MBTA Green Line Extension Project

Arora was part of the AECOM/HNTB Joint Venture (A|H JV) design team responsible for mechanical, electrical, plumbing, fire protection and fire alarm design development for the Green Line Extension Project’s advanced conceptual design through complete design of the original concepts for the new stations and VMF. As the project shifted to design-build delivery, Arora and the A|H JV assisted the MBTA with development of the design-build procurement documents. Following the award of the design-build contract, Arora then continued on supporting GLX as part of the MBTA’s Program Management Team led by Arup.

An initiative of the Massachusetts Department of Transportation and the Massachusetts Bay Transportation Authority, the project extends the existing Green Line service from a relocated Lechmere Station in East Cambridge to Union Square in Somerville, and College Avenue in Medford.

Design for the project included seven stations, nearly five miles of Green Line double track, the relocation of four miles of double track commuter rail, eight bridges and a vehicle maintenance storage facility.
