Seattle-Tacoma South Terminal Concourse

Completed in 2004, the Seattle-Tacoma South Terminal Concourse featured 14 new gates, four retail stores, nine food concessions, moving walkways, inbound and outbound baggage handling systems, loading docks, auditorium spaces, and airline offices. Clark also completed infrastructure work, installing new electrical feeders, reconfiguring the adjacent Air Cargo Road, and relocating airfield security gates and utilities. Throughout the project, Clark incorporated airline programming revisions and design changes as the aviation industry increased security subsequent to the September 11, 2001, terrorist attacks. In addition, the project team oversaw ground improvements, including regrading and expanding parking facilities and landscaping a new pedestrian bridge.

The team's attention to phasing and coordination minimized the impacts of construction on travelers, airport patrons, airport security, and general airport operations. Clark communicated closely with airport personnel to advise them of the upcoming and pending work. In addition, they worked with the Port of Seattle to allow all of the airport’s follow-on tenant work to proceed on schedule.

Several innovative measures incorporated into this project resulted in schedule time savings, cost savings, and increased quality. These included a composite coordinated shop drawing process, which created a smoother field installation process, and the use of shotcrete for the below-ground utilidor.
