All required laboratory tests have been completed and approved. <br />All required Contractor/Liner Subcontractor supplied documentation has been <br />received and approved. <br />All record drawings have been completed and approved. <br />6.2.10 LINER MATERIALS <br />The Geotechnical CQA procedures indicated in this section are intended to allow <br />the installation of materials in contact with the geosynthetics without causing <br />damage to the VFPE. <br />Important points for Quality Assurance of materials in contact with VFPE <br />include: <br />A geotextile or drainage medium approved by the Construction Manager shall <br />be installed above the VFPE. <br />Equipment used for placing soil shall not be driven directly omthe VFPE. <br />In heavily trafficked areas, such as access ramps, soil thickness should be at <br />least three (3) feet. <br />Placement of soils, gravels, sand or other types of earth materials on top of the <br />VFPE shall not be performed until all destructive and nondestructive testing <br />has been performed and accepted. Placement of overlying earth materials <br />shall be performed in a manner to minimize wrinkles. Equipment operators <br />shall be briefed on methods of placement relative to thermal expansion and <br />contraction of the VFPE. <br />Soil material(s) placed on top of the VFPE shall be stockpiled and displaced <br />off the stockpile to create a cascading effect of the material on top of the <br />VFPE. <br />The Geotechnical CQA Monitors shall inform the Geotechnical CQA Officer if <br />"the above conditio-ns"are not fulfilled. <br />7.0 DOCUMENTATION <br />To provide evidence of satisfactory work performance, all stages of liner construction <br />shall be documented. The information shall be recorded on a standardized form or in a <br />bound field logbook. <br />7.1 DAILY RECORD KEEPING <br />The purpose of daily record keeping is to record construction activities, including: <br />results of continuous visual observations; laboratory/field test data; sampling; <br />review of test results; repairs; problems; solutions; and general field activity. The <br />daily record keeping will include a daily field inspection report and a daily test <br />summary report, as discussed below. <br />-31- <br />C:\2001-048\FIN A E COVER CQA.DOC\08/20/01 <br />Geologic Associates <br />
