Early in the project, it was decided that the project will be conducted using BIM methodolgy, and that all the objects will be modeled in 3D. The bridge geometry is complicated, as it needed to fit to the existing terrain and the planned road. Therefore, the biggest challenges for the design were connected with creating a complex BIM model and included:

• Complicated geometry of the bridge
• A huge number of prestressed cables in the bridge deck
• Time-consuming modeling of reinforcement
• Handling of revisions
• Designers working in different countries
• Quality assurance of a BIM model
