Wood bros continued to grade the Drainage aggregate for the LCRS system utilizing the D6LGP with a laborer watching for wrinkles. Wood Bros. D&E smooth drum rolled areas of the subgrade that were to be lined today. D&E continued installation of Bentofix NWL 35 GCL rolls and 60mil double textured liner. D&E continued to deploy on the eastern floor of Module 1. D&E installed a total of 30 panels of GCL totaling approximately 60,780ft2 and 14 panels of geomembrane totaling approximately 62,150ft2 all panels were overlapped and seamed per specifications. D&E performed air tests on the tie-in seam and liner deployed 9-24-03. D&E performed repairs to material deployed 9-22/9-23. D&E placed sandbags as ballast on the liner edges prior to leaving the site. D&E tracked the failing destructive sample to 240' off of the west end of seam. D&E started welding a cap strip on seam 108/222 where Destructive sample 113 failed. Vector Engineering, Inc. CQA attended the weekly construction meting. CQA observed placement and grading on the LCRS drainage aggregate imported today. CQA observed and logged subgrade acceptance, panel deployment, seaming, airtests, repairs and vacuum tests performed on the liner materials. CQA observed the drainage aggregate was clean. CQA marked destructive samples for conformance testing. CQA tested destructive sample 113B with results meeting the required specifications for this project Vector discussed with Wood concrete for the leachate containment pad should start on Monday. CQA would like some areas of subgrade around the sump rolled to smooth the subgrade was disturbed due to traffic. v File Name: Foothill Landfill Prepared By Frank Dell -Era Reviewed
