Wellington Mt Victoria Tunnel & Terrace Tunnel

DSI Facades

  • Technical Support for the design and installation of the tunnel framing

Project details

The tunnel systems were near the end of their design life, and the existing infrastructure falls short of the standards expected of modern urban road tunnels. Upgrading them involves construction of new tunnel infrastructure including fire control systems, ventilation systems, lighting, drainage and seismic upgrades.

Innovative ideas

The process combines a risk-based analysis of the fire and life safety situation in the tunnel with the ‘safety file’ approach adopted in Europe and a scientific decision making process to rank and select alternatives.

The outcome of the Terrace Tunnel refurbishment is a ‘smart tunnel’ that can be operated and maintained efficiently, with inbuilt emergency systems that can detect and minimise loss in the event of an incident in the tunnel.

Panels
Conditions for driving through the tunnel have been improved with 1,000 light-reflecting white panels, VitraPanel, beside the carriageway, a new paint palette and inductively powered LED road markers along the sides and centreline. The panels are fire-resistant, adding to the tunnel’s safety profile.
