Hovering roof of the Sky Hall
During the construction of the Sky Hall in the 1950s, the architects chose to have the roof rest on the hinges of slim pillars in the middle of the room. In this way, the engineers created the illusion that the roof was hovering. An original idea and a beautiful showpiece of architecture and engineering, but far from easy, it turned out, to renovate. After three years of calculations and preparations, the renovation of the roof has finally started.
In the coming years, the old transit hall will be refurbished. The renovation of the roof signals the start of the second stage of the renovation. The hovering roof is one of the most famous features of the Sky Hall. When it transpired that the roof no longer met the legal standards and regulations for fire safety, the airport studied how it could retain this iconic look after the renovation.
The engineers at Brussels Airport Company thought up an ingenious solution and developed a construction which would retain the floating appearance.
Using a 700 ton crane, three steel trusses, each 55 metres long and weighting 53.5 tonnes, were inserted into the existing roof. On the northern side façade, an extra truss weighing 20 tonnes will be installed. In addition to the installation of these new constructions, the existing pillars and hinges are also reinforced. In this way, the roof of the Sky Hall will once again be safe, yet retain its authenticity.
