Liberty Mutual Office Expansion   Boston, Massachusetts

The 22 story, 590,000SF building at 157 Berkeley Street, Boston is an expansion of Liberty Mutual's Back Bay Campus. The new structure is combined with an existing 10 story structure that houses the high end steak house, Grill 23, on the lower floors.

The restaurant remained open during the construction of the new tower creating unique and challenging logistical issues that had to be overcome. In addition, the building was the first project in Boston to incorporate a smoke removal system required by the 8th Edition of the Massachusetts State Building Code.
