[en] For the new building of a nuclear power plant, different special technical problems are to be handled with regard to the facade and roof constructions. On the one hand, these are caused by the local climatic conditions, while on the other hand a special demand with regard to operational safety is associated with the new building of a nuclear power plant. The static-construction demands, the requirements from the construction physics and as well as the erection conditions required the further development of established facade structures and their testing in laboratories and testing institutes before production commencement. The already largely realized building envelope of the conventional area - the ''Turbine Island'' - is the subject of this paper. Zueblin Stahlbau GmbH, an IFBS and DStV member, also implemented the steel construction works in the Turbine Island, as well as the facade work. Synergies were generated from the combination of both trade sectors, in particular in the planning of the interfaces and the intermeshing of assembly process sequences on site. In sum, with the Turbine Island, approx. 90000 m² profiled sheet metal units are laid and approx. 4000 tons steel structures mounted. (orig.)
