From Cognitive Buildings to Digital Twin: The Frontier of Digitalization for the Management of the Built Environment

The BIM holistic approach leads the AEC sector to manage all the different disciplines involved in the construction process. Its nDimensions, indeed, concern geometry, structure, systems (3D), work-site management—also in terms of time and costs—(4D, 5D), safety, energy performances (6D), maintenance and building management (7D). Besides the analysis of the state of the art, the n + 1 dome case study has been used to explain the advantages of BIM, sensitization and digital tool application for both product and asset management (PIM, AIM). Finally, the chapter illustrates the potential of Internet of Things (IoT), Machine Learning (ML) and Artificial Intelligence (AI), moving from Cognitive to Predictive buildings, nowadays conceived as the new perspective of 4.0 construction.
