The As-built Building Information Model (BIM) serves as a carrier of lifecycle information for the physical building and is a critical component of project handover. Despite the issuance of numerous delivery standards globally, efficient methods for reviewing information completeness remain insufficient, hindering the timely and effective delivery of project information. To address this gap, this research employs ontology technology as its core to develop a method for reviewing information completeness in as-built architectural engineering BIMs. An ontological model is constructed using Protégé, Semantic Web Rule Language (SWRL) rules for Completeness Review are defined, and a Revit data extraction add-in is developed to store model data in a database and map it to an ontological knowledge base. An integrated review system for As-built BIM information completeness is subsequently built. This system automates the entire review workflow, encompassing data import, semantic conversion, rule-based reasoning, and result output. Validated through a teaching building case study, the system successfully and accurately identified missing attributes and documents within the model, demonstrating high accuracy and review efficiency. The proposed method and its accompanying review system provide a scalable, rule-driven solution for ensuring BIM integrity, effectively supporting digital delivery in the architecture, engineering, and construction (AEC) industry.
