BIM planning for cabling systems for construction of a new Bözberg tunnel

Project overview

In order to ease freight traffic through the Alps, SBB (Swiss Federal Railways) is increasing the size of the Gotthard axis to a 4-metre corridor. This will allow semitrailers with a height of 4 metres to be transported by rail. Because the existing, twin-track Bözberg tunnel is not suitable for the planned 4-metre corridor, a new 2.7 km twin-track tunnel tube needed to be built. As part of a BIM pilot project, Basler & Hofmann modelled cable paths for traction current and telecommunications systems for the entire tunnel. Database-controlled parametric algorithms were used to model the cables and elements of the operating and safety equipment (OSE) at the control centres and in the tunnel.
