WMU FU -03, WMU F -West Leachate Impoundment and Desilting Basin February 2004 <br />Forward Landfill Job No. 021605.03 <br />3.0 CONSTRUCTION QUALITY ASSURNACE PROGRAM <br />3.1 Construction Components <br />Vector provided CQA services on both earthworks and geosynthetic components of the <br />WMU FU -03 construction. The earthwork tasks included excavation, general earthfill <br />and subgrade fill, clay liner placement, granular drainage materials installation, and <br />protective operations layer placement. The geosynthetics tasks included installing the <br />GCL, high-density polyethylene (HDPE) geomembrane, geocomposite, geonet, and <br />geotextile. <br />3.2 CQA Documentation <br />CQA documentation was prepared by Vector as part of the prescribed CQA duties and <br />consisted of a system of daily record keeping including daily progress reports and a <br />record of various test data sheets pertinent to the soils and geosynthetic components of <br />the liner system. Copies of the original records are maintained by Vector and can be <br />made available upon request. <br />Tables 1 and 2, included in this report summarize the soils and geosynthetics testing <br />requirements per the CQA Plan and Technical Specifications. Within each of the <br />tables, information on the construction material type, the total quantity of material <br />placed on the project, the test designation to be performed, the specified testing <br />frequency, the required number of tests to be conducted, the actual number of tests <br />conducted, and the actual testing frequency is listed. As shown on the tables, the <br />actual materials testing frequency on the project satisfies the number of tests required <br />by the CQA Manual. These tables are part of Vector's internal quality control program to <br />ensure that all of the testing and required testing frequencies are satisfied on the <br />project. <br />Other CQA documentation with respect to test data and observation sheets are <br />discussed within the following sections. Copies and summaries of various data for the <br />soils and geosynthetics components monitored and physically tested by Vector are <br />included in various appendices of this report. Documentation of the conformance tests <br />for the geosynthetic components is also presented. <br />Vector Engineering, Inc. - 143E Spring Hill Drive - Grass Valley, CA 95945 - (530) 272-2448 <br />-5- <br />
