Zinfra has been awarded the major power utility relocation work through CPB Contractors and John Holland’s Joint Venture, the construction contractor appointed to build the West Gate Tunnel.
This is an enabling piece of work for the project, with Zinfra engaged to deliver a significant amount of work on the AusNet portfolio. This includes realigning the AusNet 220kv transmission line assets which run along the West Gate Freeway, allowing the widening of the current freeway and the greater project to get underway.
Preliminary works commenced early March, with completion due end of November this year.

The contract includes lattice tower decommissioning, to be replaced with a combination of monopoles and new lattice towers, and reconductoring of the lines. A critical component of delivery will include the substantial freeway crossing of the West Gate Freeway with a line span reaching approximately 325 metres over existing traffic lanes, with the freeway kept operational during peak periods. The 220kV line will then feed into AusNet’s Brooklyn Terminal Station (BLTS).
Zinfra’s MD Peter Iancov says the contract reaffirms Zinfra’s market leading transmission capability and experience, including highly complex brownfield environments.
“It also demonstrates our ability to engage in collaborative client relationships to meet current market demands, while mobilising a large team of highly skilled transmission linesmen to meet project needs,” he said.
The win is also a significant step forward for Zinfra as it extends its expertise, scale and end-to-end service offering on utility infrastructure in adjacent sectors across Australia.
