Coordination with utility installations, traffic signaling, and SCADA systems

Design scope:

Contact and cable network – from conceptual design to implementation plans and technical specifications
Rectifier stations – design of traction systems, grounding, and protection against the backflow of currents back flow
Modernization of tracks – renewal of lines, grounding, drainage, and insulation
System integration – synchronization with traffic signaling, public lighting, and SCADA monitoring
Compliance with regulations – design documentation according to HRN/EN, IEC standards, and client requirements (GPP, ZET, HŽ Infrastructure)

Our supervising field engineers monitor all phases of execution, following European practices:

Execution Quality control – alignment of contact lines, proper installation of cable systems
Technical compliance – certificates verification, equipment and materials testing
Participants' coordination – construction, electrical, and traffic teams under unified supervision
Execution Safety – procedures control when working under voltage and at height
