Eight years have already passed since the MLIT announced the concept of CIM (called BIM / CIM from 2018). The port construction started as a trial construction in 2017, and in 2023, all construction projects are subjected to CIM except for some exceptions. CIM aims to accumulate and utilize information centered on 3D information in all phases of survey, design, construction, and maintenance. In construction, we make a three-dimensional construction plan, discover problems such as interference prior to construction, a safer and more efficient construction methodology, and use it to manage how accurately the results can be implemented on-site. The guidelines of utilizing these data in the future were studied based on the conventional construction method, the current utilization method, and the future.
