5 CONSTRUCTION QUALITY ASSURANCE FOR HDPE <br /> PIPE <br /> 5.1 Introduction <br /> This section describes CQA procedures for high density polyethylene (HDPE) pipe installations. <br /> Perforated and solid HDPE pipe will be utilized to construct the leachate collection and recovery <br /> systems. <br /> CQA for the HDPE pipe installations will be performed to verify that HDPE pipe systems are <br /> installed in accordance with the design. Construction must be conducted in accordance with the <br /> Construction Drawings and Specifications. To monitor compliance, the CQA program will (1) <br /> review the Contractor's quality control submittals;(2)monitor construction testing;and(3)monitor <br /> installations. <br /> All construction testing will be conducted in accordance with the Specifications. <br /> 5.2 Construction Monitoring <br /> The following sections list monitoring requirements during HDPE pipe operations. <br /> 5.2.1 Delivery, Handling, and Storage <br /> • Verify that chains end hooks cable slings,or any other devices that may scar the pipe are <br /> not used to handlepy iP e. Widen nylon web slings are recommended to handle the pipe. <br /> • Verify that the pipe is not damaged during handling operations and that damaged pipe is <br /> separated from accepted pipe. <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 /> Page 46 <br />
