TECHNICAL SPECIFICATIONS <br />Protect geomembrane in areas where excessive traffic is expected with geotextiles, extra <br />geomembrane, or other materials acceptable to MANAGER, DESIGN ENGINEER, and <br />CERTIFYING ENGINEER. <br />3.5 FIELD PANEL DEPLOYMENT <br />A. CONTRACTOR shall install field panels at locations indicated on CONTRACTOR'S layout plan, as <br />approved by MANAGER, DESIGN ENGINEER, and CERTIFYING ENGINEER. <br />B. CONTRACTOR shall replace damaged (i.e., torn, twisted, or crimped) field panels, or portions <br />thereof, at no cost to CC &V. CONTRACTOR shall repair less serious damage, at no cost to CC &V. <br />CERTIFYING ENGINEER shall determine if material is to be repaired or replaced. <br />C. CONTRACTOR shall remove damaged panels, portions of damaged panels, and other geomembrane <br />scrap. <br />D. CONTRACTOR shall not deploy more geomembrane field panels in one day than can be seamed <br />during the day of deployment. <br />E. Geomembrane deployment shall proceed between ambient temperatures of fourteen degrees (14° F) <br />Fahrenheit to one - hundred degrees (100 °) Fahrenheit. Geomembrane placement shall not be done <br />during any precipitation, in the presence of excessive moisture (e.g., fog, rain, dew) or in the presence <br />of excessive winds, as determined by the CQA MONITOR. <br />F. Following the installation of the geomembrane, an examination of the entire surface shall be conducted <br />to detect potentially harmful rocks or other objects. Any such objects will be removed and the <br />geomembrane repaired by the CONTRACTOR, at no cost to CC &V. <br />3.6 FACTORY SEAMS <br />A. MANAGER and CERTIFYING ENGINEER may require CONTRACTOR to test up to as much as <br />twenty percent (20 %) of factory fusion welds (non- destructive air pressure test) in the field to verify <br />factory test results. Additional testing at CONTRACTOR'S expense will be required if failed tests are <br />obtained in the field. <br />3.7 FIELD SEAMS <br />A. Seam Layout <br />Seams shall be oriented parallel to the line of maximum slope, i.e., oriented down, not across the <br />slope. In corners and odd - shaped geometric locations, the number of field seams shall be <br />minimized. <br />No horizontal or base T -seam or tie -in seams shall be closer than five (5) feet from the toe of the <br />slope. Seams shall be aligned to prevent wrinkles and "fish mouths." If a fish mouth or wrinkle is <br />found, it shall be relieved and capped. <br />Panels of geomembrane will have sufficient overlap provided to allow peel tests to be performed <br />on the seam. <br />B. Seaming Method <br />The procedure used to temporarily bond adjacent panels together shall not damage the <br />geomembrane; in particular, the temperature of hot air at the nozzle of any spot welding apparatus <br />shall be controlled such that the geomembrane is not damaged. <br />CONTRACTOR shall use double fusion welding as primary method of seaming adjacent field <br />panels. <br />Geomembrane August 28, 2013 <br />02776.1 -10 Revision 0 <br />S \Projects \1550 - CC &V Field Spt CQA PSES Bldg \8 0 Project Engineering and Design \8 2 Specificabons\PSES Pipe Rack Liner Extension Specifications \02776 I Ckomembrane docx <br />
