amE�c <br />Earth & Environmental <br />cast the material over the liner. Drain cover fill placement was also performed using a CAT D -6 <br />LGP (low ground pressure) dozer when access to the area was established. A minimum if 2 feet of <br />cover was placed over the geomembrane. An AMEC representative observed the placement <br />constantly. <br />CQA ACTIVITIES: <br />SUMMARY: <br />The CQA activities performed consisted of observing, documenting and recording the construction <br />activities of the contractor. <br />AMEC observed and documented ambient and fill temperatures, as well as the placement of structural fill <br />within the Phase 5 VLF fill area. <br />AMEC observed and documented ambient and fill temperatures, as well as the structural fill placement <br />(processed ore) within the Phase IV VLF constantly. Nuclear density testing was performed during <br />placement. <br />AMEC observed drain cover fill placement for the Phase IVc re- certification area constantly. <br />AMEC observed construction of the ADR/Crushing waterlines. <br />AMEC observed construction of the Phase 5 primary underdrain. <br />Testing Summary <br />Laboratory testing continues (Particle Size Distribution, Atterberg Limits, and Moisture- Density <br />Compaction testing) for sampled materials. <br />GENERAL PROJECT ITEMS <br />Summary of Concerns: <br />No concerns <br />Summary of Planning Items: <br />Structural fill placement within the Phase 5 VLF footprint will continue. <br />Continue processing soil liner fill at the South Cresson Clay Processing area. <br />Continue subgrade preparation within the Phase 5 VLF footprint. <br />Continue construction of the ADR and Crusher waterlines. <br />Continue drain cover fill placement at the Phase IVc re- certification area. <br />Confirmatory drilling for Underground Workings #3006 and #3007. <br />Continue Phase 5 primary underdrain construction. <br />Summary of Non - conformances: <br />None Issued <br />VLF Weekly Report WE 11.28.09.D.doc <br />
