  Safety & Environmental


The most important safety concerns for tunnels are i) safeguarding structures against the seismic forces of large earthquakes and ii) providing measures to cope with any outbreak of fire in confined space.

NCC provides total technological solutions for anti-seismic design:
E determination of the probable characteristics of seismic waves for a given location;
E advanced numerical analysis to create rational earthquake-resistant design of motion-absorbing structures; and
E economical proposals for anti-seismic reinforcement.


Tunnel safety facilities

Minimizing the effects of tunnel fires requires various technical approaches, such as the planning and layout of evacuation facilities and fire-prevention structures that consider human behavior during fire, design of fire-resistant structures for economical post-fire rehabilitation, and ventilation systems for the control of smoke. NCC adopts only the most up-to-date and proven technologies for these purposes.

When it comes to the environment, NCC is committed to ensuring that projects have the least impact possible. We have used our extensive experience and advanced analysis techniques to resolve problems of ground subsidence and lowering of groundwater levels. Moreover, NCC uses computer graphic simulation to design tunnel entrances that are in harmony with the surrounding landscape.
