amee <br />IV)VLF Geosynthetics <br />A) Geomembrane Installation <br />1) VLF <br />Geomembrane installation within the Phase 5 VLF resumed performing deployment, seaming, <br />and repair /QC activities. Geomembrane installation was performed in the area shown in Figure <br />3. Approximately 75,815 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 4,849 linear feet of seam was fusion welded using <br />two fusion welding machine. Ten destructive test samples were marked during fusion seaming. <br />All 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 />During the Cresson blasts, an AMEC field representative observed the geomembrane and no <br />damage was found. <br />B) Geomembrane Exposure <br />1) VLF <br />Exposure of previously installed geomembrane between stations E9 +00 ( + / -) and E11 +50 ( + / -) <br />was performed using a John Deere 35D excavator and laborers. An AMEC field representative <br />observed the geomembrane exposure constantly. <br />C) Anchor Trench <br />1) VLF <br />Temporary anchor trench excavation continued between stations J7 +50 ( + / -) and J9 +00 ( + / -) <br />using a John Deere 35D excavator and one laborer. The anchor trench was inspected by an <br />AMEC field representative and found to be constructed in accordance with design drawings <br />and project specifications. <br />D) Geomembrane Acceptance <br />1) VLF <br />Primary 80mil geomembrane (P -439 & P -476, P -478) shown on Figure 4 was inspected by <br />AMEC and Lonestar representatives and found to be installed within project specifications and <br />acceptable for continued construction activities. <br />E) Geomembrane Delivery <br />1) VLF <br />All geomembrane scheduled to be delivered to site has been delivered and is complete for the <br />Phase 5 VLF project. <br />VLF Weekly Report WE 07.09.2011 <br />
