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. The formwork systems from Doka are in use in many a

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.

    July 4, 2019
    A Demag CC 3800-1 crane with an 84m-long main boom was recently set up in Germany without a Superlift counterweight to save space. The jobsite was the replacement of the old viaduct on the A45 Freeway that spans the Lahn River near Dorlar in Germany. Bietigheim-Bissingen-based crane service provider Wiesbauer solved the site’s space issues by using a Demag CC 3800-1. “This site required us to lift loads of 96-148tonnes at radii of 40-64m, so there was no option but to use a crawler crane in the 650tonne c
