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).
The building was developed and leased by Arthur Rubloff & Co. The Brunswick Corporation, at the time experiencing rapid growth in its sales, signed a multimillion dollar 20-year lease as its anchor tenant. The building would become its new headquarters, replacing the headquarters it had occupied for sixty years on South Wabash Avenue. The company had for several years already been considering relocating its headquarters. Brunswick Corporation's lease was key in the project's financing. The deal with the Brunswick Corporation was secured for Arthur Rubloff & Co by Perry S. Herst Jr., who was (at the time) a young real estate broker working under Arthur Rubloff. Herst convinced the company that having its name adorn the planned $35 million downtown skyscraper would advertise it as a successful business. Also part of the pitch was that its location was across-the-street from the then-planned Chicago Civic Center (today known as the Richard J. Daley Center). The positive reputation of Skidmore, Owings & Merrill (contracted to design the building) also attracted the Brunswick Corporation.
The land for the building was secured in 1960, with several investors aiding in the acquisition of a quarter-block assemblage of parcels. 44,150 square feet (4,102 m2) of parcels was acquired, including the properties on which numerous buildings stood: a 17 story Chicago Title and Trust Building, a building a 69 W. Washington, a 13 story office building at 30 N. dearborn, and seven additional buildings. Investors financed and built the skyscraper through a partnership named Washington-Dearborn Properties, Inc., and the George A. Fuller Company was selected as the contractor.
The original late-1961 announcement for the project touted that it was intended to be the "largest and tallest [skyscraper] contracted in the heart of the Loop since the early 1930s", with preliminary plans at the time being that it would stand 35 floors, with 500 feet (150 m) tall, and contain 800,000 square feet (74,000 m2) of space. Brunswick, the namesake anchor tenant, was to occupy roughly one-fifth of the building's rentable floor space. It was ultimately somewhat smaller in size than this initial vision.
The building, was constructed between the years 1962 and 1964, and utilizes a concrete structure. The building has 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. The building features 690,000 square feet (64,000 m2) of space. It stands 475 feet (145 m) tall, and contains 35 floors.
The building was designed by Skidmore, Owings & Merrill engineer Fazlur Khan and architect Bruce Graham. It was the first building to utilize the shear wall frame interaction system conceptualized by Kahn. 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. Michael Saphier Associates Inc. (an office space planning firm) advised on the building's interior layout.
As civic center that was being developed across Washington Street contemporarily (the Richard J. Daley Center) was also being designed by Skidmore, Owings & Merrill, Arthur Rubloff & Co. requested that the architectural firm incorporate some architectural style cues from the planned complex. Herst commented that he believed that the two projects could compliment each other in a manner that could give Chicago a space similar to New York City's Rockefeller Center.
