The Howard Wright Construction Company broke ground at the Space Needle site on April 17, 1961. The result of a design collaboration among businessman Edward E. Carlson, architect John Graham and University of Washington architecture professor Victor Steinbrueck, the Space Needle was built for the 1962 Century 21 Exposition (World's Fair) in Seattle. With the addition of the final torch tower, the construction of the 600 foot Space Needle was completed on December 8. 1961. Seattle's Pacific Car and Foundry Company was the subcontractor for the steel fabrication and erection.

This photo depicts the core section of the Space Needle under construction, with the crane on the left hoisting supplies to workers. Pacific Car & Foundry Company also designed a derrick crane that climbed up inside the core and reached over the top to hoist the huge fabricated steel sections into position.
