Segment A of The West Harris County Regional Water Authority (WHCRWA) Surface Water Supply Project (SWSP) consists of 11 miles of 96-inch diameter water line installed via a combination of tunnels and open cut construction. Overseeing this large project required a large construction management and inspection team to inspect construction work in the field to ensure compliance with the contract and to simultaneously document and track large amounts of information.
We will cover the procedures and protocols setup in place from the beginning that ensured project success. Examples include a clear and defined schedule of values, adherence to the chain of command, and constant field presence of all levels of management to be able to quickly identify and resolve problems before they exacerbate. We have automated geotechnical instrumentation to provide real time settlement alerts from tunneling operations. We take GPS readings of every pipe laid and correlate it to the lay schedule and project drawings and address deviations in alignment. All pipe joints are welded and inspected and reported. All of this information is tracked and stored in the program’s project information system and any necessary information is able to be quickly retrieved.
