testing on a part-time from April 14 to July 28, 2015. Our representatives made six sii:e visits to observe and test the building foundation subgrade. Our represe:ntative observed building foundation subgrade to be dense and suitable for support of the propc�sed structure. Our repres��ntative conducted thirteen field density tests in accordance with ASTM Test Designation D2922 (Nuclear Gauge Method). Two representative soil samples were returned to our labo��atory 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 of the building slab backfill. Based on our observations and testing, the earthwark construction was accomplished in accordance with the project plans and our geotechnical recommendations. _ 1`r�i)�i � 3F�1i1 �'.i�,� i�Lf , 5.�,1:� _ i.l • :iz�� .�c�, `v`�',� `�FiiiU � �,�?51 k-��- 7.i', � i�rl�, t 4 .�d�y �+, � ��b
