the QA/QC Consultant, and replaced by the GCL Manufacturer at no additional cost to the Owner. <br />The Design Engineer shall be contacted to determine additional acceptance testing requirements. <br />4.5.3 GCL Installation <br />The Geosynthetics Contractor will handle all GCLs in such a manner as to ensure that they are not <br />damaged in any way, and will comply with the following. <br />• In the presence of wind, all GCLs will be sufficiently weighted with sandbags to prevent <br />their movement. Such sandbags will be installed during placement and will remain until <br />replaced with the overlying layer. <br />• GCLs will be cut using a utility knife in a manner approved by the QA/QC Inspector. <br />Care should be taken to prevent damage to any underlying liner system components <br />during cutting. <br />• During placement, care will be taken not to entrap stones, or moisture under the GCL. <br />Care will be taken not to drag equipment across the exposed GCL. <br />• Any GCL damaged by stones or other foreign objects, or installation activities will be <br />replaced at no additional cost to the Owner. <br />• The GCL will not be installed on a saturated subgrade or on standing water. The GCL <br />will be installed in a way that prevents hydration of the mat prior to completion of <br />construction of the liner system. <br />• The GCL will not be installed during precipitation or other conditions that may cause <br />hydration of the GCL. <br />• The GCL will be installed with the woven geotextile up, or as otherwise indicated by the <br />GCL Manufacturer or Design Engineer. <br />• Geomembrane installation will immediately follow the GCL installation. All GCL that is <br />placed during a day's work will be covered with geomembrane before the Geosynthetics <br />Contractor leaves the site at the end of the day. <br />• Geomembrane will not be placed on a GCL that is hydrated. <br />• All seams in the geomembrane overlying a GCL will be welded after each geomembrane <br />panel is placed. Heat sealing of the seam alone is not acceptable. <br />• All defects in the geomembrane overlying a GCL and destructive sample locations will <br />be immediately repaired. <br />Page 44 0 <br />
