It was the 5th tallest in the world when completed in 2016,[4] 44 m (144 ft) surpassed by Ping An Finance Center since March 28, 2017 (6 days before opened to the public).

"Sky Bridge Tour" is on the roof at 541 m,[5] same height with One World Trade Center.

History

After 13 years of planning and site preparation,[6] the tower gained final approval to start construction by the government in November 2010[6] and the first groundbreaking activities of piling and frame assembly were observed at the construction site in March.

On New Year Eve of 2016, the LED-pixels of the facade displayed the number "2016".[7]

On April 3, 2017, Lotte shot off fireworks to celebrate the tower's official opening.[8]

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.

Design

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 metres (39 ft) and weigh 20 tons. The counterparts were made up of bent metal panels that are 6 cm (2.4 in) thick. The roof structure itself is 120 metres (390 ft) high and covers floors 107–123. Approximately 3,000 tons of steel parts, a high-precision 64t tower crane and GPS alignment systems, as well as highly skilled 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).

The conceptual design calls for a slender cone with convex, gently curved sides. An exterior of pale-coloured glass draws inspiration from Korean ceramics and features accents of metal filigree.[9]

Incidents and accidents

Safety issues

In 2013 and 2014, three construction workers died during the construction of the tower, and an executive director of Lotte's construction arm was given a suspended sentence of eight months in prison in 2016 for his role in neglecting safety measures at the site.[13] In December 2014, the Seoul city government ordered the mall and cinema complex at the base of the tower, which opened before completion of the tower, to be closed for five months after water was found leaking from an internal aquarium. Independent engineers who assessed the building found that these issues bore little relation to the overall structural integrity of the building and the mall and cinema complex reopened in 2015.[14]

Urban exploration

In 2016, two Russian and Ukrainian urban explorers, Vadim Makhorov and Vitaly Raskalov from Ontheroofs, illegally climbed the under-construction Lotte World Tower through stairs and Vitaly Raskalov then free-climbed up the crane on the tower's top.[15][16] The video was viewed over 4 million times as of March 2023 and received worldwide media attention.[17][18] Following the climb, Lotte World Tower released posters with the photos of Vitaly Raskalov and Vadim Makhorov and banned them from the building.[19][20]
