SGH has provided building enclosure and structural engineering consulting services for multiple projects, including the Mall Terrace rehabilitation as part of a task order contract for the Pentagon. The historic Mall Terrace, on the building’s north side, comprises three monumental stone stairs, several sunken planters, and a large asphalt parking lot with perimeter concrete sidewalks. Most of the terrace structure is part of the original building constructed in 1942. Despite past repair attempts, the occupied areas below suffered from water infiltration and damage to the existing structure. SGH investigated the sources of leakage and designed repairs for the Mall Terrace.
