n <br />Foothill Sanitary Landfill — Module 1 December 2003 <br />County of San Joaquin Job No 031602 00 02 <br />• Anchor Trenches and Sumps <br />Prior to commencement of geomembrane installation, Vector's CQA Monitor verified <br />that the anchor trenches and sumps were suitable for geomembrane installation and <br />free of loose soil or deleterious material. After completion of geosynthetics deployment, <br />Vector's CQA Monitor verified and documented that the backfill for the anchor trenches <br />was placed and compacted in accordance with the Technical Specifications and no <br />damage occurred to the geosynthetic materials. <br />5.3.2.2 Geomembrane Deployment <br />® Layout Drawing <br />The liner subcontractor, D & E, produced layout drawings that showed the general <br />panel configurations and dimensions. These layout drawings were approved by Vector <br />prior to the installation of the HDPE geomembrane. <br />• Field Panel Identification <br />Prior to geomembrane deployment, Vector's CQA Monitor and D & E discussed and <br />agreed to an identification code for each panel to be deployed. During the deployment, <br />Vector's CQA Monitors verified that the subcontractor marked all the panels and that <br />each panel placed was marked with the manufacturer's roll number. <br />• Field Panel Placement <br />Panel deployment for Module 1 began concurrently with the GCL deployment. During <br />the panel placement, Vector's CQA Monitor(s) kept panel deployment logs. These logs <br />recorded the location (panel number and roll number), installation schedule (date and <br />time), weather conditions (temperature and wind), and thickness of the sheet. These <br />panel deployment logs are presented within Appendix J. <br />Vector Engineering, Inc. • 143E Spring Hill Drive • Grass Valley, CA 95945 • (530) 272-2448 <br />28 <br />
