Body
BACKGROUND & HISTORY:
The Utilities Department (UD) infrastructure division operates and maintains the City of Corona’s extensive underground infrastructure, including approximately 849 miles of water mains (including service laterals), 24,319 system/control valves, and 8,776 fire hydrants.
UD regularly installs watermains to replace aging pipes to improve system reliability and water quality. The department uses both in-house staff and contractors to install mainlines, modify water distribution systems for new developments, and repair ruptured pipelines. In addition, the staff recognizes that pipeline failures can lead to disruptions in the water supply and require road closures and repairs.
The existing 10-inch potable water-main line on Liberty Avenue has experienced failures in the last two years, causing disruptions in service and flooding. The service life of water mains depends on multiple factors such as pipe condition, pH level, abrasion resistance, soil and water resistivity, chloride, sulfate, or acid corrosion, slow crack growth, electrochemical corrosion of steel, and working environment. Native soil conditions, soil compaction, and soil stability can also impact water main degradation. Most of the waterline, which is a cement mortar-lined steel pipe, was originally installed in 1957.
ANALYSIS:
The Plans and Specifications for the Liberty Avenue Waterline Installation Project were completed by KWC Engineers and reviewed and approved by the Corona Public Works Director and the County of Riverside. Additionally, because of the proximity to Metropolitan Water District’s (MWD) Lower Feeder, MWD also reviewed and approved the alignment. As specified in the bid package, the City shall award the Contract for the project to the lowest responsive, responsible bidder as determined from the lowest total for the Bid Schedule.
On January 31, 2024, the Purchasing Division issued a Notice of Inviting Bids (NIB 24-044CA) following City of Corona Municipal Code (CMC) Section 3.08.110, Non-public projects - formal bidding procedure The NIB was posted on the City’s PlanetBids bidding portal. Bid documents were made available to the City’s 14 pre-qualified pipeline contractors. A total of three bids were received from the following prequalified contractors by the March 7, 2024, deadline.
