• review all the previous day's accomplishments and activities;
• review scheduled work location and activities for the day; and,
• discuss any problems or potential construction problems.
• This meeting will be documented by the CQA Monitor.
5.03 DEFICIENCY MEETINGS:
Special meetings will be held, as needed, to discuss potential problems or deficiencies. At a minimum,
these meetings will be attended by the CQA Monitor and INSTALLER or CONTRACTOR. If the
problem relates to a design issue, the MANAGER, DESIGN ENGINEER and CERTIFYING
ENGINEER should also be present. The meeting will be documented by the CQA Monitor.
PART 6.0 GEOSYNTHETICS CONSTRUCTION QUALITY ASSURANCE
Construction of the valley leach facility or specified geosynthetics must be in compliance with the
design plans and SPECIFICATIONS. CC&V shall implement a CQA monitoring and testing program
to ensure construction compliance by the CONTRACTOR. The quality assurance program shall
consist of reviewing CONTRACTOR quality control submittals, material conformance testing,
construction monitoring and testing.
The types of geosynthetics used in the valley leach facility construction include polyethylene pipe,
geomembrane and geotextile. These geosynthetics are defined in the project SPECIFICATIONS.
Prior to and during construction, these geosynthetics shall be sampled and tested to determine if they
meet project SPECIFICATIONS. All tests shall be performed in a geosynthetics laboratory approved
by the MANAGER.
6.01 REVIEW QUALITY CONTROL SUBMITTALS:
Prior to geosynthetic installation, the CQA Monitor shall review the INSTALLER'S quality control
submittals to evaluate or confirm that these materials meet project requirements. The CQA Monitor
shall review the QC submittals that are outlined in Section 2776 (Geomembrane) and Section 02777
(Geotextile) of the SPECIFICATIONS.
6.02 GEOMEMBRANE CONFORMANCE TESTING:
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. 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:
• 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.
