SUMMARY:Rozelle Interchange Project - Presentation and Q&A
DESCRIPTION:Overcoming the complex geometry and geology during design and construction of the Rozelle Interchange tunnel network\nTHURSDAY 1 AUGUST – REGISTRATION LINK NOW AVAILABLE!\nRozelle Interchange was the final stage (Stage 3b) of the WestConnex project. As stated in the project title\, ‘Interchange’\, this project linked the M4 East and M4-M8 Link projects with the future Western Harbour Tunnel project. To achieve these connections and minimise surface impacts\, complex road and underground ventilation alignments were needed. This presentation covers design and construction challenges to overcome the complex road alignment (including 50 tunnel over tunnel crossovers) and equally complex geology. \nTimings\n5:30 – 6:00 – Networking and snacks \n6:00 – 7:00 – Presentation and Q&A \n7:00 – 8:00 – Networking \nLearning outcomes\n\nUnderstand the Rozelle Interchange Tunnel.\nLearn how complex geology coupled with complex road geometry\, including 4 levels of tunnels was safely constructed.\n\nSpeakers\n \nBeatriz Estrada\nPrincipal\, PSM \nBeatriz is a Principal Engineering Geologist at PSM. She has worked as part of the design and construction teams of numerous tunnel projects. She has been the technical lead for the development of the geotechnical models for multiple tunnel projects in Sydney including Rozelle Interchange\, Sydney Metro City and Southwest and Western Harbour Tunnel\, Southern Tunnel Works. \n  \n \nMark Trim\nPrincipal Tunnel Engineer\, Delve Underground \nMark is the Underground and Tunnels Practice Lead for Delve Underground’s Australian and New Zealand Region. He has 26 years of experience working as a design engineer and design manager specializing in permanent and temporary underground structures.

SUMMARY:Road tunnel ventilation optimisation using 1D modelling
DESCRIPTION:Overview \nThis event offers invaluable insights into improving road tunnel ventilation systems. \nHear first-hand from experts who collaborated with Australian road tunnel operators to enhance their ventilation using advanced simulation tools. Learn how Ventsim DESIGN\, a 1D network flow simulation tool with a 3D graphical user interface\, was adapted for tunnel-specific challenges like jet fan pressure and vehicle piston effects. \nDiscover the detailed process of building validated models\, calibrated with real-time sensor data\, and how these models were used to trial and implement successful changes. Key topics include reducing power consumption\, optimising fan use and modifying emission requirements. \nBy attending\, you’ll gain practical knowledge applicable to tunnel ventilation and other engineering challenges\, witnessing the real-world impact of these innovations. Don’t miss this opportunity to network with industry professionals and stay ahead with cutting-edge ventilation solutions. \nLearning outcomes \nIn this presentation\, you will learn about: \n\nThe approach taken in modelling ventilation in operational road tunnels\, informed by experience in underground mine ventilation and model calibration.\nVarious approaches taken in mining and how they may or may not be applicable to tunnel ventilation.\n\nAbout the speakers \n\nFlorian Michelin\nBrisbane Manager\, Howden Ventsim\n\nFlorian Michelin is the Howden Ventsim Brisbane Manager. Florian Michelin is a mechanical engineer\, specialising in computational fluid dynamics. They started as a software developer at Chasm Consulting (now owned by Howden)\, developing new features and improving simulation algorithms in Ventsim™. This led to the development of Pumpsim\, a software for liquid pipe flow simulation\, and Florian became the product manager for Pumpsim\, as well as trainer and consultant using Ventsim and Pumpsim. Now\, they are the manager for Howden Ventsim Australia\, responsible for development\, sales\, training\, and consulting activities for Ventsim and Pumpsim products.\n\n\n\nDr Martin Griffith\nSoftware Team Leader\, Howden Ventsim\n\nDr Martin Griffith is the Howden Ventsim Software Team Leader. He has worked in ventilation network modelling software development and consulting projects at Howden Ventsim for seven years. Prior to this\, he worked for a decade in fluid dynamics research at Monash and Swinburne Universities. He has a PhD in Mechanical Engineering.

