Domestic Construction Business (Civil Engineering)

We contribute to a safer, more secure, and richer society by constructing the infrastructure which our lives depend on: tunnels, bridges, dams, river works, urban civil engineering structures, railroads, expressways, and more. In recent years, we are expanding our business domain to maintenance, including upgrades, and repairs as we actively endeavor to extend the lives and functionality of existing infrastructure.
Additionally, we will increase productivity as well as safety and achieve work style reform through the promotion of construction DX such as with development and application of automation and autonomizing technologies for construction.
