La struttura dei processi HBIM tra rilievo e modello. Scomposizione e ri-costruzione del patrimonio architettonico

Digital models have now become indispensable for all the activities that aim to the knowledge, documentation and planning of interventions on the existing architectural heritage. Currently, 3D modeling and data sharing allow to describe architectural structures as a complex process, based on geometric, cultural, historical, theoretical features, able to extend the knowledge of architectural assets. HBIM (Heritage Building Information Modeling) enrich the management of the existing reality and the design of interventions from the general to the detailed scale, through the complete interaction among different professional figures involved. This research aims to define the main critical issues of the HBIM in relation to the built heritage, trying to define its implications with the representation and optimizing the use of data obtained from the consolidated integrated survey operations. The focus is identifying the decomposition of the architecture, based on structured criteria, and its reconstruction, through ideal models, as the main moments in the HBIM process. The analysis of historical buildings belonging to different historical periods and with different formal and typological characteristics offers the opportunity to test the structure of the process, validating it and guaranteeing quality in all its phases.
