The pouring is a continuous operation thanks to the sliding formwork methodology, which allows a progress of around 15 centimeters per hour.

Eiffage Génie Civil Marine will produce 21 concrete caissons with impressive dimensions: 54,5 m long, 28 m width, 32 m high.

Those caissons will constitute the protective dyke to the swell of the GTA project for BP and partners over a length of 1,2 km.
