Zinfra, one of Australia’s leading utility infrastructure service providers, has been awarded the power utility relocation work for the West Gate Tunnel Project.
The contract was awarded 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 March 2019, with completion due at the end of November.
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 325m 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).
Peter Iancov, Zinfra’s Managing Director, said, “This contract award 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.”
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.
