BIM technology and VR have the ability to innovate the building industry. At a first perspective, many feel the benefits of using a BIM model with VR are only for improving the 3D model for visual aids, but taking a second perception at a BIM model it reveals diverse reasons to adopt BIM with VR. Collaboration in VR can be the future of VR BIM. The fundamental base of BIM + VR concerns the collaboration as a first step, but the possibility of consult data while walking through the building, improves significantly the use of BIM in design, construction, maintenance, and management. Introducing VR interactive capabilities into 3D/BIM models in the construction process is a main way to test virtually and correct a construction project before the realization, as the walkthrough is available as well the visualization of data linked to each parametric object, improving the necessity collaboration within the design team. So, BIM/VR applications can contribute to reduce costs due to the construction of a real mock-up, and to avoid mistakes on site that generates material wastes.
