Some of the canted steel columns traveling through the third level begin at ground level, and some at level three. All continue up to a transfer slab at level five located at the base of the central tower elevator core. The purpose of the canted columns is simple: to enable the core of the building at grade to be free of columns. The canted columns accomplish this by distributing the load of the tower above from the transfer slab to the super columns around the tower’s perimeter.
