Building work

Formwork from Doka is playing a key role in constructing the airport’s buildings. At times as many as 80 cranes will be in use. Two-thirds of the formwork for the first construction phase are supplied by Austrian experts for formwork solutions, Doka. On this build the Doka engineers are combining in particular Timber formwork beams H20 eco and H20 top and load-bearing towers, plus Framed formwork Framax Xlife and Frami Xlife and Large-area formwork Top 50.

Doka formwork is helping to construct the buildings at the airport
Formwork from 203 Doka is playing a key role in constructing the airport’s buildings. At times as many as 80 cranes will be in use. Two-thirds of the formwork for the first construction phase are supplied by Austrian experts for formwork solutions, Doka. On this build the Doka engineers are combining in particular Timber formwork beams H20 eco and H20 top and load-bearing towers, plus Framed formwork Framax Xlife and Frami Xlife and Large-area formwork Top 50. The formwork systems from Doka are in use in many areas, including the runways, terminals, multilevel car parking facilities and hotels, and the wastewater treatment plant.


The load-bearing tower frames are steel, eminently suitable for high clearances and high loads. On the Istanbul airport build, these circumstances apply for the big downstand beams, which are 12m above ground level and on which the precast slab is laid. Because they are so strong and because of the wide frame span, moreover, the load-bearing towers are very safe. They also help speed up progress overall on the build, because vertical stacking is easy and assembly is a no-tools operation.

In all, 30,000 load-bearing tower frames and 100,000 running metres of Timber formwork beams H20 eco and H20 top are in use on this project. Large as the numbers are, they represent the optimised formwork solution on a construction project of this magnitude. Because the Doka load-bearing towers are designed for materials-saving use: the frames are oversized, so, all in all, fewer frames are needed to prop the structure.

    Formwork specialist Doka recently rose to the challenge on Turkey’s Eyiste Viadust, the country’s highest bridge with piers up to 155m tall. The Eyiste Viaduct will be part of a route between Central Anatolia and Turkey’s Mediterranean region, shortening travel time between the cities of Konya and Alanya. Cantilever forming travellers and Doka’s automatic climbing formwork Xclimb 60 were part of the construction solution. The viaduct is nearly 1.4km long and carried by two abutments and eight piers, stret

The original steel truss affair across the St Lawrence River and the adjacent St Lawrence Seaway canal is “a lifeline for residents and businesses” in greater Montréal, according to the national Auditor General - the public sector spending watchdog. “It accommodates
