The Massachusetts Bay Transportation Authority (MBTA) awarded a contract for program management and construction management of the Green Line extension project to the HDR/Gilbane Team, a joint venture of HDR Engineering Inc. and Gilbane Building Co.
The project will extend the Green Line, the nation's oldest light rail line, from the existing Lechmere Station to Medford, Mass.
HDR/Gilbane's role is preliminary design, design management, construction management and overall program management for MBTA.
The total program estimate is just over $950 million, and the extension is anticipated to be completed by 2015.
