Engineering
This building represented a major departure from convention by having a big height with small floorplates. This was made possible by a stayed-mast structural system in which columns around the perimeter ("stays") are linked radially to the core by multi-story trusses ("spreaders") at two points along the tower's shaft. The residential and communications floors would have been cantilevered out from the central core, to avoid perimeter columns and maximize views.

Famous quotes containing the word engineering:
“Mining today is an affair of mathematics, of finance, of the latest in engineering skill. Cautious men behind polished desks in San Francisco figure out in advance the amount of metal to a cubic yard, the number of yards washed a day, the cost of each operation. They have no need of grubstakes.”
—Merle Colby, U.S. public relief program (1935-1943)
