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.

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.

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.

We’ve also started using 3D printing for custom solutions\, and we’ll share practical lessons on what actually works in the field. \nNavigation technology has advanced considerably for roadheaders and bolters. Sandvik’s Cutronic and TRO systems are making tunnelling safer and more precise\, while improvements in visualisation and PTT management help operators work more effectively. Bolter systems have matured with auto-bolt selection\, and web-based platforms now make data far more accessible. \nThe robotics in construction space is showing interesting possibilities. We’ve provided positioning for equipment like ROBY\, Paneller\, and Wall Shaver\, though it’s still early days. There’s growing discussion about designing construction processes with robotics in mind from the start. \nWe’ll walk through these topics with real project examples and lessons learned along the way. \nTimings\n5:30pm  Light refreshments \n6:00pm  (AEST) Main Presentation \n7:00pm  Discussion and Drinks \n7:30pm  Event Conclusion \nSpeaker\n \nSteven Garlinge \nManaging Director\, Geodata KODA Australia \nSteven Garlinge has worked in Sydney’s tunnelling industry since 1998\, starting as a cadet engineer in the Elgas Storage Caverns.

The project uses two approaches: two 15.1-metre-diameter Tunnel Boring Machines for the main drives\, and the Sequential Excavation Method with roadheaders for the more complex sections. Working through highly variable ground conditions in a busy urban area has required innovative solutions at every stage. The presentation covers the challenges the team has faced and how they’ve addressed them—from adapting excavation methods to suit different ground conditions\, managing tunnel portals in sensitive locations\, and using advanced monitoring systems that track progress and ground movements in real time. You will also hear how digital engineering and Building Information Modelling have improved both efficiency and safety on site\, as well as how the project balances major construction work with minimising impacts on surrounding communities. This session offers practical lessons from a significant Australian tunnelling project and a chance to discuss approaches relevant to your work. \nTimings\nIn person: \n\n5:30 PM Welcome and Networking\n6:00 PM Presentation\n6:45 PM Q&As and post presentation networking\n\nBeverages and refreshments will be provided. \nOnline: \n\n6.00 pm meeting and technical presentation\n7.00 pm event ends\n\nSupporter\nThis event is supported by ARUP.
