Installing a sewer line under a railway is no simple task at the best of times. What if you had just two days to complete it? Edge Underground found itself in such a position when the Gold Coast City Council asked for a gravity sewer line to be installed via trenchless technology along the Old Pacific Highway in Pimpama, with a section of the sewer line needing to be installed beneath a section of the Queensland Railway. There was one major condition with the project: the railway had to be reopened within 48 hours, ‘no ifs, no buts’.

Stuart Harrison caused a stir in the microtunnelling industry when the Vermeer AXIS laser guided boring system was officially launched in 2009. Since then, laser-guided machinery has been used to install hundreds of thousands of metres of sewer and water pipelines around the world, and has changed the game for pipeline projects in Australia. So what makes laser guided microtunnelling a standout in the crowded field of trenchless pipeline installation methods? Apart from the science fiction appeal, laser guided systems offer a number of real advantages that all serious pipeline project managers should be aware of.
