4. Historic Building Information Modeling (HBIM) and Common Data Environment: The Case Study of Palazzo Vitelli in San Giacomo in Città di Castello

This paper represents an attempt to illustrate HBIM (Historic Building Information Modelling) to support the management of historic buildings, with particular attention to the methods of organising and sharing information from a public administration perspective. Within the framework of a research agreement between the Faculty of Civil and Environmental Engineering of the University of Perugia and the Municipality of Città di Castello (PG), it was decided to carry out a case study on Palazzo Vitelli in San Giacomo, a sixteenth century building. The aim is to provide the Municipality with a BIM model of the building and to support them in the digitization processes, completely from an information technology point of view and embedded in a valid data exchange and management system. The BIM modelling of historical architecture is an opportunity to reflect on the potential of this logic and to address the numerous problems related to the complexity of the historical-architectural heritage. Moreover, the comparison with a context of modest possibilities presents the challenge of adapting structures for sharing information created for different purposes to the BIM, revealing that in many cases the transition to new forms of data management must be made in the spirit of continuity and intelligent use of resources.
