6.02 GEOMEMBRANE CONFORMANCE TESTING: • Geomembrane: density (ASTM D1505) carbon black content (ASTM D1603) thickness (ASTM D5199) tensile strength (ASTM D6693) shear strength (ASTM D4833) amec9 Prior to geosynthetic installation, the CQA Monitor shall obtain samples of the geomembrane for conformance testing to confirm that these materials meet project requirements. The conformance testing frequency shall be at a rate of 1 test per 150,000 square feet or 1 test per resin lot, whichever is greater. Samples shall be taken across the entire width of the roll and shall not include the first 3 feet. The samples shall be 3 feet wide by the roll width. The CQA Monitor shall mark the machine direction, roll number on the sample, and date the sample was obtained and forward the sample to a third party geosynthetic laboratory. As a minimum, the following conformance tests shall be conducted; with project requirements outlined in Section 02776, Article 2.01: All conformance tests shall be performed in compliance with the project SPECIFICATIONS. The CQA Monitor shall review the test results and shall report any nonconformance to the MANAGER, CERTIFYING ENGINEER and the INSTALLER. 6.03 CONSTRUCTION MONITORING AND TESTING: The CQA Monitor shall monitor and test all geosynthetic components of the construction to verify that the construction is in compliance with the project SPECIFICATIONS. The CQA Monitor shall identify inadequate construction methodologies or materials which may adversely impact the performance of the facility being constructed and existing structures. Visual observations throughout the construction process shall be made to ensure that the materials are placed to the lines and grades as shown on the DRAWINGS. The CQA monitor shall review the following submittals by INSTALLER during the project: • verification that a qualified land surveyor has verified all lines and grades; and • subgrade surface acceptance certificates for each area to be covered by the lining system, signed by the INSTALLER. The CQA Monitor shall: • Inspect all geosynthetic materials delivered to site. The CQA Monitor shall document any damage and notify MANAGER; • obtain geosynthetic packaging identification slips for verification and generation of an on -site materials inventory; • observe subgrade conditions prior to geosynthetics installation and verify that any deficiencies, as defined in Section 02200 of the SPECIFICATIONS, are corrected; • observe permanent anchoring of geosynthetics to verify that design and project SPECIFICATIONS are met; Section 01400.2 Page 6 of 11 Geosynthetic CQA Plan June 19, 2012 Revision 1
