ACS and SKYTABLE minimise crane times
In each case, two asymmetrically curved legs were positioned against each other which grow together like bridge pylons and formed three concave-shaped hotel towers. The individual building elements differ from each other in terms of the base width, curvature radius and lateral offset dimensions whilst the individual floors are also offset from one another in a longitudinal direction. Only two cranes per tower were available to the construction crews, therefore craneindependent and crane-saving formwork solutions were used to construct the core walls and floor slabs respectively. With the help of ACS self-climbing technology and the large-area SKYTABLE slab tables, crews were able to finish a complete floor with a standard height of 3 m in only four days. Twelve elevator shafts were climbed three cycles in advance and a total of 110 SKYTABLE slab tables were required for constructing two complete floors in each case.
Up to 20 m long and 5 m wide, the 100 m² SKYTABLE units could be easily moved with only one crane lift. The innovative moving method ensured that the table was always pulled out of the building in a horizontal position and the operating personnel were always standing in a safe and secure place on the slab edge. Due to the large lowering height of the MULTIPROP props, 20 cm slab offsets and, at the same time, 50 cm parapet wall heights presented no problems. Connected to MRK frames, the tables could be additionally used for the 9 m high intermediate floors.
With the help of ACS, the different-sized shafts with dimensions ranging between 2.30 and 10.10 m, colud be shuttered, struck and climbed without the need of a crane. Altogether, five working levels climbed at the same time to the next section: two platforms for forming, reinforcement work and concreting the shaft walls as well as three finishing platforms for pretensioning the subsequent storey slabs. In combination with CB climbing scaffold and the VARIO GT 24 girder wall formwork, operational sequences on the construction site were thus optimised.

Project Manager
“We are extremely satisfied with the PERI systems and the comprehensive service which provide us with competent engineering, logistics and site support for ensuring a successful completion of the project. With SKYTABLE and ACS, we can work safely and with minimum use of the crane - as a result, we need less than 4 days for one floor.”
