The 429-meter-high Haikou Twin Towers is one of the most challenging construction projects in the world, or par with the building of Taipei 101 and the Petronas Twin Towers in Malaysia.
The development in Dayingshan Central Business District in China's southern Hainan Province has a total area of 720,000 square meters. The 428-meter-high south tower is expected to be completed in 2020, and the 429-meter north tower will be completed before the end of 2023.
The foundation for the building, the most difficult part of the construction process, was completed last year.
What makes this construction project so complex is the natural environment in which the building is located. The towers have to be both strong and flexible to survive strong earthquakes and typhoon force winds.
Ju Kaiyong, vice manager of the Haikou Twin Towers project, says that the skyscrapers will provide living and working space for more than 20,000 people and attract at least 3 million tourists each year. He adds the development will house a mix of restaurants, shops, offices, hotels and sightseeing spaces.
