capricorn bridge - a 35m long steel-and-glass structure

FLOAT, an office building designed by architect Renzo Piano, was built at the southern end of Dusseldorf’s so-called “Medienhafen” (media harbour). This building is now to be connected to the “Capricorn” building across the street by a spectacular steel and glass pedestrian bridge.

The bridge structure, with a total length of 35m, consists of a closed, tubular grid shell with glazing made of approx. 60 trapezoidal and triangular insulated glass units (up to 8.1 x 3.0m). The kink in the bridge, evident in the horizontal section, ensures an exact connection to both buildings. The loads of the bridge are absorbed solely by means of the steel structure in the glazed middle column. 

  • Since the two cantilevered bridge arms to the left and right of the column have different lengths and angles, the structural design is correspondingly complex. seele convinced the project participants with a design assist and is currently executing the main contract scope.

Start of assembly of the Capricorn Bridge in Dusseldorf.

A grid shell made of eight polygons, longitudinal ribs and diagonals forms the body. Over the next four weeks, the various parts will be joined to form two completely self-supporting bridge arms and a central pylon.


The steel substructure consists of a central pylon and 2 bridge arms. The central pylon consists of 13 round columns. The base of the pylon, the so-called foot element, will be delivered to the construction site in one piece in a size of 8 x 3m and will be encased in conrete. Absolute precision is required, because every millimetre is decisive for assembly on the construction site.
