Request for Bids (RFB) - DERWA UV Channel Rehabilitation (CIP 26-R023)

The Dublin San Ramon Services District (DSRSD) has issued a Request for Bids (RFB) for the DERWA UV Channel Rehabilitation project (CIP 26-R023) located in Pleasanton, California. The project seeks a qualified contractor to rehabilitate two parallel ultraviolet (UV) disinfection channels within the district's recycled water treatment plant. Specific work requirements include comprehensive surface cleaning, concrete priming, application of leveling compound, and installation of chemical-resistant protective coating to mitigate future damage and erosion. Bidders must possess a valid Class A or Class C-33 Contractor's license and be registered with the Department of Industrial Relations. Key project dates include a non-mandatory project briefing on October 7, 2025, site visits from October 13-17, 2025, and bid submissions due by October 28, 2025, at 2 p.m. The project will require a complete shutdown of the recycled water production system, with work to be performed during two separate, non-consecutive outage windows in January or February when recycled water demand is lowest.

Contractor qualifications include submitting a detailed project schedule, weather mitigation plan, and system outage request. Bidders must provide various documentation, including a bid form, proposed subcontractors list, non-collusion affidavit, and safety qualification documentation demonstrating an acceptable Workers' Compensation Experience Modification Rate. Liquidated damages are established at $250 per day for failing to complete the work by the specified date. The project is anticipated to be substantially completed by March 15, 2026, with a Notice of Award expected in early November 2025. While specific funding sources and total project budget are not explicitly stated in the document, the procurement appears to be open to all qualified contractors meeting the specified licensing and registration requirements. The project involves rehabilitation of existing infrastructure within Alameda County and requires precise coordination with DSRSD staff to minimize disruption to recycled water production operations.
