  • 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
