The Arlington/Copley Station Rehabilitation Project involved the renovation of two MBTA stations to allow handicap accessibility to the Greenline. The work included the installation of five new elevators, three new escalators, demolition and reconstruction of station platforms, system upgrades and station improvements.

All work was performed while both stations remained in service for revenue passengers. coordination with MBTA Greenline operations and the City of Boston was key to maintaining continued unobstructed access to these stations

The earthwork included jet grouting, mini-piles, drilled shafts and soldier beams with lagging. concrete elements included both structural and architectural concrete. Utilities, surface restoration, lighting and station enhancements were also completed.

A significant aspect to this project was the close proximity of the work to national historic landmarks such as the Boston Public Library, Old South Church and the Arlington St. Church.

One highlight of the renovations was the restoration of the nearly 100 year old historic head house structure to its turn of the century beauty.

Contract value: $49,000,000.
