21st Century Tower is a 55-story skyscraper along the Sheikh Zayed Road in
Dubai . At a height of 269 m (883 ft) it is the world's third-tallest
residential building.
It was the world's tallest residential building when it was
completed in 2003, but later the Eureka Tower in Melbourne, Australia
and the Q1 tower in Australia's Gold Coast bumped it to its current
position.
It is occupied by Cabin Crew members of Emirates Airline, and
boasts a gym on the top floor and a pool on the roof.
State of the art building maintenance systems keep its occupants
secure and comfortable despite the extreme climate of the U.A.E.
The skyscraper contains 6 elevators. During requests for an
elevator, an intelligent elevator system automatically directs the
closest elevator to the requested floor. Equally interesting is the fact
that no balconies exist on any of the floors, including the lower
levels.
Combining state of the art technology with creative design, each
floor of the Tower is zestfully designed and decorated. Remaining
faithful to the fact that the beauty of sky-scraper living is in the
view, each bedroom is provided with large windows either overlooking the
Persian Gulf or the futuristic Sheik Zayed Road.

21st Century Tower, Dubai, United Arab Emirates
Core, Slabs and Facade in a 3-Day Cycle
269 m High Apartment Block
The 21st Century Tower with its 53 storeys, approx. 400
apartments and a total height of 269 m, is another constructional
highlight along the Sheikh Zayed Road in Dubai.
PERI Dubai was commissioned to provide a formwork solution which
enabled the contractors to fulfill the high requirements and also the
tight construction schedule.
Using experience from various successful projects in the past,
such as the National Bank of Dubai headquarters and the Emirate Tower,
PERI engineers developed a clearly defined concept for this ambitious
project.
Using ACS self-climbing technology, the VARIO girder wall
formwork for the rectangular core climbed crane-independently from
storey to storey. CB 240 climbing brackets and VARIO were used for the
facades. The facade formwork could be retracted on the brackets for
striking and then moved as a unit to the next storey by crane which
saved a lot of time. MULTIFLEX slab formwork on PD 8 shoring towers for
the slabs of the service and maintenance floor completed the PERI
formwork programme used in this successful project.
Thus, the contractors could achieve the planned 3-day cycle for
one complete 1,350 m² floor.

“PERI ACS is unbelievably fast and extremely safe. Due to the
self-climbing technology, we could save on considerable amounts of crane
capacity which is a big advantage on construction sites like this one.”
