The glass roof over the Spandau station in Berlin has two regions with different widths; region A has a width of 34 m, and region B with a width of about 56m. The superstructure in both regions of the glass roof is multiple cables stabilised steel grid shells, the roof has multiple arched grid shells. The grid shell structure is supported in the transverse direction of the hall by curved steel girders with a spacing of approx. 18 m in the longitudinal direction of the station, which transfer the loads in the longitudinal direction of the roof to the columns. The design for the construction stage, Dr. Saad was responsible for different construction stages, FE-Model was considered. The internal forces in the different elements in all considered construction stages were calculated and compared with the corresponding value of the end system. A concept for the precise erection of the stabilizing cables and its prestressing level were determined.
