At $362 million, the Intermountain Medical Center is the largest commercial building project presently under construction in Utah. Approximately 12,350 tons of structural steel will be used throughout the 1.3 million sq. ft. hospital campus which includes a heart center, tertiary hospital, patient care tower, oncology center, ambulatory surgery center, and a women’s and newborn center.

The largest building in the project is composed of a four-story base that supports the eight-story heart center and the 16-story patient care tower. The Intermountain Medical Center is the flagship hospital for Intermountain Health Care, one of the leading health care providers in the nation.

IMC is located along the Wasatch Fault, an active fault capable of producing a magnitude 7.3 earthquake. In the event of a large earthquake, structural lightweight concrete was specified to reduce seismic demands and dead loads on horizontal framing members, columns and footings.

In addition, high strength-to-weight ratio of structural steel made it ideal for seismic design by limiting building mass. IMC is the largest project to date in the United States constructed with Buckling Restrained Braced Frame (BRBF’s) technology. Two of the test braces experienced cyclical loading at forces above 1.3 million lb. Completion is slatted for the latter part of 2007.
