A recent survey of senior executives in the private and public sectors has exposed alarming challenges for infrastructure megaprojects.
The results, collected and analysed late in 2024, highlight persistent underperformance and fundamental flaws in how high-value infrastructure projects are managed in Australia.
While the findings mirror those in previous studies, they reveal that many of the long-standing issues remain, incurring substantial avoidable costs to the sector and nation.
The research confirms a troubling trend that Australians might have anecdotally thought to exist: that large infrastructure projects frequently exceed budgets and timelines.
A striking 80 per cent of respondents to the survey agreed or strongly agreed that large infrastructure projects are often over budget and behind schedule. This poor performance has persisted for decades.
Investors lamented the widespread lack of realistic project scopes, fit-for–purpose designs, suited to current and emerging needs, and accurate costings, leading to poor performance. Failed planning at the outset was reported to be causing costly variations and delays.
Excessive government interference, particularly from ministers and fragmented control across departments, related to delays and was seen as a significant barrier to project success. Many criticised the excessive focus on cost-based tendering at the expense of value and effective risk collection.
Despite evidence that well-governed, alliance-based contracting consistently outperforms other methods, its use has declined due to shifting political priorities. Investors expressed a preference for practical and functional contracts that support realistic scopes of work and better balance cost considerations with long-term project outcomes.
Professional services firms working in the built and natural environment have a vital role in managing these issues as they play dual roles in the dynamic major project delivery ecosystem. As providers of professional services, consulting engineers and urban planners are key agents for driving change.
Professionalism and transparency are crucial to ensure stakeholders have realistic expectations from a project’s get-go. Predictive modelling and scenario analysis can also help identify risks early and propose proactive mitigation strategies.

Performance improvement not incentivised
The survey highlights a critical issue: a lack of incentivisation for performance improvement along the value chain. When respondents were asked about the extent to which improved performance was incentivised, 68 per cent said, “not at all” or only “to a small extent”.
These issues are creating poorly aligned goals, where stakeholders often aim for minimum requirements rather than striving for excellence.
This impacts project outcomes and creates challenges like misaligned goals, where stakeholders aim for minimum requirements over functional and aesthetic excellence.
Each party focuses on its narrow responsibilities rather than the overall project success, leading to disjointed efforts and inefficiencies.
The ‘race to the bottom’ mentality during the tendering process, where firms submit unrealistically low bids without fully considering potential risks and challenges, also contributes to poor communication and siloed thinking.
Additionally, respondents noted that innovation was often assumed rather than deliberately acknowledged, rewarded or leveraged by clients. This meant clients were not incentivised to work creatively, leading many firms to lack the motivation to go beyond the minimum requirements.
This dynamic reinforced the industry’s risk-averse and cost-driven approach, creating a disincentive for forward-thinking solutions.
Two takeaways
The research gathered insights from 125 senior executives in the delivery chain of high-value infrastructure projects, including investors, designers, planners, constructors, operators, end-users and owners.
Beaton conducted the survey on behalf of the high-value infrastructure project (HVIP) partnership, comprising experts from Innergise, Autodesk, Cambridge University, Max Hardy & Associates, and Beaton.
The partnership aims to address these critical issues and drive improvements in the design and delivery of infrastructure projects across Australia. This survey’s findings underscore the urgent need for smarter planning, effective contract and construction management, and a collaborative approach to enhance infrastructure project outcomes.
Two key takeaways stand out. One: incentivisation of performance improvement along the value chain is middling at best. And two: it’s what people don’t say that also stands out.
For example, data is not seen as a problem in performance, yet it’s not being used well to inform performance improvement.
The research should help to catalyse an evidence-based overhaul to improve how high-value infrastructure projects are run and incentivised in Australia.
