Tower Roof Beam Keychain
 

The tower roofs were constructed by laying a lightweight aluminum grid of I-beams with interlocking cross pieces.  This made a series of brick patterns supporting the thin translucent fiberglass roof panels.  The panels were adhered to the beams with black tar like adhesive. Remnants of these beams and roof panels continue to show the contact points of these two materials with the remaining dried adhesive.
 

Only several of these beams remain intact (one pictured below) but recently a damaged and twisted beam was found and fished out of one of the Tent of Tomorrow's columns. This piece was recycled into the keychains offered as a reward for your donation!

Here are some vital statistics about the towers of the New York State Pavilion
 
OBSERVATION TOWERS
3 reinforced concrete Observation Towers
  Top of Steel 
Height of tower No. 3 above ground 226' 
Height of tower No. 2 above ground 181' 
Height of tower No. 1 above ground 85' 
 
Each tower has an outside diameter of 12'-8" and the tower walls are 16" thick.

Structurally, the towers are prestressed by means of the Stressteel post-tensioning system.

Each Observation Tower platform is a steel platform 64' diameter suspended by cables from overhead cantilevered girders.

The foundation for the three towers is a large 7' thick pile cap supported by 207 steel pipe piles. The concrete work for the towers is by the slipform system, accomplished in three increments. The rate of slip is between 12" to 18" per hour.
 
The height of each platform above the ground is:
Platform No. 1 65' (Tower No. 1)
Platform No. 2  160' (Tower No. 2)
Platform No. 3 191' (Tower No. 3)
Platform No. 4 216' (Tower No. 3)
