Geomembrane installation was performed in the area shown on <br />Figure 3. Approximately 359,778 square feet of 80mil LLDPE was deployed using a Komatsu <br />200 excavator and a John Deere 544 front -end loader with spreader -bar attachments. Subgrade <br />was inspected and approved by AMEC and Lonestar representatives prior to geomembrane <br />deployment (see Figure 3). Approximately 19,467 linear feet of seam was fusion welded using <br />three fusion welding machine /welding technician combinations. Forty-four destructive test <br />samples were marked during fusion seaming. Approximately 219 linear feet of seam was <br />extrusion welded using two extrusion welding machine /welding technician combinations. <br />Three destructive test samples were marked during extrusion seaming. All destructive tests <br />performed were within project specifications. Non - destructive testing was performed for fusion <br />welded seams. Repairs were performed using the extrusion welding method for all marked <br />defects. Vacuum testing was performed for all extrusion welded seams and repairs. <br />During the Cresson blast, an AMEC field representative observed the geomembrane and no <br />damage was noted. <br />B) Geomembrane Exposure <br />1) VLF <br />No work performed during the shift. <br />C) Anchor Trench <br />1) VLF <br />Temporary anchor trench excavation continued between stations A0 +00 ( + / -) and A4 +00 ( + / -), and <br />between stations A36 +00 ( + / -) and A49 +00 ( + / -) using a John Deere 35D excavator and one <br />laborer. The anchor trench was inspected by an AMEC field representative and found to be <br />constructed in accordance with design drawings and project specifications. <br />Anchor trench backfill was performed between stations H0 +00 ( + / -) and H3 +00 ( + / -), near <br />centerline, between stations A0 +00( + / -) and A4 +00 ( + / -), near centerline, and between stations <br />A38 +00( + / -) and A41 +00 ( + / -), near centerline, using a John Deere 35D excavator, a vibratory <br />plate compactor and laborers. An AMEC field representative observed the backfill and it was <br />found to be constructed in accordance with design drawings and project specifications. <br />VLF Weekly Report WE 08.27.2011 <br />
