6.02 GEOMEMBRANE CONFORMANCE TESTING:
Prior to geosynthetic installation, the CQA Monitor shall obtain samples of the geomembrane and geogrid
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 and Section 02776.1,Article 2.01:
■ Geomembrane: density(ASTM D1505)
carbon black content(ASTM D1603)
thickness(ASTM D5199)
tensile strength(ASTM D6693)
shear strength(ASTM D4833)
■ Geogrid: carbon black content(ASTM D4218)
flexural rigidity(ASTM D5732)
junctions strength(GRI GG2)
tensile strength(ASTM D6637)
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;
