HBIM and Fire Prevention in Historical Building Heritage Management

Italy possesses a unique cultural heritage that is constantly under threat from natural and anthropic risks: fire vulnerability is one of the main causes of architectural heritage destruction. The goal of this work is to propose a methodological approach to the management and preservation of historical building heritage with respect to fire safety. This approach aims to facilitate the process of analysis, design and fire management in historical buildings, using automated procedures based on HBIM (Historical BIM) processes. BIM can be used effectively in the digitization of cultural heritage: HBIM enables the three-dimensional modeling of the building by means of parametric objects, to which infographic information is associated, related to an appropriate Level of Development (LoD). A workflow process has been defined to set up a procedure for best practices which can guarantee the correct interoperability between BIM programs and fire safety design. The procedure, based on the exchange of IFC files, shows result applying analysis through Model Checking software of Model Checking and shows limited interoperability with fire safety software. The procedure has been validated through real tests and measurements, by comparing data obtained from a traditional fire prevention analysis with the data gathered from the automated procedure. The real case study is the ?Command Building? of the School of Air Warfare in Florence. Results mainly indicate that fire safety in historical buildings should always be managed using a performance-based approach (interoperability issue between HBIM and fire safety software).
