Although it was never built, the 2003 design for a 2,000-foot tall, 118-story large-scale mixed-use tower in downtown Chicago incorporated architectural and structural engineering advances that marked an important milestone in high-rise development. The next-generation stayed-mast structural system introduced for the project enabled a smaller and less-expensive floor plate to support a far taller tower.
