AECOM complete vast extension of Headquarters for the Air National Guard
As a result of the 2005 Base Realignment and Closure (BRAC), key elements of the Air National Guard Headquarters (ANG HQ) currently operating in leased space in Crystal City, Virginia, will be relocated to a new facility at Andrews Air Force Base, Maryland. The new Headquarters and Readiness Center Building (Building 3501) will be an approximately 170,000 sq ft addition to the existing Building 3500 (Conaway Hall) in the northeast portion of Andrews AFB.
The facility will support over 600 personnel and accommodate Audio/Visual, Command Section Delta, Directorate Training Area, and Conference Room Support. Other elements of this project will include site improvements, additional parking, hardscape and landscaping, a memorial park, utilities, communication infrastructure, site stormwater management facilities, and fire protection support.
The design consists of a four-story office wing (Phase 1) with an adjoining two-story conference centre (Phase 2). The two phases will be connected by a three-level atrium that ties back to Conaway Hall on the second level. The ground level connection will be an exterior, open air path, protected by the enclosed second floor connector above. The second floor connector will be a glass-enclosed corridor linking the second floors of both buildings, allowing the anticipated non-secure areas of both buildings to be contiguous.
A formal plaza to the southeast of the building will define the new south entry for the ANG campus. The building façade will use a combination of glass, metal panels and a minimal use of stone and masonry features to create an image that is distinct and substantial, yet harmonious with the surrounding context.
The building is designed with a concrete frame structural system. Phase I follows the stringent requirements and design criteria for progressive collapse to meet Anti-terrorism and Force Protection guidelines. Phase 2 follows standard design practice. Insulated metal panels will be used on part of the west façade, and major portions of the east façade's spandrel panels will be composed of horizontally subdivided sections of flat and ribbed metal panels. Approximately 57% of the overall roof area of the new building will be a vegetated extensive green roof application, ideal for this structure where very minimal maintenance is preferred.
