“…As far as survey is concerned, nowadays workflows and techniques are well established [11,28,29], and guidelines such as the English Heritage Metric Survey Practice [30] and Historic American Building Surveys (HABS) [31] are progressively appearing. Open research topics are big survey datasets management [32,33], multi-resolution surveys [34], and automatic point cloud segmentation [35][36][37]. Three-dimensional modeling research concentrates mainly on how to parameterize complex elements (such as ornaments and classical orders elements) [21,38,39] and how to model geometric irregularities and structure deformations [24,40].…”

HBIM for Conservation: A New Proposal for Information Modeling

2019

Thanks to its capability of archiving and organizing all the information about a building, HBIM (Historical Building Information Modeling) is considered a promising resource for planned conservation of historical assets. However, its usage remains limited and scarcely adopted by the subjects in charge of conservation, mainly because of its rather complex 3D modeling requirements and a lack of shared regulatory references and guidelines as far as semantic data are concerned. In this study, we developed an HBIM methodology to support documentation, management, and planned conservation of historic buildings, with particular focus on non-geometric information: organized and coordinated storage and management of historical data, easy analysis and query, time management, flexibility, user-friendliness, and information sharing. The system is based on a standalone specific-designed database linked to the 3D model of the asset, built with BIM software, and it is highly adaptable to different assets. The database is accessible both with a developed desktop application, which acts as a plug-in for the BIM software, and through a web interface, implemented to ensure data sharing and easy usability by skilled and unskilled users. The paper describes in detail the implemented system, passing by semantic breaking down of the building, database design, as well as system architecture and capabilities. Two case studies, the Cathedral of Parma and Ducal Palace of Mantua (Italy), are then presented to show the results of the system’s application.

“…Recently, HBIM modeling from mesh draws attention, and several works have mentioned the possibility to create HBIM models from surface mesh and solid geometry instead of point clouds. Some have converted the solid mesh into 3D solid primitives and then assembled these components to the HBIM model directly in the BIM software [35,41,42]. In [43], HBIM is constructed with three types of primitives and data sources, including point clouds, closed mesh, and CAD/.3dm components.…”

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.

“…When point clouds from a survey performed with geomatic techniques are available, whose use is not natively included among the modelling tools of the BIM software, different workflows (Scan-to-BIM) have been proposed for attempting to extract automatically or semi-automatically the desired features (Wang et al, 2019), in particular for modelling the irregular geometry of historical buildings. Many BIM software can display point clouds for visual reference (Macher et al, 2017), other workflows involve the importation of mesh (Yang et al 2018) or NURBS geometries (Brumana et al, 2018 andKorumaz et al 2017) generated in other software. A smaller number of studies concern the use of BIM models of existing and historical buildings, in particular for building conservation and management activities (Joblot et al, 2017;Bitelli et al, 2017;Bruno et al, 2018;Rodrigues et al, 2019).…”

The paper discusses the first outcomes of an ongoing research activity aimed at developing a general BIM-based methodology for the organization and the management of the information needed for maintenance and safety assessment of museums. The Galleria dell'Accademia di Firenze (Florence, Italy) which has a very complex spatial organisation as a result of transformations occurred over the centuries, has been considered as an illustrative application of the proposed methodology. One of the specific elements which characterize museums, compared to other buildings, is the issue of the relationship between the building itself and the artworks there contained. A specific element of the research is consequently the need not to limit the attention to only the building (i.e. the envelope), but to consider within the BIM also the presence of the art collections. Starting from a recent laser scanner survey, a BIM has been created and a semi-automatic workflow has been investigated to obtain a FE (Finite Element) model to be employed for static and dynamic structural analysis purposes. Currently, since the scans inevitably included the artworks, a test is underway to add in the BIM of the museum also its collections (M-BIM). Each element can be inserted as a BIM object including its geometric representation and physical data (dimensions, materials, weight…) and linked to different museum inventory and conservation databases for the museum management.
