Concourse D Hardstands

This new design-build 32,500 SF building on the east side of Concourse D in the existing North Ground Transportation Lot at Seattle-Tacoma International Airport houses multiple holdrooms for the hardstand operations. Osborn Consulting led the civil engineering for the project, performing design of site layout, utilities, and stormwater drainage while also providing construction management support services. The project had multiple challenges including resolving conflicts with existing active utilities, providing adequate maneuvering area for COBUS operations and fire fighting equipment, and providing accessible routes for pedestrians.
