    The Doka formwork solution fielded here uses SKE100 and SKE50 plus automat-ic climbers and the Protection screen Xclimb 60, and is ensuring swift, safe construction progress. In a formwork-engineering first, the Formwork Experts are using telescoping protection screens and platforms to deal with the structures continuous taper.

    The Lotte World Tower is a project on a superlative scale. Once this skyscraper is completed, its 123 storeys will house not only shops, offices and small apart-ments (known locally as officetels), but also a 7-star luxury hotel. The top ten storeys, with a viewing platform and caf on the rooftop terrace, will be giv-en over to public use. According to this megabuildings architects Kohn Peder-sen Fox, the visual design of the gently tapered tower, with its uninterrupted cur-vature, was inspired by elements of tra-ditional Korean ceramics, porcelain and calligraphy. The client, the Lotte Group, is incorporating photovoltaic panels, wind turbines, exterior shading devices and rainwater harvesting systems into the building. Elegance of form was one of the prime objectives. The facade will be clad in light-toned silver glass accent-ed by a filigree of white lacquered metal.

    Keeping time with automatic climbersFor the formwork of the immense rein-forced concrete core, which has now (early November 2012) reached a height of 140 m, Doka is again deploying know-how that has seen many such meg-aprojects through to a successful con-clusion: 132 SKE100 automatic climb-ers, 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.

    twelve SKE100 automatic climbers are being used to raise the three concrete placing booms in sync with the form-ing cycles. Eighty SKE50 plus automatic climbers carrying Large-area formwork Top 50 are being used to construct eight 318 m tall, solid-cross-section mega-columns on the outside of the structure, to give it extra stability and safety. Work has been progressing very satisfactorily, says Doka Project Manager Klaus Eck-stein: Despite the tight timeframe, we finished all the planning work in good time. The formwork deliveries all went to plan and work on the site is moving ahead well.

    Telescoping protection screenAt present, the work platforms are enclosed with netting and tarpaulins. A 20 m high Protection screen Xclimb 60 will soon be providing a gapless enclo-sure around the top four and a half sto-reys at any one time, probably from the beginning of 2013.
