SUMMARY:Testing of sprayed fibre reinforced concrete for the design of tunnel linings
DESCRIPTION: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 characterization 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. \nLearning outcomes\nIn this presentation\, you will: \n\nunderstand the advantages and drawbacks of various shotcrete testing methods\nunderstand the importance for shotcrete testing to directly relate to design methods\ngain an insight into the latest shotcrete testing methods.\n\nProgram\nIn-person: \n\n5.30 pm AEST: Registrations open\n6.00 pm AEST: Presentation begins\n6.45 pm AEST: Q&A session\n7.00 pm AEST: Networking\n8.00 pm AEST: Event ends\n\nAbout the speaker\n\n\n\nCheng Chian Gan\nTechnical Manager\, Underground Solutions – Bekaert Singapore\n\nGan is an expert in sprayed fibre reinforced concrete with over 35 years of civil engineering experience. He is a member of the Working Group on SS674-2021 since Jan 2019. Gan is a domain Expert for Sprayed Concrete and Fibre Reinforced Concrete under Intelligent National Productivity and Quality Specification Singapore since Mar 2019. From 1998 to present\, Gan has been involved in over 22 sprayed fibre concrete tunnel linings and over 20 fibre concrete precast segmental and cast concrete tunnel lining projects.

SUMMARY:Conversations that connect: mentors & mentees
DESCRIPTION:Overview\nTransform the way you connect with your mentor or mentee. This interactive hybrid workshop (featuring innovative ‘watch parties’ in Sydney\, Melbourne and Brisbane) focuses on moving beyond surface-level networking to purposeful\, engaging conversations that build lasting value. It is being delivered by the ATS Diversity Group’s cutting edge Mentor Alliance Program. \nParticipants will learn how to design effective discussion frameworks\, apply practical networking strategies\, and co-create ideas for future mentor–mentee catch-ups. Led by an online expert and supported by local facilitators in Melbourne\, Sydney\, and Brisbane\, the session features hands-on activities that spark meaningful\, structured dialogue. \nJoin fellow mentors and mentees in your local hub to deepen connections\, strengthen your mentoring relationships\, and help shape how the Mentor Alliance connects in the future. \nWhile it is a Mentor Alliance event\, it is open to everyone within ATS. \nNOTE – This exciting event is intended to be delivered by Patricia online to ‘watch parties’ in Melbourne\, Sydney and Brisbane’s EA offices\, so people can connect and use these as “breakout rooms.” We urge you to attend one of these watch parties in person as you’ll get more out of the experience that way.  \nLearning outcomes\nIn this presentation\, you will learn: \n\nFramework Design: Learn how to select and structure discussion starters that move beyond small talk to deep engagement\nApply Networking Strategies: Practice hands-on techniques for sparking meaningful\, structured dialogue within the Mentor Alliance community\nFuture Collaboration: Be part of creating ideas for future catch ups between you and your mentor/mentee.\n\nProgram\nIn-person: \n\n5.30 pm AEST: Registrations open\n6.00 pm AEST: Presentation begins\n6.45 pm AEST: Q&A session\n7.00 pm AEST: Presentation ends\n7.30 pm AEST: Event ends\n\nOnline: \n\n6.00 pm AEST: Webinar begins\n6.45 pm AEST: Q&A session\n7.00 pm AEST: Webinar ends\n\n\n\n\n\n\n\n\n\n\n\nSpeaker\n\n\nUnfortunately\, Patricia Kaziro (who was originally scheduled to lead the session) is unwell\, but we’re pleased to share that our ATS QLD Chair\, Annalena Chapman\, will now be stepping in to lead both the presentation and the event. This will be a valuable and insightful discussion under Annalena’s guidance\, and we strongly encourage attending in person with us.

SUMMARY:David Sugden Roadshow – Sydney – Uncovering veins: impacts on deep tunnel engineering
DESCRIPTION:Save the date – Registration details to come\nOverview\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.
