When was the ledge added to the sears tower

Berglund provided construction services for the installation of the new Sky Deck Ledge at the Willis Tower. Offering views down 1, feet, each of the pods has five sides hanging from steel trusses that project them outward to create the illusion of walking on air. Not one elevator at Willis Tower could transport The Ledge's 1,pound tempered glass panels from the loading dock to the rd floor of Willis Tower.

Each box is constructed of three layers of half-inch thick glass laminated into one seamless unit. So we transported the glass pieces up the freight elevators to the th floor. Then we carefully transferred them, placing the panels on top of elevator cars that reached the rd floor and unloaded them at the final destination.

Meanwhile, new structural steel was added at the rd floor ceiling level to support the glass, and the curtain-wall system was modified using the building's window washing scaffold system. Once the structure was in place, we installed new glass boxes onto a track supported by the new steel. New gaskets were installed to provide a seal around the framing. With this system in place, the boxes were extended and retracted 4 feet 4 inches from the building.

Combined with The Ledge, the Skydeck Chicago experience will provide visitors from all over the world an encompassing view of the building and the city. Each glass box is comprised of three layers of glass laminated into one seamless unit.

The low-iron, clear glass 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.
