Utilities Department Plumbing Services

The City of Corona Utilities Department is soliciting competitive proposals under RFP No. 27-010SB for on-call plumbing services, with proposals due electronically through the PlanetBids Vendor Portal by 10:00 a.m. on December 8, 2026. Written questions are due by 5:00 p.m. on November 12, 2026. The source names no set-aside, preference, or pre-bid meeting.

Contractors must hold a C-36 Plumbing Contractor license, comply with California prevailing wage requirements, and register with the California Department of Industrial Relations. They must also provide Certificates of Reported Compliance demonstrating adherence to CARB In-Use Off-Road Diesel-Fueled Fleets Regulations, and obtain a City of Corona Business License before contract award. The selected contractor must maintain at least four field plumbers available to the City and provide 24/7 service, with one-hour response for emergency calls and 24-hour response for non-emergency calls.

Work is as-needed and includes general plumbing repairs, maintenance, installation, and replacement, plus drain and sewer cleaning, video and jetting, leak detection, copper sweating, trenchless line repair, natural gas piping, polypropylene fusing, and regulator installations. Contractors furnish all labor, materials, equipment, and mobilization. The contract provides no guaranteed usage.

Pricing is structured as hourly rate schedules for straight time, overtime, holidays, and emergency services across master plumbers, journeymen, and apprentices. Materials are billed at contractor cost plus 15 percent. The City does not reimburse travel time, mileage, or service charges, and only on-site labor hours are compensable. Payment bonds at 100 percent are required for individual call-out projects exceeding $25,000, and performance bonds may be required as indicated in project work orders. Insurance requirements are comprehensive general liability of $3 million per occurrence and $6 million aggregate, automobile liability of $1 million, and workers' compensation of $1 million.

The initial term runs from February 3, 2027 through June 30, 2028, with two optional two-year renewals extending to June 30, 2032. Option-year pricing adjusts by the Consumer Price Index for Riverside, California, not to exceed the percentage change in the index. The City anticipates contractor selection on January 4, 2027, Notice to Proceed on January 17, 2027, and City Council approval and contract award on February 3, 2027.
