Airside Road Tunnel

A twin-bore road tunnel link between Heathrow Terminal 5 (T5) to the west of the airport and the existing Central Terminal Area was opened.

Firstco project managed the delivery of the ART’s Communication and Control Systems so that they could be managed from the airport’s ‘Star’ Control Centre.

The following primary services were provided within the main tunnel bores:

  • Tunnel jet fans to provide overall tunnel ventilation in each tunnel bore
  • Fire main running the length of each tunnel bore with trace heating near the portals
  • Steel and tray work supporting LV, data and communication cabling and luminaires
  • CCTV visual coverage and traffic monitoring analysis with smoke detection
  • Combined emergency telephones and fire extinguisher panels
  • Radio re-broadcast leaky feeder cable
  • Variable message signs on the portal ramp roads
  • Fireman’s smoke control panel with inter-linking telephones on both ART portals

There was a requirement for all M&E systems to be controllable automatically. Routine and emergency operational support for the ART and the associated road link is provided from the existing remote ‘Star’ Control Centre and Airport Fire Station. To facilitate this, the following services were provided:

  • Connection to provide external interfaces to the Control and Monitoring System (CMS), CCTV, radio, fire and telecommunication sub-systems
  • Configuration of the existing HEART SCADA system to provide effective representation and operation of the M&E plant and monitoring and operation
  • Expansion of the existing CCTV monitoring system for the provision of an additional CCTV sub-system to provide effective visual coverage of the new road link and tunnel
  • Interfacing of the ART-related emergency and maintenance telephones and radio systems to the external ‘point of presence’ or antenna feeds
