A joint venture (JV) led by Aecom Technology has secured a $43.3m contract from the Massachusetts Department of Transportation to carry out advanced preliminary design services for the first phase of the Massachusetts Bay Transportation Authority’s (MBTA) Green Line light rail extension in Boston, US.

Under the deal, the JV will also offer final design services as well as services during construction in future phases of the contract for several elements.

The JV will provide services for the construction of seven new stations and 4.5 miles of light rail track, the relocation of Lechmere station, the reconstruction of bridges along the corridor and the development of a new maintenance and transportation facility.

Aecom chairman and chief executive officer John Dionisio said: "Our local light rail expertise, as well as our direct experience with the entire MBTA system, position Aecom well to help improve Green Line service for Boston’s residents and visitors."

The Green Line Extension (GLX) project will extend the light rail service from the relocated Lechmere Station in East Cambridge to Union Square in Somerville and College Avenue in Medford.

After the completion of the line, trains will run every five to six minutes during peak hours to offer faster transport to downtown Boston.

In February 2011, the MBTA awarded a contract to the HDR/Gilbane Team to oversee the GLX project.

The firm, a joint venture of HDR Engineering and Gilbane Building Company, is responsible for programme management, construction management and the preliminary design of the project.
