amecIO <br />H14+00 (+/-), approximately 0 to 300 feet left of centerline using two CAT D-6 LGP dozers <br />and two CAT D-8 dozers. <br />C) Cut to Fill <br />1) VLF <br />Structural fill was placed between stations J 10+00 (+/-) and J 10+75 (+/-), approximately 200 <br />to 250 feet left of centerline. Structural fill was placed in 18" to 24" lifts using various CAT <br />dozes. Each lift was moisture conditioned using a tandem axle water truck (when necessary) <br />and compacted using a 10-ton vibratory smooth drum compactor, passing over the entire fill <br />surface at least 4 times (method compaction technique was applicable). Fill temperatures were <br />monitored by an AMEC field representative during ambient temperatures below 32°F and <br />found be acceptable. <br />D) Soil Liner Fill <br />1) VLF <br />No work performed during the week. <br />E) High Volume Solution Collection System <br />1) High Volume Solution Collection Piping <br />No placement performed during the week. <br />2) Drain Cover Fill (DCF) <br />No work performed during the week. <br />F) Leak Detection Trench <br />1) VLF <br />Excavation of the leak detection trench continued between stations H11+00 (+/-) and H20+50 <br />(+/-), approximately 150 feet left of centerline. The excavated material was stockpiled to the <br />west of the excavation and will be used for slope contouring in the area. A portion of the leak <br />detection system was installed between stations H15+00 (+/-) to H20+50 (+/-) approximately <br />150 left of centerline. The 1'x1' trench was excavated using a CAT 312 excavator. 40mi1 <br />HDPE geomembrane and 12oz/ffz geotextile were placed in the trench. Three-inch CPe pipe <br />was then placed over the geotextile. Approved leak detection fill (LDF) was placed in the <br />trench using a CAT 950 front-end loader and laborers. The geotextile was wrapped and <br />overlapped, encapsulating the LDF and 3" CPe pipe. SLF material was then placed over the <br />trench. Leak detection trench construction was observed and inspected by an AMEC field <br />representative and found to be constructed in accordance with design drawing and project <br />specifications. <br />II) Storm Water Management <br />A) Best Management Practices <br />Best Management Practices are being observed throughout the Phase 5 VLF Project. <br />VLF Weekly Report WE 05.14.2011
