Turkey
Skyland Office Tower,
Istanbul
At 284 m height each, the
Skyland Office Tower and
Residence Tower will be
Turkey’s tallest buildings
upon completion.
Construction of the Skyland
Office Tower in progress in
the heart of Istanbul building
will be Turkey’s tallest structure.
Doka’s Platform SCP is a feature of the
construction.
This high-rise-core forming machine
ensures rapid construction progress.
Doka is also providing Xclimb 60
protection screen for both the Skyland
Office and Residence Towers.
Developer, Eroğlu, selected the
name “Skyland” for his three skyscrapers:
at 284 m height each, the Skyland
Office and Residence Towers and the
Skyland Hotel. The main building contractor
is Alcen.
Challenging Formwork Demand
The challenge presented by the office tower in terms of
formwork technology is twofold:
• The architects decided on a triangular ground plan and,
therefore, the building core.
• The risk of earthquakes in Istanbul presents special
challenges related to static engineering.
Thus, lower level walls are 1.5 m thick, at 100 m they
measure 1.1 m, with the wall thickness reduced to 60 cm
in the final storeys. Additional stability is created thanks to
monolithic construction, where walls and floors are reinforced
in one go.
Given these demands, Doka’s self-climbing Platform
SCP was proposed. Alcen Owner, Alparslan Sabanci, said:
“We got introduced to this system during the
Ağaoğlu Maslak 1453 project; now we are using it
to erect the entire primary core of this skyscraper.
Doka submitted a better engineering solution”,
“The construction progress
shows that we made the
right decision when selecting
the Platform SCP.”
Optimised platform
for high-rise cores.
Any ground plan can be formed
quickly and flexibly with the new
version of this modular high-rise
core forming system. A few highperforming
hydraulic cylinders raise
the wall formwork – in this case
