SUMMARY:David Sugden Roadshow - Brisbane - 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. \nProgram timeline\n5:30pm AEST – Registration and networking \n6:00pm AEST – Presentation commences \n6:50pm AEST – Q&A \n7:00pm AEST – Presentation concludes\, networking \n7:30pm AEST – Event concludes \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:SLAM LiDAR for transport tunnel surveying
DESCRIPTION:Overview\nThe term “mobile mapping” is well established in the survey industry — typically referring to large vehicle-mounted systems that combine high-end LiDAR with precision GNSS and IMU hardware. These systems are powerful\, but they are expensive\, require GPS to function reliably\, and are fundamentally limited by what a vehicle can reach. This presentation introduces a different class of technology: SLAM-based mobile LiDAR scanning. Rather than relying on GPS and inertial positioning\, SLAM (Simultaneous Localisation and Mapping) builds a map of the environment in real time and uses that map to track its own position — making it inherently suited to GPS-denied environments such as tunnels\, underpasses\, and confined underground spaces. We’ll explain how SLAM works from first principles\, how it compares to traditional survey methods (total stations\, static TLS) and conventional mobile mapping systems\, and where each approach has genuine advantages. We’ll also discuss SLAM’s limitations: where it struggles\, what affects accuracy\, and the scenarios where traditional methods remain the better choice. Attendees will leave with a grounded\, practical understanding of how SLAM-based mobile LiDAR works\, how it fits alongside conventional survey techniques\, and when it is — and isn’t — the right tool for a tunnel project. \nProgram timeline\nOnline \n5.30pm – Presentation commences \n6.15pm – Q&A \n6.30pm – Presentation concludes \nIn-person \n5.00pm – Registration opens \n5.30pm – Event commences \n6.15pm – Q&A \n6.30pm – Event concludes \nLearning outcomes\n\nWhat SLAM is and how it differs fundamentally from GPS/IMU-based mobile mapping systems\nThe trade-offs between SLAM-based scanning\, conventional MMS\, static TLS\, and total station survey — and how to choose the right approach\nAn overview of Emesent’s Hovermap ST-X and GX1 platforms and how they are deployed in tunnel environments (drone\, vehicle\, backpack)\nWhat real transport tunnel scanning data looks like\, and how it flows from capture through Aura to engineering deliverables\nHonest limitations of SLAM-based scanning and the scenarios where it is not the best fit\n\nAbout the speaker\n\n\n\nStefan Hrabar\nChief Strategy Officer & Co-Founder\, Emesent\n\nDr Stefan Hrabar is Chief Strategy Officer and Co-Founder of Emesent\, a global leader in autonomous mapping technology. With a background in robotics and autonomous systems research at CSIRO\, Stefan co-founded Emesent in 2018 to bring advanced SLAM-based mapping technology to real-world infrastructure and industrial environments. He has worked extensively on the application of mobile LiDAR and autonomous systems in GPS-denied and access-restricted environments\, including tunnels\, mines\, and complex built infrastructure.

SUMMARY:Modernising Tasmania's hydropower legacy
DESCRIPTION:Note this event is online and in person in Brisbane \nOverview\nTasmania’s hydropower network has played a critical role in Australia’s renewable energy landscape for more than a century. As ageing infrastructure is upgraded to meet future energy demands\, engineers are increasingly required to balance operational continuity\, complex geology\, environmental considerations\, and modern construction approaches. \nThis presentation will provide an overview of the Lake King William upgrade works delivered by Hydro Tasmania and Entura\, with support from PSM as part of the Integrated Owner’s Engineering Team. Located in Tasmania’s Central Highlands\, the project involved excavation through challenging Jurassic dolerite and required innovative engineering and construction solutions to manage geotechnical risk\, site constraints\, and long term asset performance.  Attendees will gain practical insights into the delivery of large scale hydropower infrastructure projects\, including stakeholder collaboration\, engineering decision making\, and lessons learned from working in complex geological conditions. The session will also explore the broader importance of hydropower modernisation in supporting Tasmania’s renewable energy future and maintaining resilient energy infrastructure. \nProgram timeline\nOnline \n6.00pm – Presentation commences \n7.00pm – Presentation concludes \nIn-Person \n5.30pm – Registration opens\, catering & refreshments \n6.00pm – Presentation commences \n7.00pm – Presentation concludes \n7.30pm – Event concludes \nLearning outcomes\nIn this presentation\, you will learn : \n\nHow hydropower infrastructure upgrades support Tasmania’s future energy system\nKey engineering and geotechnical challenges encountered on the Lake King William upgrade\nPractical approaches to managing excavation and construction risks in complex geological environments\nLessons learned from collaboration across integrated engineering and project delivery teams\n\nAbout the speaker\n\n\n\nHarry Buchanan\nSenior Geotechnical Engineer\, PSM\n\nHarry is a senior geotechnical engineer with a keen interest in underground structures and mining.
