amec--�7 <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 subgrade preparation within the Mill Site Earthworks project prior to overburden fill <br />placement. Subgrade temperatures were monitored prior to fill placement. <br />AMEC observed excavation and placement of overburden fill within the Mill Site Earthworks project. <br />Ambient, existing, and placed fill temperatures were monitored throughout the week. <br />AMEC observed slope contouring of placed overburden fill for the Mill Site Earthworks project. <br />AMEC observed remediation of UG #4052. <br />AMEC observed remediation of UG #4077 (The Wedge). <br />AMEC observed confirmatory drilling at UG #4081. <br />AMEC observed remediation of UG #4081. <br />AMEC observed remediation of UG #4083. <br />AMEC observed remediation of UG #4089. <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 />GENERAL PROJECT ITEMS <br />Summary of Concerns: <br />No concerns <br />Summary of Planning Items: <br />Continue clear and grub activities for the Mill Site Earthworks project <br />Continue subgrade preparation for fill placement for the Mill Site Earthworks project. <br />Continue slope contouring for the Mill Site Earthworks project. <br />Continue overburden fill placement for the Mill Site Earthworks project. <br />Continue confirmatory drilling of Underground Workings for the Mill Site Earthworks project. <br />Continue grouting "miss" (non -void) holes from confirmatory drilling. <br />Continue investigation and remediation of Underground Workings for the Mill Site Earthworks project. <br />Continue construction of the catch berm and storm water channel for the Mill Site Earthworks project. <br />Summary of Non - conformances: <br />None Issued <br />MEW Weekly Report WE 05.26.2012 <br />
