SUMMARY:ATS QLD - Project Delivery of Bulimba Creek and Fotrose Rising Main Projects
DESCRIPTION:Joint the ATS and ASTT in a joint technical presentation on real-world lessons learned on Australian micro-tunnelling projects. \nDelivered by Abergeldie’s Technical Director for Tunnelling\, Grant Schultz\, attendees will learn of the key takeaways from two local projects from end-to-end. \nIn his current role\, Grant oversees all underground projects across Australia and New Zealand. \nThroughout his presentation\, Grant will share with you the works completed by Abergeldie in relation to the Bulimba Creek and Fortrose Rising Main Projects for QUU from time of tender\, right though to design to project delivery. \nBulimba Trunk Sewer is a tunnel project involving a total of 3600m of 1800mm OD Tunnel which is installed using the Pipe Jacking Method. Within\, the project had shafts up to 65m deep\nand Single Drive lengths up to 853m long. \nFortrose Rising Main was a tunnel 46m under the Brisbane River. This tunnel is 560m long and was constructed using the Pipe Jacking method\, also involving a compound curve alignment. \n\n\n\nDate: Thursday 8 August 2019 \nTime: 5.30pm to 7.00pm \nVenue: Hawken Auditorium\, Engineering House\, 447 Upper Edward St\, Spring Hill QLD 4000 \nCost:Free for Members & Students/$30 for Non-Members \nSpeakers: Grant Schultz \nSession Contact: memberservices@engineersaustralia.org.au \nClick here to see flyer \nClick here to register

SUMMARY:ATS QLD - Oberau Bypass Tunnel
DESCRIPTION:Delivered by experienced international Civil Engineer Erik Neun\, you will partake in an evening of discussion on the learnings from the Oberau Bypass Tunnel: A 3km-long project that underpasses various buildings\, and traverses alpine rock formations and grainy soil in Gießenbach Valley. \nDue to the possibility of a sudden rise of groundwater levels above the tunnel alignment in cases of heavy rainfall during tunnel excavation\, the installation of a groundwater lowering well gallery has been called for. \nConsideration has also been given to the impact of surface settlements caused by the tunnelling in the builtup area of Oberau. Based on an initial assessment of expected settlements\, compensation grouting has been foreseen for three buildings (two workshops with individual foundations and a residential building with a raft foundation). \nThe paper being discussed focuses on various aspects of the design and construction of the tunnel\, and the experience with and lessons learned from the project\, including limitations of FE modelling concerning the influence of specific tunnelling technics\, the compensation grouting\, and the optimisation of forward spiling. \n\n\n\n\nDate: Wednesday 21 August 2019 \nTime: 5.30pm to 7.00pm \nVenue: Hawken Auditorium\, Engineering House\, 447 Upper Edward St\, Spring Hill QLD 4000 \nCost:Free for Members & Students/$30 for Non-Members \nSpeakers: Erik Neun \nSession Contact: memberservices@engineersaustralia.org.au \nClick here to see flyer \nClick here to register

SUMMARY:ATS VIC - Water Ingress in Long TBM Tunnels: Its Mitigation and Control
DESCRIPTION:Overview\nThe 15km headrace tunnel for the Uma Oya Multipurpose Development project in Sri Lanka was excavated by double shield TBM and intersected large quantities of water. The study of this project with regards to better understanding the effects of the tunnel on the hydro-geology of the area\, identifying relevant in-tunnel investigation techniques\, and developing better pre-excavation and post excavation grouting systems is relevant to other long hard rock TBM projects. \nThe presentation will address why we need to limit the water ingress into tunnels under construction with regards to the potential effect on the environment with dewatering of surface and near surface aquifers\, the effect on the construction and its schedule\, and the methods available for prediction and control of ground water during tunnel excavation. The paper will also present examples from other projects around the world\, including past completed projects\, projects under construction and future planned projects\, detailing how such hazards have been or will be treated. \nSpeaker\nDavid Lees \nDavid Lees has over 35 years’ experience in the design and construction of underground works\, both in mining and civil tunnelling\, with particular expertise in grouting and ground treatment. He has worked in over 14 countries around the world as both consultant and contractor. From August 2015 to August 2018 David was Chief Site Supervisor on a 15km TBM tunnel in Sri Lanka. The project had enormous problems with water ingress – up to 1000l/s from the face – causing heavy delays to the project and widespread social and environmental problems. David joined the project halfway through and took the opportunity whilst on the project to prepare a thesis for a PhD through the local university of Peradeniya. The presentation is based on his PhD thesis. \nNOTE: This event starts with networking at 5:30PM followed by the presentation at 6:00PM-7:30PM.
