One Za'abeel

Dubai, UAE

Al Abbar Group rose to the challenge of cladding the world’s longest cantilever  spanning over an existing highway.


As a symbol of ambition, innovation, and the pioneering spirit of Dubai, One Za’abeel will stand proudly at the heart of the city, strategically positioned within Dubai business districts. We are proud to be part of the construction of Dubai’s most innovative development in the Za’abeel district that pushes the limit of design and engineering.

One Za’abeel (a mixed-use development comprising of 2 towers 67 floors and 58 floors). Above ground, two towers are linked by a 120m high, 226m long  ‘Link Bridge’; the world’s longest cantilever structure.


Tower A:

The project utilises a unitised curtain wall system with slim frame on the inside and outer fritted glass fins (W=0.5m), connected to mullions with thermal break, as a structural and visual feature.

Double height frameless glass curtain wall ( H=7.5m ) are structurally bonded to inner glass fins at VIP areas Level 20/21 South Elevation.

The Link Bridge:

This element of the project makes use of architectural built-up steel structure (AESS 4) with a smooth surface, high-precision machining, polished and welding.  Fabrication and installation was conducted within allowable tolerances.

The façade units form a diamond shape with integrated inner blinds and LEDs at Link Bridge on both the north and south elevation.

The façade design included highly transparent, frameless glass units with 13m high glass fins at the East and West façade.

Soffit units with double glazing and inner metal cladding are installed above the active highway from a temporary platform. Laminated glass, unit frames and bracketry are structurally verified to take high wind loads up to 6kPa and maintenance loads from inside.

BMU tracks and LED units are integrated elements of the soffit façade.

An internal glass floor with triple laminated heat-strengthened glass supported by glass beams is provided at the Link Bridge West area.

Windscreen glazing and a free-standing glass box at top of the Link Bridge is provided,  125m above the ground and is designed to resist the high wind loads . The glass units are fabricated in low iron glass with a frit pattern. These are laminated with an SGP interlayer.
