Abstract: In recent years, as the application of BIM in construction project management continues to deepen, BIM is gradually facing higher requirements in terms of semantics. Semantic enrichment for BIM has gradually become a current research hotspot, but there is still a lack of comprehensive reviews on semantic enrichment for BIM. On the basis of extensive literature research, this paper conducts a comprehensive review of BIM semantic enrichment from two aspects: methods and applications, sorts out the key technologies involved in BIM semantic enrichment research and its application status, analyzes and summarizes existing research.The insufficiency of BIM provides a reference for further research and application of BIM semantic enrichment.
