here are a few more photos of the bridge on site, provided by Manuela Gatto.
bridge deck was created by a series of "diaphrams" or ribs with steel paneling underside, bent and welded at the central support "belly" to form double curvature. 2 spinal arches "top chords" transfer loads to the pilecaps at both ends and centre of the bridge. connecting the deck to the "top chords" is the faceted diagrid which also acts as the secondary facade structure.
it was a great project to work on, rationalizing the geometry from the competition stage to construction documents, achieving repetition in the facade panelization while using planar structural elements to reduce cost.
all modeling was done in Rhino 3. Shop drawings were generated from a Catia 3d model.
