Spire1999 ft

This tower was intended to be as tall as the FAA height restrictions permitted - 2000'. It would not only have been the tallest in the world, but one of the most slender as well utilizing a basic 140' x 140' footprint with 8 projecting "fin" columns. It was these columns which would give the tower it's ability to resist lateral forces with a minimal of deflection. They were to be made of High Strength concrete with varying dimensions of 6'-6" x 33'-0" at the base to 4'-6" x 13'-0" in the upper levels. The central core (62'-6" square) would house elevators and other services permitting efficient use of the cruciform floor plates.

The 125 story project would feature a public observation area at 1,486' and a 600' steel framed spire and communications tower comprised from 12 steel perimeter columns.
