NEXCO EAST Group has actively introduced ICT and mechanization based on the promotion of examinations based on solving various issues at the site in order to secure long-term "safety and security" of road infrastructure. In order to build a comprehensive maintenance system that integrates with engineers, we announced the “SMH Concept” in July 2013 and established the SMH Promotion Team in the Headquarters Management Business Headquarters in September.
After that, as a result of proceeding with a study to make it more concrete, in May 2014 we upgraded it from “concept” to “basic plan” and are working on full-scale efforts toward the realization by 2020. .
