By using BIM technology and building BIM models of various professions, designers can easily find collision conflicts in the design under the virtual three-dimensional environment, which greatly improves the design ability and work efficiency of pipeline synthesis. This not only eliminates the collision conflicts that may occur in the construction process of the project in time, but also significantly reduces the resulting change application forms, improves the production efficiency of the construction site, and reduces the cost growth and delay caused by the construction coordination.
