One World Trade Center, New York, NY USA

GBL provided rail-riding Work Platforms with adjacent material hoists at each face of this iconic new supertall’s 185 foot high base. This “strongest office building ever built” utilizes an exterior cladding system with operable glass fins which covers a muscular concrete and steel base. The base façade’s “third dimension”, created when the glass fins are fully open, dictated that each independent rig be designed with an ability to be powered in all six directions: in, out, up, down, back, and forth. The dual material hoists were designed to alternatingly align with the Work Platform to deliver panels to opposite sides of its integral front monorail, while the platform’s upper tier was designed to allow a monorail-suspended panel to pass between the platform’s inner rails and the face of the building. With a capacity of up to six workers on each two-tier platform, including a heavy curtainwall panel on the front monorail, maximum comfort and ease of use during all phases of the installation process were guaranteed.
