Floors formed quickly and reliably with ACS, RCS and SKYDECK
Construction of the two separate reinforced concrete cores took place in advance with ACS self-climbing technology and VARIO GT 24 girder wall formwork in regular weekly cycles. This meant shuttering, striking and climbing could be carried out without the use of a crane and in all weathers. For optimal working procedures, two versions of the modular ACS system operated next to ach other. The placing boom was also lifted ith the ACS from section to section.
The RCS climbing protection panel completely enclosed the slab edges of the trailing floors. Protected against strong winds, construction site personnel could work safely and productively in the top three storeys even at great heights. Mobile selfclimbing devices from the RCS modular system ensured crane-independent climbing with reduced and therefore cost-effective on-site material requirements.
In order to be able to maintain the planned weekly cycle, also when constructing the slab floors, the 850 m² area on each storey was formed using the SKYDECK system. The lightweight aluminium elements allowed simple, non-tiring and fast assembly. And with the drophead, early striking could take place. This meant that the main beams and panels were freed up to be used for the next cycle.
“The PERI systems we used contributed significantly to the fact that the concreting steps could not only be constructed quickly at great heights but also extremely safely.”
