*외골격 스트럭쳐 시스템 타워, 버블버블 [ Reiser + Umemoto ] O-14

반응형


디자인은 단순히 심미적 만족을 위한 행위가 아닙니다.

두바이 워터프론트에 위치한 오14타워는 독특한 외형만큼이나 경제적으로 유리한

건축공간을 구현합니다.

일반적인 오피스 건물은 구조를 지지하기 위한 내부 코어와 기둥 그리고

이러한 공간을 보호하기 위한 외피시스템으로 결정됩니다. 하지만 오14타워는

건축물을 감싸고 있는 외피시스템을 통하여 구조와 스킨을 통합함으로써

내부 공간의 자유로움과 다양성을 제공함은 물론 타워의 외형적 아이텐티를 구축하여

워터프론트에 랜드마트로 제안됩니다. 또한 콘크리트 셀구조의 다양한 오프닝은 내부 프로그램과

호흡하며 내외부의 간극을 좁히는 창으로 건축물의 한계를 뛰어 넘습니다.

교보생명 사거리에 위치한 어반하이브 빌딩과 묘한 대비를 이루네요.

O-14, a 22-story tall commercial tower perched on a two-story podium, broke ground in February 2007, and comprises over 300,000 square feet of office space for the DubaiBusinessBay.  O-14 is located along the extension of Dubai Creek, occupying a prominent location on the waterfront esplanade.  With O-14, the office tower typology has been turned inside out – structure and skin have flipped to offer a new economy of tectonics and of space.




Architects: Reiser + Umemoto
Location: ,
Project Year: 2010
Photographs: Nelson Garrido

Project Area: 31,400 sqm
Structure: Perforated Concrete Exoskeleton


The concrete shell of O-14 provides an efficient structural exoskeleton that frees the core from the burden of lateral forces and creates highly efficient, column-free open spaces in the building’s interior. The exoskeleton of O-14 becomes the primary vertical and lateral structure for the building, allowing the column-free office slabs to span between it and the minimal core.  By moving the lateral bracing for the building to the perimeter, the core, which is traditionally enlarged to receive lateral loading in most curtain wall office towers, can be minimized for only vertical loading, utilities, and transportation.  Additionally, the typical curtain-wall tower configuration results in floor plates that must be thickened to carry lateral loads to the core, yet in O-14 these can be minimized to only respond to span and vibration.  Consequently, the future tenants can arrange the flexible floor space according to their individual needs.


The main shell is organized as a diagrid, the efficiency of which is wed to a system of continuous variation of openings, always maintaining a minimum structural member, adding material locally where necessary and taking away where possible.  This efficiency and modulation enables the shell to create a wide range of atmospheric and visual effects in the structure without changing the basic structural form, allowing for systematic analysis and construction.  As a result, the pattern design is a combination of a capillary branching field, gradients of vertical articulation, opacity, environmental effects, a structural field, and a turbulence field.


The project has generated extraordinary international interest in the architectural press as it is among the very first innovative designs to be constructed among a sea of generic office towers which have come to be the standard in Dubai’s current building boom.  O-14 was recently featured in ‘ImpossibleCity’, an hour-long television documentary about the recent growth in Dubai, which was produced by CBS News and aired in the U.S. on the Discovery Channel in October, 2008.  In May 2009, the tower’s concrete structure was completed and the building was topped out, making O-14 one of the first towers to appear in the skyline of Business Bay, Dubai.  It was completed in January of 2011.
