The concrete specialist stayconcrete was commissioned by the Luxembourg communal building authority to realize an unusual concrete project: two paper planes, cast in concrete, based on the design of Serge Ecker. Every plane measures 4.5 x 3.1 meters and weighs a remarkable 2.5 tons. A small but weighty challenge in terms of production technique and logistics, which now invites you to contemplate and linger in front of the Lycée Hubert Clément in Esch-sur-Alzette (Luxembourg).
The idea behind it: paper planes are a typical science project for pupils – and as planes made of concrete, they are meant to fly graduates symbolically into the world and into an exciting future.
Figures: View of both concrete planes in front of the Lycée (1); view into the production hall of stayconcrete (2); tricky: concrete cannot be folded like a paper plane, but must be cast. Here is the casting mold (3).
