Execution

Within just two weeks, our Digital Rail Services team delivered a comprehensive BIM model for SBB, setting new standards in digital asset capture.

Key features of this project

  • Complete subsurface documentation:
    Not only the visible infrastructure, but also all structures and layers beneath the track bed were captured – including detailed properties of bore cores and geotechnical data.
  • Intelligent data integration
    All information from the Fixed Assets Database (DfA) is directly linked to the 3D geometry. Each object carries its full set of attributes – from mast numbers and construction types to coordinates.
  • Standards & structure:
    The model is based on IFC 4.3 and consistently structured according to SBB’s discipline data catalogue, ensuring seamless integration and interoperability.

 

This type of digital twin enables well-founded planning and implementation of future projects and can be integrated into an asset management system to support improved maintenance planning.
