From scan to H-BIM: towards an automated workflow for cultural heritage vulnerability assessment

Abstract:

Originally designed for new buildings, Building Information Modeling (BIM) is increasingly being adapted to existing constructions with a focus on the ‘as-built’. Heritage-BIM (H-BIM) addresses the complex reality of historic structures, characterised by irregular geometries, morphological defects, crack patterns and different materials, as well as fragmented documentation. However, there is a lack of standards and tools tailored for heritage conservation to equip H-BIM models with the typical characteristics of historic structures, exploiting the advantages of BIM in building heritage management. In this context, this study proposes a workflow to semi-automatically transform digital surveys into H-BIM models, enriched with detailed attributes - including structural defects and deterioration indicators - to support vulnerability assessment. With a focus on the conservation status of the monument, the final H-BIM output integrates the results of the vulnerability analysis, providing a comprehensive platform for heritage conservation and restoration planning, while improving data interoperability and decision-making in cultural heritage management. The methodology is applied to the case study of the Roman Arch of San Damiano, in the archaeological Park of Carsulae (Italy), for validation purposes.
