Designed to be the tallest building in Asia, Lotte Super Tower’s core-and-shell structural system was engineered to achieve a superlative height. A cast-in-place concrete core works with a steel diagrid shell that is expressed in a unitized curtain wall. An enclosure system was designed to integrate the complex diagrid geometry with a relatively conventional curtain wall.

The shape of the tower, as it rises from a 70-meter square base to a 40-meter diameter circle at its top presents an extremely efficient structure. While the tapered form creates better mass distribution overall, the aerodynamic profile and smaller surface area at the top of the building avoid wind loads where they are greatest. Additionally, at the base and top of the tower, the curtain wall uses a custom-engineered, unitized cable-net system, which has never before been built and will be the highest-elevated cable-net structure in the world when complete.
