performed by the CQA Monitor on -site or in a geotechnical laboratory approved by the CERTIFYING
ENGINEER.
6.01 CONSTRUCTION TESTING:
During construction, the CQA Monitor shall test all earthwork components to verify that the construction is in
accordance with the SPECIFICATIONS. Testing shall be performed on all soil used in the construction to
confirm the materials meet SPECIFICATIONS. The CQA Monitor shall conduct testing after final placement
of the materials. The tests to be performed, and the testing frequency, for each material type are listed in
Tables 1 and 2. The testing frequencies specified in Tables 1 and 2 shall be increased when the CQA Monitor
determines that construction conditions (such as adverse weather, equipment breakdown, improperly ballasted
compactor, excessive lift thickness, improper soil type, improper moisture conditioning and compaction)
warrant additional tests. Additional tests will be approved by MANAGER and directed by the CQA Monitor.
6.02 CONSTRUCTION MONITORING:
The CQA Monitor will monitor and test all earthwork quality assurance components of the construction to
verify that the construction is in accordance with the SPECIFICATIONS. The CQA Monitor shall identify
inadequate construction methodologies or materials that may adversely impact the performance of the facility
being constructed and existing structures. The CQA Monitor will record visual observations throughout the
construction process to ensure that the materials are placed to the minimum dimensions as shown on the
DRAWINGS. Quality control testing will be performed by the CONTRACTOR.
6.02.01 FOUNDATION PREPARATION:
0 The CQA Monitor shall observe and document the foundation preparation including:
■ stripping and excavation activities to ensure that CONTRACTOR places the material in the
appropriate stockpile (Structural Fill, Select Structural Fill, Underdrain Fill, Leak Detection
Fill, Low Volume Solution Collection Fill, Bedding Fill, Soil Liner Fill, Drain Cover Fill,
Fine Shaft Backfill, Pipe Bedding Material and Granular Filter Material), if stockpiling is
necessary;
■ stockpiling activities to verify location of stockpile, material type, and dressing;
■ excavations for moisture seeps, unsuitable foundation soil, elevation, and proper drainage;
■ subgrade preparation to confirm that the surface of the subgrade is free of soft, organic, and
otherwise deleterious materials (such as debris, branches, vegetation, mud, ice, or frozen
materials); and that soil and rock surfaces that contain joints or fractures are adequately filled
in accordance with the SPECIFICATIONS; and
■ construction of access roads, drainage control features and erosion control features to verify
compliance with the DRAWINGS and SPECIFICATIONS.
6.02.02 PLACEMENT OF MATERIALS:
During placement of Structural Fill, Select Structural Fill, Coarse Shaft Backfill, Cemented Rockfill,
Underdrain Fill, Low Volume Solution Collection Fill, Bedding Fill, Leak Detection Fill, Soil Liner Fill, Drain
Cover Fill, Fine Shaft Backfill, Pipe Bedding Material and Granular Filter Material, the CQA Monitor shall:
■ verify the use of appropriate fills;
