During the 1960s and 1970s, he rose to prominence with his designs for Chicago's 100-story John Hancock Center and the 110-story Sears Tower, later renamed Willis Tower, which was the tallest structure in the world from 1973 until 1998. When it was demolished to make way for the 1,700-foot-high O'Hare International Airport Terminal 3, Fazlur Khan was quoted as saying: "I feel very sad to see such a great building go down.".
The Sears Tower is now ranked as one of the 10 most destructive buildings in U.S. history. It caused widespread damage when it fell during its demolition, taking with it 13 people who were working on its renovation. The total cost of the damage caused by the collapse of the tower has been estimated at $240 million.
Fazlur Khan was born on March 20, 1924 in Rajasthan, India. He moved to Chicago with his family when he was 11 years old and attended Roosevelt University for architecture school. He began his professional career after graduating in 1949 at the age of 24.
He became one of the leading architects of the post-World War II era, and is widely regarded as one of the founding fathers of the modern skyscraper style.
Willis Tower was the highest skyscraper in the world until 1998. After 18 years, Sears Roebuck & Company sold the tower and relocated. Willis Tower was renamed in 2009 after Willis Group Holdings, the multinational insurance broker that makes the Tower home in the Midwest.
An American icon with a long and illustrious history. Willis Tower is located in downtown Chicago and represents the future of work and recreation. The 110-story building is one of the world's tallest structures and the second-tallest structure in North America, making it difficult to overlook when admiring the city's skyline.
Willis Tower was designed by architect Peter Rice and built from 1988 to 1991. The 1,454-foot (442 m) tall skyscraper is named after its owner, Sears Roebuck and Company. When it was completed, it was the highest building in the world. Today, it still holds the title for the tallest residential building in the Western Hemisphere.
The building is made of reinforced concrete and has 87 floors above the ground floor. It contains 2,297 rooms including 22 suites on each floor. There are also three restaurants on site: Two atground levels and a luxury rooftop restaurant with views over the city. A visitor center on the 23rd floor provides visitors with a view of the city through high-speed elevators.
Willis Tower is used extensively as a television studio, being home to several entertainment shows such as "So You Think You Can Dance?" and "The Price Is Right". The top floor serves as a conference center with space for large groups to meet. This is particularly useful for trade shows where exhibitors can rent out all of the meeting rooms simultaneously.
Many people are curious about the rationale for the construction of the Sears Tower, which began in 1970 and continued until 1973. It is regarded as one of the tallest structures in the world. It has 108 stories and is located at 233 South Wacker Drive in Chicago, Illinois. The building was designed by Henry Ives Cobb and William H. Miner with architects from the architectural firm of Graham, Anderson, Probst & White. The foundation stone was laid on April 1, 1969, and it was completed three years later at a cost of $76 million.
Heavier taxes and financing difficulties forced the original developer, the Chicago Tribune, to file for bankruptcy in 1976. The paper's owner, Conrad Black, decided not to continue with the project, and the development was put up for sale. In 1978, the property was acquired by the Morton Salt Company who planned to move their headquarters there. But after only two years, they too withdrew from the project, leaving its future uncertain. In 1980, the property was transferred to the CNA Insurance company who also wanted to use the tower for offices, but again this plan did not come to pass and the building was left empty for several years.
In 1993, the Sears Tower was sold to a partnership composed of Argentinian investors that included Jorge Mas Canosa who had formerly been an executive with the Chicago Tribune.
The 110-story office tower, originally known as the Sears Tower, is a Chicago icon and one of the world's tallest structures. Its height makes it a landmark suitable for viewing from many areas of the city.
It was also the first building to be granted permission to use magnetic levitation (maglev) technology in a major building application. This maglev system uses electromagnets instead of gears or pistons to lift passengers up into the air with electric currents rather than gas. It can carry up to 500 people per hour from the ground floor to any other floor within the structure.
The tower has been called "the glass cube on legs" because of its unusual design. The bottom four floors are concrete pillars set in a square pattern. The top 96 floors are made of transparent glass, while the lower three are made of steel and concrete. The interior of the tower is also completely open to the public, allowing for great views of Chicago from any floor.
The tower was initially proposed by architect Helmut Jahn when he was just 23 years old. It took him more than 10 years to complete due to financial problems at its construction site. The last shipment of materials reached the tower site on January 17, 1973, and it was completed two months later on March 29, 1973.
An American Icon with a Long and Prominent History Willis Tower is located in downtown Chicago and represents the future of work and recreation.
The Sears Tower was designed by architect Peter Nicholl who also designed the John Hancock Center in Chicago. It was built by the W.R. Grace Company as their headquarters and main store location. When it opened in 1990, it was the first major skyscraper built in Chicago in over 10 years. The tower is named after its primary tenant, Sears, Roebuck and Company, who moved into the tower in 1975. Although they no longer operate out of the tower, it continues to be one of the most prominent buildings in the city and country.
In addition to being an icon for Chicago, the Sears Tower is also famous for being the highest occupied building in the world. Located at 108 stories above street level, the top of the building is where the majority of offices are located. There are only 7 other floors below this height which makes the Sears Tower feel even higher.
In addition to being impressive from outside, inside the building there are several unique features you cannot find anywhere else. One of them is a large Christmas tree displayed in the lobby every year.
