BIM Model Integration of Concrete and Steel Structures in Assembled Substations

摘要

Application of BIM technology in the construction of assembly substation is the trend of construction industrialization and informatization in power grid industry. Assembled substation is composed of concrete structure and steel structure. In the process of building refined BIM model, two different models built by Revit and Tekla are integrated into Navisworks through IFC data exchange format. The results show that when Tekla model exports IFC files, the Coordination View 1.0 or Surface geometry format is selected to maintain the integrity of the model imported into Revit; Revit model is exported to *.nwc format, and model in Tekla is exported to IFC format, which can be imported into Navisworks for integration model and using. According to the characteristics of assembled substation, the efficiency and fineness of BIM model can be significantly improved by using a variety of software hybrid modeling methods.
