This is my eleventh skyscraper based off of Spencer Rezkalla's original design, and my twelfth overall. Upon completion in 1972, the former Standard Oil Building was built to serve as the headquarters of the Indiana-based Standard Oil Company whose former headquarters was at South Michigan Avenue and East 9th Street. In 1985, the building was renamed to the Amoco Building after the company changed names. After the building was sold for an estimated $430 to $440 million to The Blackstone Group, it was renamed to its present title, Aon Center, on December 30, 1999. However, the Aon Corporation did not become the building's primary tenant until 2001.
This model is my fourth skyscraper from Chicago. Originally, I was going to complete my Daley Center model before this one. But considering the fact that I actually finished designing this model back in October 2009, I figured it was high time I get this one finished already. This model took about three days to design, nearly 15 hours to build, and a whopping year and a half to complete. Model completed May 28, 2011.
The former Standard Oil Building was given the nickname "Big Stan" after its completion because it was the tallest building in Chicago and the fourth tallest in the world at 1,136 ft tall. A year later, however, it was dethroned by the Sears Tower which became tallest in Chicago and the world. Today, the Aon Center is Chicago's third tallest building with the Trump Tower having surpassed it as well in 2009. Had the recently cancelled Chicago Spire ever been built, the Aon Center would have been just above half the height of the would-be 2000 ft spire.
The main outdoor plaza lies just across the street from Chicago's Grant Park. At night, the building is sometimes host to messages lit using lighting on several floors to form letters. These messages are always visible on the building's south side facing Grant Park. Some past messages have been "BEARS" and "SOX" in support for the local football and baseball teams, "2016" for rallying of the failed Chicago bid for the 2016 Olympic Games, and "USA" on the night that Barack Obama won the 2008 presidential election.

The rooftop details; including HVAC, radio equipment, and a communication antenna that was installed in mid-2009.
Because each side of the tower is facing a different direction, I had to use bars underneath the skin to bind the two portions of each of the tower's faces together. The corners are then connected via hinge bricks. The model also seperates into five modules that are held together via eight technic connector pins at each seperation point.
This is a terrific model, like all of your others. This model actually inspired my interest in all chicago skyscrapers. I have recreated this using the same technique used by you and Spencer. I've made some other chicago skyscrapers, which I'll upload soon
Rocco, this model is awesome..it looks really realistic and so detailed...nice construction..i am speechless..never expect that it will look so awesome...
And now some private things...i can't write emails or answer some emails to you cuz my email- servers is completely down..i hope that it's repaired in about 2 weeks..

Yes, the only Chicago buildings I've built are the four tallest - which Rocco has now also completed with the finishing of the Aon Center. These four also happen to be the only Chicago supertalls with roof heights over 1000ft.
Unfortunately I am in the camp that sort of hopes the Chicago Spire never gets built - I don't think I could come up with a good model of it at my scale!
