D) Geomembrane Acceptance <br />1) VLF <br />No geomembrane was accepted during the week. <br />E) Geomembrane Delivery <br />1) VLF <br />No geomembrane was delivered during the week. <br />ame <br />IV)VLF Geosynthetics <br />A) Geomembrane Installation <br />1) VLF <br />Geomembrane installation within the Phase 5 VLF resumed performing deployment, and <br />seaming. Geomembrane installation was performed in the area shown in Figure 3. <br />Approximately 180,473 square feet of 80mil LLDPE was deployed using a John Deere 200 <br />excavator and a John Deere 544 front -end loader with spreader -bar attachments. Subgrade was <br />inspected and approved by AMEC and Lonestar representatives prior to geomembrane <br />deployment (see Figure 3). Approximately 9,230 linear feet of seam was fusion welded using <br />four fusion welding machine. Nineteen destructive test samples were marked during fusion <br />seaming. Approximately 615 linear feet of seam was extrusion welded using two extrusion <br />welding machine. Two destructive test samples were marked during extrusion seaming. All <br />destructive tests performed were within project specifications. Non - destructive testing was <br />performed for fusion welded seams. Repairs were performed using the extrusion welding <br />method for all marked defects. Vacuum testing was performed for all extrusion welded seams <br />and repairs. <br />B) Geomembrane Exposure <br />1) VLF <br />Exposure of previously installed geomembrane near station J3 +00 ( + / -), near centerline, was <br />performed using a John Deere 35D excavator and laborers. This was performed preparing to <br />tie -in to the geomembrane when installation. An AMEC field representative observed the <br />geomembrane exposure constantly. <br />C) Anchor Trench <br />1) VLF <br />Excavation of the existing anchor trench between stations E6 +00 ( + / -) and E8 +00 ( + / -), near <br />centerline, was performed to allow for soil liner fill (SLF) placement in the area. This was <br />performed using a John Deere 35D and laborers. An AMEC field representative observed the <br />anchor trench excavation constantly. The full depth of the anchor trench was excavated were <br />saturated SLF was encountered. <br />Temporary anchor trench excavation continued between stations H11+00 ( + / -) and H 16 +00 <br />( + / -) using a John Deere 35D excavator and one laborer. This was performed to allow for <br />geomembrane deployment. The anchor trench was inspected by an AMEC field representative <br />and found to be constructed in accordance with design drawings and project specifications. <br />VLF Weekly Report WE 06.18.2011 <br />
