ameO <br />4.0 EARTHWORK CQA TESTING AND MONITORING <br />The following sections summarize results of the earthwork CQA testing and monitoring <br />performed by AMEC for the Phase 5 Berm Modification. <br />AMEC conducted CQA testing of earthwork materials used for construction. AMEC <br />performed CQA testing of in -place materials used for construction of the Phase 5 Berm <br />Modification. Table 4 presents specified and observed CQA testing frequencies. Figure 1 <br />shows the site plan and coordinate system used to locate tests. <br />In accordance with the AMEC Earthworks CQA Plan (Section 1400.1 of the Specifications), <br />when an AMEC monitor observed deficiencies, the monitor determined the nature and <br />extent of the problem and notified Ames and /or CC &V. When unsatisfactory test results <br />identified a deficiency, AMEC performed additional tests to define the extent of the deficient <br />area. Ames corrected deficiencies to meet the requirements of the specifications, and <br />AMEC retested and /or approved the corrected deficiency prior to any additional related <br />work. The following sections include discussions of the deficiencies encountered. <br />4.1 Results of Laboratory Soils Testing <br />AMEC performed laboratory testing of soils during all earthworks aspects of the Phase 5 <br />Berm Modification construction. AMEC's on -site soils laboratory at CC &V performed the <br />material testing. To verify that the earthwork materials used during construction met project <br />specifications, AMEC performed the following American Society for Testing and Materials <br />(ASTM) tests: <br />• Rock corrected density values (ASTM D4718); <br />• Grain size distribution (ASTM D1140 for material finer than the No. 200 <br />sieve, and ASTM C117 and C136 for coarse material); <br />• Moisture content (ASTM D2216); <br />• Atterberg limits (ASTM D4318); <br />AMEC Environment & Infrastructure, Inc. <br />2000 S.
