When considering the diagonal grid—or diagrid—structural framing system, the engineers and architects realized that the corners of many floor plates would extend as much as 20 ft (6 m) beyond the nodes of the diamond-shaped framing. The solution: chamfer the corners, adding interest and movement to the structure.

To maximize the amount of open floor space in the tower, the structural core was located along the west side rather than in a central position. To correct the eccentricity this scheme creates, lateral support and stiffness were added along the east side of the structure.
