Telecommunications and Data-transmission Towers

be topped with a 54-metre steel tube mast. The contractors' tender was eventually won by the Potiber—ÁÉV No. 31 consortium with a complex comprising six buildings to be constructed around the tower interconnected by neck mouldings.

The 154-metre-high transmission tower is anchored to the ground by a 2.5 metre thick concrete disc. It is on this that the sixteen reinforced-concrete sections of a polygonal cross section were placed. Reinforced with steel nets, the sections, whose walls are 37.5 centimetres thick, were prefabricated on site with sliding- shutter technology. The shuttering was lifted in four-metre high increments with the help of a creeping crane fixed to the tower body. The steel unit is made up of a tube 2,500 millimetres in diameter, which continues in a steel framework with a 1,400 by 1,400 and then an 800 by 800 millimetre cross section. The balconies and internal ceilings are made of steel. The closed transmission room is covered with a brass sheet.
