At the Waimarie Science Hub at New Zealand’s Lincoln University, the project team achieved something extraordinary.
By resolving 80 per cent of coordination conflicts before construction even began, they delivered a world-class facility ahead of schedule, on budget, and with a fraction of the disputes that plague typical projects.
The project averaged just three Requests for Information (RFIs) a week – a metric that points to a level of design clarity and team alignment rarely seen in the industry.
This wasn’t a matter of luck; it was by design. The project stands as proof of the benefits of a modern, digitally enabled approach to Integrated Project Delivery (IPD), moving past the traditional ‘design-bid-build’ approach to instead join all parties together in a collaborative contract.
For Jason Howden, Chief Innovation Officer at collaboration software company Revizto, the Waimarie project is more than a success story; it’s a blueprint for the future, and one that the Australian construction industry can’t afford to ignore.
“This white paper is more than just a document; it’s a call to action,” Howden writes in the foreword to Revizto’s new report, The Integrated Project Delivery Advantage.
“For decades, a dedicated community of innovators… has championed a better way of building. The success of the Waimarie Science Hub is a testament to this belief, proving that IPD isn’t just a theory, but a practical and powerful catalyst for the transformation our industry so desperately needs.”
This transformation is urgently needed because the industry’s default setting is failure, Howden said, pointing to the sobering research of Oxford’s Bent Flyvbjerg. His study of 16,000 projects globally found that a staggering 99.5 per cent failed on at least one of their core promises: budget, time or design specification.
Proven concept, new tools
“The first IPD project I delivered was in 2003 – so two decades ago – and it came in on budget, on time. It was delivered on 2D CAD and although there was a digital component to it, it was the contractual framework that made it happen,” Howden said.
“The last piece of the puzzle is the seamless digital technology that joins all those dots together – it’s what we call IPD 2.0.”
Bringing the contractor and key trades into the design tent from day one collapses the traditional, siloed stages of design, bid, and build into a continuous, collaborative process.
It turns design into what Howden calls “solutioneering”. Instead of architects and engineers finalising a design and throwing it over the fence, the buildability and cost are interrogated and refined in real-time by the people who will actually have to construct it.
This provides genuine cost certainty and de-risks the entire project by identifying and solving problems in the digital realm, where they are cheap to fix, rather than on site, where they cause delays and disputes.
For this to work, however, teams need more than just good intentions. Howden draws a critical distinction between the “passive collaboration” often mandated in contracts and the “active collaboration” required to deliver superior results.
“We often have passive collaboration, where it’s written in a contract that you have to collaborate,” he explained. “Active collaboration is where you’ve created the conditions to have the teams genuinely working together to solve problems, regardless of what the contract says.”
The final barrier to achieving this, Howden said, is not a lack of rules or standards. “The contractual and technical frameworks are there,” he said. “We’ve got the IPD methodology, we’ve got the BIM standards. The last piece of the puzzle is to get people to actively collaborate.”
In practice
Since opening in 2023, the 9450m² Waimarie science hub has won multiple awards, including being named the world’s best education building. But its size and cutting-edge design made it a complex build, with around 200 different end users needing to be briefed at different stages.
For the project, the Revizto platform provided a central hub, described by Howden as a “safe harbour” for the entire team. By federating dozens of different 3D models and 2D drawings into one easily accessible platform, it created the transparency and trust necessary for the IPD model to thrive.
Warren and Mahoney Principal Brad Sara said using Revizto for the task allowed designs and any alterations to be visualised in real time, serving as the key information source and collaboration hub for all parties tracking progress or seeking to understand what was required next.
Trades – including electricians, plumbers and builders – were brought in during the design stage, allowing all shop drawings to be completed ahead of schedule and ensuring all parties fully understood the project before setting foot on site, Sara said. “IPD enabled us to re-scope our design role into the contractor’s world – fewer hours on site, but far more impact upfront – reducing coordination conflicts by over 80 per cent before construction even started.”
Leighs Construction Head of Design Mark Pearson said it was not uncommon to have hundreds of RFIs and deviations from design in the first weeks of construction alone because of coordination conflicts. “But on our project we averaged just three RFIs a week through the build phase. It sounds like common sense, but what we did was to actually focus on design during the design stage.”
“To me, Waimarie is more than just a successful project,” said Leighs Construction Senior Project Manager Simon Chambers. “It’s a blueprint and a proof of concept that shows what’s possible when the right people are brought together early, when collaboration is prioritised, and when the focus is on quality, trust and delivery.”
