In response to the complex construction content and inconsistent construction progress of various trades in electrical substations, this article uses LiDAR point cloud technology to achieve rapid modeling of substations and transmission lines. With the help of post-processing technology from Unity 3D engine, a BIM model that can be used for substation roaming inspection and construction design is constructed. At the same time, a substation collaborative construction detection system was developed, which coordinated the progress of collaborative construction operations for different types of work, providing support for rapid construction and early planning of substations.
