The Federation Tower will have the tallest steel-glass roof structure in Europe using high-end three-dimensional parametric design tools and advanced modelling software to achieve an integrated design of structure, skin and double-curved geometry.
As a special feature, a movable platform at the 91st floor will serve as a VIP dining area, that is motorized and can be mechanically shifted outwards. Completely integrated in the roof cap façade, the one bay wide section will move out up to three meters providing spectacular views over the city. Additional features as glass roof, glass floor and operable glass side walls will complete the design.
Thornton Tomasetti performed all structural calculations including the glass wall and glass floor design (triple-laminated safety glazing) and provided detailed façade skin drawings with special focus on water-tightness and esthetically aligned joint elements that integrate necessary space for the electrical moving devices.
