The Technical Specifications and Construction Drawings are <br /> presented in Appendix A and in Appendix B, respectively. <br /> 1.4. Record Construction Drawing <br /> The Record Construction Drawings consist of topographic maps of the finished grade surfaces <br /> ' and provide sufficient detail to allow for verification of the various project elements including <br /> elevation, grade and location. The Record Construction Drawings prepared by NewFields, as <br /> well as an as-built surface provided by the Foresight West, is presented on Figure 1. Foresight <br /> West's Professional Land Surveyors License is presented in Appendix C. <br /> 2. PROJECT DESCRIPTION <br /> The project site is located at the Cripple Creek and Victor Gold Mine in Teller County near <br /> Cripple Creek, Colorado. The HGM Platform Extension construction activities included SSF <br /> placement performed in August 2017 to allow for the addition of a Concentrate Load Out <br /> 1 Structure to the existing mill facilities. <br /> 3. EARTHWORK PROCEDURES, OBSERVATIONS, &TESTING <br /> Testing of the earthwork materials used in the construction associated with the High Grade Mill <br /> Platform Extension was performed in accordance with current American Society for Testing and <br /> ' Materials (ASTM) procedures. The requirements for testing frequency and test methods for <br /> earthwork were based on information contained in the project Technical Specifications. The fill <br /> materials were placed using a compaction method specification in lue of nuclear density <br /> testing, due to the material containing more than 30 percent of particles greater than %-inch in <br /> diameter. A compaction method specification was developed on August 4, 2017 in the area <br /> proposed to receive fill by the Contractor. The CQA Monitor observed and approved the <br /> compaction technique. Development of the compaction method specification is presented in <br /> ' Appendix D. <br /> Laboratory testing was performed by Earth Engineering Consultants in their geotechnical <br /> ' laboratory located in Colorado Springs, Colorado. SSF laboratory test results are summarized in <br /> Table 1 and presented in Appendix E. <br /> ' 3.1. Subgrade <br /> The SSF material was placed on previously approved Structural Fill placed during construction <br /> of the Ball Mill Platform and Squaw Gulch VLF Phase 1. The existing subgrade in flat areas was <br /> scarified to a depth of 6 inches, moisture conditioned, and re-compacted in accordance with <br /> Page 3 <br />
