The pylons of the 3rd Bosphorus Bridge are unique and extremely complicated due to the inclined conical shape and the numerous embedded items. PERI ACS system was the right decision for this one of a kind bridge project because of the huge experience of PERI. Getting a competent and comprehensive support inside our tight schedule and providing completely safe working platforms at all levels and at any height was other positive aspects of PERI ACS system.

PERI oplossing

  • Efficient formwork concept with ACS self-climbing system and VARIO GT 24 wall formwork for the upper area of the pylon
