Newmont Goldcorp-Cripple Creek&Victor Gold Mine ■ <br /> Technical Specification No.01400 EARTHWORK CQA ■ <br /> VLF2 Phase 3 <br /> Project No.475.0106.033 <br /> December 5,2019 <br /> 6.1. Construction Testing <br /> During construction, the CQA MONITOR shall test all earthwork components to verify that the <br /> construction is in accordance with the SPECIFICATIONS. Testing shall be performed on all soil <br /> used in the construction to confirm the materials meet SPECIFICATIONS. The CQA MONITOR <br /> shall conduct testing after final placement of the materials. The tests to be performed, and the <br /> testing frequency, for each material type are listed in Tables 1 and 2. The testing frequencies <br /> specified in Tables 1 and 2 shall be increased when the CQA MONITOR determines that <br /> construction conditions (such as adverse weather, equipment breakdown, improperly ballasted <br /> compactor, excessive lift thickness, improper soil type, improper moisture conditioning and <br /> compaction) warrant additional tests. Additional tests will be approved by MANAGER and <br /> directed by the CQA MONITOR. <br /> 6.2. Construction Monitoring <br /> The CQA MONITOR will monitor and test all earthwork quality assurance components of the <br /> construction to verify that the construction is in accordance with the SPECIFICATIONS. The CQA <br /> MONITOR shall identify inadequate construction methodologies or materials that may <br /> adversely impact the performance of the facility being constructed and existing structures. The <br /> CQA MONITOR will record visual observations throughout the construction process to ensure <br /> that the materials are placed to the minimum dimensions as shown on the DRAWINGS. Quality <br /> control testing will be performed by the CONTRACTOR. <br /> 6.2.1. Foundation Preparation <br /> The CQA MONITOR shall observe and document the foundation preparation including: <br /> ■ stripping and excavation activities to ensure that CONTRACTOR places the material in the <br /> appropriate stockpile (Structural Fill, Select Structural Fill, Leak Detection Fill, Low Volume <br /> Solution Collection Fill, Bedding Fill, Soil Liner Fill, Drain Cover Fill, Fine Shaft Backfill, Pipe <br /> Bedding Material and Granular Filter Material), if stockpiling is necessary; <br /> ■ stockpiling activities to verify location of stockpile, material type, and dressing; <br /> ■ excavations for moisture seeps, unsuitable foundation soil, elevation, and proper drainage; <br /> ■ subgrade preparation to confirm that the surface of the subgrade is free of soft, organic, <br /> and otherwise deleterious materials (such as debris, branches, vegetation, mud, ice, or <br /> frozen materials); and that soil and rock surfaces that contain joints or fractures are <br /> adequately filled in accordance with the SPECIFICATIONS; and <br /> ■ construction of access roads, drainage control features and erosion control features to <br /> verify compliance with the DRAWINGS and SPECIFICATIONS. <br /> Page 6 <br />
