The historic Mall Terrace is located on the Pentagon’s north side and comprises three monumental stone stairs, several sunken planters, and a large asphalt parking lot with concrete sidewalks at its perimeter. Most of the Mall Terrace’s structure is part of the original building constructed in 1942. Despite past repair attempts, the occupied areas below the Mall Terrace suffered from water leaking into the occupied interior space and damaging the existing structure. SGH investigated the sources of leakage and designed repairs.
