The Port of Seattle Commission has authorized initial funding for the Seattle-Tacoma International Airport (SEA) S Concourse Evolution Project (SCE). The approximately $2.5-billion renovation will equip the 1973 facility with new sustainability features as well as add an additional 150,000 square feet of terminal space that includes a new upper concourse level; dual-level boarding areas for select gates; as well as new dining, retail and lounge amenities. The multiphase project is scheduled to start in 2027 and is scheduled to be completed in 2034.
“Today’s authorization to move forward with the S Concourse Evolution builds on the generational investments we are making at SEA to improve the passenger experience,” said Ryan Calkins, president of the Port of Seattle Commission. “The project will add critical seismic, structural, and building systems upgrades to improve long-term passenger circulation as well as operational efficiency.”
“The existing building is over half a century old, making it challenging for us to meet our goals of providing the best possible service to our travelers and tenants — this is a necessary upgrade,” said Wendy Reiter, SEA’s managing director. “As we’ve done in previous Upgrade SEA projects, we’re being innovative by building up and not out. We’re mindful of the fact that we have one of the smallest footprints of any major U.S. airport considering our passenger volume.”
“The design solution for the S Concourse Evolution project carefully balances required resiliency improvements to the existing structure and systems, increased efficiency for aircraft operations and building services, and modernization of the interior to enrich the traveler experience,” said Kevin Keady, business leader of buildings and places for the West Region at AECOM, the design firm for the project. “The design is inspired by local, indigenous concepts combined with pragmatic enhancements that will achieve greatly improved passenger service levels and meet the high standards travelers are accustomed to at one of the world’s busiest airports. We are grateful for the opportunity to work with SEA airport on this exciting project that will benefit the region for the next 50 years.”
