Clearing and Grubbing <br /> The footprint of the Phase 2A Part 2 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 130,140 cy of Structural Fill (SF) material was used to grade the site within the <br /> limits of Squaw Gulch VLF Phase 2A. Prior to SF placement,the existing subgrade was scarified to <br /> a depth of 6 inches, moisture conditioned, and compacted, as required. The SF was then placed <br /> in 2-foot thick loose lifts, moisture conditioned as required, and compacted using a 12-ton <br /> vibratory sheepsfoot drum compactor. The entire surface of each lift was compacted with a <br /> minimum of four passes in accordance with the developed method specifications. The <br /> development of the method specifications is described in Appendix D. All subgrade preparation <br /> and SF placement associated with site grading was monitored by the CQA Monitor to ensure that <br /> 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 /> P.\Projects\Cert Report-Phase 2A Part 2\475.0106.032 CCV PHASE 2A Part 2 ROC REPORT docx <br /> Page 2 <br />
