WMU D-99 Construction September 1999 <br /> Forward Landfill Job No.986011.02 <br /> 5.3.2 GCL Conformance Testing <br /> Conformance testing of the GCL materials was performed by Vector and <br /> Precision Laboratories. Results of this conformance testing were reviewed by <br /> the Construction Manager and Vector's CQA Monitor prior to placement of the <br /> materials. Select samples of the GCL were cut in the factory and sent to the <br /> laboratory for conformance testing in accordance with the project specifications. <br /> Conformance testing included tests for mass per unit area (ASTM D-5261), swell <br /> index (ASTM D-5890), grab tensile properties (ASTM D-4632), and interface <br /> shear strength (ASTM D-5321). Results of the conformance testing performed <br /> by Vector and Precision indicated that the materials met the requirements of the <br /> project specifications. Detailed test results are provided within Appendix J <br /> (shear test results are included in Appendix G). <br /> 5.3.3 GCL Deployment <br /> Prior to installation of the GCL, the prepared subgrade was accepted by <br /> the liner installer, GSE, as required by the project specifications. GCL panel <br /> deployment in WMU -99 began on July 2, 1999 and was completed on July 20, <br /> 1999. The subgrade of the Leachate Impoundment was completed on August <br /> 13, 1999. GSE began GCL panel deployment on August 16, 1999 with <br /> completion on August 19, 1999. To protect the GCL, HDPE liner was deployed <br /> concurrently with the GCL placement. Deployment was performed in general <br /> conformance with the project specifications. <br /> 5.4 Geomembrane Installation <br /> 5.4.1 Geomembrane Factory Quality Control <br /> Upon arrival by truck shipment, the unloading and storage of the <br /> geomembrane rolls were observed by Vector's CQA Monitor. Each roll of <br /> geomembrane was logged in by roll number and the roll numbers then cross- <br /> checked against the quality control documents provided by the supplier, GSE. <br /> Information regarding the roll number, lot, batch, area, laboratory testing log, and <br /> pass/fail of the sheet was recorded.
