® Verify all manufacturing documentation required by the technical specifications has been received. ® Verify a log of geosynthetics received is completed for all geomembrane materials received. Damaged geomembrane must be rejected. If rejected, verify material is removed from the site or stored at a location, separate from accepted geomembrane. Geomembrane that does not have proper manufacturer's documentation must be stored at a separate location, until all documentation has been received, reviewed, and accepted. 5.2.2 Conformance Testing Prior to manufacturing geomembrane products for this project, the CQA Manager will perform and review one interface shear test for the prepared .subgrade layer soil layer/geomembrane interface and geomembrane/geocomposite interface. Direct Shear Tests will be performed on the sample provided with "submittals for review" from the geosynthetic supplier and in accordance with the testing procedures outlined the specifications and in section 3.0 of this CQA Manual. The roll and lot number from which the geocomposite sample is taken, along with the MQC test data from that lot will be provided. The material properties of the sample provided for direct shear testing, in particular the asperity height, will be used as a basis for accepting the material provided for the project. One geomembrane sample will then be obtained for every 100,000 square feet of material supplied, and at least one for each resin batch. The material must be sampled at the site by the CQA monitor or at the manufacturing plant by an independent third party under the direction of the CQA organization. Samples must be forwarded to an independent testing laboratory for the conformance testing. The CQA monitor must review all conformance test results and report any non-conformance to the County and CQA manager. Perform the following conformance tests on geomembrane: Sheet Thickness (10 per roll) ASTM D5994 Asperity Height(10 both sides per roll) GRI-GM12 Sheet Density ASTM D1505 /D 792 Tensile Properties ASTM D638 Carbon Black Content ASTM D 1603 /D4218 Carbon Black Dispersion ASTM D5596 ' 5.2.3 Review of Installer's Geomembrane Panel Drawings Before installing any geomembrane, the installer must submit shop drawings in accordance with the technical specifications. The shop drawings must show the proposed layout of the panels, including panel identification numbers, field seams, and any other details that do not conform to the construction drawings. The CQA monitor must review these drawings prior to geomembrane installation. CH CQA Plan 041712 Rev2a.doc 5.4 Construction QuaWAssurance Plan
