SeaTac Airport $1.2B Renovation Plans in the Works

The Port of Seattle has issued an advance notice for a $1.2 to $1.4 billion renovation of the Seattle-Tacoma International Airport’s South Concourse. According to the Daily Journal of Commerce, the project will create a new customer amenity space, a reconfigured concourse, new premium lounge spaces and four gate pods that would double as seismic supports.

The South Concourse is currently the international arrival area which travelers pass through as they head for the new International Arrivals Facility. The existing building is comprised of seven levels and was originally built in 1973.

Several new contracting opportunities will be available according to Port of Seattle plans, including project management and project controls services, design services and general contractor preconstruction services. The port plans on using a project labor agreement as well. 

A tentative schedule indicates design work finishing in 2025, construction commencing in mid-2026 and the entire project completed by the end of 2031.
