The whole Midfield Terminal Building project is expected to be 70 per cent complete by the end of 2015.
The 20,000-tonne curved roof is the centrepiece of the Dh10 billion MTB project and the most complex part of its engineering.
It features the world’s longest indoor arch at its centre, which will be 52 metres tall at its highest point and weigh 1,000 tonnes. The roof will be supported by 18 arches.
To date, the roof has been held in place by 30 steel temporary supports that weigh 14,000 tonnes combined. These will be removed through nine de-propping exercises carried out by a team of 45 specialists using 60 hydraulic jacks.
The removal of the props is expected to take about six months and will be completed by next February. Details
