<br />Section 01400.2 Page 6 of 11 January 14, 2011 <br />Geosynthetic CQA Plan Revision 0 <br /> <br />S:\Projects\1125G Squaw Gulch Valley Leach Facililty Design\I - Tech Specs\01400.2.r0.doc <br /> <br />6.02 GEOMEMBRANE CONFORMANCE TESTING: <br /> Prior to geosynthetic installation, the CQA Monitor shall obtain samples of the geomembrane for <br />conformance testing to confirm that these materials meet project requirements. The conformance testing <br />frequency shall be at a rate of 1 test per 150,000 square feet. Samples shall be taken across the entire width <br />of the roll and shall not include the first 3 feet. The samples shall be 3 feet wide by the roll width. The <br />CQA Monitor shall mark the machine direction, roll number on the sample, and date the sample was <br />obtained and forward the sample to a third party geosynthetic laboratory. As a minimum, the following <br />conformance tests shall be conducted; with project requirements outlined in Section 02776, Article 2.01: <br /> Geomembrane: density (ASTM D1505) <br /> carbon black content (ASTM D1603) <br /> thickness (ASTM D5199) <br /> tensile strength (ASTM D6693) <br /> All conformance tests shall be performed in compliance with the project SPECIFICATIONS. The CQA <br />Monitor shall review the test results and shall report any nonconformance to the MANAGER, <br />CERTIFYING ENGINEER and the Geosynthetics Installation CONTRACTOR. <br />6.03 CONSTRUCTION MONITORING AND TESTING: <br /> The CQA Monitor shall monitor and test all geosynthetic components of the construction to verify that the <br />construction is in compliance with the project SPECIFICATIONS. The CQA Monitor shall identify <br />inadequate construction methodologies or materials which may adversely impact the performance of the <br />facility being constructed and existing structures. Visual observations throughout the construction process <br />shall be made to ensure that the materials are placed to the lines and grades as shown on the DRAWINGS. <br /> The CQA monitor shall review the following submittals by INSTALLER during the project: <br /> verification that a qualified land surveyor has verified all lines and grades; and <br /> subgrade surface acceptance certificates for each area to be covered by the lining system, <br />signed by the INSTALLER. <br /> The CQA Monitor shall: <br /> Inspect all geosynthetic materials delivered to site. The CQA Monitor shall document any <br />damage and notify MANAGER; <br /> obtain geosynthetic packaging identification slips for verification and generation of an on-site <br />materials inventory; <br /> observe subgrade conditions prior to geosynthetics installation and verify that any <br />deficiencies, as defined in Section 02200 of the SPECIFICATIONS, are corrected; <br /> observe permanent anchoring of geosynthetics to verify that design and project <br />SPECIFICATIONS are met;
