Lotte World Tower (Korean: 롯데월드 타워) is a 123-floor, 555-metre (1,821 ft) supertall skyscraper and has finished external construction on March 17, 2016. The building's final 123rd floor was topped out on 22 December 2015.[3] It is currently the tallest building in the OECD.

The tower is located next to the existing first-generation Lotte World complex, which opened in 1989, accessible via Seoul Subway Line 2 and Seoul Subway Line 8 at Jamsil Station.

History

After 13 years of planning and site preparation,[4] the tower gained final approval to start construction by the government in November 2010[4] and the first groundbreaking activities of piling and frame assembly was observed at the construction site in March 2011.

At New Year 2016 the LED-pixels of the facade showed "2016".[5]

On 27 March 2016, the first break in and climbing incident occurred. When the tower was still under construction, two photographers Vitaly Raskalov and Vadim Makhorov climbed to the top of the building and took pictures and a video.[6] They entered the construction site without permission. Due to people's awareness of potential North Korean attack, security was notified about this intrusion.[7]

Roof

On March 17, 2016, prior to 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 meters high 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 64t 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.[8]

Floor plans

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] Located near the Han River, the tower will contain retail outlets (floors 1-12), offices (14-38), residences (42-71), a luxury hotel (76-101), private office (105-114), and public access floors (117-123) with an observation deck.
