Heading into the wet season in northern Queensland, Edge Underground was working against extreme heat and flash flooding on a microtunnelling project to complete three lines – with one under a major state highway. Trenchless Australasia – 15 June 2022
Fighting against the elements and upcoming holidays, planning played a major role in ensuring the success of the project, so that when the worst scenario occurred, Edge Underground could perform its best and get the job done on time.
Edge Underground was subcontracted to complete three microtunnels in Townsville, partnering with Mendi Constructions, a well-known local business. The job required a 450DN, 500DN and 600DN concrete enveloper pipe to be installed – the small two pipes under one road, and the biggest and longest pipe under the Bruce Highway.
