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:The ground investigation for a storage cavern in metamorphic rock at 600 m depth
DESCRIPTION:Overview\nThis presentation describes the processes used in the investigations for a deep compressed air storage cavern in a complex metamorphic environment. The exploration process involved drilling using HQ-3 coring techniques from surface and also from an adjacent underground mine. The latter were two 460 m boreholes drilled just sub horizontally across the planned cavern location. \nThe core from these holes was logged for structure and sampled for rock property testing. Because a significant portion of the rock was highly anisotropic the test methods used had to be adapted. This included alternative ways of working with point load testing\, triaxial testing for anisotropy of moduli and some special shear tests.  Because of the importance of determining potential leakage of groundwater into the cavern\, or of air out of the cavern\, the correct measurement of the ground fluid pressure and the permeability of the rock mass were extremely important. \nTesting had to be conducted in stages to cover the entire length of the holes. The method used was to fit the drill rods with a straddle packer assembly\, downhole valve system and suitable precision pressure monitoring with operator read out. First the test zone was shut in to recover pressure. This was followed by a period of injection or production which was followed by another shut in period. These tests followed oilfield practice but with tools designed to work with HRQ drill rod and used horizontally. \nThe rock stress was determined by the use of three dimensional overcore tools used up to 441 m laterally. Other techniques could have also been advantageously used to fill in the sparse overcore data in the extremely complex geological environment. The vertical and the horizontal holes were logged using both acoustic televiewer and full wave sonic sondes. \nThe conclusions of the study were that the rock mass was heterogeneous but fit for purpose provided that the correct design decisions were made. The presentation also looks at what can be achieved from open hole drilling test techniques compared to coring and the comparative costs of these. This has particular relevance to tunnel investigations. \nProgram timeline\nOnline \n6.00pm – Presentation commences \n7.00pm – Presentation concludes \nIn-Person \n5.30pm – Registration\, networking & catering \n6.00pm – Presentation commences\, networking \n7.00pm – Event concludes \nLearning outcomes\n\nYou should gain an appreciation of the importance of geology.\nYou will gain an understanding of the methods used to determine the states of stress in rock and the measurement of anisotropic rock properties.\nThe methods used and the importance of determining fluid pressures and permeability properly are extremely important and should totally replace conventional packer testing.\n\nAbout the speaker\n\n\n\nIan Gray\nManaging Director\, Sigra Pty Ltd\n\nDr Ian Gray is the managing director of Sigra Pty Ltd\, a role he has held for 32 years. In his career he has had the roles of mining\, civil\, geotechnical and reservoir engineers\, engineering geologist and hydrogeologist.

SUMMARY:Choosing the right VSD for tunnel ventilation application
DESCRIPTION:Overview\nIn recent years\, several tunnel projects have faced serious setbacks due to catastrophic motor failures. These failures are caused by high peak voltages\, a result of using Active Front End (AFE) VSDs combined with long motor cable lengths\, extending to 500 meters. This session examines the underlying electrical phenomena contributing to these issues and why conventional mitigation methods\, such as standard filters\, are often insufficient. \nParticipants will gain practical insight into proven engineering solutions that deliver near-sinusoidal voltage at the motor terminals\, reducing stress on insulation and extending asset life. Drawing on real-world case studies and field testing\, the session highlights key design considerations\, specification pitfalls\, and lessons learned to support more reliable tunnel ventilation system performance. \nLearning outcomes\nIn this event\, attendees will be able to: \n\nidentify the root causes of high peak voltages in AFE VSD tunnel applications\nevaluate why conventional filtering methods may not adequately protect motors apply practical design and specification strategies to prevent premature motor failure\nselect VSD and mitigation solutions that improve reliability and extend asset life\n\nProgram\nIn-person: \n\n5.00 pm AEST: Guest arrivals and registrations\n5.30 pm AEST: Presentation begins\n6.15 pm AEST: Q/A begins\n6.30 pm AEST: Event close\n\nOnline: \n\n5.30 pm AEST: Presentation begins\n6.30 pm AEST: Presentation ends\n\nAbout the speakers\n\n\n\nJoris Feekman\nRegional Sales Manager\, Danfoss Drives\n\nJoris is Regional Sales Manager at Danfoss Drives\, with over 25 years of experience in electrical drives and industrial power conversion.

