The MacIntyre Wind Farm is one of Australia’s largest onshore wind developments, playing a critical role in the country’s transition to renewable energy.
Located in Queensland’s Southern Downs region, it includes 162 wind turbines with a generation capacity of 923MW. As part of a broader renewable energy zone, the project is helping strengthen Australia’s energy network while supporting long-term decarbonisation goals.
IBR partnered with ACCIONA to deliver reinforcement across turbine foundations and associated civil works, contributing not just to supply, but to how the project was delivered.
Scaling supply to match an ambitious program
Delivering a project of this size required more than volume. It required consistency, coordination and the ability to keep pace with a demanding construction schedule.
IBR supplied approximately 18,000 tonnes of steel, maintaining delivery rates of up to 1,500 tonnes per month to support continuous activity across multiple work fronts.
Through careful planning and close alignment with site requirements, reinforcement was delivered when and where it was needed, helping maintain momentum and avoid disruption.
As Mike Jostsons, IBR Business Development Manager – Energy, explains:
“On a project of this scale, it’s not just about how much steel you supply, it’s about how reliably you can deliver it. Consistency across the program was critical to keeping construction moving.”
Managing complexity through coordination
The scale and technical requirements of the project introduced several operational challenges, including high-volume supply across multiple processing locations, complex reinforcement configurations, and strict compliance requirements for lifting systems.
These were addressed through structured planning and close coordination across all stakeholders. Early alignment with operations teams ensured production capability matched project demand, while targeted investment in plant, jigs and processes supported specialised fabrication requirements.
“There was a lot of complexity behind the scenes,” Mike explains. “But with the right planning and coordination, we were able to keep supply aligned to the program the whole way through.”
Improving constructability through 3D modelling
The MacIntyre Wind Farm also marked a step forward in how reinforcement is detailed and delivered on large-scale renewable projects.
For the first time in this context, a full 3D modelling approach was applied to reinforcement detailing. This enabled early clash detection, improved constructability, and more accurate production documentation.
By resolving issues before materials reached site, the project reduced rework, improved sequencing, and created a more efficient construction process overall.
A model for future renewable projects
The MacIntyre Wind Farm demonstrates what can be achieved when large-scale supply, early engagement and practical innovation come together.
By combining detailed planning, smarter delivery methods and a collaborative approach, IBR supported a project that is helping shape Australia’s renewable energy future.
The learnings from this project, particularly around early engagement and 3D modelling, are now informing how wind farm projects are delivered moving forward.
