Towards the creation of an Open Source HBIM tool for planning diagnostic and restoration activities: the example of the Troia Cathedral rose window

The aim of this work is to set up an HBIM (Heritage Building Information Model) system to facilitate the planning of diagnostic and restoration activities by bringing all archive information into a digital platform, accompanied by three-dimensional models that can be consulted and examined. Frequently, in case of ancient buildings, reconstruct the complete history of the property is not possible, due to a lack of accessible sources. The creation of the HBIM digital tool for consulting the architectural artefact and related information was only the last phase of this work, which began with: (i) Acquisition of archive sources in order to reconstruct the history of the restoration and renovation work on the monument; (ii) Acquisition of information about the diagnostic analyses previously carried out on the monument; (iii) acquisition of data useful for the creation of a digital twin.
