The site preparation began with the demolition of a Firestone Tire dealership in February 2006, and on February 28, 2006, the excavation and blasting of a -deep hole for the below-grade parking garage began. Over of explosives were used during its excavation and it took just over 60,000 dump truck loads to remove all of the excavated material from the site, some of which was used in the construction of a third runway at Charlotte-Douglas International Airport.

The building was constructed by Batson-Cook Construction, with ready mix products from Concrete Supply Co. and structural engineering firm TRC International Ltd, of Sarasota, Florida.

Features

It is the tallest building in the Levine Center for the Arts (formerly the Wells Fargo Cultural Campus) and the largest building in Charlotte, which will have a footprint. The complex will also include a 46-floor condominium tower (future), the Harvey B. Gantt Center for African-American Arts + Culture, the Mint Museum Uptown, the Knight Theater, the Bechtler Museum of Modern Art, and a History Museum. The building has achieved LEED Platinum status by including water-saving plumbing devices, a water storage system that will treat rainwater to be used for cooling tower make-up water, and a green roof. Rock that was blasted for the parking structure is being recycled by hauling it to a local quarry, where it will be crushed for gravel.

The facade of the structure is illuminated by hundreds of programmable color-changing LED and metal halide luminaires with design work by Gabler-Youngston Architectural Lighting Design. The facade lighting system provides various shows and effects. Due to the tower's high visibility over the east corner of Bank of America Stadium, the LED lights are used during key moments of sporting events played there. For example, if the Carolina Panthers are playing, the tower lights up blue for Panthers touchdowns. During the ACC Championship Game, whenever a team scores a touchdown, it lights up in that team's color.
