5 Architecture Facts About the Willis Tower

For almost 25 years the Willis Tower, more commonly known as Sears Tower, held the title for the tallest building in the U.S. Second place isn’t bad, right? And as the 12th tallest in the world at a height of 1,451 feet, it is Chicago’s most beloved skyscraper.

Commissioning The Building

In order to house their rapidly growing company, Sears commissioned architects Skidmore, Owings & Merrill in 1969. Architect Bruce Graham and engineer Fazlur Rahman Kahn led.

Advancements in Architecture

The Willis Tower was the first to ever use a bundled tube structure. Kahn’s design was so revolutionary that it was later used for the world’s tallest building, the Burj Khalifa.

Inspiration

Graham’s design was inspired by a cigarette ad. He demonstrated the concept to a colleague by pulling cigarettes out of a pack to illustrate the 9 tubes at different heights.

How was it Built

Construction began in April of 1971 and was finished by May 1973. Economically efficient for a building its size, the cost to build was $150 million, about $800 million today.

The Skydeck

Willis Tower’s observation deck is what makes it celebrated. At 1,353 feet, visitors can feel the building sway on a windy day and see over the plains of Illinois on a clear day.

Wonderful Tour--Rachael was the best guide ever!!!

I highly recommend the evening tour when it is is starting to get dark. Seeing the buildings in the daylight and then light by night was great. It is all about the guide--Rachael (think she spelled it differently) was absolutely amazing. She really new her history and had an appreciation of the architects/architecture. You can tell she just really loves what she does.
