Ten Post Office Square is a thirteen-story, steel-framed structure with a transitional masonry facade. The building, constructed in phases during the 1920s and 1930s, occupies most of a city block. The facade featured a limestone cornice that projected several feet beyond the face and was partially supported by concealed structural steel in the parapet and in stone brackets (modillions) and dentils below the ledge. When a limestone modillion fell onto the public sidewalk, the City of Boston required sidewalk staging protection around the entire building. The building’s owner hired SGH to conduct an emergency facade survey and design repairs.
