ENVIRONMENTAL <br /> INVESTIGATION &ACTION, INC. <br /> March 21, 1994 <br /> Ms. Sonya Baird <br /> Department of Defense <br /> Office of Contracting, Contracting Division <br /> DDRW, PO BOX 960001 <br /> Stocton, CA 95296-0800 <br /> RE: SOLICITATION NO. DLA005-93-C-0011 - UST REMOVALS <br /> COMPACTION TEST RESULTS <br /> Dear Ms. Baird r <br /> A series of in-place density (compaction) tests were taken at the <br /> subject project on November 17 thru December 2, 1993. These <br /> compaction tests were taken in the excavation of the former <br /> underground storage tank (UST) locations as shown on the contract <br /> drawings. <br /> Field testing was accomplished by the sand volume method, ASTM <br /> 1556. The maximum density/optimum moisture relationship was <br /> established by the ASTM D1557 test method. Testing was done during <br /> compaction operations. <br /> A .summary of the results of all tests performed is attached. The <br /> field density tests were taken at random locations and do not <br /> necessarily represent uniform compaction within the backfill. <br /> The tests, as previously described, were conducted in accordance <br /> with generally accepted soil testing practices. No other warranty, <br /> expressed or implied, is made. <br /> Respectf ly submitted, <br /> Dan Patterson <br /> Project Engineer <br /> I have reviewed and approved the data contained in thig compaction <br /> report. <br /> n ,cc,, <br /> IN <br /> P <br /> No, (,149'1515 <br /> P31 <br /> Scott A.
