What EDG Consulting does

EDG Consulting Pty Ltd is a privately held Australian geotechnical engineering consultancy founded in 2015 by Ian Shipway, Garth Powell, and Greg Hackney, headquartered in Fortitude Valley, Brisbane with a second office in Collingwood, Melbourne. The firm provides professional engineering, engineering geology, and design services across the full project lifecycle — from feasibility and site investigation through detailed design to construction-phase support and decommissioning — to government agencies, tier-1 contractors, and private developers in Australia.

Its core technical platform is the Engineering Geological Model (EGM) development methodology, a systematic approach to collating and interpreting geological and geotechnical data into a site model that informs all subsequent design work. The firm executes this using established numerical-modelling software (Plaxis 2D/3D, RS2, Slope/W, Slide2/3, RocFall, Wallap, Settle3, GINT) combined with in-house design tools developed from first-principles geotechnical theory. Service areas span temporary works design, slope engineering and rockfall risk, foundation design, dam and tailings engineering, soft soil engineering, deep excavation retention, and forensic/expert witness work.

EDG operates as a specialist subcontractor on major Australian infrastructure programs (Cross River Rail, West Gate Tunnel, Level Crossing Removal Project, Sunshine Coast Airport Expansion, Sarina Range Reconstruction, Upper Yarra Dam Safety Upgrade) and holds direct appointments with state transport authorities (TMR Queensland, Queensland Rail, NSW Transport, VIC Roads). Revenue is project-based professional services fees. In 2023, TYPSA Group, a multinational engineering consultancy, acquired a controlling interest to scale the business while retaining founding principles, providing a pathway to international project delivery across TYPSA's global footprint.

Product overview

EDG Consulting is a geotechnical engineering consultancy that provides a unified suite of professional services rather than a modular software product. The company offers engineering advice and geotechnical design across the project lifecycle—from feasibility and design through construction to decommissioning. Core service offerings include geotechnical site investigation, geological modelling and interpretation, geotechnical risk assessment and risk management, soft soil engineering, geomaterial assessment and earthworks design, slope engineering, retaining wall and retention system design, foundation design, tailings and water storage dam design, temporary works design, construction phase services and monitoring, and forensic investigations and expert opinion. These services are delivered to private, public, and government clients across market sectors including transport infrastructure, mine infrastructure, mining and dams, ports and harbours, development and buildings, and legal sectors. The company operates from offices in Brisbane (QLD) and Melbourne (VIC), Australia.

Products and services

• Geotechnical Site Investigation Comprehensive geotechnical site investigation services for infrastructure projects, providing ground characterisation and data to inform engineering design across feasibility, design, and construction phases. Delivered to infrastructure contractors, government agencies, and private developers.
• Engineering Geological Model (EGM) Development Systematic process of gathering and collating geological information and interpreting geotechnical data to build a site model relevant to project engineering, defining characteristics, identifying uncertainties, and targeting specific testing requirements. Market-leading expertise applied to all EDG projects.
• Temporary Works Design Leader in geotechnical temporary works design including slope stability assessments, excavation retention systems (soil nails, piles, sheet piles, retaining walls, anchors), foundations for tower cranes and scaffolding, cofferdams, and working platforms for piling rigs and cranes. Delivered to tier-1 contractors on major infrastructure projects.
• Geotechnical Risk Assessment Qualitative and quantitative risk assessments using RMS Slope Risk Assessment methodology, Australian Geomechanics Society Guidelines, and first principles approaches for risk to life calculations. Includes 3D mapping and visualisation tools and rockfall modelling software. EDG has four fully accredited RMS/TMR slope risk assessors.
• Dam Engineering Services Complete range of dam engineering services from geotechnical site investigations to detailed design, including seepage and stability modelling, liquefaction assessment, construction materials assessment, and hazard identification and risk assessment including failure modes assessment. Applied to tailings dams, water storage dams, weir structures, and dam safety upgrades.

Direct peers

• Tonkin + Taylor: New Zealand-headquartered specialist geotechnical and environmental engineering consultancy with operations across Australasia. Closely comparable in size and specialisation, particularly in transport infrastructure, dams and slope risk assessment work.
• SMEC (Snowy Mountains Engineering Corporation): Australian-origin engineering consultancy now owned by Surbana Jurong, with strong presence in transport infrastructure, dams and geotechnical work. Comparable regional peer that EDG would compete against for transport authority panel positions.
• Coffey International (Tetra Tech): Historically leading Australian geotechnical and engineering geology consultancy (Ian Shipway was Senior Principal at Coffey for seven years). Now part of Tetra Tech, serving the same Australian infrastructure, mining and dams markets with the same geotechnical specialisation.
• Aurecon: Australian-headquartered engineering, design and advisory firm operating across transport infrastructure, dams, mining and buildings. Directly comparable as an Australasian consulting peer competing for the same major infrastructure tenders and sharing pre-qualifications across state transport authorities.
• BG&E: Australian engineering consultancy delivering civil, structural, geotechnical and temporary works services to transport and building infrastructure clients across QLD, NSW and VIC. Comparable in size, sector mix and specialisation in temporary works and slope engineering.

Broad incumbents

• Stantec: Global engineering, consulting and project management firm with an Australian transport infrastructure, water and environmental practice. Competes for the same tier-1 contractor and government panel work and offers bundled services that can displace specialist subcontractor positions.
• AECOM: Global infrastructure consulting firm with major Australian transport, dams and mining infrastructure practices. Competes for prime consultant roles on the same programmes EDG supports (e.g., Cross River Rail, West Gate Tunnel) and can absorb specialist geotechnical scopes.
• Arup: Global engineering consultancy with significant Australian transport infrastructure practice (Tim Thompson spent 18+ years at Arup before joining EDG). Competes directly for major transport tenders and geotechnical risk assessment mandates across EDG's geographies.
• WSP (including Golder): Global engineering consultancy with deep Australian operations in transport infrastructure, geotechnical and environmental services following the Golder acquisition. A broad incumbent that competes for both prime consultant and specialist subcontract roles, particularly in QLD, NSW and VIC infrastructure.
• Mott MacDonald: Global engineering consultancy with strong Australian transport, rail and dams practice. Competes for major infrastructure programmes that EDG supports as a specialist subcontractor and is also capable of providing in-house geotechnical capability.
