Rhomberg Sersa Australia (RSA) was engaged by ARTC to deliver complex upgrade works in the Kerrabee Tunnel, located on the Hunter Valley Ulan Single Line. The works
aimed to enhance track reliability and reduce future maintenance requirements in a constrained and high-risk tunnel environment.
The project required careful planning, multi-disciplinary coordination, and robust logistics due to the remote site location and high-risk operational constraints.
Scope of Works
- Tunnel formation excavation and reconditioning Installation of drainage and water management controls
- Rock bolting to secure tunnel structure and improve safety
- Track re-alignment and geometry correction within the tunnel
- Surveying and validation of tunnel alignment and formation
- Delivery of works across four major possessions Continuous monitoring
Key Outcomes
ON-TIME DELIVERY
All works completed across four scheduled possessions, enabling safe return to network operations.
IMPROVED RELIABILITY
Enhanced formation and track alignment significantly reduced maintenance needs and defect risk.
SAFETY-FOCUSED EXECUTION
Multi-disciplinary teams managed high-risk tunnelling activities.
REMOTE SITE LOGISTICS
Robust planning ensured continuous supply of labour, equipment and materials to a difficult access location.
DESIGN INTEGRATION
Works delivered to final design specifications through detailed staging and planning.
