The Alewife Research Center is a project that transformed an existing three-story office building into a modern, environmentally-conscious research facility with new retail and lab office space. The project required the demolition of the 3rd floor and roof to allow for an additional 160,000 SF of new steel framed construction above the existing second floor. To accomplish the four-story expansion, the existing steel columns were selectively encased with newly reinforced concrete to support new floor layout above. In doing so, nearly all the original foundations were removed and reconstructed. The ARC is located directly across the street from the MBTA Alewife Redline station and bus terminal, a convenient public transit oriented building.
