amec? <br />Finishing of drain cover fill was performed using two CAT D-6 dozer, a CAT D-8 dozer, and <br />laborers. <br />11) Storm Water Management <br />A) Best Management Practices <br />Best Management Practices are being observed throughout the VLF Phase 5 Project. Ames placed <br />hay bales between stations E8+00 and E23+75 (+/-) for temporary erosion control. <br />III) Material Processing <br />A) Drain Cover Fill Process Area <br />No Drain Cover Fill (DCF) was processed during the week. <br />Location This Week Cumulative Comments <br /> (tons) (tons) <br />DCF Process 0 121,223 <br />Total 0 121,223 <br />IV)VLF Geosynthetics <br />A) Geomembrane Installation <br />1) VLF <br />Geomembrane installation within the Phase 5 VLF continued performing deployment, seaming, <br />and repair/QC activities. Geomembrane installation was performed in the area shown in Figure 3. <br />Approximately 283,831 square feet of secondary 100mil LLDPE was deployed using a John Deere <br />200 excavator and a John Deere 544 front-end loader with spreader-bar attachments. Subgrade was <br />inspected and approved by AMEC and Lone Star representatives prior to geomembrane <br />deployment (see Figure 3). Approximately 12,903 linear feet of seam was fusion welded using two <br />fusion welding machines. Twenty-six destructive test samples were marked during fusion seaming. <br />Non-destructive testing was performed for fusion welded seams. Approximately 1,703 linear feet <br />of seam was extrusion welded using one extrusion welding machine. Five destructive test samples <br />were marked during extrusion seaming. All destructive tests performed were within project <br />specifications. Repairs were performed using the extrusion welding method for all marked defects. <br />Vacuum testing was performed for all extrusion welded seams and repairs. <br />B) Anchor Trench <br />1) VLF <br />PSSA anchor trench excavation continued between stations E6+50 (+/-) and 1310+50 (+/-) as well <br />as between G14+00 (+/-) and G28+00 (+/-) using a CAT 312 excavator and one laborer. The <br />anchor trench was inspected by an AMEC field representative and found to be constructed in <br />accordance with design drawings and project specifications. <br />C) Geomembrane Acceptance <br />1) VLF <br />Secondary 100mil geomembrane (S-561 thru S-585, S-608 thru S-621, and S-638 thru S678) <br />shown on Figure 4 was inspected by AMEC and Lone Star representatives and found to be <br />installed within project specifications and acceptable for continued construction activities. <br />VLF Weekly Report WE 08.28.10.13
