The BIM (building information model) technology is widely applied to the building industry, and provides a borrowed experience for the interaction of three-dimensional design data of power transmission and transformation projects. The data exchange problem is the core problem of the BIM technology, and the method for solving the problem by the BIM is to develop a data standard supporting automatic information exchange among all stages of a project life cycle, all project members and all software products. IFC (engineering data interchange standard) is such an open, structured, object-based information interchange format, which is a similar object-oriented building data model. The IFC model includes information for various aspects of the building throughout its lifecycle. The purpose of the IFC standard is to support the cooperative work of various specific software for the design, construction and operation of buildings, which is currently the most comprehensive and detailed specification for building information description.

Moreover, software systems related to power grid engineering construction are different in technical systems and various in data formats, and most of data at an entrance and an exit only support foreign standards, so that each system has no clear interaction means and data standards, information cannot be shared in time, the phenomenon of 'information isolated island' of engineering data commonly exists, the development of three-dimensional design in power transmission and transformation engineering construction is hindered, and the problem of information interaction among the software systems of the power transmission and transformation engineering becomes very critical.
