This project exhibits Valentine’s success with the design of booster pump station improvements, the ability to produce an intricate construction sequence plan, unique experience with public involvement, as well as utility coordination in a congested area with unreliable as-builts. Valentine provided engineering design drawings and specifications for booster pump station improvements on a small site in a high-end neighborhood. The design encompassed replacing four existing pumps with four new VFD driven booster pumps for a total pumping capacity of 3,600 gpm. In addition to the pump replacement, yard piping was modified, and upsized, new flow monitoring was added, new PLC panel, new HVAC system and ductwork, lighting, receptacles, and the roof of the pump station building was replaced. It also included the addition of a new manual transfer switch and generator quick connect panel for emergency power, a mini power zone, and pressure indication panel which housed the pressure transmitter and switches that monitored the pump suction and discharge lines. A major part of the design was providing the ability to maintain the pump station in service while replacing the pumps and installing new suction and discharge connections. To relay the sequence of work and available shut down periods to the contractors, a Maintenance of Plant Operation (MOPO) was created for the project work as part of the specifications. A complex bypass system and the MOPO plans were developed to meet the same water demands, noise pollution constraints, emergency backup plans, and small facility footprint limitations. The automated system allowed construction on the new station upgrades to proceed as planned, without interruption to surrounding Paradise Valley residents, a private country club and golf course, and a high-end resort, JW Marriott’s Camelback Inn.
