PROJECT INFORMATION
Consortium: Budimex S.A., Gülermak S.A., Gülermak Agır Sanayi Insaat ve Taahhüt A.S. s.c.
Implementation period: 2025 - 2026 | Work system: 24/7 production
Resources: approx. 50 Transbet TCS employees
Currently the longest railway tunnel under construction in Poland
The "Podłęże–Piekiełko" project is one of the most important railway investments in Poland in recent decades. The construction of a tunnel drilled using the TBM method under Mount Pisarzowa is a strategic undertaking that will shorten travel time between Krakow, Nowy Sącz and Zakopane, improve regional accessibility and strengthen the national transport infrastructure.
This is an investment of enormous economic and social importance, carried out in difficult mountainous terrain, using the most modern technologies. The project includes 2 tunnels running in parallel (evacuation and railway), and about 50 Transbet TCS employees are employed in the implementation.
Each segment welded in 3 types: Type 1 - basic reinforcement, type 2 and type 3 - reinforced reinforcement used in critical tunnel zones (e.g. evacuation exits). Segment A serves as the key for the entire ring.

Transbet TCS is responsible for the production of reinforcement cages for both tunnels - railway and evacuation. The scope of work includes steel preparation, welding in certified technology, quality control and delivery logistics. Each element is created in accordance with rigorous standards, and the schedule is constantly monitored.
As part of the project, steel racks and universal molds for welding reinforcement cages were made. The molds are equipped with color markings of bar positioning points, described in welding instructions, which ensures precision and repeatability.
The organization of production halls was also designed, guaranteeing work ergonomics and optimal placement of workstations. A storage system compliant with the FIFO principle was introduced, enabling identification of cages by production date and type, which minimizes the risk of corrosion and ensures continuity of deliveries despite the varying pace of tunnel drilling.
The tunnel drilling works are carried out around the clock, 7 days a week, without breaks, which requires perfect coordination of all deliveries and processes. The schedule is tight, and every hour counts. Delays in one area can affect the entire project.
This is work under constant time pressure, where flexibility and quick response are key.
