We offer design, planning, and measurement services for all types of major underground infrastructure including road, rail and cable tunnels, and underground rail and bus stations. Through our experience and appreciation of civil, structural, construction, and operational constraints, we develop practical and cost-effective tunnel ventilation designs. Stacey Agnew works collaboratively with operators, designers and constructors, as well as providing advisory services to regulators and owners.
Our specific local and overseas
project experience includes:
- Engineering design and documentation of tunnel ventilation plant for air quality, normal operating heat and fire (smoke).
- Test and measurement including aerodynamic and thermodynamic assessments, data acquisition and analysis, and experimental validation of simulations.
- Dynamic simulation of airflow and pollution in road and rail tunnel networks to provide certainty in design outcomes.
- Smart control system design, coupling dynamic modelling of the tunnel aerodynamics with control algorithms including state-of-the-art predictor strategies.
- Engineering design and scheme assessment of normal operation and emergency systems.
- Design optimisation for minimising installed infrastructure and reducing operational energy costs.
- Algorithms for predicting vehicle emissions.
- Stack dispersion and near-field air quality including assessment of portal emissions using computational fluid dynamics (CFD).
- Ventilation design for tunnel construction (mining and major temporary surface infrastructure for fume and dust control, and emergency management).
- Risk assessment and fire life safety design.
