Rui Correia
Technical Manager

The VARIOKIT system played a key role in mastering the challenges presented during the construction of the station - the PERI formwork carriage adapted perfectly to suit the different geometries. With the fast concreting cycle sequence of 15 m per week, the project could be completed ahead of schedule in spite of the high technical and quality requirements.

Solución PERI

  • Customised VARIOKIT formwork carriage construction in order to cost-effectively realise both cross-sectional variants with the help of the same system components and formwork segments.
  • Hydraulic operability for convenient working operations and fast implementation.
  • Economically-optimised tunnel formwork solutions for the complete extension project with a total of 4 formwork carriages, tailored to suit the range of different requirements.
  • Team of PERI engineers from Algeria, Portugal, Spain and Germany.