SUMMARY:Site visit: fire suppression condition monitoring at AirportLink
DESCRIPTION:Overview\nRoad tunnels have design lives of 50-100 years\, with Mechanical\, Electrical and Fire assets having design lives of only 5-25 years. Managing deterioration that triggers changes in condition and performance is essential to enable the fire safety strategy defined in the Fire Engineering Report\, as well as to identify need for amending it as both technology\, technical and legal requirements change. This presentation will present a project in which the condition of the combined fire mains in an established road tunnel (AirportLink) was assessed through non-destructive techniques (NDT) to inform the asset manager of the expected service life remaining\, which in turn informs both short- and long-term investment. The presentation will be followed by a visit to the tunnel during a maintenance closure to discuss some of the drivers and challenges of the project arising from the available maintenance windows and the physical layout of the system. \nThis site visit is targeted primarily towards young engineers\, however we do welcome all engineers. \nProgram timeline\n6.30pm – Registration\, safety check and brief introduction. \n7.30pm – Fire mains condition assessment presentation \n9.00pm – Maintenance toolbox \n10:30pm – Tunnel closes for access \n10:45pm – Group tunnel walk \n12:30am – Group exits tunnel and wrap up \n1:00am – Site visit concludes \nThis site visit concludes after midnight and the timetable may be subject to change depending on traffic conditions. \nMinimum PPE requirements\nAttendees are required to have full PPE for participation\, including: \n\nLong Trousers – 2 Reflective Stripes\nLong Sleeve Shirt – Reflective Stripes\nClear Safety Glasses\nHard Hat (in Date)\nGloves\nLaced Up Steel Capped Boots (Secured & Fitted)\nHearing Protection\n\nAttendees that do not comply with the minimum PPE requirement will not be admitted on the day. \nPlease Note: Mandatory alcohol testing and random drug testing will be conducted upon arrival.  \nAbout the speaker\n\n\n\nJaime Cadena Gomez\nPrincipal Engineer\, Fire Safety\n\nJaime Cadena Gomez is an engineering professional with 17 years of experience understanding and managing operational risks and performance of critical infrastructure.

SUMMARY:Geotechnical Baseline Reports in Australian Collaborative Contracting: Legal and Engineering Perspectives
DESCRIPTION:Join us for this ATS and Australian Geomechanics Society (AGS) Joint Seminar\nSeminar abstract: \nAustralian infrastructure procurement is undergoing a fundamental shift toward collaborative delivery models\, such as Alliance contracts\, ECI frameworks\, Progressive Design-Build\, and ITC arrangements. These models demand a fundamentally different approach to Geotechnical Baseline Reports (GBRs) than is required under traditional Design-Bid-Build contracts. \nThis seminar brings together legal and geotechnical expertise to examine how GBRs function in contemporary Australian practice. From the legal perspective\, the presentation explores GBR structures as they are incorporated into various construction contracts across Australia\, examining risk allocation mechanisms\, drafting precision\, and dispute resolution frameworks. From a geotechnical engineering perspective\, the speakers touch on distinguishing GBRs from traditional investigation reports by covering ground model development\, physical and behavioural baselines\, and the critical importance of multidisciplinary authorship. \nDrawing on domestic and international lessons\, from adversarial “you bid it\, you build it” approaches to modern risk-sharing frameworks\, the speakers look into what differentiates collaborative from traditional GBR practice. Topics include authorship models\, treatment of uncertainty through provisional baselines\, and practical application to Melbourne’s geological challenges. \nAustralian practitioners risk repeating costly mistakes made elsewhere. This seminar equips geotechnical/tunnelling engineers\, project/commercial managers\, and client staff with the knowledge to implement effective GBR practices suited to Australia’s evolving contractual landscape. \nDate and Program: \n28 April\, Tuesday\, 2026. \n\n17:30 Attendees’ arrival and networking\n18:00 Intro and Presentation\n18:50 Q&As followed by promotions on subsequent events\n19:00 Networking\n19:20 Close\n\nLocation \nThe University of Melbourne\, Brown Theatre (106)\, Level 1\, Electrical & Electronic Engineering Building (Building 193)\, Parkville \nhttps://go.unimelb.edu.au/bew8 \nPresenter’s bios: \n \nJames Morgan-Payler \nJames Morgan‑Payler is a Partner and Head of Asia Pacific at international law firm Pinsent Masons.

