Fransman Footbridge

Fransman Bridge is a sculptural steel bridge characterized by its sweeping, three-dimensional form and integrated structural elements. Its construction combines curved side panels, floor plates, ribs, longitudinal stiffeners, and handrail components into a complex steel structure. The complete building package comprised approximately 658 square meters of steel and had an estimated net weight of 81 tonnes.

CIG was responsible for the engineering and production of the steel building package. Working from the approved 3D model, our team developed the production information, optimized the plate divisions, prepared the individual components for fabrication, and produced the workshop and assembly drawings required for the supplied sections.

Production included material procurement, cutting and marking of the individual components, weld-edge preparation, and cold forming of the three-dimensional steel plates. The bridge incorporated S355 structural steel in thicknesses ranging from 12 to 25 mm, with the curved plates formed to create the distinctive transitions throughout the structure. Reference lines and identification markings were applied directly to the components to support accurate prefabrication and assembly.

CIG also produced the formed tubes required for the handrails and processed the individual parts into a coordinated building package for delivery to the project team.
