RFP: Construction Management Services for the Ultraviolet Disinfection Replacement, District Project 100012 (RE-ISSUE)

Central Contra Costa Sanitary District (Central San) is requesting proposals for construction management services for the Ultraviolet Disinfection Replacement Project at its wastewater treatment plant in Martinez, California, with proposals due November 13, 2026 at 5:00 PM PT via PlanetBids. The original October 2 deadline has been extended; previously submitted proposals may be updated, withdrawn, or retained as submitted and will be reviewed after the new deadline.

The scope encompasses preconstruction services (constructability reviews, cost estimating, scheduling) and construction-phase services (construction management, inspection, and optional safety compliance officer roles) for a 4–5 year construction period beginning mid-2027. The project includes design and construction of new UV buildings, a switchgear building and substation, junction structures, large piping installation, temporary power facilities, and commissioning to meet NPDES requirements. Key team members—construction manager, inspectors, scheduler, cost estimator, and optional safety compliance officer—must meet specific experience and certification requirements. Minimum qualifications include ten years of business experience in wastewater consulting, prior construction management of at least five projects exceeding $25 million, completion of at least two wastewater treatment plant projects within the past five years involving civil, mechanical, electrical, and controls work, and proficiency with Procore. A Northern California office location is desired. Disqualifying factors include evidence of collusion, prior unresolved disputes with Central San, incorrect proposal information, and previous contract defaults.

The anticipated contract value is $7 million for construction management services, with a construction cost estimate ranging from $90 million to $100 million. Compensation will be determined on an hourly rate basis with a firm cost ceiling established during negotiations. The agreement duration is five years. Central San will provide construction trailers, office facilities, utilities, Procore system administration, and electronic document access.

Evaluation criteria are experience in similar projects (25%), Procore proficiency and technical capability (15%), proposed fee and cost-effectiveness (20%), project team qualifications (25%), and references (15%). Central San anticipates selecting the top three scoring firms for interviews in December 2026, with Board consideration of final award in January 2027 and Notice to Proceed expected in February 2027. The consultant questions deadline is November 2, 2026, with responses anticipated by November 6, 2026. Contact Mark Wenslawski with questions.
