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. He is a leading adviser on the structuring\, preparation and negotiation of construction and project contracts across major Australian and international infrastructure and energy developments. \nJames has extensive experience advising on collaborative and complex delivery models\, including Design & Construct (D&C)\, Early Contractor Involvement (ECI)\, Alliance contracting\, EPC\, O&M and Public‑Private Partnerships (PPPs). His practice spans a wide range of major projects\, including wind\, solar\, hydro and gas power generation assets\, desalination plants\, social infrastructure\, and large-scale road and rail developments. \nIn this presentation\, James will focus on the legal foundations\, risk allocation and contractual treatment of Geotechnical Baseline Reports within contemporary Australian collaborative contracting models\, providing a legal perspective to complement the technical and geotechnical insights presented alongside him. \n \nDr Jay Lee \nDr Jay Lee is an experienced geotechnical engineer and project leader with extensive involvement in the delivery of major infrastructure projects across Australia\, Asia\, and North America. He has worked on complex building and infrastructure works\, including marine facilities\, roads\, railways\, and underground structures. \nDr Lee brings strong technical expertise in geotechnical/tunnelling engineering\, combined with practical experience supporting constructability\, ground‑risk management\, and collaborative project delivery. He has also contributed to research and development initiatives focused on advancing geotechnical practice and innovative construction methodologies. He is particularly experienced in working at the interface between clients\, designers and contractors to resolve technically complex ground‑related challenges and to improve constructability outcomes throughout the project lifecycle. \nIn this presentation\, Dr Lee will provide the technical and engineering perspective on Geotechnical Baseline Reports\, complementing the legal insights presented alongside his co-presenter. \n

SUMMARY:Testing of sprayed fibre reinforced concrete for the design of tunnel linings
DESCRIPTION:Overview\nFibre reinforced concrete (FRC) design has been widely used for sprayed permanent linings in tunnels with substantial recent developments in design methods and mix design. One such development has been reliance on the toughness characteristics to inform the design versus the different methods of panel testing. This presentation discusses the 2025 fib bulletin 116 recommendations with a focus on testing and performance criteria. By adopting EN 14488-3 procedure for the toughness characterization of the sprayed FRC\, it is possible to derive the key parameters that are necessary for the design according to fib Model Code 2010 in an easy quantifiable manner. \nLearning outcomes\nIn this presentation\, you will: \n\nunderstand the advantages and drawbacks of various shotcrete testing methods\nunderstand the importance for shotcrete testing to directly relate to design methods\ngain an insight into the latest shotcrete testing methods.\n\nProgram\nIn-person: \n\n5.30 pm AEST: Registrations open\n6.00 pm AEST: Presentation begins\n6.45 pm AEST: Q&A session\n7.00 pm AEST: Networking\n8.00 pm AEST: Event ends\n\nAbout the speaker\n\n\n\nCheng Chian Gan\nTechnical Manager\, Underground Solutions – Bekaert Singapore\n\nGan is an expert in sprayed fibre reinforced concrete with over 35 years of civil engineering experience. He is a member of the Working Group on SS674-2021 since Jan 2019. Gan is a domain Expert for Sprayed Concrete and Fibre Reinforced Concrete under Intelligent National Productivity and Quality Specification Singapore since Mar 2019. From 1998 to present\, Gan has been involved in over 22 sprayed fibre concrete tunnel linings and over 20 fibre concrete precast segmental and cast concrete tunnel lining projects.
