Observe that adjacent panels of geocomposite are overlapped a minimum of <br />18 inches where the fabric is not seamed (welded or sewn). When seamed, a <br />three (3) -inch minimum overlap will be required. <br />The Geotechnical CQA Monitors shall inform both the Contractor/Liner <br />Subcontractor and the Geotechnical CQA Officer if the above minimum <br />conditions are not met. <br />The Contractor/Liner Subcontractor shall provide the Construction Manager with <br />a panel layout plan, and shall update this plan daily as the job proceeds. No <br />geocomposite shall be placed until the panel layout plan has been approved by the <br />Construction Manager. During geocomposite placement, the Geotechnical CQA <br />Monitors shall observe that: <br />• The geocomposite is cut only with an approved cutter, and is not torn or <br />ripped. <br />• Geocomposite seaming equipment meet the Project requirements. <br />• The panels are being overlapped or joined in accordance with the Project <br />Plans and Specifications. <br />• Any damaged roll of geocomposite is removed and replaced. <br />6.2 GEOMEMBRANE (VFPE) <br />Delivery of geomembrane to the site will not be allowed until all required <br />documentation and/or certifications are approved by the CM/Geotechnical CQA <br />Team. It is the responsibility of the Contractor/Subcontractor to ensure that all <br />required documentation and/or certifications are approved prior to shipment. <br />6.2.1 VFPE MANUFACTURING <br />Prior to the delivery of any geosynthetic material, the Liner Manufacturer shall <br />provide the Construction Manager with the following: <br />• A properties sheet for the rolls to be delivered including all specified <br />properties measured using test methods indicated in the specifications. <br />• The sampling procedure and results of testing. <br />• A certification for each roll stating that property values given in the properties <br />sheet are guaranteed by the Liner Manufacturer. <br />• The Geotechnical CQA Officer shall verify that: <br />— The property values certified by the Liner Manufacturer meet the project <br />specifications. <br />— The measurements of properties by the Liner Manufacturer are properly <br />documented and that the test methods used are acceptable. <br />-16- <br />CA2001-048TINAL COVER CQA.DOC\08/20/01 <br />Geologic Associates <br />
