In the Northwest region of the United States, where the Washington State cities of Seattle and Tacoma lie, mountains, forests, and ocean come together in a dramatic way that is most often captured in pictures of Mount Rainier. Air travelers have been denied the pleasure of these views by an airport terminal that for many years has shut in passengers. But with the expansion of the Central Terminal at the Sealtle-Tacoma International Airport, all that will change.
The Central Terminal, built in 1949, originally had observation decks From which visitors could watch landings and take-offs. Once renovations were made and restrictions were tightened because of security considerations, the terminal lost that capacity. Chosen from a field of internationally renowned architects, Fentress Bradburn was commissioned to design the 250,000-square-foot expansion of the 50-year-old terminal. Centerpiece of the project is a 350-fool-long glass wall that stonds 60 Feet high. This wall creates a transparent expanse that will afford visitors spectacular views of the airfield, all the way to the Olympic Mountains.
The glass itself is curved in two directions, both vertically and horizontally, and is engineered for support by Advanced Structures Incorporated. This transparent vertical plane offers contact with the outdoors that will showcase the region ond invest Sea-Tac, as it is known informally, with the qualities of a true gateway. The glass woll wraps around a newly created civic space that will feature concessions, art, and interactive educational experiences in an area patterned after Seattle‘s famed Pike Street Market.
Behind the aesthetics are major upgrades that will increase the airport‘s capacity and enhance service to passengers. These include features ranging from self check-in podiums ond Internet connections for laptop computers, to extensive retail and restaurants that specialize in the cuisine of the Northwest region. Other features include baggage make-up facilities, ramp level infrastructure, and a concessions distribution center.
One unusually challenging aspect of the project is its phasing. The Central Terminal Expansion is located at the intersection of four concourses, adjacent to the aircraft parking area operated by Horizon Airlines, the airport‘s busiest airline. The project involves maintaining seamless airporl operations during relocation of airfield utilities, excavation of a basement, alternation of baggage-tug routes through the construction area, relocation and consolidation of security checkpoints, and modifications of the terminal from the curbside inward.
