During the project preparation, checks for model collisions and discrepancies are performed cyclically. These checks are carried out by the project participants, the BIM coordinator, and the BIM manager within certain limits of responsibility:

• Designers perform the collision check in the scope of their design part using the reference model method, loading the models of other project participants, and modeling their own components.
• BIM coordinators may carry out visual inspections to verify whether team models are compliant with the norms: file names, project starting point co-ordination, a specific supervised part of the project information compliance requirements (LOIN matrix), etc.
• The BIM manager checks the collisions of all submitted parts and the compliance of the whole project.

The checks are performed in several ways:

• Visual viewing of models.
• Using special tools for collision checking.
