Project Description


Port of Seattle

Contract Value:

$1.5 Billion USD

At Seattle-Tacoma International Airport (SEA), the S Concourse is the main hub for international passengers. To meet the growing demand for international travel, the Port of Seattle is renovating the S Concourse into a modern and improved doorway for the Pacific Northwest and advancing the region as a leading tourism and business gateway. Since the debut of the S Concourse over a half century ago, the existing building has had trouble sustaining optimal service. Due to the dramatic increases in passenger volumes and aircraft operations, expanded security regulations and an evolving airport experience for passengers, dining and retail, and airlines, the facility upgrades will include the following:

  • Modernizing building systems for greater operational and environmental efficiencies
  • Earthquake resiliency that prioritizes seismic updates
  • Design, amenities, and art focused on your wellbeing and comfort
  • Pacific Northwest placemaking with more spaces for restaurants, shops, and lounges that feel like home

WT is actively providing cost estimating support services on projects under the direction of Capital Development at the Port of Seattle. Based on-site at the SeaTac International Airport, WT continues to provide a full suite of project cost, controls and procurement management on the airport’s airside, landside, terminal and utility development program.
