BSDD TO DOCUMENT STATE OF PRESERVATION OF ARCHITECTURAL HERITAGE IN OPEN-HBIM SYSTEMS
Keywords: bSDD, HBIM, State of Preservation, architectural decay, open-BIM
Abstract. This research explores the possibility of structuring an OpenBIM process useful to work in the BIM ecosystem also for cultural heritage and historical architecture, independent of any specific software and overcoming the difficulties arising from the unique characteristics of these artefacts. The main focus of this work is the use of bSDD as a methodology to add specific information on state of preservation of surfaces and materials directly to BIM models, making it shareable and readable in any IFC viewer.
The complexity of historical architecture and the importance of information about its conservation status, puts higher requirements on the level of development of (H)BIM models and its possibility to realize a better interoperability among multiple disciplines and different software solution.
To date, there is still no single, recognised, and accepted solution that allows information on the state of preservation of historical artefacts to be documented in BIM according to shared and open workflows. In this respect, the research proposes an ordered organisation - with the use of bSDD - of all decay information present in thesauri, vocabularies, ontologies and official regulations, making it possible to use it according to a predefined process.
The testing operation used as a case study Villa Matarazzo, a historic house located in Ercolano (Naples, Italy).
