Tunnel Systems
Protecting life below ground starts with systems that work — every time
Tunnel systems do more than support infrastructure — they protect people. Ventilation, fire and life safety, drainage, supervisory control and data acquisition (SCADA) controls and mechanical electrical plumbing (MEP) systems work together to manage risk and keep tunnels operating safely in both everyday conditions and emergencies.
When these systems perform, communities move confidently. When they don’t, the consequences are serious. That’s why performance isn’t optional — and must be engineered from the start.
At Jacobs, we design and validate tunnel systems that perform when it matters most — across the entire asset lifecycle. From safety analysis and fire and smoke modeling to code-compliant design, testing and commissioning, we assist teams overseeing new and existing tunnels — including complex high-speed rail systems — meet regulatory requirements and operate with confidence.
Tunnel Engineering Solutions
Safe, buildable tunnels start with understanding uncertainty — and designing for it.
