This thesis provides the foundation for a thorough knowledge of Building Information Modeling (BIM) and its applications on virtuality continuum. In particular, it is proposed the development of an innovative prototype for virtual reality simulation, created for the safety training on construction sites. Its structure is organised in three sections. In the first section the attention is drawn to the nowadays reality where BIM is adopted, its applicative models in mobility and cloud systems, thus making clear the concepts of Maturity Levels and Levels of Development (LOD). Then the guidelines about BIM and safety will be analysed, regarding both the Italian context and the international one.
