October 2001 -28- 003-2182.004 <br /> 6.1.3.2 Seaming Observations <br /> Golder personnel observed seams before, during and after welding. Golder checked each seam <br /> for adequate overlap prior to seaming and to verify that the seam area was clean and dry. <br /> Golder brought any concerns to the attention of Poly-Flex. <br /> Golder documented Poly-Flex personnel performing the seaming and the seaming equipment <br /> used. Following the completion of seaming and routine repairs, Golder checked the full length <br /> of each seam to verify that no additional repairs were required. In the event that additional <br /> repairs were needed, Golder marked the location needing repair on the geomembrane, <br /> documented the location, and brought the repair area to the attention of Poly-Flex. Once Poly- <br /> Flex made repairs, Golder checked the repair location to verify completion. Golder inspected <br /> all seams for quality and completion. Golder personnel conducted a final walk-through to <br /> verify completion of the entire geomembrane system and to identify any additional damage that <br /> may have occurred during construction operations. No additional damage was identified after <br /> initial construction. <br /> Golder recorded observations made during seaming. The fusion welding summary is presented <br /> in Appendix J-5a and J-5b, and the extrusion welding summary is presented in Appendix J-6a <br /> and J-6b. <br /> 6.1.4 Defect and Repair Observations <br /> Golder inspected geomembrane panels for damage that may have occurred during manufacture, <br /> transport, deployment, or installation as discussed. <br /> Golder documented defects by assigning a unique defect identification code to each defect, and <br /> marking each defect code on the geomembrane.
