November 17, 2017

The MBTA Green Line Extension project team today held a "price opening" to select the design-build firm that will perform the design and construction for the Green Line Extension.

The winning team is a Joint Venture of GLX Constructors, with a total contract price offering of $1,082,118,600. The bid includes all six additive options and MBTA contingency. The inclusion of prioritized additive options means that in addition to track infrastructure and seven station stops, construction will include platform canopies, additional elevators at select stations, public art, additional community connection to the community path located on Chester Street in Somerville, extension of the community path between East Somerville and Lechmere Stations and an enhanced vehicle maintenance facility in Somerville.

On Monday, the Fiscal and Management Control Board will be asked to accept staff’s recommendation of GLX Constructors for the total contract price offering.

GLX Constructors is comprised of Fluor Enterprises, Inc., The Middlesex Corp., Herzog Contracting Corp., and Balfour Beatty Infrastructure, Inc.

October - November 2017

On October 17, 2017, the MBTA filed a Notice of Project Change (NPC) for the Green Line Extension Project with the Executive Office of Energy and Environmental Affairs (EEA). This NPC will be published in the November 8, 2017 edition of the Environmental Monitor. A copy of the document can be found on the Project Documents page.

The NPC presents a preliminary proposal for a one-mile extension of the Green Line along the MBTA Lowell Line commuter rail right of way from the currently planned terminus at College Avenue in Medford to Mystic Valley Parkway (Route 16) in Medford and Somerville.
