Ohranjanje in monitoring objektov kulturne dediščine z HBIM

Building Information Modelling (BIM) asset management´s capabilities are currently extending into heritage conservation through Historical/Heritage BIM (HBIM). This work explores HBIM’s potential for supporting the diagnosis and maintenance phases of historical structures in heritage contexts. We propose a methodology which pairs mesh geometry with a high Level of Information (LoI) and apply them in Ljubljana’s Roman Wall, as a case study. It focuses on an HBIM model creation by bringing real world geometry into Industry Foundation Classes (IFC), via a Scan-to-MesHBIM workflow. These mesh entities are segmented into smaller IFC elements (i.e., IfcWall) and semantically enriched with linked data such as material, diagnosis, and previous tests, stored as off-file metadata and exposed via ontologies. This approach can thus be seen as turning the page towards the future IFC5 standard, which will allow mesh1 and texture2 to be properly handled by IFC. We also propose an openBIM methodology to interact with this information by deploying it on a common environment: a server running webIFC. We argue that this is the future of IFC collaboration: online, permissionless and software agnostic.
