For more than a century since its founding, We have contributed to the development of society through the construction business. We leverage our world-class technical strengths in our many construction projects, wining trust internationally.

Over time, We have continued to develop innovative technologies in order to meet society's needs. As an earthquake-prone country, particular attention is given to earthquake-proofing technologies, and we have innovated in this field, as well as all technologies connected with construction, including technologies for energy-efficient buildings and streamlining tunnel construction.

We harness our advanced technical capabilities and global network to form project teams that are always ideally suited to the project at hand. Around the world, our highly expert engineers and experienced project managers collaborate to execute projects that ensure our clients' satisfaction.
