Three-dimensional (3D) building information modeling (BIM) models of alignment-based civil infrastructures such as roads, railways, and tunnels are built as an integrated surface model for each planned linear segment. In the multidimensional (nD) form of BIM, the model can be linked with information such as quantity, schedule, and cost. Furthermore, even if the nD form of BIM is fulfilled, the design and linked information are changed; subsequently, not only must the BIM model be re-created but each link to the information must be updated. In this study, a system was developed to partition the 3D BIM model according to the level required by the user. A partition interval allows the user to input the start and end points or to set a constant interval unit on the basis of the design baseline. In addition, each segment of the partitioned BIM model can be equipped with information such as earthwork volume (cut and fill), cost, and schedule. Finally, a case study was conducted using a road BIM model to verify the developed system.
