3D modelling/BIM

3D modelling/BIM provides possibilities for coordinating and streamlining planning and project work through communication, solution optimisation and quality assurance methods, and engineering controls.

3D modelling/BIM provides possibilities for coordinating and streamlining planning and project work through communication, solution optimisation and quality assurance methods, and engineering controls.

Bane NOR’s Group Executive Management has implemented a BIM strategy which applies the following requirements to contractors:

  1. Model-based methods and tools must be used for the planning, design and construction of all railway infrastructure projects.
  2. "As built" documentation of completed projects must be model-based. Consultants, suppliers and contractors require model-based documentation. Bane NOR will own the rights to all project data throughout the process. It should also be possible to use the models or data for future operation and maintenance of the railway infrastructure.

This means that the model will be used to carry out collision controls and inspection of structures. Arrangements will be made for interdisciplinary simultaneous engineering and co-locations of engineering resources. The BIM strategy is based on the concept of using 3D models instead of traditional 2D drawings and tables. During the construction phase, the model is to be available at the construction site and is to be actively used for monitoring quality, quantity control, progress and communication. Good communication, with tools for revision audits and follow-up by client, progress and cost-development, automated data transfer for staking out and direct computer control, and phase implementation will help reduce misunderstandings and errors. Follow-up tools where the construction work is documented and inspected over the course of the project ensures MOM and final documentation. An as-built model contains all the necessary information regarding the finished construction project, and forms the basis for future operations and maintenance systems.
