Western Harbour Tunnel

Western Harbour Tunnel is a major transport infrastructure project that will make it easier, faster and safer to get around Sydney.

As Sydney continues to grow, with more and more trips being made, so will the challenges to our transport network. Western Harbour Tunnel is key to delivering the transport vision for Sydney. It will change the way people move around Sydney and how people travel between the North Shore, the central business district (CBD) and Western and Southern Sydney.

With Western Harbour Tunnel, people will spend less time in traffic and have more time for themselves and their families. Western Harbour Tunnel includes over six kilometres of mainline tunnels as well as upgrading over nine kilometres of surface roads. Largely underground, the Western Harbour Tunnel has been designed to have minimal impacts on communities and to minimise property needs.

Western Harbour Tunnel will:

  • Create a western bypass of the CBD and take pressure off the congested Sydney Harbour Bridge, Anzac Bridge and Western Distributor
  • Integrate with public transport, improve travel times and boost reliability for cross-harbour trips and the broader network
  • Provide core capacity that enables improved links across Sydney


VICTOREM were engaged by estimating specialist Ranbury and Slattery to support them with the Pre-tender estimate for the project.

Working closely with the TfNSW, Ranbury and Slattery, our team held a number of risks workshops to understand the threats and opportunities to the project. This information, long with the estimate was to support the provision of the Quantitative Risk Analysis (QRA).

Our team successfully achieved this key important task within the desired timeframes, allowing TfNSW to move forward fully understanding the risks for the project and the contingency provisions required for successful delivery of the project.
