The Lotte World Tower, a building made of steel, glass and concrete 123 floors from the ground floor up, comprises a total area of around 502,450 sq m, to be used for hotel rooms and offices. The American architecture firm Kohn Pedersen Fox, which has also already realised several skyscrapers in Asia and North America, created the exceptional design of this building and is responsible for further planning. The skyscraper has a square floor plan, narrows towards the top and is rounded at the corners. A steel structure with glass panels will stretch 555 m into the sky.

Stationary concrete pumps from Putzmeister will deliver approximately 86,415 cu m of concrete by completion date. The compressive strength class of the concrete to be machined is between C 60 and C 90 and will decrease towards the top. The specialists at Putzmeister have gathered sufficient experience in such projects, for example, during the construction of, to date, the world's tallest building, the 828-m high Burj Khalifa in Dubai.

Equipment being used
Two concrete pumps, type BSA14000SHP-D (570 kW), and three concrete placing booms, type MX 32-4, on Putzmeister's own tubular column system (RS 850) for concreting ceilings.
