World Port Centre, Rotterdam, Netherlands
Five days per floor
With ACS self-climbing techniques
At the end of the Rotterdam Wilhelmina Pier, at Kop van Zuid, immediately next to the Hotel New York, lies the new building of the World Port Centre. The 125 m high office building was erected to the plans of the well-known architect, Sir Norman Foster.
The stabilizing element of the 32 floor building construction is a two-piece core for lifts and stairwells. From the 6th to the 23rd floor the core has four wing walls, that were to be considered in the formwork design, just as a circular wall of 5.00 m radius.
After constructing the basement walls conventionally with VARIO girder wall formwork, the ACS self-climbing system followed from the third concrete pour. Altogether 25 ACS units were used (21 ACS-R, 3 ACS-P, 1 ACS-G).
For the best possible adaptation to the construction sequence the two cores could be climbed simultaneously or independently of each other.

The formwork height was 3.60 m because the maximum concrete lift was specified as 3.50 m, resulting in a formwork area of 1,180 m² for both cores.

Although the contractor worked with ACS for the first time, the normal floors were able to be completed in only five working days per floor. |
