Overview

Join the Australian Tunnelling Society for a presentation on microtunnelling, featuring some challenging trenchless projects across Australia such as Gold Coast Seaway project with a 1400m pipe jack bore in difficult ground conditions under the Broadwater and an 878m long HDD under the Nerang River.

David Medcalf, Trenchless Construction Manager for John Holland, will be presenting about the projects, as well as Victorian projects such as construction of the Epping Main Sewer and the Kalkallo Creek Main sewer, including the challenging ground conditions that were overcome on these projects. O’Shannassy’s Reservoir Outlet Renewal project, to be constructed as part of the Melbourne Water Capital Works Programme, is another project in challenging ground conditions with igneous rock up to 260MPa combined with highly weathered material in a 450m bore through the mountainside.
