Vertical Tunneling
Large-diameter, deep vertical tunnel
Setting the Standard for Vertical Excavation in Korea
For the past 40 years, we have been leading the construction of large-diameter, deep vertical tunnels, which are key to national security and infrastructure projects such as pumped-storage power plants, radioactive waste disposal facilities, and oil reserve bases.
Railway & Specialized Tunneling
도심지 철도 및 특수터널
We realize perfect underground spaces even in complex urban areas and harsh terrain conditions.
We prevent public complaints and ensure the safety of surrounding structures by introducing low-vibration, low-noise construction methods and smart measurement systems in urban railway and subway sections with a high concentration of underground utilities.
Roads, Bridges & Infrastructure
Roads and large-scale infrastructure
We connect new values of the national territory, transcending geographical limitations.
We precisely construct roads, bridges, and access structures based on large-scale cut, fill, and complex structural construction technologies. We achieve optimal earthwork balance by analyzing site topographical characteristics using data.
Site Development & Utilities
Energy and environmental infrastructure
Laying the foundation for sustainable urban infrastructure
We demonstrate expertise in the foundational processes that complete the functions of energy infrastructure essential for economic and industrial growth in the AI and digital era, ranging from pumped-storage power plants to radioactive waste disposal facilities.
