how much did it cost to build the sears tower
Willis Tower As Sears continued to offer optimistic projections for growth, the tower's proposed floor count rapidly increased into the low hundreds, surpassing the height of New York's unfinished World Trade Center to become the world's tallest building. The height was restricted by a limit imposed by the Federal Aviation Administration (FAA) to protect air traffic. The financing of the tower was provided by the Sears company. It was topped with two antennas to permit local television and radio broadcasts. Sears and the City of Chicago approved the design, and the first steel was put in place in April 1971. The structure was completed in May 1973. The construction cost about US$150 million at the time,[18] equivalent to $830 million in 2018.[19] By comparison, Taipei 101, built in 2004 in Taiwan, cost around the equivalent of US$2.21 billion in 2018 dollars.[20]
Willis Tower The Willis Tower, built as and still commonly referred to as the Sears Tower, is a 110-story,[4] 1,450-foot (442.1 m) skyscraper in Chicago, Illinois, United States.[3] At completion in 1973, it surpassed the World Trade Center towers in New York to become the tallest building in the world, a title it held for nearly 25 years and remained the tallest building in the Western Hemisphere until 2014 and the completion of a new building at the World Trade Center site. The building is considered a seminal achievement for its architect Fazlur Rahman Khan.[5] The Willis Tower is the second-tallest building in the United States and the Western hemisphere – and the 16th-tallest in the world. More than one million people visit its observation deck each year, making it one of Chicago's most popular tourist destinations. The structure was renamed in 2009 by the Willis Group as part of its lease on a portion of the tower's space.
