Nowadays, the BIM methodology represents a real challenge to innovation in the construction world. The development of a multidisciplinary integrated planning and the consequent amount of data is, on the one hand, an obstacle to overcome in managing the workflows and, on the other hand, a goal that Management choices must strive to achieve. This is why we need to merge digital innovation and integrated planning together with the project management world. In this perspective, the PCP (Planning and Project Control) function of the public promoter TELT has recognised the importance of modelling a workflow, even if simplified, capable of integrating, through a time and cost analysis, the design world with that management. The WBS technique on which the project structure is based has allowed the fusion of the data volumes within a composite project, while the interoperability and information sharing analysis have highlighted which critical issues need to be overcome in order to fully implement the BIM methodology.
