History Of The Willis Tower

I. Introduction
The Willis Tower (originally known as the Sears Tower) was for years the tallest buildi

ng in the world. The original planning and design did not envision this record as a goal to be achieved or as a parameter to guide design. Fazlur Khan’s design for Sears Roebuck not only met the client’s goal of consolidating its Chicago-area employees into one central location while allowing for anticipated company growth, but did so with an innovative and cost-saving bundled-tube structural system. This building was arguably not just the culmination but the fulfillment of Chicago’s role in advancing the towering skyscraper as a centerpiece of modern architecture. Its particular design exemplifies the “form following function” dictum in both the advantages and drawbacks of that way of conceptualizing buildings. Its aesthetics magnify the aesthetic features and the drawbacks of the huge modern skyscraper.

The Willis Tower is 110 stories tall and 1454 feet high. Visitors can see five states from its observation deck on a clear day. The building has the highest elevator ride in the world. Its base covers two full city blocks. One way often mentioned to envision its bundled tube design is to think of a pack of cigarettes with nine cigarettes rising above the others. Two are pulled out to a middle level with two more slightly higher. Then three are pulled even higher with the last two pulled out to complete the design. Each of these cigarettes is seventy five feet square. The exterior design is that of a steel frame and glass curtain as pioneered in Bruce Graham’s Inland Steel building. The exterior frame is covered by twenty eight acres of black aluminum. Other statistics barely convey the superhuman scale of the Willi...

However its aesthetic and human deficiencies reveal that form follows function succeeds only insofar as we do not let constricted or provincial ideas about a building’s function limit what it becomes in the lives of the people who have to live and work there. There is a sense here that the Sears executives who commissioned it got exactly what they wished for and what they paid for. Few people feel affection for it like the Hancock Center as a civic symbol nor would many take it as a source of inspiration. The Willis Tower will stand as a monument to Fazlur Khan’s engineering imagination and as an indictment of the aesthetic and social imaginations of those who could not conceive of a workplace where people did more than clock in and perform their set tasks and functions. Remember that the Sears people originally conceived of the building as a 40-story cube.
