One Peachtree Center, Atlanta's latest highrise tower, will measure 62 stories high (860 ft) with 1.42 million sq ft of office space when completed next July. It will also become the tallest concrete building in the state and the fourth tallest concrete structure in the world. Adjacent to the tower is a 1.1 million sq ft mixed-use structure with parking for 2,885 vehicles, connected by a bridge crossing Peachtree Center Ave. The project, however, is impressive for more than its size and scope. It also demonstrates the ability to construct a very tall concrete frame structure with a sophisticated floor framing system. The structural design—and ultimately redesign—incorporates state-of-the-art structural analysis technique and innovative engineering that shaved $1 million off the $105 million price tag. Specifically, the contractor and subcontractor did extensive value-engineering on the project, which modified the tower's concrete framing system, while remaining true to the aesthetics of the original design.
