The progressive digital transition of the construction sector is now driven by innovative methods and tools based on Building Information Modeling. Updating public administrations in the Italian national context requires the introduction of new skills and professionalism capable of implementing the new paradigm shift. This transformation involves adapting traditional procedural standards to those introduced by technological innovation.

The contribution focuses on the definition of a BIM strategy geared toward the relationship between the regulatory, technological and procedural contexts. The analysis and correlation of the three domains together with the subdivision into specific areas of expertise allowed the identification of an operational methodology applied to cost management to overcome the challenges related to the fifth dimension of BIM (5D BIM). Starting from the identification of model uses defined by the job order, the graphical and alphanumeric contents of a BIM model were explored through the concept of information requirement level.

The proposed approach highlights the importance of interoperability as a connecting bridge between the parametric digital modeling activity and the visualization of the results obtained from the BIM process.
