Due to the parametric characteristic of the building information model (BIM), construction data can be added to the component to check whether the design result meets the relevant regulations. When it comes to elevation changes, the 3D model helps the viewer quickly and accurately understand the terrain and mapping data. In other words, BIM is likely to facilitate spatial planning and timely display planning results, and reduce the length of time required to ensure compliance with regulations. To this end, we use BIM to assist the spatial planning of the campus. First, the terrain model is established through Infraworks, and the mass building model is established. By integrating the terrain model and the mass building model, the laws and regulations of the building coverage ratio and sunshine time are checked. After that, a BIM model built through Revit is replacing the mass model in Infraworks. Since the BIM model contains information on the building, the floor area ratio of the building and the legal of designing building components can be checked. We applied the above methods to a University in Taiwan for a case study. The results show that BIM views the overall plan more intuitively and facilitates examing the regulations.
