The owner has allowed engineers to use the structure for research comparing long term elasticity, creep, and shrinkage of the concrete walls versus the concrete columns. So far the comparison between projected and actual behavior has been favorable.

The tower's aerodynamic design was so efficient that its stability in high wind exceeds international standards and no additional damping devices were needed.
Tower G is South Korea's tallest building.
This was the world's tallest all-residential tower in the world for a brief period during its construction, surpassing the previous record-holder Trump World Tower in New York City. 21st Century Tower in Dubai was topped out later but finished sooner, claiming the new record by 5 meters.
The foundation mat was built using innovative self-compacting self-consolidating concrete. This reduced casting time from 48 to 12 hours.
The structural system is a megaframe consisting of a concrete core bound to concrete perimeter columns through an exterior belt wall.
The building's shape is formed by three oval lobes joined together, and was designed aerodynamically to tame the effects of wind pressure and building sway.