SUMMARY:DAARWIN-GEMINI A novel tool to predict advance rate of a TBM in real-time
DESCRIPTION:Overview\nSAALG Geomechanics\, in collaboration with ACCIONA\, has developed DAARWIN-GEMINI\, a software system designed to optimize the performance of tunnel boring machines (TBMs) using machine learning-based techniques. The system key features include an advanced architecture for querying and processing data from the TBM database\, big data analysis and visualization in a web browser\, a ground-machine interaction model to predict the TBM advance rate and operation anomalies detection via machine learning algorithms to enhance the efficiency and reliability of tunnel excavation operations. The system has been validated in the Mularroya (Spain) hydraulic tunnel (small diameter shield TBM) in fractured rock mass with faulted and sheared zones\, and implemented in a larger diameter tunnel with EPB in Sao Paulo (Brazil) in weathered granite materials. In both cases\, the ground-machine excavation model was trained with excavation data from each tunnel and the model was deployed to provide real-time predictions of the penetration rate during the TBM operation. \nThis is an in-person and online event. \nLearning outcomes\nIn this presentation you will learn: \n\nHow machine learning is being applied within the tunnelling industry to improve productivity and reduce risk.\nA statistical approach to a ground-machine interaction model to predict the penetration rate of a TBM from performance parameters and geotechnical parameters.\nArchitecture and workflow of a system capable of providing predictions of the penetration rate at ring level and perform geotechnical back-analysis to assess spatial variability of ground parameters.\nLessons learned from the implementation of the system in two case studies\, a small diameter hydraulic tunnel in Spain and a metro tunnel in Brazil.\n\nEvent program\n\n5:30 pm AEST:  In-Person event registration opens\n6:00 pm AEST:  Event commences (online event starts here)\n7:00 pm AEST:  Event concludes\n\nAbout the speaker\n \nIgnasi Aliguer \nCTO and Co-Founder\, SAALG Geomechanics \nIgnasi Aliguer is Chief Technology Officer and Co-Founder at SAALG Geomechanics\, a software company and engineering firm focused on advanced digital tools for geotechnical engineering problems. Ignasi worked as a Research Engineer at Tech. University of Catalonia\, focusing on hydraulic fracture numerical simulations working with a major oil company.

SUMMARY:Geocomposite Tunnel Invert Drainage - Online technical presentation
DESCRIPTION:Presentation abstract:  \nCavidrain Invert geocomposite systems are used to form a drainage layer beneath the road pavement of tunnel floors. The use of Cavidrain Invert offers a number of advantages over more traditional methods (which use crushed stone and pipes) such as: (i) reduced excavation (as they form a much thinner layer compared to crushed stone layers\, requiring less excavation thus accelerating the construction process); (ii) faster installation (they can be quickly laid down\, reducing installation time compared to traditional methods); (iii) lower costs (achieved through the reduction of excavation and the acceleration of the construction process); (iv) improved drainage (as they provide larger void to facilitate a better water flow compared to crushed stone and thus ensuring effective drainage); (v) reduced mineral scale buildup (by mitigating problems caused by mineral deposits that can clog traditional drainage systems). This presentation demonstrates the use of Cavidrain Invert in projects such as the Cross River Rail and how these projects integrated this system into the design and construction. \nSpeak Bios: \n \nGoran Erak \nCivil engineer with 33 years of experience in the UK\, Europe\, Africa and Middle East\, working on a number of challenging projects within a variety of sectors\, including environmental\, tunnels\, highways\, rail\, water\, mining\, structural and residential. \nResponsible for the ABG Geosynthetics Civils division globally\, including monitoring design output for specific projects in this sector and dealing with civil engineering consultancies\, contractors\, government organisations and coordinating research projects with universities.
