amec! <br />Earth & Environmental <br />Ill C) Geomembrane Delivery <br />1) VLF <br />No geomembrane delivered to site during the shift. <br />• <br />• <br />D) Anchor Trench <br />1) VLF <br />Backfilling of the PSSA anchor trench continued between stations E0 +00 ( + / -) and E3 +50 <br />( + / -). The anchor trench was backfilled using a John Deere 35D excavator, a CAT skid steer <br />loader, and laborers. Structural fill (Ore) was moisture conditioned using a tandem axle water <br />truck and placed in the trench in one -foot compacted lifts. Compaction was performed using a <br />vibratory plate compactor. <br />CQA ACTIVITIES: <br />Anchor trench excavation continued between stations E21 +50 ( + / -) and E23 +50 ( + / -) using a <br />John Deere 35D excavator. The anchor trench was inspected by an AMEC field representative <br />and was found to be constructed in accordance to the project design and specifications. <br />SUMMARY: <br />The CQA activities performed consisted of observing, documenting and recording the construction <br />activities of the contractor. <br />AMEC inspected and approved subgrade prior to SLF placement within the Phase 5 VLF. <br />AMEC observed, performed necessary testing, obtained moisture samples, and assisted in the placement <br />and moisture conditioning of SLF material within the Phase 5 VLF. This included the PSSA anchor trench <br />backfill. <br />AMEC inspected and approved subgrade for geomembrane deployment within the Phase 5 VLF. <br />AMEC observed, logged data, and assisted in the installation of geomembrane within the Phase 5 VLF. <br />AMEC observed and inspected PSSA anchor trench excavation. <br />AMEC inspected and accepted the PSSA anchor trench for backfill within the Phase 5 VLF. <br />AMEC observed, obtained samples, and assisted in the process of SLF material at the East Cresson Clay <br />Borrow. <br />AMEC observed, obtained samples, and assisted in the process of DCF material at the DCF Process area. <br />Testing Summary <br />Laboratory testing continued (Particle Size Distribution, Atterberg Limits, Moisture - Density Relations, <br />Specific Gravity, Permeability, and Point Load testing) for sampled materials. <br />VLF Weekly Report WE 07.24.10.D <br />
