| Research Abstract |
Recently, 3D product models are used for design and construction of bridges. However, development of detailed 3D product models for a large number of existing bridges for the purpose of maintenance is economically unrealistic. Thus, in this research, we devised a plan of levels of development (LOD) for bridges, and we measured time for making a 3D product model for each LOD and obtained a cost curve. As per the benefit, we decided to use questionnaires by asking professionals. In addition, we linked the evaluation of each member of a bridge with the 3D product model and modified the 3D model as a 4D model by linking repair works to the 3D model in a time axis.
