"The two bridges are modeled as urban design objects and their shape is inspired by nature as a skeleton of an ancient animal. Inspiration comes also from the world of navigation, in fact the structure of the bridges reminds the structure of river boats.
The bridges were designed with Rhino and Grasshopper since the very beginning of the competition phase.
Rhinoceros and Grasshopper were used for many purposes:
First, the two bridges were generated by the same algorithm, which is good for time saving and especially good to check the design at the initial phase, in fact the bridges have the same shape but different measures. The one in Lombardini street is 20m long, whereas the one in Parenzo street is just 18m. Both are 5m wide at the center.
Then, the main curvature is controlled in Rhino and Grasshopper to have a correct slope for Italian regulation. Plates below the bridge are parametrically controlled in their shape and number.
We controlled the surface of the bridge up to the detailed scheme defining in Rhinoceros the thickness of all the different elements. The Balustrade is also modelled with Grasshopper, even if it has a simple typology its vertical elements are at different coordinates because they follow the main curvature of the bridge.
In conclusion, Rhinoceros and Grasshopper were very useful to achieve an astonishing design and at the same time a very good control of the overall geometry".
