Architectural precast concrete panels and exposed aggregate cladding, inlaid with granite, provided the exterior façade for this 30-story office building in downtown Charlotte, North Carolina. The lower three floors of the building were clad with granite whereas the upper floors were clad with architectural precast concrete. The frame of the building is structural steel with steel columns encased in concrete. Adjacent to the building is an all-precast, prestressed concrete 10-story parking structure which can accommodate 1043 vehicles. The total cost of precast concrete components for both structures was about $7.25 million. This article discusses the role that precast concrete played in the design, production and erection of this prestigious project.
