Architecture
The Central Shared Use Main Buildings is located in the middle of the FDA’s White Oak’s Campus. The main entrance is located on a convex façade which faces the other buildings around it. The main entrance opens into the main lobby on the first floor. There is no ceiling to the lobby, which allows the view of the 2nd and 3rd floors. The lobby connects to a gym on the first floor. The gym includes locker rooms, an aerobic center, cardio room, and free weight room. There is also a kitchen and dining area on the opposite side of the building. The 2nd floor houses some offices, training rooms, an auditorium, video conference room, and library. The 2nd floor is connected to 2 surrounding buildings on the north and south side by 2 bridges. One building is already there, another is a future planned site. The third floor is an open shell. The ground floor consists of offices, conference areas, a command center, and storage. It is connected by a service tunnel to an existing building, and there are future tunnels planned as future buildings are built.
Building Envelope
The front face of the building (the face where the main entrance is located) is glass and aluminum curtain wall. Most of the front face is glass, so stair sections and column sections can be seen through the façade. A film visor sits atop the whole front face of the building. The main entrance consists of two double glass doors with a canopy overhead.
The back and sides of the building is mostly copper siding. Where the main entrance is on the front, there are two doors on the back; one on the first floor, and one on the second floor. There is also a stairway leading down from the 2nd floor to the ground; covered by a metal roof. This section sticks out because it is a temporary wall assembly. The surrounding building will be built into this building in the future, and this section of wall is where the connection will be made. The rest of the wall is copper siding. There is a copper parapet above the temporary wall that goes around the entire building.
The sides of the buildings each have a door entrance at the ground level with another story of glass above. On the third floor above these doors, is an open hole shaped like a window. There are glass guardrails that reach up about 4 feet from the bottom of the hole. Throughout the copper siding, there are rectangular glass windows on the first, second, and third floor. The windows are taller than they are wide, and vary in width.
The roof of the building is a concrete slab with a green roof system on top. There are concrete slab paths that lead around the edge of the roof The center of the roof is taken up by a giant skylight that goes all the way down to the first floor lobby. Two mechanical curbs surround the backside of the skylight. Farther from the skylight on each side, there are two more sections for mechanical equipment, surrounded by an aluminum clad concrete wall.
Construction
The Shared Use Facility is being built now and expected to go until 2006. The site has limited capacity because of surrounding buildings on the campus. The facility is also being connected by bridges and tunnels to the surrounding buildings.
Electrical
The power distribution is both 480/277V and 208/120V. Power is generated by natural gas turbines located in a Central Utility Plant on site. A small portion of the power is generated from solar energy. Future expansion of this solar system is planned. PEPCO is supplying backup power to the building, which will be used for emergancy power.
Lighting
The lighting in the building is mostly florescent. The open areas are lighted by recessed lights, while the office areas are lit by florescent panels. Emergency lighting is provided throughout the building.
Mechanical
There are two Air Handling Units located on the roof. There are also 4 exhaust ducts that tie into an exhaust plenum. VAV boxes are used throughout the building to vary flow and control the temp/humidity. The open areas like the dining and gym spaces have ductwork and vents along the upper wall. The smaller areas have diffusers in the ceiling grid. Each floor has a mechanical room where chilled and hot water are supplied to the floor from underground tunnels. The mechanical rooms are surrounded by double walls with an air layer and also covered in acoustical tile to keep the sound down. Exhaust air is allowed up into the ceiling plenum and then sent to the roof. Special plenum smoke detectors are installed in the exhaust plenums. The amount of air supplied to the areas is dependant on the occupant level, or the size of the area, whichever requires more.
Structural
The building has many structural elements. The tunnels are encased in reinforced concrete. A concrete slab is the floor of the tunnels. The back stairway sits atop grade beams for support.
The building itself has a main structural system of concrete slabs held by rectangular and circular columns. The footings are spread footings that circumference the concrete slab. The slabs are post tensioned.
Fire Protection
The Shared Use Facility is fully sprinkled. The structural frame is has a 2 hour fire rating. If an interior column is not supporting a roof, it only has a 1 hour fire rating. The bearing exterior walls have 2 hour fire protection, as do the bearing interior walls. Nonbearing walls are rated for 1 hour if on the exterior and dependant on the occupancy elsewhere. All of the floors have a 2 hour fire rating. The roof is rated for 1 hour. The corridor walls along egress routes that are fully sprinkled do not have any fire rating.
Telecommunications
The offices and conference rooms are all equipped with phone and Ethernet jacks.
Transportation
There are 2 stairwells located at the sides of the buildings, and 2 elevators in the back of the lobby. For the business occupancy, the longest distance of egress traveled is 91 meters. The common path of travel is only 30 meters. For assembly occupancy, 60 meters is the longest distance traveled.
Special Systems
The Shared Use facility has a security system with the main security office located on the first floor.
