The use of BIM helped clarify project Scope to some or all stakeholders involved in at least 3 of the case studies.
Most of the benefits were seen coming from the 3D visualization capacity of implementing BIM. This is probably one of the reasons this was not mentioned more often, since traditional 3D modelling tools not using BIM processes already help on scope clarification. It is relevant though to note that no negative effects were mentioned in any of the projects.
