MSJWTP Tank Decommissioning and Building Systems Modification

The Alameda County Water District is soliciting proposals for engineering consulting services to support the Mission San Jose Water Treatment Plant (MSJWTP) Tank Decommissioning and Building Systems Modification project. The scope of work includes decommissioning the Mission San Jose Treated Water Tank, upgrading fire suppression systems to utilize non-potable water from the South Bay Aqueduct, and modifying the offsite Ohlone Regulator to ensure continued fire suppression flow. Additionally, the consultant will evaluate and upgrade or demolish existing HVAC infrastructure, integrate new controls into the SCADA system, and provide CEQA compliance support and coordination with the Department of Water Resources. Key deliverables include a Basis of Design report and the performance of point-to-point, dry, and wet testing for the building management system. The contract will be awarded to the highest-ranked consultant based on qualifications, staff experience, and the proposed approach to ensure the best value. Compensation is structured on a time and materials basis with a not-to-exceed cost ceiling, with payments issued within 45 calendar days of invoice receipt. Proposals must be submitted electronically via the Bonfire portal by November 17, 2026, and must adhere to strict formatting requirements across two PDF volumes. Notable constraints include a requirement that the tank cannot be taken out of service before March 1, 2027, and the necessity for consultants to provide a DIR registration number and comply with prevailing wage laws.
