The fist shells for the habited silos are out of the factory and have been presented to us by Hanny, who has been given that job by TPI.
These large concrete shells of about 12m by 3m and 15 tons each have been cast in wodden shapes specially constructed for the project in the Vosges area.
The polygonal opennings have been designed in 3D in the office. They have many tempered angles and must, wherever they appear in the curve, drain water as well as wistand important structural forces.
