The $700‐million World Trade Center, its two 1,350‐foot towers the largest buildings in the world, was dedicated formally yesterday by Governors Rockefeller and Cahill.
In a message read at the ceremonies in the purplecarpeted lobby of the northernmost of the twin, 110‐story towers, President Nixon hailed the center as “a major factor for the expansion of the nation’s international trade.”
The huge towers are set on bedrock 70 feet below street level and are designed to sway in a maximum arc of 11 inches in high winds. A computer fed by 6,500 sensors regulates heat and air‐conditioning, shutting them down on weekends. It will turn on diesel generators to make electricity if there is a blackout. In fact, the center uses more electricity than many small cities.
