In the future, the Arnulfsteg Bridge, which is approximately 242 m long, 3.50 m high and made of steel, will cross the 37-track railway line of the city. Construction company, Mayerhofer, turned to Doka for formwork planning for the south ramp, including the seven ramp supports and one stairway support. Both the loop-shaped ramp belt and the props had extreme technical demands.
In order to get a better idea of the formwork planning, Doka prepared it in such a way that the foreman and project manager were able to virtually go through the subsequent assembly 1:1 in advance using VR glasses. The two agree that, "It'll give you a whole different feel for the construction site." This also takes planning technology to a completely different level: For example, in the rounding area of the ramp, it became apparent that it would have taken a great deal of time to measure the originally planned formwork variant on site. Instead, Doka proposed an alternative, with higher manufacturing requirements in advance, so that a lot of time could be saved on the construction site itself. “After visualising the situation I was able to compare both options and it was plain to see: it works out better with the prefabricated boxes”, says the foreman. Visualisation also improved the geometry of the three-armed prop.
