Gedinne Tower - 99.032


Complete mission for civil and structural engineering.


The 'Domaine de la Croix-Scaille' observation tower shows a panoramic view of its 9000ha forest. The tower consists of 600 year old Douglas fir tree trunks that were offered by the Gedinne village council. Thee tree trunks are linked with ties and form in this way a double tripod. To provide access to the platforms an independent stair shaft is placed. Inside the shaft is a double helicoidal stair. Above each platform a membrane structure offers the visitors shelter from the weather. The total tower weighs 80 ton.

Due to the difficult accessibility to the building site for heavy assembly cranes, the tower is erected around two supports. The entire operation took place on august 28 2001 and took less than eight hours.
