TOWARDS LINKING VIRTUAL MODELS WITH PHYSICAL OBJECTS IN CONSTRUCTION USING RFID - REVIEW OF ONTOLOGIES

Abstract:Virtual models have in recent years proven their worth in practice relating to building design. Today virtual models of the complete project are created before the project is carried out in practice. The immediate advantages of this are great; it introduces fewer errors, gives a better production basis, improved clarity and enhanced communication methods compared to traditional 2D drafting methods. However, there is still much unutilized potential in the virtual models, especially in the construction and operation phases. It is expected that a digital link between the virtual models and the physical objects in the construction process can improve the information and knowledge handling from design to construction, operation and maintenance. The link can be created by use by use of Radio Frequency Identification (RFID) technology. This paper describes a review and assessment of existing ontologies relevant in relation to creating this link. The ontologies are categorised according to their applicability to specify technical services, resources, organisational relations, business processes and overall frameworks for ontology descriptions and their relations. It is concluded that, with few modifications the technical service and resource ontologies are applicable for industrial use and the meta, organisational and business process ontologies needs further development and industrial maturity to be applicable.
