The design for a modular, deployable, and adaptable bridge using parametric strategies and digital fabrication methods was developed by studio BÄNG. The design was conceived using the following rules:  Four data points were established at the beginning, middle, and the end of the bridge. These 12 parametrized points give the opportunity to steer the crosssection of the bridge at three important areas. Based on these points the defi nition creates three frames one for each end of the bridge and one in the middle.

All frames get connected and the resulting four-point polylines triangulated to get the base of the load bearing framework for each side of the bridge. The triangles get offsetted according to the sun and then moved in direction of their normals. By lofting the two resulting curves a rigid and complex looking shape occurs.

The most important benefit of parametric design and digital fabrication is the optimization of the whole design process. Modularity, the optimization of the construction time as well as saving material were the main goals. 

All angles in the construction are measured to give them to the electronic press brake. After getting the laser cutted and electronical press braked elements from the factory the only thing the construction workers have to do by hand is to close the 16 elements by screws. After closing the elements the modules are ready to be transported up to the site where the bridge shall be situated. Two workers are able to connect the parts with screws in less than 2 days.
