CHICAGO, IL.- Sears Tower
presented The Ledge, a series of glass bays that extend from the building, debuted to the public as part of an updated Skydeck Chicago experience. Reaching out 4.3 feet from the buildings Skydeck on the 103rd floor, visitors have unobstructed views of Chicago 1,353 feet straight down.
Weve listened to our visitors and people just want to get closer, said Randy Stancik, general manager, Skydeck Chicago. Youd only need to see the forehead prints on the windows to know that visitors are constantly trying to catch a glimpse below. Now, they have an unobstructed view straight down and an exhilarating experience.
The Chicago office of Skidmore, Owings and Merrill (SOM), the buildings original designers, provided an innovative plan for this architectural and engineering achievement. SOM designed The Ledge so that the fully enclosed glass boxes rest between conveyer belts. The boxes retract into the building, allowing easy access for cleaning and maintenance. Extending from the towers west side, each box can accommodate four to five people at a time, with unobstructed views of people, taxis and bridges over Wacker Drive and the Chicago River.
The Sears Tower set architectural and engineering standards when it was first built and now we were able to carefully craft new elements that expand the capabilities of the original design while retaining its integrity, said Ross Wimer, design partner, SOM.
The Sears Tower has always been about innovation. For this new Skydeck experience, we have kept with that tradition. Cantilevering out from the side of Americas tallest building, the viewing platform allows visitors to experience the incredible city of Chicago literally beneath their feet. This is a great addition to the Sears Tower and to Chicago, added Bill Baker, structural engineer partner, SOM.
An unmatched view is not all that Skydeck Chicago offers. From the moment visitors arrive, they will enjoy new interactive and educational museum-quality exhibits. The exhibits highlight the iconic landmark, and celebrate Chicagos sports, architecture, pop-culture, history, food, music and people. Interactive displays feature the citys rich history, major Chicago attractions and fun facts.
The multi-media elevator gives visitors one of the fastest rides in the world up more than one hundred flights, while giving visitors points of reference for the heights they are ascending along their journey to the 103rd floor. Design and branding firm Hornall Anderson developed the visitor experience to showcase the towers story as both a Chicago and global icon. Combined with The Ledge, the Skydeck Chicago experience provides visitors from all over the world an encompassing view of the building and the city.
The Skydeck attracts more than 1.3 million visitors annually who enjoy views of up to 50 miles and four states, Stancik said. Now, visitors will be taken on a one stop Chicago journey from the buildings inception and role in Chicago, to the daring experience that awaits them on The Ledge. In a single trip up to 103, visitors see and learn about the best that Windy City has to offer.
MTH Industries, the Chicago-based 120-year-old glass and architectural metal contractor that installed Cloud Gate in Millennium Park, installed The Ledges glass panels. Each glass box is comprised of three layers of glass laminated into one seamless unit. The low-iron, clear glass is clear is fully tempered and heat-soaked for durability. In addition, the motorized system that projects and retracts the boxes from the building utilizes steel LinearBeams.
