ameO <br />AMEC performed seventy -three (73) CQA gradations of SLF. The testing frequency <br />(approximately one test per 705 cubic yards) exceeded the minimum specified testing <br />frequency of one test per 5,000 cubic yards. The CQA gradations performed of SLF met <br />project specifications. The SLF CQA gradation results met project specifications and are <br />summarized in Table 7. <br />AMEC performed eleven (11) CQA gradations of DCF. The testing frequency <br />(approximately one test per 9,362 cubic yards) exceeded the minimum specified testing <br />frequency of one test per 20,000 cubic yards. The DCF CQA gradations met project <br />specifications, and the results are summarized in Table 8. <br />4.1.2 Moisture Content <br />AMEC measured oven moisture contents of SF, LDF, SLF, and DCF as part of the CQA <br />program. Moisture content data are presented in Appendix H -1 and Tables 5 through 8. <br />4.1.3 Atterberg Limits <br />AMEC performed Atterberg limits testing of all fill materials. All fill materials, with the <br />exception of SF and SLF, were non - plastic. The SLF, SF, DCF, and LDF samples tested <br />met project specifications for Atterberg limits. Atterberg limits test data are presented in <br />Appendix H -1. <br />AMEC performed fifty -five (55) CQA Atterberg limits tests of SF. The testing frequency <br />(approximately one test per 45,691 cubic yards) exceeded the minimum specified testing <br />frequency of one test per 50,000 cubic yards. The CQA Atterberg limits performed on SF <br />met project specifications. The SF CQA Atterberg limits results are summarized in Table 5. <br />AMEC performed six (6) CQA Atterberg limits tests of LDF. The testing frequency <br />(approximately one test per 18 cubic yards) exceeded the minimum specified testing <br />frequency of one test per 10,000 cubic yards. The LDF CQA Atterberg limits met project <br />specifications, and the results are summarized in Table 6. <br />AMEC Earth & Environmental, Inc. <br />2000 S Colorado Blvd 2 -1000 <br />Denver, CO 80222 <br />Tel 303 - 935 -6505 <br />Fax 303 - 935 -6575 www.amec com <br />18 <br />
