Extreme Constructions

It's a major construction project, aimed at doubling the width of the Suez Canal and deepening its main waterway. 500 million cubic meters of sand and soil have already been transported from all over the world. Using unprecedented 3D images, we reveal how the canal will be widened. We also look back to the original construction, back in 1859, to show how it first came to be built.

More than a century old, Paris' metro is the beating heart of the city. With its 220 km of rail, 302 stations and 13 lines, the metro transports more than five million people every day. The Parisian Metro tested many construction methods: wooden tunnels, boring machines, shields, ground freezing systems, steel viaducts and submerged chambers in the Seine.

315 metres long, 65 metres high, weighing 80,000 tonnes and capable of transporting more than 7,000 people, the Meraveglia is the ultimate cruise ship. But how was she built? We followed her development at the St. Nazaire construction site, a building ground for the world's biggest vessels.
