Bridge across the river Wall at Nijmegen (Netherlands)
| purpose: | road bridge |
| load-bearing structure: | steel beam stiffened with an arch; lower box section bridge deck |
| span: | 285 m |
| weight: | 6 040 t |
| investor: | the City of Nijmegen |
| commissioning: | 2013 |
Complex basic geometry and camber created many surfaces, which could not be simply developed. The developed sheets had to be processed using a special function for developing doubly curved bodies (software Siemens NX).
Bridge across the Sundsvall Bay (Sweden)
| purpose: | road bridge |
| load-bearing structure: | continuous steel beam with box section |
| length of the bridge: | 1 420 m |
| max. length of one span: | 170 m |
| weight: | 23 000 t |
| investor: | Trafikverket |

A complex layout of individual lanes near supports, variable width of the bridge, and division of the box by longitudinal girders created a relatively sophisticated arrangement of steel trough ribs on the bridge deck.
Our firm participated in making the assembly design and also designed assembly aids.
