The Sofitel high-rise building in Vienna, designed by the renowned architect Jean Nouvel, represents an architectural highlight. The 13-story tower floats above a 30-meter-high and 27-meter-wide air space.
Zeman & Co developed an innovative method where two load-bearing floors were pre-assembled at ground level and then hydraulically lifted to their final position at a height of 30 meters. The steel structure serves as the main supporting system, integrated into the walls, ensuring a stable connection between the lower and upper floors. The entire construction was completed within a tight timeframe, with Zeman & Co handling the planning, production, and assembly of the 1,400-ton steel structure. Special attention was given to the connection between the steel and concrete structures, which posed significant challenges due to their different stiffnesses.
