WMU FU-06 November 2006 <br /> Forward Landfill Project No.021605.07 <br /> ® Field Panel Placement: During the panel placement, Vector's CQA Monitor kept <br /> panel deployment logs. These logs recorded the location (panel number and roll <br /> number), installation schedule (date and time), weather conditions (temperature <br /> and wind), and thickness of the sheet. Designation of double sided textured <br /> geomembrane was assigned a prefix of "T" and the single sided geomembrane was <br /> assigned a prefix of "P". These panel deployment logs are presented within <br /> Appendix I. <br /> 5.3.2.2 Field Seaming <br /> Seam Layout: Vector's CQA Monitor documented that the seam numbering system <br /> is compatible with the panel numbering system. A seam numbering system was <br /> assigned by using both panel numbers separated with a dash (i.e.: as in 3/4 is the <br /> seam of panel 3 and panel 4) <br /> Seaming Equipment and Products: Vector's CQA Monitor observed that the <br /> ® seaming equipment used by the subcontractor was in accordance with the project <br /> specifications. In addition, Vector observed that the extrudate (welding rod) used <br /> was compatible with the geomembrane material and was comprised of the same <br /> resin as the geomembrane. <br /> The liner crews seamed the HDPE geomembrane panels using double wedge and <br /> extrusion welding techniques. The majority of seams were joined using double <br /> wedge welders, with difficult geometry and repairs made using extrusion welders. <br /> Vector's CQA Monitor observed the seaming activities and observed for proper panel <br /> overlap, cleanliness of the seams, grinding where required, and speed and <br /> temperatures of the equipment used. Documentation of the activities was recorded <br /> on the geomembrane seaming log, which includes information on the seam number, <br /> Vector Engineering, Inc. • 143E Spring Hill Drive• Grass Valley, CA 95945•(530)272-2448 <br /> -27- <br />
