SUMMARY:Testing of Sprayed Fibre Reinforced Concrete for the Design of Tunnel Linings
DESCRIPTION:REGISTER NOW!\nAssessing toughness characterization of sprayed FRC by adopting EN14488-3 2022 Method B\nEvent overview \nFibre reinforced concrete (FRC) design has been widely used for sprayed permanent linings in tunnels with substantial recent developments in design methods and mix design. One such development has been reliance on the toughness characteristics to inform the design versus the different methods of panel testing. This presentation discusses the 2025 fib bulletin 116 recommendations with a focus on testing and performance criteria. By adopting EN 14488-3 procedure for the toughness characterisation of the sprayed FRC\, it is possible to derive the key parameters that are necessary for the design according to fib Model Code 2010 in an easy quantifiable manner. \nThe presentation will also highlight the advantages and drawbacks of various shotcrete testing methods\, the importance for shotcrete testing to directly relate to design methods\, and an insight into the latest shotcrete testing methods. \nTimings \n\n5:30pm: Welcome and networking\n6:00pm: Presentation\n6:45pm: Q&As\n\nSpeaker\n\nGAN Cheng Chian\nB.

SUMMARY:David Sugden Roadshow - Melbourne - Uncovering veins: impacts on deep tunnel engineering
DESCRIPTION:Overview\nHydrothermal veins are often overlooked or misinterpreted within deep\, heterogeneous rock masses\, yet their behaviour can dramatically influence tunnelling outcomes. In his award winning 2025 David Sugden Award paper\, Yosafat Sinaga reveals how these vein systems are frequently mistaken for open joints\, leading to inaccurate geological models and flawed design assumptions. This session will explore why correct vein characterisation is essential for both safety and project efficiency. Misjudging these features can result in two costly extremes: overly conservative support designs that inflate construction budgets\, or unexpected\, hazardous rockbursts triggered by misunderstood ground conditions. By examining real case insights and engineering implications\, this event will provide tunnelling and geotechnical professionals with a deeper understanding of the subsurface complexities that lie beneath\, and how better interpretation can reduce risk and improve decision making. \nLearning outcomes\n\nWalk away with practical steps to avoid design errors caused by misinterpreting veins in deep tunnel projects.\nCorrectly interpret veined rock masses in core logging and face mapping and recognise when “broken-looking” core does not mean a poor-quality\, jointed rock mass.\nHow vein intensity and in situ stress interact to drive overbreak\, damage propagation\, and reinforcement demand in high-stress excavations\n\nAbout the speaker\n\n\n\nYosafat Sinaga\nGeotechnical Engineer\, NOMA Consulting\nYosafat Sinaga is a Geotechnical Engineer at NOMA Consulting with over five years of experience delivering geotechnical design and construction support for mining and tunnelling projects in Australia\, Singapore\, Papua New Guinea\, and Indonesia. He has contributed to major infrastructure and underground mining developments\, specialising in rock mass and structural geological characterisation\, advanced 2D and 3D numerical modelling\, and primary tunnel support design optimisation. His recent project work includes optimising primary support design for road tunnels excavated using the Drill & Blast method\, developing detailed designs for temporary Earth Retaining and Stabilising Structures (ERSS) for rail and service tunnels\, and providing geotechnical input for underground copper mining projects employing sub-level and block caving methods.

SUMMARY:Smarter stress estimation for Australia's expanding underground infrastructure
DESCRIPTION:Overview\nAustralia’s underground infrastructure pipeline is expanding rapidly\, from metro and road tunnels to caverns for pumped hydro energy storage and subsurface storage facilities. As we push deeper and into more complex ground\, reliable estimation of in-situ stress becomes increasingly important for safe\, economical excavation design. Yet the conventional ways of measuring stress – overcoring and hydraulic fracturing – are expensive\, slow\, and often difficult to carry out reliably\, especially in weak or complex ground. Meanwhile\, the drilling and geophysical logging programs we already run on most projects generate large volumes of borehole data. Much of this data goes underused. \nThis presentation shows how borehole breakout data\, the localised failures that form on a borehole wall when stress concentrations exceed the rock’s strength\, can tell us more than just the direction of stress. By analysing breakout geometry\, we can also estimate the magnitude of horizontal stresses. The method draws on laboratory testing\, 3D breakout geometry extraction\, numerical modelling\, and machine-learning techniques that estimate rock strength from geophysical logs. This research has been incorporated into BBSET.NET\, a free web-based tool that enables practitioners to estimate stress from routine borehole observations. \nKey takeaways include: Breakout geometry indicating stress magnitudes\, not just orientation. Routine borehole logging data holds untapped value for stress estimation. BBSET.NET utilisation as a practical\, accessible tool for project teams. \nThis event is free for all ATS Members \nLearning outcomes\nIn this event\, you will understand: \n\nusing borehole breakouts to estimate underground stress direction and magnitude\, getting more value from routine borehole and geophysical logging data\ndigital tools and BBSET.NET for practical stress estimation.\n\nProgram\n\n5.30 pm AEST: Guest arrivals and registrations\n6.00 pm AEST: Presentation begins\n6.45 pm AEST: Q/A begins\n7.00 pm AEST: Event concludes\n\nAbout the speaker\n\n\n\nJoung Oh\nAssociate Professor – UNSW School of Minerals and Energy Resources Engineering\n\nDr Joung Oh is an Associate Professor in the School of Minerals and Energy Resources Engineering at UNSW Sydney. He has over 20 years of experience in geotechnical and mining engineering\, spanning both industry and academia in the US and Australia.  After completing his PhD\, Joung worked as a research associate and licensed Professional Engineer (PE) on projects including rock slope failure analysis\, ground movement assessment in urban areas\, and underground cavern stability evaluation. From 2009\, he served as a senior geotechnical and tunnel engineer at Parsons Brinckerhoff (now WSP)\, contributing to major tunnel and infrastructure projects in Manhattan and internationally. Since joining UNSW in 2013\, Joung has led numerous industry- and government-funded research projects and provided consultancy to mining companies. He currently supervises 11 PhD candidates and has guided 19 postgraduate students to completion. He has authored over 100 journal articles and conference papers and chairs the School’s Teaching and Learning Committee.
