Engineering Consulting
Multi-disciplinary engineering, analysis and digital delivery for complex underground assets.
Our engineering consulting services include geotechnical engineering, structural engineering, computational engineering and analysis, pipeline engineering, design technology and digital engineering, civil and architectural design, sustainable design and construction, and risk assessment and mitigation.
With a team of innovative, creative and problem-solving professionals, we craft engineering solutions that take into account project economics, contractual obligations and the practical aspects of construction — because a design that cannot be built is not an engineering solution.
Disciplines
- Geotechnical engineering and ground modelling
- Structural engineering of tunnels, shafts and stations
- Computational engineering and numerical analysis
- Pipeline and pressure tunnel engineering
- Design technology, BIM and digital engineering
- Civil and architectural design
- Mechanical, ventilation and fire/life safety
- Hydrogeology and engineering geology
- Sustainable design and construction
- Risk assessment and mitigation
Digital delivery
- Common Data Environments for live projects
- Federated model coordination across disciplines
- Parametric tunnel and shaft modelling
- Computational mesh and analysis automation
- Design issue and constructability clash review
- Digital handover and asset data
Engineering approach
- Performance-based design where standards stop short
- Design for constructability as standard practice
- Seismic and extreme-event resilience
- Whole-life cost considered at concept stage
- Independent design review and checking
This service, in practice.

Talk to the engineers who do the work.
Every enquiry is reviewed by a principal engineer in the relevant practice — not a sales team. If your question is a technical one, you will get a technical answer, and if we are not the right firm for the job, we will say so.
