Tunnels and Bridges are more than stone, brick and metal
Tunnels and bridges are today foreseen with sometimes up to 50 technical installation components. From emergency systems, surveillance, ventilation up to (ground)water management systems, a tunnel or bridge are fully equipped with technology.
Local installations standards for tunnels and bridges determine:
- Minimum level of light required
- Mechanical ventilation capacity (tunnels)
- Emergency exit signing
- Emergency phone network
- Sound installation ( if applicable )
- Surveillance software performance
- System required to close the tunnel
- And many more
The required level of power distribution and network structure is therefore quite significant with high standards when it comes to operability.
