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. Currently\, he is the Principal Asset Engineer for Fire Safety across a network of 16 road tunnels in Australia.

SUMMARY: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.
