Lotte
World Tower is a 123 floor 555.7 metre
(1,823 ft.) skyscraper located in Seoul, South Korea.
It opened to the public on April 11, 2017, and is currently the tallest
building in South Korea and the fifth tallest in the world.
The roof structure was constructed with steel
counterparts that are each 12 meters and weigh 20 tons. The counterparts were
made up of bent metal panels that are 6 cm thick, and the structure itself
is 120 meters high, and it covers floors 107–123. Approximately 3,000 tons of
steel parts, a high-precision 64th tower crane, high-precision GPS alignment
systems and highly skilled welding technicians were used in the construction of
the roof itself. The roof structure is engineered to withstand its weight
without reinforcing pillars, and endure earthquakes up to a magnitude of 9
under the Richter magnitude scale and winds up to 80 m/s.
