For the formwork of the immense reinforced concrete core, Doka is again deploying know-how that has seen many such megaprojects through to a successful conclusion: 132 SKE100 automatic climbers, combined with Large-area formwork Top 50, are being climbed ahead of the floor-slabs, in casting sections that are 4.5 m high in the typical storeys. Automatic climbing formwork SKE50 plus is being used to construct eight 318 m tall, solid-cross-section mega-columns on the outside of the structure.
Telescoping protection screen
Since June 2014 a 20 m high Protection screen Xclimb 60 is providing a gapless enclosure around the top four and a half storeys at any one time. All operations are carried out sheltered from climatic influences and high winds. The constantly changing shape of the structure presented the Formwork Experts with a great challenge in the planning phase. The Doka project team’s answer was to develop a new, telescoping protection screen specially for the Lotte World Tower; this screen takes little or no modification to adapt to tapering structure shapes. The screen elements can be adjusted to widths of between 3 m and 5 m. Says Doka Project Manager Klaus Eckstein: “One of the exciting things about this assignment was that there were more than 20 of us in a single team based in three different countries – Korea, Singapore and Austria – all working together to devise and implement individualised solutions for the Lotte World Tower.”
