Cook County Administration Building

The George W. Dunne Cook County Administration Building (formerly known as the Brunswick Building) is a skyscraper at 69 West Washington Street in Chicago, Illinois. The building, constructed between the years 1962 and 1964, is 475 ft (144.8 m) tall, and contains 35 floors. It has a concrete structure. The building, engineered by Fazlur Khan of the firm Skidmore, Owings & Merrill, is notable for innovating the tube-within-a-tube structural system.

Originally built as a headquarters office for the Brunswick Corporation, the tower was later acquired by the Cook County government and now holds county government offices and courtrooms. Officially the "George W. Dunne Cook County Administration Building", its namesake is George W. Dunne (who served as president of the Cook County Board of Commissioners).

Design and construction

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

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. 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.

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

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

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

Fire

On October 17, 2003, a structural fire occurred on the 12th floor of the building. The fire originated in a storage closest in Suite 1240, used by Secretary of State's Business Services Division. Reported to building security at approximately 5:00pm and building security officers reporting the fire at 5:02pm via 9-1-1. The voice evacuation alarm was initiated at 5:03. Chicago Fire Department personnel arrived by 5:06 and firefighters confirmed an active fire at 5:10.
At 5:15, 9-1-1 received a call reporting that an individual is trapped by heavy smoke. This call would be followed by several additional calls from various individuals trapped in the southeast stairway, reporting that it was filled with smoke and that they are unable to exit the stairway due to locked doors. Calls from trapped individuals continued until 5:47.

Some individuals trapped in the stairway discovered the door on the 27th floor was not latched, and were able to escape from the smoke filled stairway. Thirteen individuals were unable to reach floor 27 and collapsed from smoke between floors 16 and 22, killing six of them.

The fire was reported as out at 6:39 pm.

A review into the handling of the fire, authored by James Lee Witt, was tasked with identifying what occurred during the response to the fire, shortcomings that occurred, and how to address them. Then make recommendations to improve deficient procedures and systems. The report was released in late 2004.
The report ultimately determined several critical factors contributed fire and loss of life:
* Lack of sprinklers on the 12th floor, enabling a small fire to start, spread and take hold;
* Chicago Fire Department's failure to conduct searches of stairways;
* The opening of the door in the southeast stairway on floor 12; allowing smoke and heat into the stairway;
* Locked stairway doors that prevented individuals from exiting the smoke filled stairway.
The report also found numerous other issues that contributed to the situation: inadequate evacuation training for building occupants, ineffective communication between 9-1-1 dispatchers and fire incident command, poor incident command procedures, and non-compliance with state fire code.

The National Institute of Standards and Technology (NIST) also preformed testing to assist the State of Illinois in understanding the fire's growth and smoke movement in the structure, particularly the southeast stairway. NIST also simulated fire growth and spread if fire sprinklers had been present on the 12th floor, determining that most likely, the fire would have remained contained to the storage room had sprinklers been present.

In April 2008, the City of Chicago, in addition to several other defendants, paid $100 million to the families of the six victims after litigation, citing multiple failures.

As of early 2017, at least 20 commercial high rises, including Chicago City Hall and 81 residential high rises, had missed a January 1st, 2017 deadline to have sprinklers installed and operational.

In media

In the film ''National Lampoon's Christmas Vacation'', the building is shown in establishing shots as Clark Griswold's workplace as a chemical engineer at a food company.
