The form of the new watch tower is based on the structure of a double helix. Two strands wind endlessly one around another and spiral upwards. This geometric form forms the supporting structure and integrates at the same time the double wound stairs: the observation platform is part of the route and connects the two flights of stairs. The supporting structure is designed as hybride structure: a combination of rigid nodal-intersections and additional stranding and pressure bars. The primary structure with supporting and support tubes operates as spacially coherent frame structure and provides stability whereas the vertical stranding controlls the vibration behaviour and the diagonal upwards winding cables controll the oscillation of the head of the tower. Due to this disposal of the cables no additional vibration dampers are necessary. The angles of the double helix are the intersections of all supporting items and constitute the arraying principle of the seemingly chaotic construction. The profile of the girders taper according to the static needs towards the top and provide the filigree appearance of the building.
