BIM-Based Collaborative Building Process Management

Today, perhaps more than ever before, a technological revolution can modify the building sector in all its single aspects, greatly affecting services, production, supplies. Freehand drawing, drafting machines or CAD have represented innovative tools in graphic representations. In such cases, the evolution of tools for the productivity of the sector has improved and quickened the actual design, but nothing more.With BIM, instead, the innovation of tools has entailed a methodological innovation for the whole sector, owing to virtual reality simulations, and not only to graphic representations. Several basic principles and their various evolutions worldwide can help understand the BIM phenomenon in order to achieve its mature use.
