Upper Northern Portion of WMU FU-08 September 2009 <br /> Forward Landfill Project No.021605.09 <br /> 3.0 CONSTRUCTION QUALITY ASSURANCE PROGRAM <br /> 3.1 Construction Components <br /> Vector provided CQA services on both earthworks and geosynthetic components <br /> during the construction of the northern portion of WMU FU-08. The elements <br /> monitored by Vector and discussed within this section include general fill (berm <br /> construction), grading, geotextile placement, HDPE geomembrane placement, LCRS <br /> granular drainage layer placement, HDPE pipe installation, and protective <br /> operations soil placement. <br /> 3.2 CQA Documentation <br /> CQA documentation was prepared by Vector as part of the prescribed CQA duties <br /> and consisted of a system of daily record keeping including daily progress reports <br /> and a record of various test data sheets pertinent to the soils and geosynthetic <br /> components of the liner system. Copies of the original records are maintained by <br /> Vector and can be made available upon request. <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 <br /> the soils and geosynthetics components monitored and physically tested by Vector <br /> are included in various appendices of this report. Documentation of the <br /> conformance tests for the geosynthetic components is also presented in the <br /> appendices. <br /> 3.3 Design Modifications <br /> During the construction of upper northern portion of WMU FU-08, modifications to <br /> the contract drawings and specifications occurred. The approved modifications <br /> during construction of WMU FU-08 included modification to the coarse drainage <br /> gravel; the Design Engineer approved a coarser gravel with maximum particle size <br /> of 1.5 inches. <br /> Vector Engineering,Inc.- 143E Spring Hill Drive-Grass Valley,CA 95945-(530)272-2448 <br /> -5- <br />
