Instead of the usual reinforced concrete construction, the building has been designed as a pure steel structure which consists of three independent parts, i.e. the membrane façade, the modular stadium itself and the interior roof. In order to be able to put up a building of the size of a football stadium in just a few months, design and construction proceed in parallel. An important tool in this complex process is the detailed visualisation of the entire work schedule: it covers and displays each step in chronological order in weekly sequences. A prerequisite for the success of this novel working method is the extensive experience in design, management and construction scheduling provided by the consortium, as well as very good communication between the design team and the construction companies.
