PDS have been successfully implementing Tunnel Control System projects for over 18 years and have earned a reputation of being the leader in this field within the UK, whilst also providing projects worldwide. Our MATRICS Tunnel Control System solution has evolved to encapsulate this experience by combining modern control system hardware with a semi-configured SCADA solution in which we have embedded numerous operator facilities, many based on direct client feedback.

Our tunnel clients include the Tyne Tunnel in Newcastle, the Mersey Tunnels in Liverpool, the Butetown Link tunnel in Cardiff, the Clyde tunnel in Glasgow, the Jack Lynch Tunnel in Ireland, and at Heathrow Terminal 5 for BAA. Most of these projects include the control and monitoring of all plant, including traffic signage, tunnel lighting and ventilation, sumps and pumps, electrical distribution and standby supplies, communication systems and fire and security systems.
