Abstract:

The manual review of construction plans in the building industry suffers from high repetitiveness, substantial time consumption, and extensive expert resource usage. To improve review efficiency and promote intelligent construction development, an intelligent construction plan review method was proposed, integrating review rule compilation, vector model construction, and image-text recognition to achieve intelligent review of multiple types of plans. The review rules were based on group technical documents and historical review samples, filtered through high-frequency historical review comments and expert judgment, then compiled item by item using regular expression technology. A review model based on semantic similarity comparison was constructed, embedding plan text content into vector space and implementing semantic comparison through vector cosine similarity calculation, thereby enhancing review flexibility and fault tolerance. Additionally, YOLO-based image text recognition technology was incorporated to process textual content in document images, ensuring comprehensive review coverage. Experimental results showed an average review accuracy of 90.4% and an 87.9% improvement in time efficiency compared to manual review. The system can process multiple text format inputs with robust performance, significantly improving review work efficiency and playing an important role in promoting enterprise digital transformation and the popularization of intelligent construction technology. Currently, the platform equipped with this review technology was tested in multiple branches and projects of the group, generating accurate review reports and delivering significant improvement in review efficiency.
