Tunnels and underground structures form an increasingly important part of modern-day infrastructure. This infrastructure provides economic, societal, and environmental benefits through the facilitation of the efficient and rapid movement of people below-ground. This may be in mass transit systems, high-speed rail lines or in highway tunnels.

As a tunnel ventilation engineer, you will design and analyse tunnel ventilation systems for both normal and emergency operations. You will also assess the related elements such as fire and life safety systems following client specifications and worldwide standards. You will work on a range of underground facilities and tunnels, including metro systems, railway stations, road tunnels, cable tunnels and more.

• Planning, designing and installing ventilation systems for tunnel projects.
• Working on a range of systems to ensure tunnels are safe.
• Planning and overseeing commissioning, operation, refurbishment, and upgrade of tunnel infrastructure.
• On-site inspection and performance testing of tunnel ventilation systems.
• Applying fluid mechanics and thermodynamics for fire and ventilation modelling.
• Implementing fire safety engineering, risk analysis and evacuation analysis.
• We are looking for good experience in engineer in road and rail tunnel ventilation design, fire and life-safety design, gained in road, rail and/or metro tunneling schemes.
• Excellent technical skills and numeracy skills acquired during your academic background. Understanding of fire dynamics, heat transfer and smoke behavior principles in enclosed environments.
• Advanced user of 1D design tools such as IDA for Road and SES for rail. Computational Fluid Dynamics modelling and visualization using programs such as FDS, Pyrosis and Smoke view or others.
• Movement Modelling Analysis evacuation and crowd simulations using computational models such as Pathfinder.
• Up to date knowledge of current legislation and standards applicable in tunnel ventilation design.
• Demonstrating technical expertise, providing in depth knowledge whilst proactively coaching and developing graduate/early career professionals.
• High motivation to succeed, and to progress and develop your career. Personality compatible with a high degree of collaborative and teamwork in multi-disciplinary and international projects.
• Communication and writing skills which can produce clear and concise reports or presentations. Willingness to travel on short assignments within the UK and overseas for dealing with challenging projects or participation in reputed conferences.
