October 2001 -2- 003-2182.004 <br /> of External Pond construction activities. Record (as-built) drawings for the project are <br /> presented in Appendix A of this report. <br /> 1.2 Construction Quality Assurance/Quality Control <br /> Golder provided Construction Quality Assurance (CQA) and Construction Quality Control <br /> (CQC) monitoring and testing services, and prepared this report describing the monitoring and <br /> test results for the External Pond activities. Photographic documentation of construction <br /> activities is presented in Appendix B. <br /> 1.2.1 CQA Monitoring of Earthworks <br /> Golder provided CQC testing and CQA testing and monitoring of earthworks for the External <br /> Pond Construction. CQA testing and monitoring of earthworks was provided for in-place <br /> materials in accordance with the Golder Earthworks CQA Plan. The earthworks material <br /> specifications for this project are summarized in Table 1. CQC earthworks testing was <br /> provided to support the contractor during the manufacture of materials and prior to material <br /> placement. The CQC test results are not included in this report because these tests were <br /> intended to assist the contractor in materials preparation rather than record testing. <br /> Golder provided CQA laboratory and field testing, and monitored earthworks construction <br /> activities as follows: <br /> ► Golder monitored site grading. Golder monitored slope reduction fill and <br /> fill placement, including lift thickness, compactive effort, and use of <br /> suitable material for Structural Fill. Golder performed CQA laboratory <br /> testing of grain size, Atterberg limits, and moisture content of Structural <br /> Fill. <br /> ► Golder visually monitored subgrade preparation to confirm that the <br /> subgrade surface was unyielding, free of organic matter and other <br /> I\00\2182\EXTERNAL POND RPTTMAL DOC Golder Associates <br />
