Due to the plannend extension of the tram route that runs from Invalidenstraße to Berlin Central Station the senate administration called out an experts’ review process in cooperation with the BVG (main public transport company of Berlin). The tram station emerged on the northern forecourt of the Central Station Berlin. The roofs of the tram station were designed as constructive shell structures. The concept of a shell structure is the double curvature. This is achieved by up-stations that are located facing the tram tracks and on the outer transversal edges just as low points that are located at the supports. The use of lightweight concrete (LC 45/50) lead to a significant saving of weight. In addition to that the dead weight of the only 7cm thin shell area was decreased by using a non-rusting reinforcement. This construction emphasizes the roofs’ appearance of lightness and is an approach on ressource-saving architecture, as the thin and light construction has a small consumption of raw materials. The new tram station connects the visitors with the city, metaphorically speaking it welcomes the passengers with a waving handkerchief.
