Strumenti BIM e GIS per la gestione della manutenzione e salvaguardia della Fortezza veneziana di Bergamo

The implementation of architectural heritages' information systems to collect a huge amount of data using BIM and GIS constitutes a relatively recent field of research. However, the potentiality of such an approach is clear: the systemic application of these tools to the sites belonging to the UNESCO World Heritage would allow the building of easily accessible databases to support the heritage sites' management and preservation. As part of the collaboration between the Municipality and the University of Bergamo, an information system has been designed to support the Preservation Program of the Venetian Fortress of Bergamo. The geometrical simplicity of its elements makes the complex a suitable case study for the development of a data digitization procedure, allowing an efficient management of ordinary maintenance and, where needed, a detailed representation of the state of conserva- tion, structural instabilities, and stratigraphic relationships, which can also be proposed in other contexts.
