Tough assignment on CMA Tower
Set to top out at 400 m, the 76-storey CMA Tower in Saudi Arabia will be the tallest building in the city of Riyadh, in whose King Abdullah Financial District it stands. The CMA Tower is being built by SBG, a firm with a huge fund of experience in highrise construction. The tower stands out for its gigantic nine-sided CIP concrete core, whose 40 m cross-section makes it big enough to be a skyscraper in its own right. An ingenious formwork solution from Doka is in use for the 100 casting sections. At present, SBG has an uncommonly tough challenge to deal with: incorporating a three-storey-high steel construction into the CIP concrete core.
