<br /> Page 37 <br />5 CONSTRUCTION QUALITY ASSURANCE FOR HDPE <br />PIPE <br />5.1 Introduction <br /> <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 pan lysimeter and stormwater <br />features. <br /> <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 /> <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 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 pipes <br />are not used for handling. Wide nylon web slings are recommended to handle the pipe. <br /> <br /> Verify that the pipes are not damaged during handling operations and that damaged pipe <br />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 />
