CCL supplied its XF flat slab bonded post-tensioning system and equipment for the first Bulgarian Skyscraper, Sky Fort, located in the capital, Sofia.

Sky Fort stands 202 metres tall and is currently the tallest building in Bulgaria, as well as being one of the few buildings in South East Europe to reach 200 metres. The tower has 49 levels above ground and three underground floors.

To provide additional corrosion protection, CCL’s encapsulated XF system has been installed for the three basement slabs.

The building comprises comfortable office space with incredible views towards Sofia, Vitosha mountain, and the Sofia valley. A restaurant and an observation platform are located at the top of the building.

Advanced technologies to improve the structural performance have been implemented throughout the structure including seismic resistance, an energy-efficient facade, and high-speed elevators.

Sky Fort was completed early 2022.
