Architectural Knowledge Modeling: Ontology-Based Modeling of Architectural Topology with the Assistance of an Architectural Case Library
Abstract. BIM applications have gradually replaced CAD software as a means of solving complex information integration problems in different disciplines of AEC industry. As communication platforms for design knowledge, however, most BIM cannot achieve formal representation of architectural design knowledge, especially what are different from engineering and construction. In traditional DBD (design-bid-build) process, architects package knowledge within drawings, which isolates architects’ contributions from engineers, fabricators and constructors. Once the knowledge expressed by drawings is lost after being converted to BIM, it is very difficult for architects to protect their contributions in the decision-making process. When architects cannot explicitly share and validate their knowledge during their negotiations with other disciplines, the BIM-based IPD (integrated project delivery) inevitably causes architects to be marginalized. Based on the initial proposal of Eastman, BIM should be composed of three types of design information: semantic, topology and geometry. Topology of BIM consists of the mathematic connections between components, and functional definitions of parametric modeling, and is the key to the conversion of the three types of architectural design information.
