BIM model data is an important component of urban data assets, and reasonable construction of BIM model quality evaluation system is an important guarantee of BIM model data quality. This paper takes BIM models in the scheme design stage of Xiongan New Area in many professional fields, e.g. architecture, road traffic, municipal pipeline and utility tunnel, as the main evaluation object, and discusses the characteristics and applicability of computer automatic judgment and manual judgment. The paper further discusses BIM model quality evaluation index system centering on six dimensions, i.e. model integrity, model normalization, model correctness, model attribute consistency, model collision and spatial consistency. Finally, the method proposed in the paper is successfully implemented and verified in the model quality inspection of Xiongan New Area.
