AirTrain Medium Voltage Cable Replacement Phase 1

San Francisco International Airport is soliciting bids for the AirTrain Medium Voltage Cable Replacement Phase 1 project (Contract No. 11837.61), with a virtual pre-bid meeting on November 19, 2026 at 10:00 a.m. Pacific Time and bids due electronically through the Airport's e-Procurement portal by 2:00 p.m. Pacific Time on December 8, 2026. The project carries a Local Business Enterprise (LBE) subcontracting requirement of 5%, which the Contract Management Division (CMD) set because specialized contractors with confined-space and high-voltage cable experience are necessary. Bidders must hold a California Class A or C-10 Contractor's License at the time of bid and be registered with the California Department of Industrial Relations under Labor Code Section 1725.5.

The work replaces one 12-kilovolt circuit from Substation BA to the AirTrain Maintenance Facility and two circuits serving AirTrain substations. Scope includes field investigation, removal and installation of medium voltage cables (500 Kcmil and 4/0 AWG quantities), dewatering of utility tunnels and manholes, cable splicing and terminations, testing, temporary generator provision, and traffic control. Bidders must have completed at least two medium voltage infrastructure projects within the last ten years and two projects in FAA Advisory Circular-compliant airfield environments, and must submit a Safety Prequalification Form. Prevailing wage under California Department of Industrial Relations requirements and San Francisco Administrative Code Chapter 12P minimum compensation apply.

The estimated construction cost ranges from $7.85 million to $9.23 million, and the contract runs 485 consecutive calendar days from the Notice to Proceed. Allowances totaling $640,000 cover contingencies including contaminated water removal, standby time, shift differentials, and duct bank and cable repairs. Bid security is 10% of the total bid amount, and performance and payment bonds are required at 100% of the Contract Sum. Award is subject to Airport Commission approval and Controller certification of fund availability. The jurisdictions listed are San Mateo County and San Francisco City. An optional site visit takes place at 1:00 p.m. on November 19 at Building 674, Level 1, Lobby Area.
