Thornton Tomasetti was the structural engineer for Great American Tower, Cincinnati’s tallest building. The 41-story high-rise contains a 525,000-square-foot, 1,700-car parking garage on 11 levels; an 825,000- square-foot, 33-level office tower above a portion of the garage; and a public promenade with 25,000 square feet of retail space.
The building’s core and exterior have been built using environmentally friendly and efficient practices, earning it LEED Gold and making the tower Cincinnati’s greenest building. The structural skeleton includes 5,800 tons of structural steel and more than 63,000 cubic yards of concrete. Two thousand glass and aluminum panels comprise the tower’s skin.
Office floors are column-free, affording tenants flexibility for future office reconfigurations, and floor-to-ceiling windows provide generous daylighting to the open space. Aligned floors connect Great American Tower to 303 Broadway at Queen City Square, a mid-rise structure for which Thornton Tomasetti was also the structural engineer.
Thornton Tomasetti was the specialty engineer to Great American Tower’s prime steel contractor for the skyscraper’s crown, a 400-ton tiara. The award-winning 130-foot-tall by 150-foot-wide exposed steel, elliptical tiara brings the building height to 665 feet. Thornton Tomasetti provided integrated modeling services, including a fully developed Tekla model, connection design and shop drawings.
