The geomembrane record drawings, showing the secondary geomembrane <br />panel layout and destructive testing and the primary geomembrane panel layout and <br />destructive testing, are presented in Record Drawings No. 4 and No. 5 in Appendix A, <br />respectivley. <br />During geomembrane deployment, AMEC measured sheet thickness with a micrometer. <br />AMEC measured sheet thickness at five random locations along one edge of each <br />geomembrane panel. The average thickness specified for the 100-mil geomembrane was <br />100 mils. Project specifications for 100-mil geomembrane required that the average of the <br />five thickness measurements be no less than the 100 mils, and that no individual <br />measurement be less than nominal thickness minus 10 mils (i.e., 90-mil). The thickness <br />monitoring provided by AMEC indicated that all of the panels met or exceeded project <br />• requirements. <br />AMEC personnel measured deployed panel lengths by use of a measuring wheel. <br />Recorded lengths were approximate, and do not reflect any trimming or adjustments made <br />for final placement or anchor trench lengths. <br />AMEC personnel observed the surface of each deployed panel. AMEC logged any <br />penetration defects and marked them on the panel. Section 6.2.4 provides further <br />discussion of repairs. AMEC also observed the overlap of each panel with adjacent panels <br />to verify that sufficient overlap for seaming existed. AMEC logged insufficient panel <br />overlaps as defects and marked them for correction. <br />Ames surveyed all panel intersections and destructive seam sample locations. Using these <br />points, AMEC has provided the secondary and primary geomembrane panel layout record <br />drawings (Record Drawing No. 4 and Record Drawing No. 5), in Appendix A. <br />• <br />AMEC Earth & Environmental, Inc. <br />2000 S.
