Storm water <br />controls were maintained throughout the week. Precipitation not substantial throughout the week. <br />V) VLF Primary Underdrain <br />No work performed during the week. <br />VI) Miscellaneous <br />Underdrain filter material stockpiled at the 5-way intersection was hauled to various stockpile areas <br />around the construction site. This was performed using CAT 777 haul trucks loaded by a John Deere <br />850 excavator. Relocating the material was performed to allow the Mine Operations to build a road in <br />the area. <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 construction of the ADR/Crushing waterlines. <br />AMEC observed confirmation drilling at Underground Workings #3006 and #3007 constantly. <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 />VLF Weekly Report WE 12.12.09.D.doc
