11 <br />nonconformant with the Specifications, and corrective measures shall be <br />implemented. Corrective measures shall include a rerun of the conformance <br />testing using a portion of the same sample. If the second test passes, the <br />Geotechnical CQA Officer may assume an error was made in the first test and the <br />geotextile material can be accepted. If the second test fails, the Contractor/Liner <br />Subcontractor shall remove all material represented by the sample from the work <br />area. The decision of the Construction Manager shall be final. <br />6.1.3 GEOCOMPOSITE INSTALLATION <br />6.1.3.1 Surface Preparation <br />Prior to installation, the Construction Manager and Geotechnical CQA Monitors <br />shall observe that: <br />• All lines and grades have been verified. <br />• The subgrade has been prepare din accordance with the Project Specifications <br />and the supporting surface does not contain rocks or irregular surfaces which <br />could damage the geocomposite. <br />• There are no excessively soft areas, which could result in damage to the <br />geocomposite. <br />• All construction stakes and hubs have been removed. <br />• The Contractor/Liner Subcontractor has certified in writing that the surface on <br />which the geocomposite will be installed is acceptable. <br />6.1.3.2 Placement <br />The Contractor/Subcontractor shall give each geocomposite panel an <br />identification number, which shall -be agreed to and usedby the Geotecimicai <br />CQA Monitors and the Contractor/Liner Subcontractor. The Geotechnical CQA <br />Monitor shall establish a chart showing correspondence between rollwnumbers, <br />certification reports, and panel numbers. <br />During panel placement, the Geotechnical CQA Monitor shall: <br />• Observe the geocomposite as it is placed and record all defects and disposition <br />of the defects (panel rejected, patch installed, etc.). All repairs are to be made <br />in accordance with the Specifications. <br />• Observe that equipment used does not damage the geocomposite by handling, <br />traffic, leakage of hydrocarbons, or other means. <br />• Observe that people working during installation of geocomposite do not <br />smoke, wear shoes that could damage the geocomposite, or engage in other <br />activities that could damage the geocomposite. <br />Observe that the geocomposite is anchored to prevent movement by the wind. <br />C\2001-048\EINAL COVER_CQA.DOC\08/20/01 <br />-15- <br />Geologic Associates <br />
