"Porta del Sud" Railway Station, Italy

Designed by Zaha Hadid, the new station – a construction consisting of concrete, glass and steel in the form of a bridge – is characterized by numerous curved shapes. Traffic flows from travelers inspired the architect to create this extraordinary shape.
For the design of the very special “Porta del Sud” architecture, PERI´s Italian engineers developed a cost-effective overall solution for all formwork and scaffolding work. In addition to standard formwork systems, a large number of customized formwork elements were planned, produced and delivered.
The project in numbers: 19,000 m² of reinforced concrete slabs and 26,500 m² of wall areas – of which 16,500 m² in the best possible architectural concrete quality.
For the curved and inclined walls, elements of the VARIO GT 24 Wall Formwork were accurately planned, prefabricated and delivered to the construction site. The Girder Wall Formwork could be optimally adapted to suit the complex geometries and the high architectural concrete requirements including the required joint and tie arrangement.
The VARIO GT 24 Girder Wall Formwork was planned and assembled according to project demands – with reinforcing steel walers and up to 12 m in height.
The MULTIPROP Props are characterized by a high load-bearing capacity of up to 90 kN. For forming the platform, aluminium props were used under the slab tables both as individual props and as shoring towers.
The VARIO GT 24 Wall Formwork and PERI UP Modular Scaffolding demonstrated adaptability par excellence – also for the very challenging architectural concrete components.
Designed by the British-Iraqi architect Zaha Hadid, the station was conceived as a bridge that floats 30 m above the railroad tracks and links them together. The futuristic station thus acts as a gateway to the city of Naples.

The construction of the station in Afragola, designed by Zaha Hadid, was not a simple undertaking – we had to bring the future-oriented architectural concept together with the working material used: concrete. One can say that this was successfully mastered thanks to the excellent collaboration between Astaldi and PERI!
