SeaTac Airport Concourse C Expansion

FORMA completed this $10M occupied expansion at SeaTac Airport–linking new ground level gates to the existing Concourse C terminal via elevators, exterior stairs and a series of covered, semi-enclosed walkways.

Complex logistics and construction sequencing on this active, highly sensitive project site were coordinated with Alaska Airlines personnel, Port of Seattle and SeaTac representatives, and State and Federal authorities.

FORMA Construction was recognized by the Port with the 2015 Champion of Inclusion award for our work on this project.
