Lotte World Tower
Lotte World Tower (Korean: 롯데월드타워; RR: lotdewoldeutawo) is a 123-story, 555 metres (1,821 ft) supertall skyscraper, located in Sincheon-dong, Songpa District, Seoul, South Korea. It is the sixth-tallest building in the world, the tallest in OECD countries and in South Korea, and also the first in South Korea to be over 100 stories tall. It was the fifth-tallest in the world when completed. The tower opened to the public on April 3, 2017.
A "Sky Bridge Tour" is located on the roof of Lotte World Tower at 541 m (1,775 ft), which is about the same height of One World Trade Center in New York City (1,776 feet or 541 meters), the tallest building in the United States.
After 13 years of planning and site preparation, the tower gained final approval to start construction by the government in November 2010 and the first groundbreaking activities of piling and frame assembly were observed at the construction site in March 2012.
On December 31, 2015, the LED-pixels of the façade displayed the number "2016".
On April 3, 2017, Lotte shot off fireworks to celebrate the tower's official opening.
On January 1, 2018, Lotte shot off fireworks with a LED laser show for seven minutes to celebrate New Year's Day and the 2018 PyeongChang Winter Olympics.
On March 17, 2016, before the final phase of external construction, the diagrid lantern-shaped roof structure was completed. The roof structure was constructed with steel counterparts that are each 12 m (39 ft) and weigh 20 tonnes (20 long tons; 22 short tons). The counterparts were made up of bent metal panels that are 6 centimetres (2.4 in) thick. The roof structure itself is 120 m (390 ft) high and covers floors 107–123. Approximately 3,000 tonnes (3,000 long tons; 3,300 short tons) of steel parts, a high-precision 64-tonne (63-long-ton; 71-short-ton) tower crane, and GPS alignment systems, as well as welding technicians, were used in the construction of the roof.
The roof structure is engineered to withstand its weight without reinforcing pillars, endure earthquakes up to a magnitude of 9 under the Richter magnitude scale, and winds up to 80 m/s (260 ft/s).
