This building is a 2-level, square, underground facility constructed of concrete and steel designed in a 'Cold War Defense Structure' style of architecture. Its lower level is completely below ground, and its upper level is partially below ground, with earthen bermed walls and three feet of earth fill covering its roof. All that can be seen of the structure from the exterior include its concrete entrances, mechanical equipment, a few pipes, and antennae which rise from the large grassed mound (DFC Architectural Inventory, 1996). The east, main entrance is a concrete 5 x 2 bay square, set into the east elevation of the mound. It has a central, double aluminum-frame door which is flanked on each side by fixed-pane, aluminum-sash windows. The north and south elevations of the entrance each have two fixed-pane window bays. The roof of the entrance is flat, composed of reinforced concrete. A concrete overhanging eave above the doors and windows is supported by triangular pilasters which separate the window bays.
Upon entering the building's lobby and immediately to the north, is a set of doors which leads to a tunnel connecting Building 710 with Building 710A. This tunnel is not original and was constructed in 1985, along with Building 710-A. West of these doors, stairs lead down to a large steel vault door, directly entering into a vestibule on the upper level of the building. The building¿s upper level interior has the appearance of an office building without windows, with a large operations room at the center. The lower level originally housed male and female dormitories, medical facility rooms, and still houses mechanical systems, storage, offices, restrooms, lunchroom, and kitchen. Circulation halls have maintained their original configuration on both levels, including stairs wells at both entrance vestibules and a freight elevator at the west entrance vestibule.
The west service entrance was originally an open concrete structure. It has maintained most of its original configuration, but has been enclosed with concrete masonry units, glass block, pedestrian doors, and garage door. A long concrete tunnel leads to a large steel vault door, directly entering into a vestibule on the upper level of the building.
The surrounding site of Building 710's earthen mound includes a circular concrete cooling tower, several antennae, an entry sign, and original landscape light fixtures near the east entry. The east entry has landscaped areas, including a picnic area just off the main entrance. Asphalt paving and parking is located just east of the landscaped area.