SUMMARY:Design of High-Performance Rock Bolted Thin Shotcrete Linings
DESCRIPTION:Design of High-Performance Rock Bolted Thin Shotcrete Linings\nFrom Basics to Advanced Concepts\nOverview\nTunnels in poor to fair-quality rock masses (i.e. Q-values between 0.4 and 10) can generally achieve global stability and ground support primarily through ground reinforcement\, such as rock bolts. Such reinforcement elements not only hold unstable rock wedges and blocks but also provide local shear and tensile reinforcement where they cross rock defects or discontinuities\, enhancing the rock mass’s capacity to redistribute stresses during tunnel excavation more safely. However\, to keep costs down\, rock bolt spacing must also be efficient; as a result\, the use of a surface retention system\, such as shotcrete\, is still necessary to promote local stability and stress arching\, thereby supporting the rock mass between the rock bolts. In these cases\, a thin shotcrete lining (75-150 mm thick) is often used. It is usually designed to span the loads between the rock bolts\, accounting for both flexural and punching failure mechanisms. When combined with long cables\, as it is frequently used in mining\, the system can also play a greater role in global stability\, reducing the risk of larger failure mechanisms with volumes of the order of the excavation. It can\, in principle\, also be designed for dynamic loads if the bolts are designed for them. This presentation will discuss some basic concepts of this support system\, including the use of fibre reinforcement\, and then move on to more advanced concepts\, such as compressive membrane action and non-linear concrete design. \nSpeaker\n\n \n\nDr David Oliveira \nDiscipline Leader\, Ground\, Aurecon \n\n\n\nDr David is a Chartered Professional with 27 years of experience in civil engineering and mining geomechanics. He is Aurecon’s Discipline Leader for Ground Engineering\, including the Geotechnical\, Geology\, Tunnels\, Underground Structures and Pavements teams. He is also currently the Vice-Chair of Working Group 12 – Sprayed Concrete of the International Tunnelling Association. Besides major recent infrastructure such as Westconnex M8\, Westconnex M4-M8\, Hinkley Point C Nuclear Power (UK)\, Sydney Metro West-Central Tunnelling Package\, Western Harbour Tunnel Package 2\, and Borumba Pumped Hydro\, David has worked in projects for some deep underground mining projects such as Gwalia Mines (AU)\, Big Gossan (Indonesia)\, Cuiaba Mine (Brazil) and currently Oyu Tolgoi (Mongolia). \n\n\nThis event is run by the Australian Geomechanics Society in collaboration with Western Australian Ground Control Group and Australian Tunnelling Society. \n\n\n

SUMMARY:High speed rail tunnel aerodynamics
DESCRIPTION:Overview\nThe webinar will focus on the aerodynamic phenomena and effects associated with the high-speed passage of a train through a tunnel. We will begin by describing the pressure waves generated as a high-speed train enters a tunnel\, passes through changes in tunnel geometry\, crosses another train and exits the tunnel. Their generation\, propagation\, reflection\, and transmission will be discussed. Airflow patterns induced inside the tunnel\, influenced by blockage ratio\, tunnel geometry and train speed\, will also be presented. \nIn the second part\, we will examine the impact of these pressure waves on passenger tympanic comfort and safety\, both on the platforms of underground stations and on board high-speed trains. Their effects on tunnel equipment\, such as ventilation systems and platform screen doors\, as well as on the trains themselves\, will also be addressed. Finally\, we will discuss aerodynamic drag and the factors that help reduce it\, including the construction of pressure relief shafts or the creation of a partial air vacuum. \nThis will lead us to conclude with a brief exploration of the hyperloop concept. The presentation will be supported by experimental results and numerical simulations based on real world case studies. \nLearning outcomes\nIn this event\, you will: \n\nhave an appreciation of the aerodynamic challenges experienced in a high-speed rail tunnel environment and what measures should be taken during the design and construction of such systems\nobtain a good overview of different systems that are affected and will give the audience a general understanding of the problem.\n\nProgram\n\n5.30 pm AEDT: Presentation begins\n6.30 pm AEDT: Presentation ends\n\nAbout the speakers\n\n\n\nMichele Mossi\nPresident\, CEO and Founder\, GESTE\n\nMichele Mossi (born 1970) is a physicist and engineer who graduated from the Swiss Federal Institute of Technology in Lausanne (EPFL)\, where he also earned a PhD in aerodynamics.
