@weekend_75officiel: This miniature model demonstrates bridge foundation construction using a steel caisson. A crane lowers the caisson into the water and seabed, where it is positioned through layered soil until reaching stronger bearing material. Concrete can then be placed inside to form a massive underwater foundation for a bridge pier. #fblifestyle #Engineering #CivilEngineering #BridgeConstruction #CaissonFoundation
