SUMMARY:Single vs Twin-Tube Tunnel Configurations in Urban Environments
DESCRIPTION:Overview\nThis instalment of the ITA lecture series will focus on ‘Single vs Twin-Tube Tunnel Configurations in Urban Environments: A Risk-Informed\, Multi-Criteria Decision Framework’. The session is in collaboration with ITA AITES WG20. \nThis episode will feature four parts: \n\nProblem statement – Wout Broere\nGeneral multi criteria method – Giuseppe Gaspari\nCase histories from Asia and Europe – Pedro Ramírez Rodríguez \nCase histories from America – pros/cons – Sotirios Vardakos\n\nFollowing the three presentations there will be time for Q&A with the presenters \nThe ITA lecture series remains free and open to all. For all those that cannot join ‘live’ online\, please register and you will receive a link to stream the episode after the event – this link will be valid for four weeks. After these four weeks\, anyone wanting to watch the episode can do so by registering for the episode on the ITA website\, but there will be a small fee to watch. \nRegister for the event here: https://www.itacet.org/session/lunchtime-lecture-series56/

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.
