Approximately 120,586 square feet of 80mi1 LLDPE geomembrane <br />was deployed. Soil Liner Fill was inspected and approved by AMEC, Ames and ECA <br />representatives prior to geomembrane deployment. Approximately 6,033 linear feet of seam was <br />fusion welded during deployment using one or two fusion welding machines for each day of <br />deployment. Approximately 400 linear feet of extrusion welding was completed during this <br />period. Destructive and non-destructive testing was completed in compliance with project <br />technical specifications. <br />Ames continuously excavated anchor trench ahead of geomembrane installation. After <br />geomembrane testing was completed, the anchor trench above finished panels was backfilled <br />and compacted per project specifications. <br />See attached figure for approved geomembrane. <br />
