The recently completed major addition to the St. Louis Science Center utilizes approximately 20,000 sq. ft. of Citadel Envelope 2000® Rout & Return (RR) System metal composite material (MCM) panels. The panels were finished in Shasta White and Silver Gray.

The 13,000 sq. ft. metal-clad addition replaces an air-supported exhibit dome that was nearing the end of its lifespan. The new building is a permanent home for traveling exhibitions and major displays. The project also included a distinctive rooftop terrace to be used for outdoor educational programs and special events.

The St. Louis Science Center is regarded as one of the top five science centers in the United States and serves 1.2 million visitors annually.

The Citadel panels were installed by Kuenz Heating & Sheet Metal, St. Charles, MO. “The job was fairly straight-forward,” according to Ron Bradley, vice president and project manager, “although we had to deal with many different panels heights because the seams had to align with the aluminum plate on the existing building. We did all of the field measurements and supplied a fab sheet for each panel to the fabricator. The only other challenge was the half-round vertical accent columns—keeping those in shape is always a little tricky. But the job really turned out great.”

The Citadel MCM panels were fabricated by Castle Metal Works, Chicago. Design services for the addition were provided by PGAV Destinations, St. Louis. The construction manager on the project was Alberici Constructors, St. Louis.
