Transport infrastructure
Transport infrastructure’s reliability begins underground, and geotechnical services are essential for designing, constructing, and maintaining roads, railways, bridges, tunnels, ports, and airports.
These services ensure every element of transport infrastructure is supported by stable ground conditions, optimised earthworks, and resilient foundations, no matter the terrain or environmental challenge.
From early feasibility studies to long-term asset management, geotechnical input helps deliver infrastructure that is safe, durable, and cost-effective.
Key geotechnical services include:
Site investigations and terrain evaluation
- Subsurface investigations using drilling, sampling, and in-situ testing
- Mapping soil and rock profiles to guide alignment and foundation decisions
- Identifying geohazards such as soft soils, sinkholes, or reactive clays
Earthworks and embankment design
- Optimising cut-and-fill operations for roads and rail corridors
- Designing stable embankments and slopes with erosion control measures
- Verifying compaction and fill quality through field testing
Pavement and subgrade engineering
- Assessing subgrade strength and moisture sensitivity
- Designing pavement thickness and materials for long-term performance
- Rehabilitation strategies for aging or distressed road surfaces
Bridge and tunnel foundations
- Deep foundation design for piers, abutments, and tunnel portals
- Settlement analysis and load-bearing capacity evaluations
- Ground improvement techniques for challenging soils
Slope stability and landslide risk
- Stability modelling for cuttings, embankments, and natural slopes
- Monitoring and mitigation of slope movement in hilly or flood-prone areas
- Design of retaining structures and rockfall protection systems
Drainage and groundwater control
- Designing subsurface drainage systems to protect pavements and structures
- Groundwater modelling for tunnel dewatering and flood resilience
- Managing seepage and hydrostatic pressures in low-lying zones
Transport infrastructure endures heavy loads, dynamic forces, and environmental extremes.
Our geotechnical services deliver the insight and engineering knowledge required for project owners to be confident that every bridge span, rail track, and highway lane is supported by ground conditions that have been thoroughly understood and appropriately managed.
