Before installing any of the geomembrane, the Geosynthetics Contractor must <br />submit a drawing in accordance with the Specifications. The drawings will show the proposed <br />layout of the panels, including panel identification numbers, field seams, and any details that do not <br />conform to the Construction Drawings. <br /> <br />The QA/QC Inspectors will maintain an up to date panel layout drawing that shows the following: <br />(i) roll numbers; (ii) panel numbers; (iii) seam numbers; (iv) test locations; (v) repair locations; and, <br />(vi) non-destructive testing information. <br /> <br />During panel placement operations, the QA/QC Inspector will: <br /> <br /> Record panel numbers and dimensions on the panel/seam log. <br /> <br /> Observe the panel surface as it is deployed and record all panel defects and defect <br />corrective actions (panel rejected, patch installed, extrudate placed over the defect, etc.) <br />on the repair sheet. Verify that corrective actions are made in accordance with the <br />Specifications. <br /> <br /> Verify that equipment used during deployment operations does not damage the <br />geomembrane. Verify that equipment used on the geomembrane does not leak <br />hydrocarbons onto the geomembrane or that corrective measures are taken to prevent <br />leakage. <br /> <br /> Verify that the surface beneath the geomembrane has not deteriorated since previous <br />acceptance. Verify that no stones, construction debris, or other items are beneath the <br />geomembrane that could damage the geomembrane. <br /> <br /> Verify that the geomembrane is not dragged across an unprotected surface. If the <br />geomembrane is dragged across an unprotected surface, the geomembrane must be <br />inspected for scratches and repaired or rejected, if necessary. <br /> <br /> Record weather conditions including temperature, approximate wind speed and direction, <br />and approximate humidity. Verify that the geomembrane is not deployed in the presence <br />of excess moisture (fog, dew, mist, etc.). In addition, verify that the geomembrane is not <br />placed when the air temperature is less than 400F, or when standing water or frost is on <br />the ground. <br /> <br /> Verify that crews working on the geomembrane do not smoke, wear shoes that could <br />damage the liner, or engage in activities that could damage the geomembrane. <br />
