Tunnel & Bridge Systems

We have been involved with bridges and tunnels since the QE2 Bridge at Dartford was being built in the 1990s. What started as a bridge lighting control system expanded until it became a web based supervisory system for:

  • Electrical Distribution for both the bridge and the tunnels
  • Emergency generators and load bank
  • Pumping for the Dartford site and other locations around the M25
  • Tunnel fire detection, pollution detection and ventilation
  • Tunnel emergency evacuation lighting
  • Water mist Fixed Fire Fighting System
  • Weather monitoring
  • Fault management
