Construction of Lotte Super Tower to begin Saturday
JUNE 02, 2011 05:08
Construction of the second Lotte World complex, or Lotte Super Tower, will begin Saturday with an aim of completion by late 2015, the builder of one of the world’s tallest skyscrapers said Wednesday.
Lotte Corp. CEO Lee Won-woo told reporters at Lotte Hotel in Seoul that concrete consolidation work for the skyscraper will begin Saturday and continue through Sunday.
A huge amount of concrete enough to build 450 apartment units each covering 132 square meters will be poured into the site for 32 hours.
More than 5,300 concrete mixer trucks will be mobilized to deliver the cement. If the trucks are put in a line from the construction site in Seoul`s Jamsil district, they would reach Osan, Gyeonggi Province.
In addition, 4,000 tons of iron bars each 51 meters in diameter and 50 percent thicker than ordinary ones will be used. The massive volume of building materials is necessary to bear the weight of the 740,000-ton skyscraper.
The size of the concrete foundation is also enormous, reaching 80 percent of a soccer field. It measures 72 meters in both width and length and its height is equivalent to that of a two-story building.
The builder said, “Its scale is the world’s fourth largest after China’s Shanghai Tower, Hongkong’s ICC and China’s Shanghai World Financial Center.”
Lotte Corp. will also utilize cutting-edge homegrown construction technologies and methods, including wind and earthquake resistant designs, a technique to build one story every three days, and a high-strength concrete pumping technology that can shoot concrete up 500 meters above ground.
Ground construction for the skyscraper will begin next year after underground construction is completed by year’s end.
