Dynamic model of implementation efficiency of Building Information Modelling (BIM) in relation to the complexity of buildings and the level of their safety

The aim of the work is to present the efficiency of the establishment BIM into the building industry on the created dynamical model related to the extent to the complexity of buildings, in which Building Information Modeling (BIM) has been used as, a tool of the industry revolution 4.0 in the CZE. The work shows the rank of the influence in establishment of new technologies 4.0 and Internet issues on increasing demands and complexity of buildings and their safety. A result of simulation in the dynamical model emerges the conclusion why we should be interested in the rise of the complexity extent of processes of the buildings in relation to corresponding cost of BIM. It shows that the establishment of BIM achieves the necessary extent of the efficiency, i.e. in what assumptions and parameters the significant reduction of the direct or indirect costs has been achieved in the construction, management of the buildings and the facilities in their life cycle.
