The BIM can achieve the accurate modeling of the curtain wall design. Through BIM technology, designers can conduct three-dimensional modeling of the various components, materials and systems of the curtain wall, including the curtain wall panels, glass, aluminum alloy profiles, connecting parts and so on. This enables designers to more accurately understand and grasp the overall structure and details of the curtain wall, and improve the accuracy and reliability of the design. The BIM can conduct collision detection and conflict resolution of curtain walls. In the curtain wall system, there may be conflict and interference problems between multiple components such as curtain wall plate, glass and structure. Through BIM technology, the collision detection of the curtain wall model can be conducted, that is, the conflicts between various components can be analyzed, and the problems can be found and solved in time to ensure the design and construction quality of the curtain wall. The BIM can also support the optimization and coordination of the curtain wall construction process. Through the BIM model, the construction team can simulate the curtain wall construction process, formulate a reasonable construction plan and process arrangement, and improve the construction efficiency and quality. At the same time, BIM also provides a multi-party collaboration platform, in which all relevant parties can cooperate in real time and share information to ensure the smooth construction process. BIM also plays the role of later maintenance and management in the deepening of curtain wall specialty. By integrating the BIM model with the information system such as the equipment monitoring system, the remote monitoring, fault detection and maintenance management of the curtain wall can be realized, and the operability and sustainability of the curtain wall can be improved.
