SABO facilities require daily maintenance, and maintenance plans are necessary considering life cycle costs. Changes in socio economic conditions have necessitated improvements in social and public services and the advancement of businesses, organizations, processes, and working styles within the construction industry. Digital transformation (DX) can help to improve safety, security, and prosperity within the construction industry. When maintaining SABO facilities, it is important to clarify specific policies for life cycle cost reductions in the form of short term numerical targets, using new technologies related to inspections, repairs, and cost reduction effects. To facilitate DX in the infrastructure field, the introduction of BIM/CIM (Building/Construction Information Modeling) promotes design verification, visualization of construction plans, and efficiency improvement. Furthermore, safety and labor savings are supported in terms of construction and maintenance performed using unmanned construction and aerial vehicles. In particular, in the field of SABO, the development of new technologies related to topographical analysis, performance verification of structures, monitoring, data collection/analysis/transfer, etc. is expected. Here, we present an overview of an our SABO maintenance system and propose the development of a new system through DX. By introducing the basics of the maintenance system that has been built to date, we expect that the maintenance of SABO facilities that utilize DX will be further enhanced using the findings of this study.
