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:
■ Geomembrane: density (ASTM D1505)
carbon black content (ASTM D1603)
thickness (GRI -GM8)
tensile strength (ASTM D638)
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 Geosynthetics Installation CONTRACTOR.
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;
■ observe that required overlap distances are met;
■ monitor and record ambient air temperatures;
■ verify that no continuous horizontal seams are placed on slopes unless approved by
CERTIFYING ENGINEER; and,
