As construction processes are becoming increasingly complex and varied from the point of view of the actors and systems involved, a modeling like the one proposed by BIM will gradually become more widespread.
In Europe, the European Parliament has already issued a directive in 2014 (Directive 2014/24 / EU) where it clearly expresses the indication to introduce the Building Information Modeling within the Procurement procedures of the Member States.
BIM will soon become the standard process for all public buildings as the directive requires all member states to encourage the use of BIM in their respective countries for publicly funded projects in the European Union as of 2016.
On 1 December 2017, Italy established a decree of the Ministry of Transport (Decree 560 of 01/12/2017) with the methods and times for the gradual introduction of electronic modeling methods and tools for construction and infrastructure also defining the time for the mandatory introduction of these methods, starting from 1 January 2019.
