Perforated and solid HDPE pipe will be utilized to construct the leachate collection <br />and recovery systems. <br /> <br />CQA for the HDPE pipe and tank installations will be performed to verify that HDPE pipe systems <br />and tanks are installed in accordance with the design. Construction must be conducted in accordance <br />with the Construction Drawings and Specifications. To monitor compliance, the CQA program will <br />(1) review the Contractor’s quality control submittals; (2) monitor construction testing; and (3) <br />monitor installations. <br /> <br />All construction testing will be conducted in accordance with the Specifications. <br /> <br />5.2 Construction Monitoring <br /> <br />The following sections list monitoring requirements during HDPE pipe and tank operations. <br /> <br />5.2.1 Delivery, Handling, and Storage <br /> <br />• Verify that chains, end hooks, cable slings, or any other devices that may scar the pipe <br />or tank are not used for handling. Wide nylon web slings are recommended to handle the <br />pipe. <br /> <br />• Verify that the pipe or tanks are not damaged during handling operations and that <br />damaged pipe or tanks are separated from accepted materials. <br /> <br />• Verify that pipe out-of-roundness will not occur due to excessive stacking heights when <br />the pipe is stored at the site. Recommended stacking heights for pipe are provided in the <br />following chart: <br />
