16th Street Pump Station Upgrades and Back-up Generator — Notice of Completion for Contract No. 7693-2 (18W13)
September 24, 2024
This project included the removal of three solid state soft starters; replacement of three vertical turbine pumps and five pump motors; and the installation of new control valves, three new variable frequency drives (VFD), three slanted check valves, an automatic transfer switch, and a 1,000-kW diesel back-up generator with a 4,000-gallon diesel storage tank. The new pumps, motors and VFDs are more reliable and energy efficient than the previous components and will improve the City of Newport Beach's water system.
A change order was issued to complete the first phase of the Collins Island sewer lift station upgrade to expedite the completion of the final electrical panel location created by an opportunity to coordinate with a new home construction project. The new electrical panel is located in a cabinet structure that matches the architecture of the home it is attached to. The contractor has excellent experience constructing sewer lift stations, electrical panels and duct bank work, and due to the homeowner's schedule to complete his home, the City had a tight window of opportunity to complete the work, so it made sense to add this electrical work. Funding for this change order work was expended from the Wastewater Capital fund.
The contracted work has been completed to the satisfaction of the Public Works Department. A summary of the contract construction costs are as follows:
