In the construction of the proton medical center at Wuhan Union Hospital, based on BIMforward design, the one-time formation of the comprehensive pipeline design of mechanical and electricalinside concrete can be achieved. The BIM full-professional model can provide support for the zero-collision design between pipelines and reinforcing rebars and the precise positioning of proton medicalequipment. The combination of the independent support technology of comprehensive pipelines and thepositioning technology of simulated wall panels, effectively ensures the precise positioning of mechanicaland electrical pipelines and pipeline accessories inside concrete. By conducting 3D scanning on thepipelines inside concrete, to form visual point cloud data, the end ports of pipelines can be preciselycalibrated, improving the installation accuracy of proton medical equipment.
