The Austrian Steel Construction Award 2019 was presented to both the structural engineering firm KonstruktING GmbH and the architecture firm 4juu architekten for their collaborative design of the project.
Structure
The pedestrian bridge has a total length of 22.7 m (74.5 ft) with a free span of 15.34 m (50.33 ft). The top and bottom truss chords consist of solid steel bars 5 mm x 100 mm (0.20 in x 3.94 in). The truss web members are round steel bars 18 mm (0.71 in) in diameter, arranged between the chords at varying angles and spacing. Depending on the force distribution along the structure, additional web members are placed at necessary locations. The round bars are arranged in four planes, which increase the transverse stiffness.
A thin deck of flat bars and channel sections spans the bottom chords. The hardwood plank flooring is further placed on top of the deck. The pedestrian bridge widens to a Y-shape at the garden entrance. The garden toolshed is integrated at this location.
Due to the low material costs, the pedestrian bridge is an ecologically optimized structure that integrates seamlessly with the surrounding area.
