Lotte World Tower (Korean: 롯데월드타워) is a 123-floor, 554.5-metre (1,819 ft) supertall skyscraper that finished external construction on March 17, 2016. The building's final 123rd floor was topped out on December 22, 2015. It is currently the tallest building in the OECD, and is the 5th tallest building in the world.

History

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 2011.

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

On March 27, 2016, the first break in and climbing incident occurred. When the tower was still under construction, two Russian photographers Vitaly Raskalov and Vadim Makhorov climbed to the top of the crane and took pictures and a video. They entered the construction site without permission. Due to public's awareness of potential North Korean agent attack, security was notified about this intrusion. News reports lashed the enterprise's public image as well.

Height

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.

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. 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.

Urban exploration

In 2016, two Russian and Ukrainian urban explorers, Vadim Makhorov and Vitaly Raskalov from Ontheroofs, climbed the under-construction Lotte World Tower through stairs and Vitaly Raskalov then free-climbed up the crane on the tower's top. The video was viewed over 2 million times as of September 2016 and received worldwide media attention. Following the climb, Lotte World Tower released posters with the photos of Vitaly Raskalov and Vadim Makhorov and banned them from the building.
