The elevators were to be "atomic-powered", capable of mile-per-minute speeds, and running on ratchets instead of suspended by cables. Wright's floor plan of the 528th floor shows it would be served by only one elevator shaft. The 76 elevators would be divided into five banks or groups, with each elevator group serving a hundred-floor segment of the building. Wright explained that there would be 76 elevators, each having five-floor-high tandem cabs, serving blocks of five floors simultaneously. The late 1990s and early 2000s saw substantial increases in the load-bearing strength of concrete, making it possible to build entirely in this stiff material. This also could have been solved by placing a tuned mass damper somewhere within the tower as was done in the Citigroup Center and Taipei 101, although this design innovation was not well-known until decades later. Though Wright acknowledged this problem in his original proposal, he believed the tripod design of this tower (similar to that of the CN Tower, which was not designed until a decade after Wright's death) combined with its tensioned steel frame and the integral character of its structural components would counteract any oscillation. This allows towers to sway substantially in the wind, causing discomfort for occupants of the higher floors. The material used to build tall towers at the time, steel, is quite flexible. It probably would have been possible to erect a self-supporting steel structure of the required height, but there are a number of problems that occur when a building is that tall. At the time, the tallest skyscraper in the world was New York's Empire State Building, at less than a quarter of the height suggested for the Illinois. Wright believed that it would have been technically possible to construct such a building even at the time it was proposed. If built, it would top the list of the tallest buildings in the world by far, being more than four times the height of the Empire State Building, almost twice as tall as the world's current tallest building, the Burj Khalifa and about 2,400 feet (730 m) taller than the planned Jeddah Tower – the latter two both designed by Adrian Smith, whose designs for both buildings are said to have been inspired by that of The Illinois. Wright stated that there would be parking for 15,000 cars and 100 helicopters. The design, intended to be built in Chicago, included 528 stories, with a gross area of 18,460,000 square feet (1,715,000 m 2). The area was a rail yard, then a nine-hole golf course, before Magellan, led by Joel Carlins and James Loewenberg, proposed thousands of homes in the late 1990s.The Mile-High Illinois, Illinois Sky City, or simply The Illinois is a visionary skyscraper that was proposed to be over 1 mile (1,600 m) high, conceived and described by American architect Frank Lloyd Wright in his 1957 book, A Testament. Wacker Drive, and the Coast apartment tower, a Lakeshore East property, at 345 E. The site for the proposed tower is along the Chicago River, east of the Swissotel, at 323 E. The 28-acre Lakeshore East development is roughly bordered by Lake Shore Drive to the east, Michigan Avenue to the west, the Chicago River to the north and Millennium Park to the south. And it could be the world's tallest building designed by a woman-owned firm, as Gang's Aqua Tower was at its opening in 2009. Instead, a Chicago architect would be designing a tower for a Chinese developer on her home turf. If Gang has the job, it would reverse the trend of Chicago exporting its architectural strength in skyscrapers to China. There was speculation Wednesday that Chicago architect Jeanne Gang is the tower's architect, but her firm declined to comment.
