Custom panel design and manufacture to support 27 kilometres of tunnel construction – enabling safe, efficient lighting across the underground Snowy 2.0 network.

As part of enabling works for Snowy 2.0, FGJV required a robust temporary lighting system to support tunnel-boring and lining across 27 kilometres of underground works. To meet this need, PHE Group was engaged to design and construct tunnel lighting boards suitable for high-reliability use in challenging, moisture-prone environments.

Fabrication and testing were completed in one of PHE Group’s Queensland-based workshop, with panels transported to site for installation during tunnelling operations. The project demanded durable construction, consistent supply, and careful sequencing to align with tunnel advancement.

Project Scope

Design and manufacture of approximately 90 tunnel tunnel lighting boards for use during TBM and lining operations.
Fabrication of 4x transformer panels to distribute power across lighting networks.
Pre-delivery testing and quality checks completed prior to site mobilisation.

Outcomes and Benefits

Panels were designed for harsh underground environments with high humidity and limited access.
In-house engineering and build process streamlined production and QA controls.
Delivered through PHE's workshop to maximise build consistency and delivery efficiency.
Compact, modular design simplified installation and maintenance within the tunnels.
Improved site readiness by delivering fully tested panels to meet installation milestones.
Strengthened PHE Group’s fabrication and delivery credentials under FGJV for Snowy 2.0.
