GLOBAL engineering and environmental consultancy RSK Group has expanded its Australian rail, transport and digital advisory footprint by acquiring Perth-based consultancy BlueFin3.
The deal strengthens RSK’s capabilities across rail, resources, transport and infrastructure markets while bolstering its presence in Western Australia and supporting its broader growth ambitions across the Asia-Pacific region.
Founded in 2022, BlueFin3 employs around 50 specialists across engineering, advisory and digital disciplines, providing services including systems engineering, rail signalling, safety and assurance, operational readiness, project management, data analytics, automation and artificial intelligence.
The company has established a client base spanning major rail, mining and infrastructure operators, including CBH Group, Rio Tinto, BHP, Hancock Iron Ore, Arc Infrastructure, Alstom, Hitachi and the Public Transport Authority of Western Australia.
RSK said BlueFin3’s expertise would complement its existing multidisciplinary operations in Australia, creating opportunities to support projects from early concept development through to operational readiness and digital enablement.
BlueFin3 has been involved in several significant rail and mining projects, including CBH Group’s rail fleet replacement program, BHP’s rail technology transformation, Rio Tinto’s AutoHaul rail operations in the Pilbara and Hancock Iron Ore’s Autonomous Haulage System project.
RSK Group chief executive Alan Ryder said BlueFin3’s specialist technical capabilities aligned with key sectors driving Australian growth.
“BlueFin3 brings together engineering, advisory and digital expertise in sectors that are central to Australia’s growth and RSK’s growth across the country,” Mr Ryder said.
“Its strong client relationships, specialist technical capability and experience across rail, transport, resources and infrastructure make it a valuable addition to our Australian and Asia-Pacific platform.”
BlueFin3 director Warren Burnett said joining RSK would provide greater scale while maintaining the consultancy’s existing culture and client focus.
“Joining RSK gives us the scale and wider network to build on the strong foundations we have established while retaining the employee-driven culture, technical excellence and responsive service that define BlueFin3,” Mr Burnett said.
“Our leadership team will remain with the business, providing continuity for our clients and colleagues as we pursue new opportunities across Australia and the wider region.”
RSK divisional and board director Steve Abbott said the acquisition would enhance the group’s ability to deliver integrated solutions for complex transport and infrastructure projects nationwide.
“BlueFin3 adds specialist expertise in systems engineering and assurance, signalling, operational readiness, human factors, data and automation,” Mr Abbott said.
“Its strong position in Western Australia complements RSK’s wider Australian network and creates opportunities to provide more integrated support for complex rail, transport and infrastructure programs across the country.”
Founded in 1989, UK-headquartered RSK Group comprises more than 300 companies and employs over 17,000 people globally. RSK Australia was established in 2021 and includes a range of engineering, environmental and infrastructure businesses operating across Australia and New Zealand.
