Description

Site work and new construction of a mixed-use development in San Francisco, California. Completed plans call for site work for a transportation facility; and for the construction of a power facility.

The Airport Substation Transformer Upgrade Project (Project) will replace the two existing Airport Substation transformers with three new 55-MVA transformers (one will serve as a backup), the existing switchgear equipment, and other supporting electrical systems. This contract will increase capacity and improve power supply reliability and redundancy for power supply scenarios outside of normal operations. The Project is one of the two substations that provides power to the Airport, which is a campus operational twenty-four (24) hours a day throughout the year. The Airport shall remain operational at all times during the project's implementation. The Project is also located on the West of Bayshore (WOB) property owned by the Airport. The WOB property contains major utilities, water pump stations, and a biologically sensitive habitat that supports endangered species. The Airport is implementing a long-term Recovery Action Plan for the San Francisco garter snake. Services will need to be implemented in phases, and all the requirements to ensure no disruption to Airport Operations and avoid and minimize impacts to the WOB San Francisco Garter Snake Recovery Action Plan during construction should be applied. Interested firms must contact the CM for document access.
