Tough Tunnelling
Microtunnelling contractor Edge Underground recently completed a job in difficult terrain in Officer, Victoria The location of Officer, Victoria is renowned as being treacherous for boring contractors, with many complicated ventures undertaken over the past few years.

Microtunnelling overcomes complex conditions
Delegates at No-Dig Down Under 2013 learned about how innovative microtunnelling methods have been utilised as part of the upgrades to Melbourne’s Docklands Precinct through a case study led by Edge Underground Owner Stuart Harrison. The project has involved the installation of 320 m of 400 mm gravity sewer. HOBAS pipe using new microtunnelling technology. The challenges and specifics of this project to be discussed in the presentation include: Complexity Very short timeframes The pipe is 3 m below water table in marine silt (Coode Island silt) The Project is situated 50 m from the shoreline on reclaimed land with many obstructions,...
