PERI planned and supplied the complete formwork and scaffolding solution for the implementation of the dam. It was always possible to flexibly adjust the systems, which were used, to the particular pouring section and the different requirements.

PERI solution

  • TRIO side formwork for layer-by-layer placement of the rolled concrete
  • single-sided SKS climbing formwork solution for the 2 m thick structural concrete layer with pouring cycle heights of 2.40 m
  • horizontally used brace frames at the run-off channel
