Viaduct Krakow-Plaszow Railway Junction, Poland

Viaduct Krakow-Płaszow Railway Junction - Customized solution through the flexible and modular adaptability of the system.
Viaduct Krakow-Płaszow Railway Junction - The safety was guaranteed through the compatibility with the PERI UP modular scaffolding.
Viaduct Krakow-Płaszow Railway Junction - Construction of the 252 m long crossing over the Krakow-Plaszow railway junction was carried out using 4 VARIOKIT cantilevered construction carriages.
Viaduct Krakow-Płaszow Railway Junction - Heavy railway traffic at one of the busiest stations in Poland remained undisturbed during construction thanks to the PERI balanced cantilever equipment.
Viaduct Krakow-Płaszow Railway Junction - In the foreland area, PERI UP Rosett Flex load-bearing system together with a throughway consisting of HD 200 heavy-duty props was used as shoring solution.
Viaduct Krakow-Płaszow Railway Junction - As part of the Krakow metropolitan railway system (KST) expansion, a 40 m high asymmetrical viaduct pylon was erected in the second phase of construction.

Project data

Location: Krakow, Poland

252 m long crossing over the Krakow-Płaszow railway junction using the balanced cantilever method

Requirements

  • Extradosed bridge with hollow box cross-section
  • Strong asymmetric shape of the superstructure cross-section as well as its variable width along the structural axis
  • Taking into consideration tendons and anchorage points of the stay cables outside of the box girders
  • Ensuring rail operations are not interrupted during construction of the crossing

Customer's benefit

  • Minimization of time and material costs due to the close collaboration between the general contractor, planners and PERI engineers during the planning phase
  • Easy and fast formwork alignment
  • Maximum level of safety for the site team during every phase of construction through the compatibility of the balanced cantilever equipment with the PERI UP modular scaffolding
  • No negative effects on daily train operations during the viaduct construction using the cantilevered construction method
  • On-time realization and according to plan in 2-week cycles despite the difficult boundary conditions

The PERI cantilevered construction equipment used allowed easy and quick formwork alignment as well as providing safe working conditions above the railway. With the help of the balanced cantilever carriage, extremely short concreting cycles as well as punctual realization of the project according to plan are possible. Thanks to the cooperation with PERI, the job could be realized in spite of the complicated infrastructure around the structure.

PERI solution

  • Matching cantilever construction solution on the basis of the VARIOKIT engineering construction kit
  • Customized solution through the flexible and modular adaptability of the system
  • Close cooperation between the general contractor, planners and PERI engineers during the planning phase allowed optimization of the structure´s shape
  • Realization of 5.70 m long concreting sections
