On 8th November 2007, the Burj Dubai broke the 600 metre mark and is already the tallest building on the planet.
Doka, the formwork specialists, were on site for this event and never before in the history of formwork technology has climbing formwork been deployed over such a long period, at such a great height and under such extreme conditions.
Successful completion of the in-situ concreting works on the structure core has brought Doka not only a world record but also some valuable experience of extreme situations. The architectural design, too, made some exceptionally tough demands of the formwork system. The Y-shaped, wing-walled structure core of the Burj Dubai tapers upwards, undergoing no fewer than 32 changes in layout as it does so. As early as when planning its “forming machine”, Doka had to make allowance for each of these adaptations, right down to the last detail. Separation points in the platform system enabled the formwork solution to be modified safely and reliably every time the layout changed, with only minimal impact upon the cycle time. In order for the storeys to be poured in a 3-day cycle, the system also had to be highly efficient and easy to operate.
There is still no word on the final height but rumours are somewhere between 700 - 850 metres. To put that into perspective that is twice as tall as the Petronas Towers or the Sears Tower.

Dubai seems to be a concrete jungle in the middle of a sand desert... But seriously, I think this UAE city is the shape of things to come as far as construction, and the looks of future cities is concerned.
