SECTION 02778 <br /> HIGH DENSITY POLYETHYLENE(HDPE)GEOMEMBRANE <br /> PART GENERAL <br /> 1.1 WORK INCLUDED <br /> A. This section covers the Work necessary to furnish and install 60-mil single-sided and <br /> double-sided textured high density polyethylene (HDPE) geomembrane liner in <br /> WMU FU-13, complete. <br /> B. The GEOSYNTHETICS CONTRACTOR shall furnish all labor,supervision,tools, <br /> equipment,and materials necessary to complete the HDPE geomembrane installation <br /> including,but not limited to,submittals,panel layout,seaming,patching,temporary <br /> anchorage,temporary slip sheeting,and all necessary and incidental items required to <br /> complete the Work in accordance with these Specifications and the Construction <br /> Drawings. The EARTHWORK CONTRACTOR will perform excavation and <br /> backfilling of anchor trenches and will unload the HDPE geomembrane if the <br /> GEOSYNTHETICS CONTRACTOR is not onsite. <br /> C. A leak location test will be performed on the geomembrane before and after <br /> placement of the granular drainage material and protective operations layer. The <br /> GEOSYNTHETICS CONTRACTOR shall be responsible for repairing all identified <br /> leaks in the geomembrane prior to placement of the overlying earthwork and <br /> geosynthetic materials at his sole expense. The EARTHWORK CONTRACTOR <br /> shall be responsible for repairing all identified leaks in the geomembrane following <br /> placement of the overlying earthwork and geosynthetic materials. The <br /> EARTHWORK CONTRACTOR shall remove all earthwork and geosynthetic <br /> materials overlying the geomembrane to the extent required to repair the leak and <br /> shall repair all identified leaks in the geomembrane at his sole expense. Following <br /> the repair of the leak in the geomembrane,the EARTHWORK CONTRACTOR shall <br /> replace all earthwork and geosynthetic materials at his sole expense. All Work <br /> performed to repair and replace materials shall be performed in accordance with the <br /> applicable Specifications sections. <br /> 1.2 REFERENCES <br /> A.
