The final result speaks for itself: The PERI employees were always willing to rise to the complex challenges. We were able to bring this project to a successful conclusion and adhere to the demanding quality standards as a result of our collaboration with both the PERI Engineering Office and the production department.

PERI solution

  • Comprehensive solution with project-specific, adapted formwork and scaffolding materials
  • Use of CB Climbing Formwork combined with the VARIO GT 24 Girder Wall Formwork to create the internal core which extends vertically upwards
  • Creation of a 3D planning model and PERI special-purpose formwork for the external pipe
  • Cut-to-size plywood panels using CNC cutting and special assemblies
  • Preliminary in-house testing of the special-purpose formwork at PERI sites
  • Installation of the five cantilevered platforms using MULTIFLEX Girder Slab Formwork combined with components of the VARIOKIT Engineering Construction Kit, PERI UP Flex and other slab props
  • Assembly of safe working platforms consisting of PERI UP Flex working platforms supported by system components of the VARIOKIT Engineering Construction Kit and a Brace Frame SB-2
  • On-site project support provided by PERI supervisors
