The PERI formwork solution made a substantial contribution to the successful realisation of this project. The formwork adapted superbly to the changing cross-sections and different inclinations.  High work-rate was achieved as a result of the safe and convenient work processes provided by the PERI ACS self-climbing formwork.

Solución PERI

  • crane-independent ACS self-climbing formwork
  • coordinated formwork and platform execution on all standard concreting steps
  • consideration of the cable outlets on the pylon heads
