In 1973, the Sears Tower was under construction. The Sears Tower was the first structure to adopt this novel design. It was both structurally and economically efficient; at 1,450 feet, it supplied more room and ascended higher than the Empire State Building while costing much less per unit area. When it was completed in 1990, the Sears Tower was the tallest building in the world.
When it was built, the Sears Tower was intended to be only one of several high-rise buildings in Chicago's Loop community center. However, the project was delayed for many years by funding issues and the S&L crisis, and it was not until 1985 that construction finally began. Even then, the builders had difficulty finding a contractor willing to take on such a large project, and many other firms were involved in some stage of the work before Taubman Centers bought the rights to build additional towers in 1996.
The Sears Tower is currently the second-tallest building in Chicago after the John Hancock Center. It holds this distinction despite being only half as tall as its rival (1,451 ft vs 2,572 ft). This is because most other buildings were designed with height as a priority over width. By comparison, the Sears Tower is almost twice as wide at its base!
When the Sears Tower was completed, it was thought that this new skyscraper would be the catalyst for bringing down the other major Chicago skyscraper, the IDS Center.
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 the architect Edward Durell Stone and modeled after Michelangelo's Palazzo della Ragione in Milan, Italy.
The tower was never intended to be a permanent structure but instead used as a replacement for the aging Merchandise Mart building, which had been sold to provide funds for the construction project. However, due to its success, the tower has become an icon of Chicago and has been called "the city's crown jewel" and "the fourth pillar of the Chicago skyline".
Its height makes it the second-highest building in Chicago behind only the John Hancock Center (formerly known as the Hancock Observatory).
There are several reasons why the tower has become so popular with tourists: it is one of the most expensive buildings to rent out, the observation deck on the 100th floor has great views of Chicago, there are also guided tours you can take of the building that include viewing galleries with amazing views.
Furthermore, the tower houses numerous shops and restaurants on each level up to the 96th floor, making it a popular attraction with visitors to Chicago.
Why was the Sears Tower constructed? The objective for the creation of this enormous commercial edifice in 1969 was to group many Sears, Roebuck & Co. personnel in the Chicago region under one roof. As the world's largest retailer at the time, the firm employed a stunning 350,000 workers working only in this field.
The building was also intended to make Chicago the center of the men's clothing industry. At the time it was completed, it was the tallest free-standing structure in the world.
It took 10 years and $150 million to build the Sears Tower, which at the time was considered a huge investment for a company that sold its products over the counter and had annual revenues of $1 billion. But the skyscraper was a great success from the beginning: it contained more than 8,000 square meters (86,000 sq ft) of selling space and became the main outlet for Sears' merchandise in the Midwest. The building also served as a landmark for travelers on the Eisenhower Expressway, the first freeway that connects Chicago with its suburbs.
In addition to its retail use, the top three floors of the tower are occupied by offices, while the rest is given over to rental apartments. There are also several food courts and a movie theater in the building.
Construction on the Sears Tower began in 1966 and it was opened for business on February 14, 1973.
