Production

What does the prefabrication stage in CONTRACK technology look like?

1. Preparation

At the preparation stage, all technical parameters of the elements are precisely defined: slab dimensions and weight, types of reinforcement, surface texture, and geometry (including cant and curves). The range of possible solutions is determined based on applicable guidelines.

At the same time, design documentation and interdisciplinary data are analyzed, enabling the identification of potential conflicts and addressing them already at the design stage.

2. Design

Based on the adopted assumptions, detailed design documentation for the prefabricated elements is developed, taking into account all technical, structural, and interdisciplinary requirements. At this stage, solutions are refined, including the layout of reinforcement, technological openings, and lifting systems.

For tram and railway infrastructure, the prefabrication documentation is always aligned with the steel track design, ensuring system consistency and proper interaction between all structural components.

The design process concludes with verification and approval by the client, which forms the basis for starting the prefabrication stage.

3. Slab Prefabrication and Turnout Production (or other steel components, if applicable)

Once the documentation is approved, the prefabrication process begins. Prepared reinforcement is placed on production tables, where the concrete part of the element is produced in accordance with the design and technological standards.

During production, all required openings, ducts, and elements resulting from interdisciplinary coordination are executed.

Precision and Repeatability

The production process, supported by advanced technological supervision and close design cooperation, enables precise replication of the geometry of rail-road systems or any specialized surface (such as bus bays or industrial floors).

Integration of structural components (large-format reinforced concrete slabs and the steel structure) can take place either during prefabrication or directly on site. As a result, ready-made modules are delivered to the construction site, allowing for efficient assembly — almost like fitting together prefabricated blocks or puzzle pieces.

This approach simplifies the installation process, significantly accelerates it, reduces the risk of execution errors, and minimizes the number of personnel required for assembling key infrastructure components.
