During the 1990s, CAD/CAE/CAM-related technologies and digitization of design and engineering processes had advanced rapidly in the machine manufacturing industry. Through the appearance of 3D CAD and its evolution, tasks including simulation have become easier and the period of development has been reduced. Through the rapid growth  of  BIM  in  the  construction  engineering  industry,  mandatory  use  in  government  procurements  and utilization for improving productivity, the importance of 3D product modeling in the civil engineering field is becoming  increasingly prominent.  In  an  attempt  for  government  organizations  to  implement  Earned  Value Management (EVM) using 3D modeling, this study evaluates the 3D product model of a bridge in order to establish quantity  survey  contract  units  of  government  organizations.  Firstly,  the relationship  of  the  work  breakdown structure in EVM and the government contract units are organized. Next, the relationship of WBS furnished with the government contract units and the 3D modeling of the bridge structure is defined. Finally, by using the 3D product model of the bridge structure, generated in accordance with the ER diagram and quantity surveying of work items required by government organizations, usability of EVM is evaluated.
