Ontology-Based Computerized Representation Method for BIM Model Quality Standards

High-quality BIM model is the premise to ensure the effective application of BIM technology. Thus, many countries and organizations have developed standards to clarify the requirements of BIM model quality on data completeness, consistency, and correctness. However, due to the complexity of BIM model and the professionalism of standards, checking BIM model quality manually is challenging and time-consuming, so it is necessary to develop automatic check systems for BIM model quality. To develop the system, computerized representation of BIM model quality standards is the key and basic step. Towards the objective, this paper proposes an ontology-based computerized representation method for BIM model quality standards. In this method, OWL is applied to represent the concepts and relationships, and SWRL is used for representing BIM model quality rules in the standards. After representing the Chinese BIM model quality standard, a rule base composed of 41 SWRL rules is constructed and the effectiveness of the method is verified. This research contributes to the development of BIM model quality automatic checking system and the promotion of BIM technology.
