All construction materials <br />placed were verified as suitable, and construction methods were in accordance with project <br />technical specifications. <br />Structural Fill: <br />The following Structural Fill haul to fill and grading activities occurred: <br />Cat dozers finish graded the slope between the following benches in Phase 1: A and C, C and E, <br />E and G, and G and Q. The dozer was supported by a Cat excavator with attached rock <br />hammer, breaking oversized rock. A Cat smooth drum roller compacted the finished subgrade. <br />Cat dozers placed cut —to -fill on the slope between the K and M benches upslope of <br />approximately stations K6+00 through K16+00. Cat dozers also placed cut -to -fill on the slope <br />between the I and M benches upslope of approximately stations 110+00 through 118+00. A Cat <br />smooth drum roller compacted the fill areas. <br />Cat dozers and a Cat excavator cut and graded the back -slope of the Phase 2 Sediment <br />Detention Pond located in the vicinity of the Phase 2 Surface Water Diversion Channel station <br />Days <br />S I <br />M <br />T <br />W <br />T <br />F <br />S <br />Work Shifts <br />D <br />D <br />D <br />D <br />D <br />D <br />D=Day Shift N=Night Shift W= Weather <br />Ambient Temperature Ranges During Week Weather Conditions During Week: <br />Highs: 39°F to 60°F Cloud Cover: Clear to cloudy <br />Lows: 26°F to 34°F Precipitation: Rain <br />Wind: Calm to moderate <br />Ames: Continuing construction tasks for the Valley Leach Facility (VLF) <br />Planning: Continuing construction activities and scheduling for the VLF. <br />CONSTRUCTION ACTIVITIES AND PROGRESS: <br />1) Earthworks <br />A) VLF (PSSA, Phase 1, and 2) <br />Note: An Amec Foster Wheeler field professional monitored fill material temperatures during fill <br />placement; average structural fill temperatures were above 32°F.
