Generali Tower, Italy

Lo Storto, The Twisted One, the future administrative building of the Generali Insurance Group
The 170 m high office tower bears – as does the residential development section of the Milan CityLife project – the handwriting of the recently deceased star architect, Zaha Hadid.
The complete enclosure using the RCS Climbing Protection Panel reliably secured the top floors under construction each time.
MP Landing Platforms: Part of the PERI climbing concept was the utilization of MP Landing Platforms for moving and intermediate storage of formwork materials. The cantilevered RCS Rails were simply clamped by means of MULTIPROP props between two floor slabs.
The PERI climbing formwork solution for the high-rise core was based largely on the crane-independent working RCS Rail Climbing System, combined with a self-climbing ACS Platform Unit as well as crane-climbed CB Climbing Platforms and BR Shaft Platforms.
With protection provided by the RCS enclosure, fast and safe forming operations could be carried out with SKYDECK Panel Slab Formwork and special formwork elements based on SRS Circular Column Formwork.
In addition to ensuring short striking times, the SKYDECK Panel Slab Formwork also allowed easy adaptation to match the slab geometry which changed from storey to storey.

Our aim is to always find the right balance between technology and economy. Together with the PERI engineers, we developed the best way to realize the tower at the right price. Ultimately, we were able to complete the required building work in advance of the contractual construction period – to the great satisfaction of our client.
