This project will increase water system reliability by installing a pressure reducing valve (PRV) between two of the City’s pressure zones: Wagner 517 and The Farm 440. This PRV will be located along 199th Avenue SE, near Rainier View Park.
The construction contract provides for the installation of a packaged PRV station, including a precast vault. The fully assembled PRV station will be supplied by the City. The contractor will perform all excavations and subbase preparations, make all final outside connections, and construct other improvements, including ductile iron water main, PVC drain pipe, concrete sidewalk, concrete curb and gutter, HMA pavement patching, property restoration, and other work, all in accordance with the contract documents.
After review and state licensing verification, the lowest responsive bidder is D&G Backhoe, Inc. Engineering staff are working with D&G Backhoe to execute this construction contract and schedule a pre-construction meeting. The pre-construction meeting is expected to occur early December, with construction activities commencing shortly thereafter. The construction window is anticipated to span three weeks, with most work substantially complete by the end of 2020.
