CFT pillars support the 300-meter-high building’s total weight of 285,000 tons. Concrete is forced inside high-strength steel frames to create the strongest pillars in the world. Concrete was compressed and moved from the first underground floor to a height of 300 meters virtually instantly with one of the world’s most powerful pumps.

Since Abeno Harukas is a skyscraper 300 meters above the ground, reference measurement positions could not be set up in the surrounding buildings. Therefore, the building’s accuracy was controlled by GPS measurements using a satellite.

Prior to the construction of the building, the slide cover construction method was developed to allow construction in a safe environment even 300 meters above the ground by sliding curing frames upward and preventing objects from falling from the higher floors. With this method, multiple construction projects can be carried out simultaneously and safely, such as erection of the steel frame on the top floor, the concrete placement below it, and the installation of the exterior aluminum curtain walls using a hoist crane below the slide cover on the lower floor.
