The major investors in this private venture were Bagley Wright (1924-2011), Ned Skinner, Norton Clapp, John Graham, the architect, and Howard S. Wright Construction, the main contractor. They had just one year and four days to construct the Space Needle, to be completed for the opening of the Seattle Century 21 World's Fair.
Earthquake Resistant, Gale Tolerant
The Space Needle is located in Seattle Center at 203 6th Avenue N. The site was the former location of the City of Seattle fire station. It is made of three I-beams weighing 45 tons each. It has 24 lightning rods on top, a revolving restaurant 500 feet above ground, and a skyline (100-foot) level restaurant added later. It has a glass elevator.
According to the construction firm (Howard S. Wright Construction Co.), the foundation of the Space Needle consists of 5,850 tons of concrete and steel, resting on a 30-foot foundation, with the center of gravity just above ground level. The firm states that, "Its earthquake resistance is twice that required by code, and its wind resistance allows it to tolerate gales over 150 miles per hour" (Wright Construction Co.).
The Space Needle was designated a historic landmark on April 19, 1999.
