amec <br />Earth & Environmental <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 geomembrane exposure at the Phase IVc re- certification constantly. <br />AMEC inspected and approved the soil liner fill surface at the Phase IVa and Phase IVc re- certification <br />areas. <br />AMEC observed geomembrane installation for the Phase IVa and Phase IVc re- certification areas <br />constantly. <br />AMEC observed the anchor trench backfill at the Phase IVa re- certification constantly. <br />AMEC inspected and approved the installed and existing geomembrane Phase IVa and Phase 1Vc re- <br />certification. <br />AMEC observed drain cover fill placement for the Phase lVa and Phase IVc re- certification areas <br />constantly. <br />AMEC observed construction of the ADR/Crushing waterlines. <br />AMEC inspected encountered underground workings within the Phase 5 VLF. <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 />VLF Weekly Report WE 11.14.09.D.doc <br />
