October 2001 -13- 003-2182.004 <br /> 4.0 EARTHWORK CQA TESTING AND MONITORING <br /> The following sections summarize results of the earthwork CQA testing and monitoring <br /> performed by Golder for the External Pond. <br /> Golder conducted CQC and CQA testing of earth materials used for construction. As discussed <br /> in Section 1.2.1, Golder performed CQC testing to assist the contractor in the manufacture of <br /> materials before installation. This report does not present CQC testing, and CQC tests have not <br /> been included in calculating testing frequencies. Golder performed CQA testing of in-place <br /> materials used for construction of the Phase I, II, and III External Pond. Table 3 presents <br /> specified and observed CQA testing frequencies. Figure 1 shows the coordinate system used to <br /> locate tests. <br /> In accordance with the Golder CQA Plan, when a Golder monitor observed deficiencies, the <br /> monitor determined the nature and extent of the problem and notified Ames and/or CC&V. <br /> When unsatisfactory test results identified a deficiency, Golder performed additional tests to <br /> define the extent of the deficient area. Ames corrected deficiencies to meet the requirements of <br /> the specifications, and Golder re-tested and/or approved the corrected deficiency prior to any <br /> additional related work. The following sections include discussions of the deficiencies <br /> encountered. <br /> 4.1 Results of Laboratory Soils Testing <br /> Golder performed laboratory testing of soils during all aspects of the External Pond <br /> construction. Golder's soils laboratory in Lakewood, Colorado performed permeability testing <br /> of Soil Liner Fill. All other testing was performed on-site. To verify that the earth materials <br /> used during construction met project specifications, Golder performed the following American <br /> Society for Testing and Materials(ASTM)tests: <br /> I\00\2182\EXTERNAL POND RPTTWALDOC Golder Associates <br />
