Abstract: The BIM-based compliance checking of architectural design is of great significance to improve the standardization and accuracy of BIM forward design, as well as to ensure the reliability of BIM submission as design results. Through the introduction of the application of expert system in compliance checking, this paper analyzes the acquisition and expression of knowledge of architectural design codes, establishes the rule base of architectural design codes, and proposes the basic method of BIM information extraction and mapping. On such theory basis, the paper further proposes the basic framework of compliance checking system, and develops the prototype system of BIM-based architecture compliance checking system, whose theorization and feasibility are verified by practical cases. At last, considering the future development of the intelligent system for compliance checking, the paper puts forward some suggestions from two aspects of model delivery standards and specification definition.
