St. Louis Firm Engineers Renovated Museum at Gateway Arch


IMEG Corp. in St. Louis provided engineering design and services for a $109 million renovation and expansion of the Museum at Gateway Arch National Park, which reopens to the public today.

Engineers for IMEG’s office in St. Louis provided mechanical, electrical, and telecommunications design, along with construction administration services for the multi-year project, which added a 2,000-square-foot grand entrance facing Luther Ely Smith Square and the Historic Old Courthouse. A new three-story atrium brings natural light and openness to the subterranean museum spaces – all of which have been renovated and modernized.

The museum is seeking LEED Silver certification and is one of six IMEG projects included in the Gateway Arch Park Foundation’s initiative over the last several years to improve the Arch grounds and riverfront. 

IMEG is headquartered in Rock Island, Ill., and has 1,200 employees at more than 35 national and international locations. It is one of the largest engineering consulting firms in the U.S. specializing in high performing building systems, infrastructure, and construction-related services. For more information, visit
