Currently, a BIM-based takeoff quantity system is mainly focused on architectural projects. To perform this, diverse takeoff quantity methods such as an object-based automatic takeoff quantity, manual quantity and base functions of calculation have been utilizing. However, since BIM library for road projects include structural elements associated with alignment, it is necessary to establish cost estimation system interlocked with historical cost using 3D library by each length. Accordingly, the aim of this study is to develop cost estimation model with using a historical cost approach so that it can be utilized in construction planning based on the BIM library for road project. For this, based on the BIM library for road, the standardized quantity is estimated, and a process for calculating historical cost and a verification model with a 5D simulation was developed by mapping a WBS code with each BIM library object. This can be applied during the approximate cost estimation process in a project planning and an initial design phase for road projects. Besides, it is expected that these results will be utilized in constructing an optimal historical cost estimation process for project libraries.
