The Rozelle Interchange is part of an intricate tunnel system, involving multiple underground routes and intersections. The installation of the fibre network had to account for complex routing, limited space, and integration with various mechanical and electrical systems.

Project Challenges

• Engineering Complexity: The Rozelle Interchange’s intricate network of underground routes and intersections required precise planning for fibre optic cable routing within confined spaces and integration with existing mechanical and electrical systems.
• Coordination with Concurrent Projects: Interfacing with multiple infrastructure projects necessitated seamless collaboration to ensure system compatibility and integration across the entire tunnel network.
• Safety and Logistics: Installing the fibre optic network involved working in challenging underground environments, including hauling cables down multiple shafts, which demanded rigorous safety protocols and logistical coordination.

ROC Approach

• Comprehensive Site Assessment: to map optimal fibre optic cable routes, ensuring efficient integration with existing infrastructure.
• Strategic Planning and Coordination: Engaged in continuous collaboration with various contractors and stakeholders to synchronise activities, particularly in areas where the interchange connected with other projects.
• Safety-Focused Execution: Implemented stringent safety measures and conducted daily interface meetings to manage the complexities of installing cables in confined underground spaces.

Results

• Enhanced Operational Efficiency: The modern fibre optic network supports high-speed data transmission, facilitating real-time monitoring and control of tunnel operations.
• Improved Safety Measures: The integration of extensive CCTV coverage and reliable communication systems bolsters incident response and overall tunnel safety.
• Timely Project Completion: Despite the project’s complexity, the fibre optic installation was completed ahead of schedule, contributing to the overall progress of the WestConnex development.
