Sears Tower Biography
The Sears Tower is a skyscraper in Chicago, Illinois, and the tallest building in the United States, measuring from the ground to its roof. Measuring to the top of the antenna/spire, One World Trade Center passed it by 1.9 feet until only days before it was destroyed on September 11th, 2001—a short extension was installed on one of Sears' antennas in early September of that year.
Commissioned by Sears, Roebuck and Company, it was designed by chief architect Bruce Graham and structural engineers Srinivasa "Hal" Iyengar and Fazlur Khan of the firm of Skidmore, Owings & Merrill.
Designed as a headquarters for the Sears company with substantial extra space for expected expansion, the project turned out to be a financial disappointment as it was unable to attract renters and was sold to new owners in 1993 after achieving only about 50-percent occupancy for more than a decade. It has since attracted major corporate tenants and is considered an extremely desirable business location.
The building's official address is 233 South Wacker Drive, Chicago, Illinois 60606. It is a major tourist attraction, with thousands of visitors reaching its world-famous Sky-deck daily by means of special hi-tech elevators.
In 1969 Sears, Roebuck & Co. was by far the largest retailer in the world, with about 350,000 employees. Sears executives decided to consolidate their thousands of employees in offices that were sprinkled throughout Chicagoland into one building on the western edge of Chicago's Loop. With immediate space demands of three million square feet and predictions and plans for future growth necessitating even more space than that, architects for Skidmore knew that the building would be one of the largest office buildings in the world.
Sears leaders decided early on that the space they would immediately occupy should be efficiently designed to house the small army that constituted their Merchandise Group. Floor space for future growth would be rented out to smaller businesses until Sears could retake it. Therefore, the floor sizes would need to be relatively small, in order to have a higher window-space to floor-space ratio, and thus be more marketable to these prospective lessees. Smaller floor sizes necessitated a taller structure. Skidmore architects proposed a tower which would have large 55,000-square-foot floors in the lower part of the building, and would gradually taper the floor areas in a series of setbacks which would give the Sears Tower its distinctive, husky-shouldered look.
As Sears continued to offer optimistic projections for future growth, the tower's proposed height soared into the low hundreds of floors and surpassed the height of New York's unfinished World Trade Center, to become the world's tallest building. Restricted in height not by physical limitations or imagination but rather by a limit imposed by the Federal Aviation Administration to protect air traffic, the Sears Tower would be financed completely out of Sears' deep pockets, and topped with two antennae to permit local television and radio broadcasts.
