INDEX TOWER, DUBAI, UAE

Index Tower is a prestigious 86-storey structure designed by architects Norman Foster + Partners, developed by Union Properties, and located in the heart of the Dubai International Financial Centre. 

The design features four tapering A-frame fins at 27 metre centres, which are buttressed at east and west elevations in the top section.

The structure had to incorporate a large open area at the ground level while supporting 86 storeys. In order to accommodate this, CCL designed six-metre-deep transfer beams using a CCL 37 strand system. Very careful attention to detail was required when carrying out the design and execution of this critical structural element.

CCL multistrand systems were also used in the bracing beams around the perimeter of the structure. More than 118,000 m2 of CCL post-tensioned slabs were completed on the project, and a casting sequence of four days was achieved to meet the strict deadlines.

The then CEO of Union Properties, Simon Azzam said ‘This will be one of the first of a new era of ‘intelligent buildings’ destined to be the skyscrapers of the future.’
