Clearing and Grubbing <br /> The footprint of the Phase 2A Part 3 Squaw Gulch VLF was stripped of all deleterious materials. <br /> Any soil containing vegetation was removed and placed in several site topsoil stockpiles <br /> designated by CC&V. All cleared areas were inspected by the CQA Monitor to ensure that all <br /> deleterious material was removed prior to further construction activities. <br /> 2.2. Site Grading <br /> Approximately 1,323 cy of Structural Fill (SF) material was used to grade the site within the limits <br /> of Squaw Gulch VLF Phase 2A Part 3 area. Prior to SF placement, the existing subgrade was <br /> scarified to a depth of 6 inches, moisture conditioned, and compacted, as required. The SF was <br /> then placed in maximum 2-foot thick loose lifts, moisture conditioned as required, and <br /> compacted using a 12-ton vibratory sheepsfoot drum compactor. The entire surface of each lift <br /> was compacted with a minimum of four passes in accordance with the developed method <br /> specifications. The development of the method specifications is described in Appendix D. All <br /> subgrade preparation and SF placement associated with site grading was monitored by the CQA <br /> Monitor to ensure that it met the project Technical Specifications. <br /> 2.3. Subgrade Preparation <br /> The subgrade was prepared and inspected prior to SLF placement.The exposed subgrade surface <br /> was moisture conditioned and compacted using a 12-ton sheepsfoot drum vibratory compactor <br /> where needed. Compaction of the subgrade was performed in accordance with the applicable <br /> developed method specifications, presented in Appendix D, for a 12-ton vibratory sheepsfoot <br /> drum compactor. The CQA Monitor inspected and approved the finished subgrade surface prior <br /> to SLF placement. <br /> P:\Projects\0106.032 VLF2 Phase 2 CQA\J-REPORTS\Cert Report-Phase 2A Part 3\475.0106.032 CCV PHASE 2A Part 3 ROC <br /> REPORT.docx <br /> Page 4 <br />
