With the tide of Smart City and Big Data era, the author explore the practice of BIM & GIS in Smart Campus’s Planning Design and Application based on Fujian Normal University. It used Data Augmented Design, GIS spatial analysis, Space Syntax and City Engine 3D modeling to support the location selection of Science and Technology Buildings, build the Building information model and application of BIM tools, design Smart Campus 3D Building Information System. The location based on multi-source GIS data and principle of sustainable development. It has high reliability and offer a case study of building location in campus. The result of Space Syntax showed that the location has the higher choice and integration than others. It’s quite believable on the basis of quantitative analysis. The building information model which based on CGA rules includes internal and external models. The building information models and collision detection tools could help the constructors solve the problem like pipeline collision. The System of Smart Campus Public Participation could provide the functions of public participation based on VR and simulation analysis of sunlight. It aimed better decisionmaking and management.
