The project explored in this paper has a large number of individual units, covers a large area, and involves multiple disciplines. Through the creation and integration of refined models, full professional collaborative work is carried out before construction to avoid potential collision between multiple disciplines and sections in advance. After the modeling and drawing, technical disclosure and guide on-site construction are conducted. Through inspection, rectification, review, and summary, this paper has achieved a closed-loop management of formwork construction management. As for deepening design management, construction process management, and cost management, this paper elaborates on the specific application innovation and practice of BIM technology in airport project construction management, and analyzes the application effectiveness of BIM technology in construction management.
