Company information
Many of the social infrastructures such as roads, tunnels, bridge piers, railways, water supply and sewage systems, and ports, which were intensively developed after the period of rapid economic growth, will reach over 50 years since their construction around 2030. There are concerns about the aging of social infrastructure. Additionally, due to the declining birthrate and aging population, Japan is facing a decrease in its population, leading to challenges such as labor shortages and worsening fiscal conditions. As a result, there is a growing demand for establishing a maintenance cycle for future social infrastructure, with increasing needs for "inspection," "diagnosis," "repair," and "renewal." Measurement technology services aim to contribute to the development of social infrastructure and a society where people can live with peace of mind by providing services based on the "knowledge," "experience," and "technology" cultivated since its founding in 1995. These services include the sale, repair, and calibration of non-destructive testing equipment and buried object detection devices, as well as customization and development of equipment and software, rental services, consultation for surveys, dispatching instructors, and holding seminars.
