MILLION SQUARE FEET
Project Description: In compliance with the airport master plan, Tier 2 was located south of the existing Midfield Concourse A-B, between future Taxilanes D & E and Taxiways J & Z. To accommodate the flight schedule anticipated by the building tenant (United Airlines), a four-level 2.7 million square feet building was developed with a total of 44 departure gates: 22 wide-body and 22 narrow-body. The overall building width is 142 feet at the center tapering to 110 at the ends.
- Basement Level: Baggage handling system conveyors, airline operations spaces, concessions storage areas, mechanical rooms, & electrical vaults.
- Apron Level: Two airport people mover stations, six separate baggage handling rooms (each room provided with make-up, transfer input and terminating bag delivery systems), baggage tug ramps & drives, airline operations spaces, airport operations spaces (maintenance, public safety, & fire control), 5 loading docks with a total of 12 berths, mechanical rooms & electrical substations.
- Concourse Level: 66 feet wide circulation corridor with 4 moving walkways (2 in each direction), 34-feet deep departure lounges & boarding areas, airline customer service offices, 100,000 SF of concession areas, federal inspections station, and public toilet rooms.
- Mezzanine Level: Sterile corridor for inbound international passengers, federal inspections station primary inspection hall, airline offices, and mechanical rooms.
- Penthouse Level: Two 16,000 SF airline clubs located at the building 1/4 and 3/4 points, one 10,000 SF airline first-class lounge located at the center of the building, and mechanical & electrical rooms.
Transportation Nodes, located at the ¼ and ¾ points along the length of the building, are the primary entry and exit points for passengers connecting to other concourses or the Main Terminal. The nodes are marked by an open, column-free, three-story hall surrounded on the Concourse Level with premium retail space and restaurants. The Sterile Corridor Level above wraps the main hall and a clear span bridge passes through. At the uppermost level, the airline club overlooks the activity below. Each transportation node is topped by a long span truss and sky lights.
Departure Lounges are paired together both laterally and across from one another, at regular intervals, for efficiency and flexibility. Holdroom zones are separated by blocks of retail space, restrooms and other core elements. Each holdroom is 9,300 SF, sized to accommodate two simultaneously departing wide-body jets. At the ends of the building consolidated holdrooms, each 25,800 SF, serve 8-9 closer spaced narrow-body gate positions.
Federal Inspection Station is located at the center of the building and is sized to process 3,000 transfer passengers per hour. Passengers enter the primary inspection hall at the Sterile Level and then descend to the international baggage claim hall at the Concourse Level below. The two spaces are conceived together as a “gateway” into the United States and are connected under a long span roof that allows unrestricted layout and ease of movement at the baggage carousels. Exit control, secondary inspection, baggage re-check and security screening are all located on the Concourse Level.
Ramp Control Tower is composed of three levels: 1,400 SF cab at the top, offices and support areas below that and a mechanical area below that. Access to the ramp control tower is provided by a single egress stair and elevator. The four sides of the cab are surrounded by sloped clear laminated / insulated glass. Manually operated roller shades on all four sides will provide relief from direct sunlight. An accessible floor is provided for ease of telecommunications and data distribution as well as for a displacement HVAC system. The height of the cab is at elevation 426’ allowing the controllers a direct view of a majority of the apron; cameras are scheduled in certain locations where line-of-sight is interrupted by portions of the building.
Baggage Handling System: The outbound baggage room is centrally located on the apron level; it is accessed by tug ramps at five different locations to ease tug traffic congestion. Conveyors from the Main Terminal high speed baggage tunnel transition up through the basement level to the ceiling of the outbound bag room where they feed 21 make-up devices. The inbound baggage room in located on the east side of the building on the apron level; six double-sided drop belts will be provided. The inbound conveyors run at basement level to the Main Terminal high speed baggage tunnel.
Professional Services: The Tier 2 design team consisted of 26 firms. In addition to collaborating with the airport authority design staff, the program manager and the airline tenant, the Tier 2 design team worked closely with a separate design team developing a combined 10-mile long series of passenger people mover and baggage conveyor tunnels, many of which were designed to pass under the Tier 2 structure and be constructed concurrently with the Tier 2 project. Giuliani Associates was contracted to provide architectural services related to the coordination of the space and functional requirements of the airport authority’s maintenance and operations departments, the airline tenant, and federal agency tenants including Transportation Security Administration, Customs and Border Protection, Center for Disease Control, and Fish & Wild Life. Specific services included:
- Schematic design including alternate space plans
- Collaboration with United Air Lines design staff for the programming and conceptualization of the project
- Consultation with Metropolitan Washington Airports Authority staff to ensure compliance with design manual
- Design development including incorporation of United corporate standards into design
- Collaboration with multiple federal agency operations personnel to ensure functionality of facilities
- Coordination of engineering distribution systems with architectural features
