ART'23 14th International Conference on non destructive investigations and microanalysis for the diagnostics and conservation of cultural and environmental heritage

The BIM (Building Information Modeling) approach to the construction sector is now well-established, both theoretically and practically, thanks to a legislation that encourages the use of such systems. In line with international trends, DM n. 560 of December 1, 2017 (as amended by DM n. 312 of August 2, 2022) envisions the mandatory use of BIM for public interventions, defining a road map based on the total amount of public works from 2022 on. This logic encompasses all interventions, including restructurings and restorations, which account for a significant portion of the Italian building sector. This contribution proposes an experimental application on the church of Sant’Agata in Brescia, where an ongoing structural monitoring process has been activated, and a series of non-destructive investigations were conducted on the main roof structure. The numerous collected data denounce an evident malaise of the building and they are functional for the development of the restoration project. The accessibility of the analysis’ results and the need to coordinate many different professional figures, as frequently happens in case of restoration projects, has suggested the study of an HBIM model supporting the design activity, the knowledge management process and the planned future conservation practice. The procedure has implied a preliminary evaluation about the type of available information and then unconventional modeling solutions have been identified on the basis of the BIM available tools, creating a flexible and dynamic model, that offers the possibility of implementing and coordinating the data over time.
