NCC offers total consulting services for infrastructure development specializing in shield tunnels, immersed-tube tunnels, and cut-and-cover underground structures in urban areas as well as conventional tunnels through hills and mountains. We also excel at designing shield tunnel segment linings in technically challenging settings that require special tunneling machines such as the Double O Tube or Multi-face types. NCC expertise covers both the hard and soft aspects of project development. We undertake planning, feasibility studies, design, construction supervision, and maintenance of tunnels and other underground infrastructure. We place special emphasis on assisting clients with their public accountability commitments, maximizing project efficiency, and environmental harmony.
