San Joaquin Reservoir Valve Actuator Replacement

The project involves the removal and replacement of five valve actuators on the San Joaquin Reservoir outlet pipeline, including three 48-inch, one 24-inch, and one 60-inch units, with two located above the typical low waterline and three below, necessitating diving operations. The contractor is responsible for replacing all associated hydraulic lines, ball valves, and seapots, as well as in-kind replacement of solenoid valves, flow control valves, and ball valves within the existing valve control cabinet. The Irvine Ranch Water District will supply the new actuators and seapots. Work must comply with stringent technical specifications, including EN ISO 80079-36, EN ISO 80079-37:2016, and EN 1127-1:2019 for hazardous zone equipment, along with adherence to 49CFR, IMDG, ICAO/IATA, MARPOL, and TSCA regulations for transport and safety. Performance is constrained by seasonal reservoir water levels, with specific accessibility windows for actuators at EL 445 and EL 410, requiring precise scheduling. All work must be performed on-site, with inspections conducted prior to concealment and final acceptance governed solely by the District after corrective action of deficiencies. The contract follows a Lowest Price Technically Acceptable (LPTA) award method, selecting the lowest responsive and responsible bidder without qualitative trade-offs. Bidders must hold a valid California contractor license, comply with California Labor Code provisions, maintain a certified safety program, and submit a non-collusion declaration. Bid security must be physically delivered as a sealed instrument, while all other proposals are submitted electronically via PlanetBids. The District does not furnish a formal list of attachments, nor does it specify federal accounting codes, electronic invoicing systems, or COR/COTR designations. Key personnel must include an on-site health and safety professional, and contractors must provide certificates regarding the use of off-road diesel equipment, with affirmative responses triggering CARB compliance documentation. Delivery of District-furnished materials occurs at the Michelson Water Recycling Plant Warehouse, with risk transferring to the contractor upon unloading at the site. No contract value is specified, as pricing fields remain as placeholders, and all award decisions are based on compliance and lowest price.
