Museum at Gateway Arch

Museum at Gateway Arch Cited in National Engineering Competition


Innovative Building Systems Enhance Expanded Cultural Landmark

IMEG Corp. of Rock Island, Ill., has earned a National Recognition Award for exemplary engineering achievement in the American Council of Engineering Companies’ (ACEC) 52nd annual Engineering Excellence Awards (EEA) for its role in the renovation and expansion of the Museum at the Gateway Arch in St. Louis, Mo.

IMEG provided mechanical, electrical, and telecommunications design for the $108.9 million, 50,000-square-foot addition and 100,000-square-foot renovation project, located underground beneath the famed Gateway Arch. The project updated all infrastructure, modernized exhibits and galleries, and added new spaces including a learning center and a new west entrance facing the heart of downtown St. Louis.

Along with meeting historic preservation requirements and ambitious energy-efficiency goals, the project team incorporated technology to support “micro-climates” for special museum exhibits in order maintain specific and constant temperature and humidity levels. The result is a safe and comfortable environment for visitors and staff, properly conditioned spaces for the exhibits, and long-term energy savings through the use of high-performance building systems technologies.

The project is among 196 engineering achievements from throughout the nation and the world being recognized by ACEC as the year’s finest examples of engineering excellence, and eligible for additional top national honors. Judging for the awards program—known industry-wide as the “Academy Awards of the engineering industry”– took place in February, conducted by a national 30-member panel of built environment leaders, along with experts from government, the media and academia. Award criteria focuses on uniqueness and originality, technical innovation, social and economic value, and generating excitement for the engineering profession.

Recognition of all award winners including top commendations—20 Honor Awards, 16 Grand Awards and the prestigious “Grand Conceptor Award” for the year’s most outstanding overall engineering achievement—will take place at the annual EEA Dinner and Gala, a black-tie event to be held Tuesday, May 7, 2019, at the Marriott Wardman Park Hotel in Washington, D.C.
