In the construction industry, information sharing by the building information modeling (BIM) generally relies on the industry foundation classes (IFC) schema, but the latter,s unsatisfactory adaptability and inextensibility restrain the former. To overcome the limitations, the Semantic Web was introduced based on the IFC schema to realize heterogeneous data integration and sharing and further achieve semantic-level information delivery. Firstly, the semantic modeling method was introduced through algorithm analysis and model transformation. Secondly, this method was used to create a semantic model for a two-story steel frame building. Finally, the schema of this model was verified for accuracy of the building information delivery and the transferability of the building semantics. The practicability of the semantic modeling method with IfcOWL ontology was supported by the modeling case. The key factors that restrain this semantic modeling method from empowering building information delivery was explored by analyzing the schema of the element of the semantic model. And introductory ideas about redundant information avoidance, domain ontology development, and lightweight semantic modeling were proposed to fill the gap. The SPARQL query case shows that the parsed schema is effective for avoiding redundant information. Consequently, this method has advantages in sharing and integrating multi-source heterogeneous building information and can effectively improve the intelligent level of building information management.
