V/Line – Mount Emu Creek Steel Bridge Replacement

V/Line needed the Mount Emu Creek bridge replaced, as it was becoming life-expired. In response to this urgent request, Brunton worked over nine days to complete the project.

Our Solution

• Brunton conducted a site survey to get a comprehensive understanding of the existing bridge dimensions. This informed the 3D fabrication design the team established with Autodesk Inventor – the evolution of traditional 2D-CAD technologies.
• The team fabricated and galvanised the replacement structural steelwork bridge decks in-house, which comprised of over 10,000 parts and weighed at least 160 tonnes.
• Brunton relocated the heritage-listed bridge span to their Somerton workshop for remediation works. Under controlled conditions, the team worked around-the-clock shifts across two days to complete the remediation process.
• To install the new bridge, Brunton coordinated:
  • the removal of around 200 metres of broad-gauge railway tracks
  • the recycling of the sixteen bridge spans that were made redundant during this project.
• They also installed new bearing plates with epoxy embedments at fifteen piers and two abutments. The pre-assembly and installation of the replacement spans comprised of:
  • numerous steel beams
  • steel trough decking
  • formed channel kerbs
  • walkways and handrails.
• Brunton coordinated the upgrade of adjacent level-crossings, including the replacement of:
  • outdated sleepers
  • conducted minor track lifts
  • reinstated asphalt.

Our Results

Brunton’s team delivered this project ahead of the designated deadline, despite the tight timeframe.
