June 24,2003 -22- 003-2203.7 <br />• 4.0 EARTHWORK CQA TESTING AND MONITORING <br />The following sections summarize results of the earthwork CQA testing and monitoring performed by <br />Golder for the Phase IVb PSSA. <br />Golder conducted CQA testing of earth materials used for construction. Golder performed CQA <br />testing of in-place materials used for construction of the Phase Nb PSSA. Table 4 presents specified <br />and observed CQA testing frequencies. Figure 1 shows the site plan and coordinate system used to <br />locate tests. <br />In accordance with the Golder CQA Plan, when a Golder monitor observed deficiencies, the monitor <br />determined the nature and extent of the problem and notified Ames and/or CC&V. When <br />unsatisfactory test results identified a deficiency, Golder performed additional tests to define the <br />extent of the deficient area. Ames corrected deficiencies to meet the requirements of the <br />specifications, and Golder retested and/or approved the corrected deficiency prior to any additional <br />related work. The following sections include discussions of the deficiencies encountered. <br />• 4.1 Results of Laboratory Soils Testing <br />Golder performed laboratory testing of soils during all aspects of the Phase IVb PSSA construction. <br />Golder's soils laboratory in Lakewood, Colorado performed permeability and bulk specific gravity <br />testing of SLF. All other testing was performed on-site. To verify that the earth materials used <br />during construction met project specifications, Golder performed the following American Society for <br />Testing and Materials (ASTM) tests: <br />• Rock corrected density values (ASTM D4718); <br />• Grain size distribution (ASTM D1140 for material finer than the No. 200 sieve, <br />and ASTM C117 and C136 for coarse material); <br />• Moisture content (ASTM D2216); <br />• Atterberg limits (ASTM D4318); <br />• Standard Proctor compaction (ASTM D698); <br />• Permeability (ASTM D5084, Method D); <br />. • In-place density testing (ASTM D2922); <br />L100\3203\Ud000~'olCenPSSg06R3\003230.i.Od00.0]}ORep.doa Golder Associates <br />
