Kičevo Podvis Motorway Bridge, North Macedonia

On the first section through the mountainous region of western Northern Macedonia, the new motorway crosses a total of 14 viaducts. On a length of approx. 10 km, around 4,000,000 m³ of earth had to be excavated and a total of 150,000 t of concrete and 15,000 t of reinforcement were subsequently processed.
The left, right and centre sections of the bridge superstructure were sub-divided into 64 concreting sections and simultaneously realised using a total of four VBC Balanced Cantilever Carriages.
With the balanced cantilever method, the superstructure is symmetrically realised on both sides in the form of a balance beam - starting from the rigidly connected pier.
Due to the high degree of flexibility of the balanced cantilevered carriage, the system could be quickly adapted in order to match the different cross-sections whereby individual offset cycles were accelerated and work processes optimised.
In particular, the complete hydraulic alignment and adjustment as well as the simple moving procedure of VBC Carriage shortened the execution times. This allowed the four cantilevered elements to be realised in a 7-day cycle.
For constructing the bridge piers, TRIO Panel Formwork and VARIO GT 24 Girder Wall Formwork on horizontally positioned SB Brace Frames were used as well as a combination consisting of SCS and CB 240 Platforms.

お客様にとっての価値

  • Time-savings through simple, fast adaptation of the balanced cantilever equipment to suit the changing bridge cross-section
  • Reduced working time thanks to fast shuttering and striking operations with one hydraulic solution
  • Reduced crane time due to independent moving procedure of the VBC Cantilevered Construction Carriages
  • Economical solution through the rentability of the system components
  • Continuously optimised workflows through on-going site support
  • Simple communication process due to the execution and logistics solution from a single source

Together with the PERI expert team of engineers, we quickly defined the technical solutions for the realization of the bridge project. Extremely important to us was the on-going site support when the VARIOKIT was being used.

提案内容

  • Project-specific cantilever construction solution based on the VARIOKIT Engineering Construction Kit for the execution of the bridge superstructure
  • Parallel use of four balanced cantilevered carriages for accelerating execution times
  • Individually-adapted climbing formwork solution for cost-effective construction of the bridge piers
  • Just-in-time delivery of the required formwork and scaffolding materials
  • Continuous on-site support in order to optimise work operations
