Circuit Breaker replacement

The Massachusetts Bay Transportation Authority (MBTA) is seeking proposals for the replacement of 49 medium voltage vacuum circuit breakers at multiple MBTA locations in Suffolk County, Massachusetts. The scope of work includes the design, testing, manufacturing, installation, and training for the new circuit breakers, which must be interchangeable with the existing Federal Pacific DST-II-500 MVA air circuit breakers. Bidders must have at least 10 years of experience maintaining medium voltage switchgear and provide references for similar 15kV switchgear breaker replacement projects. The MBTA will select the lowest priced responsive and responsible bidder. Proposals are due by September 30, 2020, with a contract award expected by September 30, 2020 and a service start date of October 7, 2020.

The MBTA's procurement process includes policies regarding small, minority, women, and disadvantaged business enterprises. While no incumbent contractors are listed, the documents reference a previous bid opening in April 2019, where Circuit Breaker Sales NE submitted the lowest bid. The total budget for this project is not provided, but the pricing form indicates lump sum pricing for the work at each of the 6 MBTA locations, with payment terms of 90% upon substantial completion and 100% upon final acceptance.
