PART I <br /> PURPOSE <br /> This manual addresses the quality assurance and quality control of the installation of <br /> High Density Polyethylene(HDPE)geomembrane liners used by Colorado Lining <br /> Construction (CLC) in hazardous waste disposal landfills, surface impoundments or other <br /> installations as specified by the owner and/or engineer. This manual delineates the <br /> quality procedures and standards for installation. <br /> 1.1.0 Scope of Quality Assurance <br /> The scope of this manual includes the quality assurance applicable to shipment, handling, <br /> and installation of High Density Polyethylene(HDPE) geomembrane liners also referred <br /> to Flexible Membrane Liners(FML's). <br /> 1.2.0 Units <br /> In this manual, all properties and dimensions are expressed in English units,with <br /> "equivalent"Systeme International(SI)/metric units in parentheses. It should be noted <br /> that the conversion is typically only accurate within ten percent. In cases of conflict or <br /> clarifications,the U.S. units shall be deemed to govern. Since most field geomembrane <br /> testing equipment manufactured in the United States are equipped to measure in English <br /> units, required test result data are tabulated herein with such units. <br /> 1.3.0 References <br /> The manual includes references to test procedures of the American Society for Testing <br /> and Materials(ASTM), the Federal Test Method Standards(FTMS)and the"Standards for <br /> Flexible Membrane Liners"of the National Sanitation Foundation (NSF). <br /> PART II <br /> DELIVERY <br /> 2.1.0 Transportation and Handling <br /> CLC through its own transportation or an independent trucking firm or other party as <br /> agreed upon by the Owner will perform transportation of the geomembrane. If the <br /> geomembrane arrives on site prior to CLC project personnel, the Owner is responsible for <br /> off-loading roll goods and any ancillary items shipped. The material received shall be <br /> matched against the freight bill of lading. Any discrepancies shall be immediately <br /> reported to CLC before the shipment is signed for. When off-loaded, geomembrane and <br /> any ancillary items should be placed on a smooth, well drained surface, free of rocks or <br /> any other protrusions which may damage the material. No special covering is necessary <br /> for geomembrane. <br /> The following should be verified prior to and during off-loading geomembrane: <br /> Handling equipment used on the site is adequate and does not pose any risk or <br /> damage to the geomembrane and that personnel handle the geomembrane with <br /> care. If slings are provided, the material should be lifted with such. In any <br /> event, materials shall be offloaded in a safe manner whereby the rolls are <br /> properly balanced and no personnel or property are at risk of being <br /> injured/damaged should loss of control of any roll(s)of material occur. <br /> Upon arrival at the site, CLC shall conduct a surface observation of all rolls for <br /> Created by Colorado Lining International 1-800-524-8672 2 <br />
