What Is Critical, Yet Generally Goes Unnoticed?

Tunnels transform transportation networks by linking nations, uniting communities, and reducing travel time. Water and wastewater tunnels make modern hygiene and sanitation standards possible. Utility tunnels bring us electricity, telephone, internet, and gas pipelines, powering our lives. Underground spaces contribute to our transit networks, our energy reserves, and our scientific research. Tunnel design and construction requires a wide range of engineering skills to deliver innovative solutions.

Bringing together all required disciplines under one roof, WSP is a world leader in tunnel planning, design, rehabilitation, and construction. From pre-feasibility, through fire and risk engineering and ventilation systems, to post-maintenance, we offer in-depth expertise throughout the tunnel lifecycle.

Our hands-on experience includes all types of tunnels—rock, soft ground, cut-and-cover, immersed tunnel, micro/trenchless, and the New Austrian tunneling/sequential excavation method. Our engineers have worked on a wide variety of underground construction projects around the globe, from road tunnels and subway stations, to underground nuclear waste repositories and water conveyance systems.
