Lumen Field Exhibition Center

Offering space for 1,410 exhibit booths in the main hall, swing space, and concourse levels, the exhibition center is part of the larger Lumen Field sports complex that includes the professional football/soccer stadium, professional baseball stadium, and 2,000-car garage. The exhibition center's 100,000-ft² swing space extends below the adjacent six-story parking garage and serves as additional ground-level parking when not in use for exhibits. The structure is steel-framed with 90- by 90-ft column grids for quick construction. The post-tensioned long-span concrete in the garage conforms economically to the exhibition floor grid at the ground level. When the sports complex was completed, the event center doubled available exhibit space as compared to the previous Kingdome stadium.   MKA's civil efforts included site demolition, erosion control, and street frontage improvements, including curbs, sidewalks, and drainage.
