The current condition of the site requires to stitch the two different areas, increasing the value of the railway crossing. After analysing different paths in relation to different urban densities, the initial aim was to study a network system, starting from the simplest connection among all the main points of interest along the railway direction. Through the experiments on soap films similar to Frei Otto’s ones, the optimized surfaces defined not only a shape but also many different intersection systems. In order to explore the 3d system, linear tractive and compressive efforts were applied on a membrane. In parallel, the same approach was studied digitally using Grasshopper plug-ins such as Kangaroo and Millipede. Back to the site, the anchor points of the structure were individuated in order to determine a 2D network among them. At the same time, the altimetric profile has been determined through the distance between the average of iso-curve positions and network boundary, multiplying with different coefficients. The structure provides different pedestrian crossing above the railway station and, inside the dynamical shaped structure, different zones find their own spatial identity and function.
