Digital tools and techniques, also because of the recent restrictions caused by the pandemic, have gained an almost necessary role in human activities. The construction sector, which is structurally slower in metabolising innovation, has a significant productivity gap when compared with manufacturing. This research therefore analyses the management methodologies used today for construction and proposes, through the principles of reactive programming and an integrated use of BIM and IT tools, a tested methodology capable of increasing the productivity and quality of the construction process on building site.
