description
The Aon Center was built between 1970 and 1973. It is 346 meters high to the roof edge and has 83 floors, making it briefly the tallest building in Chicago after its completion. It surpassed the John Hancock Center , built in 1969 and 344 meters high, by two meters and was exceeded by almost one hundred meters in 1974 by the 442 meter high Willis Tower (formerly Sears Tower). From 1974 to 1990, however, the Aon Center was the fifth tallest building in the world for 16 years, and by 2009 it was the second tallest skyscraper in Chicago. Today it is still the third tallest building in Chicago and the ninth tallest in the United States , after One World Trade Center ( New York City ), Willis Tower, 111 West 57th Street (New York City), 432 Park Avenue (New York City), 30 Hudson Yards (New York City), the Empire State Building (New York City), Trump Tower (Chicago) and the Bank of America Tower (New York City) . The skyscraper housed the headquarters of the insurance company Aon plc until it was relocated to London in 2012 . Since then it has been the Group's second most important location. Apart from a few technical facilities for operation, the entire building is used exclusively for offices. The 83 storeys of the building have a total floor space of around 334,000 square meters. In contrast to other skyscrapers in the city, such as the Willis Tower or the John Hancock Center, the Aon Center does not have any public facilities.
The building was constructed using the same construction method as the former World Trade Center (completed in 1972 and 1973) in New York City and is similar in design, but is around 70 meters lower.
Others
The Aon Center was originally clad with 43,000 Carrara marble slabs. On December 25, 1973, a slab fell from the facade and broke through the roof of the Prudential Center . After an investigation in 1985 revealed that the slabs were cracked, they were replaced by white granite slabs between 1989 and 1992 , at a cost of $ 80 million.
In March 2010, it was announced that the Aon Center is one of the most energy efficient and environmentally friendly buildings in the United States.
