The Role of Knowledge-Based Information on BIM for Built Heritage (original) (raw)

Information about historic buildings is extensive and fundamental for maintenance, preservation, and restoration purposes. However, a common problem is lack of standardization and documentation updating. This work aims to gather 3D BIM model of historic buildings with their knowledge-base through a formal ontology. A terrestrial laser scanner was used to collect geometrical data. The resulted point cloud was delimited by Regions of Interest (ROI) then downsized and segmented. The selected case study is the Ballroom, part of the Pampulha Architectural Ensemble designed by the renowned architect Oscar Niemeyer. This building, located in Belo Horizonte, Brazil, has a unique, sinuous and irregular shape, recently listed as World Heritage site by UNESCO, rising its documentation importance both locally and worldwide. The CIDOC-CRM (International Committee for Documentation-Conceptual Reference Model) and FRBRoo (Functional Requirements for Bibliographic Records-object oriented) is the source for create the building ontology, later connected to the model. The proposed methodology shows that linking geometric and semantic database into a BIM environment can improve heritage documentation.
