RFP: As-Needed Electrical, Instrumentation, and Controls Services in the Capital Improvement Program

The Central Contra Costa Sanitary District (Central San) is soliciting proposals for as-needed professional engineering services specifically focused on Electrical, Instrumentation, and Controls (EI&C) Services to support its Capital Improvement Program. The Request for Proposal (RFP) was released on October 6, 2025, with proposals due by November 4, 2025, through PlanetBids. The district anticipates selecting up to two top-scoring consulting firms, with potential interviews scheduled for November 19, 2025, and a contract award expected in January 2026. The selected firm(s) will provide comprehensive engineering consulting services including condition assessment, design support, construction support, and power system studies on an as-needed basis. Evaluation will be conducted using a 100-point scoring system that assesses responsiveness to the RFP, qualifications and experience, fee schedule, office proximity to Central San, and quality of references. The project requires firms with expertise in electrical engineering services for a wastewater treatment facility that serves nearly 500,000 residents and 15,000 businesses, treating an average of 32 million gallons of wastewater daily.

The contract will span from 2026 to 2030, with Central San reserving the right to contract with up to three firms at its discretion. The total project budget is estimated at $1,500,000 over the four-year period, with compensation structured on a time and materials basis subject to a not-to-exceed ceiling. While no specific set-aside designations for disadvantaged enterprises were explicitly mentioned in the documentation, the RFP suggests a competitive selection process open to qualified electrical engineering consulting firms. The district operates electrical distribution facilities originally constructed in the mid-1970s and subsequently modified, indicating potential requirements for firms experienced with legacy and updated electrical infrastructure. Prospective respondents should be prepared to provide comprehensive engineering services that can adapt to the complex electrical, instrumentation, and control needs of a large wastewater treatment infrastructure.
