The design reflects the vision of KT as a landmark tower and the generous spirit of the KT employees, Customers, and Visitors who serve this place. From the exterior, the form clearly emphasizes symbolism of KT by introducing elements for art, culture, nature, environment, and technology. The recognition of the towers and it’s facade creates a unique transition between the US Embassy and Kyobo with a dynamic gesture of multiple towers. The spatial flow expands public open space and connection from Gwanghwamoon plaza to Joonghak stream and provides an organic & 3 dimensional linkage from Gwanghwamoon plaza to Cheongjin tower through KT plaza, atrium, and deck. Eventually, the towers will be a center, in which will heighten the spiritual spot of KT technology, and provide awareness of the history & culture of Sejong-Ro to public.

Structural Model of Tower A

Complex geometry

Towers feature the Architect’s signature complex geometry consisting of sloping, faceted, and sheared envelopes. The key to the most efficient structural system for this type of the building is how to minimize additional bending and twisting moment due to the geometry, and how to minimize column transfers and maximize the efficiency of the parking underground.

Gravity system 

Floor framing will be a typical 135mm truss deck over the steel H-shape beams. An example framing plan is provided below. Columns will be a concrete section with steel shape embedded. Steel shape ratio is assumed as 10%. Preliminary maximum column size at the 1st floor is 700x700mm. To maximize column-free internal area, 13~15m internal span is proposed for certain locations. Detailed floor vibration analysis to ensure serviceability will be carried out in the schematic design phase.
