Improvements

Improvements will include new redundant elevators from the surface to the Green Line level as well as from the Green Line level to the Blue Line level, renovations to both the Green Line and Blue Line platforms, a new station entrance and lobbies, a new emergency exit-only structure on Cambridge Street between Court and Sudbury Streets, improved circulation between the Green Line and Blue Line platforms, and reconstruction of Cambridge Street and a portion of City Hall Plaza in the vicinity of the Station to provide accessible paths of travel to the station. The project will also upgrade the Station to comply with all current applicable code requirements

Other necessary upgrades include: new escalators, LED signage, a new and expanded fare collection area, upgraded back-up electrical power supply, improved interior finishes, new station lighting, mechanical systems, public address system, and a new emergency exit structure on Cambridge Street. Additional vendor retail space will be provided on both Green Line and Blue Line platforms. A security protection and monitoring system will be installed throughout the Station.

Design and Construction Details

Value Engineering (VE), managed by the Owner′s Representative as required by MGL 30/39M.5, was performed in January 2011. The major recommendation of the study was to close Government Center Station to patrons (but allow trains to pass through) for twenty-four months during the construction period by diverting passengers to other nearby stations. Closure/bypass of the station to patrons for twenty-four months during construction eliminates the need for a temporary head house and allows construction to proceed more rapidly, thereby resulting in the overall delivery of accessibility to be achieved earlier. The closure also results in minimization of system delays, improved worker and public safety, and improved construction quality. The recommendation was presented to the MBTA Board of Directors in April 2011. The Board concurred with that recommendation, and design progressed based on the Station being closed as recommended.

The design and the construction staging of the project has been closely coordinated with City of Boston departments, Mass Historic, federal agencies, project abutters, area business groups, and all major departments within the MBTA. Public presentations of the project have taken place at six area locations. (See meeting notifications on the MBTA Public Meetings page.)
