Standing tall above
every other skyscraper in Chicago, Willis Tower (formerly known as the Sears
Tower) is a 110-story building in the heart of downtown.
In 1969, Sears Roebuck and Company was the largest retailer
in the world, with about 350,000 employees. Deciding it needed a central office
space for its many employees, the company hired architects Skidmore, Owings and
Merrill to design what would become one of the largest office buildings in the
world. After breaking ground in 1970, it took three years to complete and used
enough concrete to make an eight-lane, five-mile-long highway. The last beam
put in place was commemorated by the signatures of 12,000 construction workers,
Sears employees, and Chicagoans.
In 1988, Sears Roebuck and Company sold and moved out of
the building, but the Sears Tower name remained the same. It was
renamed Willis Tower in 2009 after the Willis Group Holdings, the global
insurance broker who calls the Tower its Midwest home.
In July 2009, U.S. Equities led the design and
construction of a multi-million dollar renovation of Skydeck Chicago, including
the development of The Ledge, a series of glass bays on the 103rd floor that
extend from the building providing visitors with unobstructed views of Chicago
through the windows and glass floors – 1,353 feet straight down. In addition to
The Ledge, the new Skydeck visitor center features museum-quality interactive
exhibits. The opening of The Ledge has provided the Skydeck with
record-breaking visitor counts consistently since its debut.
In May 2011, Skydeck Chicago opened Skydeck Marketplace, a
brand new, 7,500 square foot retail and express cafe experience. Visitors
can purchase their choice of over 300 unique Chicago, Ledge and Willis Tower
items and are treated to authentic Chicago food and beverages including
Connie's Pizza, Eli's Cheesecake and Vienna Hot Dogs.
