Abstract: Intelligent construction management of gymnasium steel structure based on BIM technology is studied in this paper.Through three-dimensional fine model creation, model link integration, roaming detection, construction simulation, numerical simulation, project collaborative management, VR+quality information traceability and three-dimensional visualization technology to guide the construction site, it is shown that BIM technology can effectively guide the construction of steel structure site, improve construction efficiency and safety, avoid waste and rework, and save costs.It is of great significance.
