Tunnelling Supplement 2009
Welcome to the inaugural edition of Tunnelling. Brought to you by Great Southern Press, the publishers of Trenchless Australasia, this supplement celebrates Australasia’s dynamic tunnelling industry.David Lees, Editor, AUCT Journal
The industry has experienced a shifting emphasis on certain project types in recent years. Firstly it was road tunnels, then tunnels for desalination plants. Now the emphasis seems to be on underground metros. Whatever the emphasis, the increasing needs of our population – particularly in urban environments – has meant that the Australasian tunnelling industry has kept busy through the recession and is set to surge ahead in the years to come.
John Holland Group’s tunnelling business has achieved numerous milestones in the previous twelve months. In Victoria, Australia’s second longest pipe jack tunnel was completed on the Sugarloaf Pipeline Project and a 3 m diameter tunnel boring machine was launched as part of the Melbourne Main Sewer Replacement Project.
The Bogong Power Development Project has been officially opened by Victorian Premier John Brumby. Earlier in the year Lucy Rochlin visited the site, getting up close with the project’s tunnel boring machine, Aurora Australis.
Tunnelling is an essential component of $A4.8 billion Airport Link, Northern Busway (Windsor to Kedron) and Airport Roundabout Upgrade projects in Brisbane, Queensland – Australia’s largest road infrastructure project.

Precise navigation systems are one of the key elements for successful curved pipe jacking and microtunnelling.
China In a country of 1.6 billion people, The People’s Republic of China is experiencing an unprecedented amount of economic growth, industrialisation and urbanisation. In order to ensure quality of life, it is necessary for infrastructure to continue to develop at the same pace as the population and development of China’s megacities. As such, the extension and modernisation of traffic tunnels and efficient supply and disposal systems are a top priority in the People’s Republic of China.
First soil shifted for Victoria Park Tunnel Project New Zealand Transport Minister Steven Joyce shifted the first soil in November for the Victoria Park Tunnel project, marking the commencement of construction for Auckland’s first urban motorway tunnel.
