Porta Nuova Garibaldi, Milan, Italy
PERI self-climbing technology comprehensively combined
With the Città della Moda, architect César Pelli has given a new, modern face to the city of fashion Milan. The “Porta Nuova Garibaldi” complex- comprised of several tower blocks arranged in a circle around a three-storey centre with 100 m diameters - towers above everything. Then with a height of 220 m, Tower A is the highest building in Italy. It has a total of 32 floors whilst Tower B follows with 23 storeys and is 102 m high. Each of the two towers has one central and two laterally positioned reinforced concrete cores. PERI accepted the challenge and, with the help of detailed planning and modern formwork systems, a complete standard floor could be realised per week. In addition, a high level of safety accelerated construction progress of the two dominating towers.
For an optimal work flow, two ACS selfclimbing variants were combined which, with a total of 101 ACS climbing devices and 19 hydraulic pumps, ensured craneindependent shuttering, striking and climbing operations. In addition, two placing boom masts could be integrated and carried along at the same time. Over 2,500 m² of formwork was used to form the very often rounded-shaped walls. Furthermore preassembled VARIO GT 24 formwork elements were delivered having been manufactured for a precise fit in the PERI assembly hall beforehand. A further 2,500 m² of slab formwork also guaranteed fast forming times for the floors: the SKYDECK panel slab formwork, with the systematic assembly sequence and drophead system for early striking, could follow the tight concreting cycle schedule for the cores.
The RCS modular system completed the PERI overall solution and significantly accelerated the construction work. The RCS climbing protection panel provided the railclimbing system with a safe, 250 m long completely closed enclosure for the rounded floors under construction. In order to be able to also work crane-independently for the vertical transport of the SKYDECK formwork elements, two RCS formwork lifts were integrated into the protection panel solution. For both applications, the committed construction site team used mobile RCS self-climbing devices in order not only to allow rail-guided climbing but also craneindependently.
