A new report from engineering and consulting firm Egis is calling for a fundamental shift in how infrastructure is planned and delivered across the UK and Ireland, warning that project-by-project delivery is no longer capable of responding to mounting climate, economic and societal pressures.
The white paper, From projects to programmes: how infrastructure can keep pace with a changing world, argues that infrastructure systems must be managed as long-term, interconnected networks rather than isolated assets. According to Egis, ageing infrastructure, climate risks and uncertain funding models are already placing increasing strain on transport, energy, water, digital and urban systems.
The report draws on insights from specialists across multiple infrastructure sectors and suggests that maintaining current delivery models will lead to higher costs, greater disruption and increased operational risk over time.
Francois Basselot, managing director of Egis in the UK and Ireland, said: “The challenges facing infrastructure today don’t show up one project at a time. What’s driving change affects whole networks, yet we still tend to plan and build as if each project stands alone.
“When that happens, we’re constantly catching up instead of looking ahead. This report is about changing that way of thinking by moving away from short-term fixes and towards long-term stewardship of infrastructure, before today’s pressures become tomorrow’s failures.”
The report states that much of the infrastructure currently relied upon across the UK was designed for different demographic, environmental and economic conditions. Population shifts, increasing frequency of extreme weather events and growing pressure on public spending are exposing the limitations of ageing networks.
Egis argues that the underlying issue is not simply the condition of individual assets, but the continued treatment of infrastructure as disconnected projects rather than integrated systems. According to the report, this approach can make it more difficult to manage risk, build resilience and direct investment effectively.
The publication identifies five areas where infrastructure planning and delivery could change. These include earlier engagement with communities to better understand patterns of use, greater focus on long-term outcomes rather than standalone assets, and planning at a system-wide level rather than through isolated schemes.
It also calls for wider use of data and digital tools to support long-term decision-making and recommends maximising the performance of existing infrastructure through reuse, refurbishment and targeted upgrades.
The report suggests these changes would allow infrastructure networks to adapt over time while reducing the need for reactive interventions and emergency repairs. It also points to examples from the UK, Ireland and mainland Europe where programme-led approaches have already been used across transport and urban infrastructure systems.
Examples referenced in the report include adaptive reuse of existing assets, integrated transport planning and digital modelling tools used to anticipate operational risks before failures occur. Egis argues that many of the technical solutions already exist, but current delivery structures often delay investment until infrastructure problems become critical.
The report comes as governments and infrastructure owners face increasing pressure to improve resilience against climate-related disruption while maintaining public services and managing costs. In recent years, flooding, overheating and network disruption have affected transport systems, utilities and public infrastructure across the UK.
Infrastructure planning has also become increasingly tied to wider net zero and adaptation targets, particularly as public authorities seek to modernise systems while reducing emissions and resource use.
The report calls on policymakers, infrastructure owners and delivery teams to adopt what it describes as a programme-led approach centred on long-term stewardship. Egis says this would allow organisations to prioritise investment based on overall network performance rather than isolated project timelines.
Basselot said the industry now faces a choice between continuing to respond reactively to emerging pressures or adopting planning models designed to anticipate long-term change across entire systems.
The report concludes that infrastructure networks will need to evolve continuously over coming decades if they are to remain reliable, resilient and financially sustainable in the face of changing environmental and societal demands.
