Research On Code Compliance Checking For Design Drawings Of Architecture Based On IFC And Ontology

Design drawings of architecture are the main files produced during the architectural design phase and play an important role in the construction guidance and building quality.To control the quality of design drawings and strengthen the supervision and management of construction project design,China has implemented a design drawing checking system.However,against the background of the continuous and rapid development of Chinese construction industry,there are some problems in the manual code compliance checking for design drawings of architecture,such as inadvertent and erroneous checking.This thesis considers the application trend of BIM(Building Information Modeling)in Chinese construction industry,and studies the code compliance checking for design drawings of architecture based on IFC(Industry Foundation Classes)and ontology.This study can be used to assist in the current manual code compliance checking for design drawings of architecture,reduce the workload of the reviewers,improve the efficiency of the checking work and avoid the appearance of the omissions and errors in the checking work to a certain extent.Firstly,this thesis has proposed an ontology-based architectural design specification knowledge modeling method based on advantages of ontology in terms of knowledge representation and semantic integration.Through the analysis of architectural design specifications,the architectural design specification ontology has been developed to realize the semantic expression of architectural design specification knowledge.Secondly,based on the architectural design specification ontology,this thesis has extracted the specific types of architectural design specification knowledge from the architectural design specification files through text processing and type judgment.The extracted specification knowledge can be used to construct SPARQL(SPARQL Protocol and RDF Query Language)checking rules based on correspondence relation and manual improvement.Thirdly,this thesis has studied the description mechanism of building information in the IFC standard and then designed the extraction algorithm for the checking information in design drawings of architecture.The checking information has been established to the instances of the architectural design specification ontology by means of IFC-ontology transformation and ontology mapping.Finally,this thesis has developed a prototype system of code compliance checking for design drawings of architecture and then used an example to verify the feasibility of the proposed method.
