During the service life of the building, equipment and facilities and structural facilities need to be continuously maintained. In traditional operational mode, the design and construction phase of the data often cannot complete reservation to operational stage, often can cause operations on the waste of resources. Therefore, with the BIM technology, we can incorporate the project information in the design and construction process into the BIM 3D data model, and then transfer the model to the unit or third party for the later operation and maintenance management through the network, so as to provide data support for the later operation and maintenance work.
