Pavel Kouba
Project Manager

PERI provided the most cost-effective formwork solution for constructing the piers and superstructure.  Using the PERI composite formwork carriage resulted in considerable cost savings for us.  In addition, normal rail traffic operations could be maintained during the entire construction period.

PERI solution

  • system solution with composite formwork carriages for the substructure
  • customised and prefabricated VARIO GT 24 elements
  • CB/VARIO climbing formwork for the pier shafts
  • suspended SB brace frame system for the pier heads with doubling on the VARIO elements
  • tie points tailored to the construction project
  • main load-bearing members and separating wall of the pier heads formed and concreted in one pour
