Design and construction

edit
 
Interior

The building, was constructed between the years 1962 and 1964, and utilizes a concrete structure.[1] At the time of its construction, it was Chicago's tallest concrete office building.[2] The building is designed with an exposed structure and adheres to the modernist architecture style.[2] The building utilizes a deep foundation system.[2]

This was the first building to utilize the shear wall frame interaction system conceptualized by its engineer, Fazlur Khan of the firm Skidmore, Owings & Merrill.[3] Kahn adapted the tube system he had innovated with the design of The Plaza on DeWitt by creating a tube-within-a-tube, with both the building's core and its perimeter being hollow and rigid tubes that support the tower, allowing for column-free interior space.[2]

At its lower portion, the façade of the tower juts back slightly in a curve.[2]

The building is connected to the Chicago Pedway system, with the Pedway featuring retail spaces in the area where it passes beneath the tower.[2] An underground Chicago Pedway passage connects the building to the Richard J. Daley Center across the street.[2]

The building has a small plaza featuring an untitled sculpture by Joan Miró.[2]

Fire

edit

The Cook County Administration Building saw a structural fire occur on the 12th floor of the building on October 17, 2003.[4][5][6]

The fire was started in a supply room[7] by a faulty light fixture and resulted in the deaths of six people.[8][9] The City of Chicago, in addition to several other defendants, paid $100 million to the families of the six victims after litigation,[10] citing multiple failures.
