Construction of 2 towers, 143,50m high and 12,80x12,8 m floor plans with internal partitions at the 5th PPC unit in Ptolemaida.
There was a climbing ladder and a lift for the staff. At the lower 40.00 meters the towers would be connected to the building that would be built afterwards.
A special slipform shuttering was made so that horizontal reinforcements protruding from the slipform shuttering were placed in the slide without bending.
During sliding, a special membrane was also placed on the outer surface to create a rough joint surface.Top view of night work
