HBIM Modeling from the Surface Mesh and Its Extended Capability of Knowledge Representation

Abstract

Built heritage has been documented by reality-based modeling for geometric description and by ontology for knowledge management. The current challenge still involves the extraction of geometric primitives and the establishment of their connection to heterogeneous knowledge. As a recently developed 3D information modeling environment, building information modeling (BIM) entails both graphical and non-graphical aspects of the entire building, which has been increasingly applied to heritage documentation and generates a new issue of heritage/historic BIM (HBIM). However, HBIM needs to additionally deal with the heterogeneity of geometric shape and semantic knowledge of the heritage object. This paper developed a new mesh-to-HBIM modeling workflow and an integrated BIM management system to connect HBIM elements and historical knowledge. Using the St-Pierre-le-Jeune Church, Strasbourg, France as a case study, this project employs Autodesk Revit as a BIM environment and Dynamo, a built-in visual programming tool of Revit, to extend the new HBIM functions. The mesh-to-HBIM process segments the surface mesh, thickens the triangle mesh to 3D volume, and transfers the primitives to BIM elements. The obtained HBIM is then converted to the ontology model to enrich the heterogeneous knowledge. Finally, HBIM geometric elements and ontology semantic knowledge is joined in a unified BIM environment. By extending the capability of the BIM platform, the HBIM modeling process can be conducted in a time-saving way, and the obtained HBIM is a semantic model with object-oriented knowledge.

Networking Historic Environmental Standards to Address Modern Challenges for Sustainable Conservation in HBIM

“…However, the work largely deploys classes established by the CIDOC Conceptual Reference Model as opposed to the more relevant architectural classification system of architectural specification suggested in respect to this research [49]. Xiucheng et al have sought to combine HBIM data developed in REVIT™IFC files with Semantic Ontologies set out in Protégé by defining unique identifiers to link them [50]. Using CIDOC CRM identifiers to build ontologies on a standardised platform, they finally propose the extension of REVIT™ using Dynamo to augment segmented models Appl.…”

From Point Cloud Data to Building Information Modelling: An Automatic Parametric Workflow for Heritage

“…Barazzetti et al [47] considered a semi-automatic approach, as it required successive steps to reach editable parametric objects starting from non-uniform rational B-splines (NURBS) and converted into solids. Recent work [48] developed a new workflow for mesh modelling towards HBIM, for which Autodesk Revit (BIM) and Dynamo are used to explore new HBIM features. However, several studies [49,50] implement these tools for specific objects, but not for building construction units.…”

HBIM for Conservation: A New Proposal for Information Modeling

“…It became the ISO standard in 2006, and provides definitions and formal structure for representing information used in CH documentation. While developed mainly to support cataloguing and museum documentation, in recent years it has also been applied in the BIM environment as described, for example, in Pauwels et al [48], Yang et al [49], and Acierno et al [50,51], who extend the CIDOC-CRM model to the entire field of architectural heritage and its conservation process.…”
