Construction project pre-design phase is highly influential in setting the directions for the whole business and project to proceed. Thus, it is essential to collect and analyze enormous amount of data related to construction project. So far, the pre-design phase in a project was depending on experts' experience and intuition. However, as construction projects become larger and more complex, the amount of related information and analyzed data increases. Therefore, the necessity arises for a plan that could directly support the pre-design phase. In this paper, BIM was suggested as a tool that will support the pre-design phase, and so the concept and role of pre-design BIM is defined. The framework of pre-design BIM simulation is composed using the international standard model IFC and how the pre-design BIM simulation system can support the process is illustrated.
