Richard Hammond embarks on a global adventure to explore the world's biggest structures and machines and discover how engineers build, maintain and use them.

Each episode of Extreme Engineering features a major construction and engineering project. Some projects are completed ones, like the new Hong Kong airport. Other projects are those under construction like the Gotthard Base Tunnel under the Alps. Still other episodes showcase futuristic projects that may never be built, like the Transatlantic Tunnel. Most episodes examine possible disaster scenarios that could threaten the projects.
