Safe climbing combinations without a crane
The 180 m high conveniently located highrise building has 46 floors with over 55,000 m² of office space. The 22 m x 20 m reinforced concrete core was climbed with ACS: five ACS P working platforms for the elevator shafts and stairway as well as eight ACS R climbing platforms on the core outre sides.
Both versions of the modular ACS system were combined with VARIO GT 24 girder wall formwork and formed large-sized moving units. These were climbed hydraulically, i.e. crane-independent and regardless of weather conditions, to the next section in each case. With smaller shaft dimensions, the BR shaft platforms were used.
Five floors below, the three uppermost floors at any given time were completely enclosed with the RCS climbing protection panel. In addition to providing safety against falling at the slab edges, the enclosure also created a sheltered working area which clearly increased productivity at great heights. Similar to the ACS self-climbing technology, the RCS rail climbing system was connected to the building during the entire climbing procedure by means of climbing shoes. The construction crew also decided to use the RCS crane-independently: with the help of mobile self-climbing devices.

“Our decision in favour of ACS was absolutely right. The system is safe, quick and reliable. It is easy to operate and saves time as well as crane capacity. As a result, we could achieve a 4-day cycle and clearly accelerate our construction schedule. ”
