Have any of you in Seoul ever visited Lotte World Tower? Historically, the 63 Building is more famous, but it is true that Lotte World Tower is attracting attention among the skyscrapers built in Korea recently, right?
However, I am curious how much you know about Lotte World Tower. Do you have the perception that Lotte World Tower is simply a skyscraper? Did you know that artificial satellites were used during the construction of Lotte World Tower? This time, I would like to introduce you to Korea's tallest building, Lotte World Tower. Through the construction of Lotte World Tower, we will also introduce Korea's excellent construction technology.

A brief introduction to Lotte World Tower
Lotte World Tower is a 123-floor, 555m high skyscraper in Seoul. It is the 5th tallest building in the world and is known to be the tallest building in Korea.
Lotte World Tower has various facilities such as shopping malls, hotels, offices, and residential spaces. In particular, there is an observatory called Seoul Sky from the 117th to the 123rd floor, where you can enjoy a 360-degree panoramic view of Seoul. Seoul Sky has the world's highest glass floor, Sky Cafe, and Sky Shop. There are many reports that Lotte World Tower is an eco-friendly building that saves renewable energy and water resources.

Design of Lotte World Tower
The design of Lotte World Tower was inspired by the traditional beauty of curves in Korea. The curve of the tower can remind you of the graceful beauty of traditional Korean materials such as Goryeo celadon (ceramics from the Goryeo period), hanbok, and eaves of hanok. In addition, the shapes of ceramics and brushes (a pen used by Koreans in the past) were expressed to encompass form and simplicity.
Lotte World Tower has a world-class wind and earthquake-resistant design. It has a wind-resistant design that can withstand typhoon Katrina-class (strong wind grade) winds of 80m per second and an earthquake-resistant design that can withstand earthquakes of magnitude 9 or higher.
In addition, as an eco-friendly building, Lotte World Tower has introduced renewable energy such as wind power generation, solar power generation, geothermal heating and cooling, and air conditioning using the Han River as a heat source.

Lotte World Tower and satellite technology
When constructing Lotte World Tower, artificial satellites were used.
Global Positioning System (GNSS) is a system that measures the 3D position of an object using artificial satellites. It is a technology applied to the Burj Khalifa in Dubai and the World Trade Center in New York. Lotte World Tower calculates the amount of correction considering the behavior of the building through measurement values simultaneously observed by at least 4 satellites and measurements of 7 inclinometers that can check how much the building tilts from side to side, and proceeds with ultra-precision construction without even the slightest error. I did.
These technologies go beyond verticality management to shorten the construction period and enable stable building maintenance through long-term continuous monitoring.
