With a few notable exceptions, tilt-up construction methods have traditionally been applied to buildings of one or two stories. However, the economies that are possible using conventional tilt-up construction methods are realized to an even greater degree in multistory applications, where panel heights may exceed 50 feet.
In June 1979, ground was broken for a 45,000-square-foot 4-story office building, Corporate Center I. It was built using full-height, load-bearing tilt-up wall panels. The interior structure was constructed with conventional steel columns and beams and with open-web steel joists and concrete floor slabs. The walls were designed to support the perimeter roof and floor loads as well as to act as shear walls for the lateral building loads. Both roof and floors act as diaphragms with shear connections at the walls. Exterior wall panel finishes were to be a combination of smooth concrete and exposed 2-inch limestone aggregate. Corporate Center I took just 7 months to progress from foundation construction to a ready-for-occupancy status, during the following year a twin building was constructed in the same amount of time.
