For the IWES in Bremerhaven the work planning for the steel construction and the ETFE membrane surfaces of the curtain wall was prepared. For this purpose, the CAD planning of 380 steel consoles was individually created on the basis of an allowance on the concreted weld-on plates with the help of a tool created for this purpose. Between the support layers attached to the brackets, a presented single glazing and a mechanically pre-stressed ETFE foil alternate, which allows for shading and ventilation of the offices even in strong winds.
