Site Management

With the VST heavy duty tower we were able to adapt the support to the different heights. The assembly work was safe and quick thanks to the pre-assembled units.

PERI solution

  • 30-m-high falsework of VARIOKIT heavy duty towers
  • CB/VARIO climbing formwork for the piers
  • suspended SB brace frames for the pier tables
