UGL was the principal mechanical and electrical engineering contractor for the Clem 7 tunnel, delivering one of the largest and most complex control and communications systems in Australia. Despite its size and complexity, the system provides a one second response time for each of its 170,000 supervisory control and data acquisition (SCADA) tags, and operates with an availability exceeding 99.995%.
UGL’s scope of work for the Clem 7 project included:
- project management
- engineering
- procurement/ fabrication
- construction and
- commissioning
The tunnel was built by a joint venture, consisting of Leighton Contractors, Baulderstone, and Bilfinger-Berger. The joint venture engaged UGL to design and construct the tunnel’s mechanical and electrical services, including the control and communications system.
The M7 Clem Jones Tunnel – also known as the Clem 7 - is the central part of a 6.8km-long tollway system built for $3 billion. This system links five major Brisbane roads, including the Pacific Motorway, Ipswich Road, Lutwyche Road, the Inner-City Bypass and Shafston Avenue at Kangaroo Point. The M7 Motorway system’s Clem 7 tollway joins Brisbane’s southern suburbs to the north, enabling alternate connectivity to the airport.
