Port of Seattle Commission Unanimously Approves GMP for Sea-Tac IAF

SEATTLE - On September 25, Port of Seattle Commission members unanimously approved a Guaranteed Maximum Price for the International Arrivals Facility at Seattle-Tacoma International Airport, a progressive design-build project that will significantly enhance the international passenger experience and advance the Puget Sound region as a leading tourism and business gateway. As part of their recent meeting, the Port Commission also adopted a revised completion schedule and various other recommendations made by an independent Executive Review Panel (ERP) earlier this month aimed at moving the project forward to a safe and successful completion.

Approval of the GMP marks a critical milestone for the IAF project as it represents the culmination of six months of intense collaboration between Clark and the Port of Seattle. Under a revised timeline, construction on the IAF is scheduled to be complete on May 31, 2020 and will open to passengers in August 2020, following extensive systems and use testing by the Port, airlines, and federal agencies.

Clark is constructing the three-story IAF on the east side of Sea-Tac's Concourse A, amid an active airport campus. The 450,000 square-foot facility will nearly double the airport’s international wide-body capable gates from 12 to 20.  The project includes an elevated sterile corridor, which connects to the existing concourse and an iconic pedestrian bridge that will span approximately 900 linear fee­­­t from the new IAF to the South Satellite. The IAF also will include a number of features, such as new baggage claim carousels and technologies for faster passport check clearance, which are designed to enhance safety, efficiency, and the traveler experience.

With design work on the IAF nearly complete, construction is in full swing. Steel erection on the project’s sterile corridor is 50 percent complete with the IAF building steel following close behind. Roofing activities have commenced on the IAF, and preparations are being made for the building’s glass curtain wall system. Foundations work also is underway for the iconic aerial walkway.

Sea-Tac is among the top 10 busiest U.S. airports. When complete, the IAF will accommodate demand for international travel and improve arrivals efficiency for international travelers.
