MBTA seeks firms to design, build Green Line Extension
The Massachusetts Bay Transportation Authority (MBTA) is seeking letters of interest from firms that could provide design and build services for the Green Line Extension.
The move initiates the process for engaging potential bidders in the project's next phase, according to a Massachusetts Department of Transportation (MassDOT) press release.
MBTA will host a forum Nov. 16 to discuss the extension's current scope.
Known as GLX, the project includes the design and construction of two separate branches to serve as an extension to the Green Line: a "mainline" branch that will operate within existing right-of-way of the Lowell Line in Cambridge and Medford, Mass., as well as a branch line operating within existing right-of-way on the Fitchburg Line to Union Square in Somerville, Mass.
The plan includes construction of seven new stations and a vehicle storage and maintenance facility.
The MBTA's Fiscal and Management Control Board on Aug. 8 authorized the agency to draw up procurement documents for selection of a construction team.
The city of Cambridge has signed a memorandum of understanding to contribute $25 million to the project's cost. MassDOT is working to secure $50 million from Somerville.
The project still hinges on the release of $1 billion in federal funds, MassDOT officials said.
Late last year, the MBTA ended contracts with several firms working on the project in an effort to cut cost. In May, the agency's fiscal control board approved a scaled-down version of the extension, which is now estimated to cost $2.3 billion, compared with the project's previous price tag of $3 billion.
