Stadium-bowl concrete work, two-thirds complete, is expected to be done by the fall.

Concrete work on the New Atlanta Stadium for football’s Atlanta Falcons is two-thirds complete and expected to be done this fall, says Wayne E. Wadsworth, principal in charge for the stadium’s general contractor, the Holder-Hunt-Russell-Moody Joint Venture, which holds a $1.078-billion guaranteed maximum price contract.

For the structural concrete bowl, the work is all about the megacolumns that will support the structural steel for the signature kinetic roof, says Wadsworth. The big push is to clear the playing field of all concrete operations by the summer to make way for the cranes that Derr & Isbell Construction will use to erect the roof's steel, including the megatrusses that will support the movable "petals." Steel work is scheduled to begin this fall.

The stadium, designed by architect HOK with structural engineer Buro Happold Consulting Engineers PC, has a roof that opens in its center, mimicking the opening of a camera lens. The stadium is expected to open for the 2017 football season.
