Abstract
In bedrock construction projects such as dams and tunnels, it is important to have a detailed grasp of the geological structure at the project site and to perform planning and construction appropriate to the situation. To that end, in recent years there have been investigations of various construction information modeling (CIM) management methods that realize 3D modeling of the presumed geological situation and the results of actual geographic observations. This paper describes the creation of a construction site support system for geological risk, in particular issues related to geological information CIM management system development, system content, and application to actual tunnel and dam excavation projects.
