At present, the application of domestic BIM technology is basically concentrated on the integration of three-dimensional visualization of buildings, progress simulation and comprehensive arrangement of pipes. In order to further explore the in-depth application of BIM technology in the fields of traditional construction engineering, restoration of ancient buildings and 3D printing, this paper integrates key information such as 3D scanning, progress simulation, load debugging, business management and control, and refined management through the BIM model to help the construction process perform simulation to provide core data in time such as accurate resource consumption, technical requirements, and other important links in the construction process such as materials, business, schedule, production, etc, and to improve communication and decision-making efficiency, thereby saving time and costs and improving project management quality.
