Avantaje client

  • Due to the high flexibility of the VARIOKIT system, as well as the high load-bearing capacity of the system components, the inner lining of the tunnel could be executed very cost-effectively
  • The low weight of the timber formwork resulted in enormous weight savings and thus reduced work requirements and logistics costs
  • Thanks to the VTC Telescopic Post, the formwork could easily be adapted to accommodate the new cross-section with relatively little time and effort
  • The prefabricated formwork elements delivered directly to the construction site simplified jobsite logistics
  • Through the know-how and the expertise of the PERI engineers, construction process could be continuously optimised
  • Accelerated shuttering and striking procedures through the hydraulic support of the VTC Tunnel Formwork Carriage
