M-8 Road Bridge, Szczecinek By-Pass, Poland

For the M-8 road bridge, PERI engineers planned a project-specific shoring and formwork solution. The heavy-duty scaffold construction, consisting of VRB Heavy-Duty Truss Girders and VST Heavy-Duty Towers, safely transferred the high loads via long spans into the ground.
For forming the superstructure comprised of bridge beams and carriageway slab, the planners combined VARIOKIT formwork units with VARIO GT 24 Girder Wall Formwork system components.
The implementation plan featured two independent bridge superstructures with a pre-stressed, twin-webbed T-beam cross-section. The two superstructures were alternately concreted whereby the formwork and shoring were placed in an offset position from one bridge segment to the other.
Units pre-assembled at the PERI assembly hall were connected on-site to form pairs of girders with a total length of 20.50 m and 25.50 m respectively.The VRB Heavy-Duty Truss Girders were then lifted as a single unit by crane and mounted on the VST Shoring Tower Frames.
For accelerating the final assembly, PERI also delivered pre-assembled formwork units. The PERI formwork erection process ensured accurate assembly and punctual scheduling.
PERI engineers support the construction team throughout the entire construction process with on-time logistics and on-site project support to ensure that all requirements could be met as well as making sure that the tight construction schedule was maintained.

Projektinformation

Plats: Szczecinek, Polen

  • 160 m long road bridge with two lanes in both directions
  • Core element of a 12 km long by-pass circumventing the town of Szczecinek as part of the S-11 highway expansion project

Krav

  • Challenging bridge construction in the wetlands area surrounding the Wilczy Canal
  • Difficult ground conditions demanded large span widths of 20.50 m and 25.50 m for the shoring – without any intermediate support
  • No suitable assembly area on the construction site

Kundfördelar

  • Cost-effective solution for the heavy-duty shoring due to the use of system components
  • Time and cost savings through an efficient overall concept for the construction of the bridge
  • Maintaining the tight construction schedule due to pre-assembly at PERI, on-time logistics and on-site continuous project support
  • Low storage costs due to reduced on-site material requirements
  • Efficient work operations due to low weight, high degree of modularity as well as simple and fast assembly with fitting pin connections
  • Crane time savings
  • Safe access to all working areas thanks to integrated PERI UP Stairs

Together with PERI engineers, we have developed the optimal solution for this demanding project. The usage of VRB Truss Girders made it possible to efficiently carry out work despite difficult ground conditions. Due to the delivery reliability of the required formwork and scaffolding material, we were able to keep to the tight schedule. Another advantage of the cooperation was the constant construction supervision by the PERI supervisors, who ensured the correct assembly and maintenance of the material as well as training on the construction site.
