Boston City Hall
Location: Boston, Massachusetts
Year Built: 1968
Original Architect: Kallmann McKinnell & Knowles
Boston City Hall was designed by Kallmann, McKinnell, and Knowles as part of a nation-wide competition. It is internationally recognized as a masterwork of 1960s modernism and civic design. Boston City Hall has been the seat of municipal government in the City of Boston since the building opened to the public in February 1969.
BCA completed Boston City Hall’s Conservation Management Plan (CMP), a five-year effort that addresses the preservation and maintenance of this iconic landmark. The CMP was funded as part of the Getty Foundation’s Keeping it Modern grant. The international grant initiative focuses on important buildings of the twentieth century. The CMP provides a historic overview, assessment of significance, identifies issues and opportunities, and developed conservation policies for managing the building into the future.
As part of the CMP, BCA developed cleaning methodologies for the interior concrete surface. Care was taken to identify methods that would remove surface soiling without removing the underlying patina that developed. Methods were identified that could be implemented by maintenance personnel without damaging the concrete.
In 2023 the project received a Preservation Achievement Award by the Boston Preservation Alliance.
