Infrastructure Asset Lifecycle Management: Why Equipment-as-a-Service Matters Beyond the Funding Gap

Infrastructure asset lifecycle management helps public infrastructure owners plan, maintain and renew critical assets more reliably across their full lifecycle. It connects asset condition, risk, service outcomes, delivery capacity and equipment readiness so that infrastructure investment can translate into measurable public value. For transport authorities, utilities and public-sector infrastructure operators, the challenge is no longer only how to close the funding gap. It is also how to use capital, labour, contractors, data and specialist equipment more effectively, including through Equipment-as-a-Service models that provide access to the right equipment, at the right time, under the right service conditions. 

Infrastructure funding gap: why capital is not the only constraint 

Reliable public infrastructure depends on converting approved investment into delivered services, not on capital alone. Aging assets, climate exposure, fragmented governance and weak condition data all play a part. So do skills shortages and constrained construction capacity. 

The financial pressure is substantial. In 2024, the OECD estimated that the cumulative gap between expected infrastructure investment and the investment required to support the Sustainable Development Goals could reach USD 18 trillion by 2040. It cited annual gaps of approximately USD 170 billion for Africa and USD 270 billion for Latin America. These figures describe broad investment requirements rather than a directly measurable infrastructure maintenance backlog. 

Advanced economies are not exempt. In 2025, the American Society of Civil Engineers gave United States infrastructure an overall grade of C, it's highest since the assessment began in 1998. It nevertheless estimated a ten-year investment gap of about USD 3.7 trillion under continued recent funding levels. Stormwater and public transit received D grades, and nine of the eighteen assessed categories remained in the D range. 

Europe faces a related problem: extensive, heavily used and often aging transport networks. The revised Trans-European Transport Network framework recognizes maintenance and the structural stability of bridges and tunnels as explicit policy concerns. The central challenge is therefore how to convert scarce capital, workforce capacity, and operational resources into reliable services. 

Why infrastructure maintenance backlogs grow 

Infrastructure deterioration is physical, but infrastructure underperformance is often institutional. Deterioration becomes a public-service crisis only when it is not identified, prioritized, or addressed in time. That depends on condition information, risk models, funding continuity, engineering capability, procurement and access to equipment. 

England illustrates this point. According to the National Audit Office in 2024, England's approximately 183,000 miles of local roads represent 98% of the country's road network, with annual central capital funding reported at GBP 1.1-1.6 billion. Road conditions were declining, and the repair backlog was increasing. The Department of Transport also lacked sufficient information to know whether its funding was improving outcomes. 

The Public Accounts Committee later cited fragmented funding, short planning horizons, incomplete data, and reactive pothole repairs. It referenced an industry estimate of more than GBP 15 billion to restore local roads to good condition. Funding still matters, but money has lower marginal value without a credible asset register, consistent condition assessment and a program-level delivery plan. 

Delivery capacity is a separate constraint. Australia's five-year major public infrastructure pipeline reported in 2024 was AUD 213 billion. Infrastructure Australia nevertheless identified skills shortages, material costs and stagnant productivity as constraints on delivery. An approved pipeline can exceed the market's practical capacity to execute it. 

Why funding alone cannot solve infrastructure maintenance backlogs 

Additional funding remains necessary in many jurisdictions, but treating it as the only binding constraint is a risk. The World Bank cites International Monetary Fund estimates that countries lose roughly one third of infrastructure expenditure through inefficiency on average. In some low-income settings, estimated losses exceed 50%. Such estimates are cross-country approximations, not predictions for individual authorities. 

The OECD's 2023 governance survey points to similar gaps. Among 33 participating countries, 76% required infrastructure asset management plans. Only 52% continually monitored infrastructure performance against predefined service-delivery targets and expected outcomes. 

How infrastructure asset lifecycle management works in practice 

Infrastructure asset lifecycle management works best as a connected system in which outcomes, risk, interventions, delivery capacity and feedback are managed together. ISO 55001:2024 is the international standard that specifies requirements for an asset-management system. It requires organizations to balance performance, risk and expenditure, and its 2024 edition strengthens requirements on decision-making, value realization, and the Strategic Asset Management Plan. 

Applied prudently, ISO 55001 asset management suggests five connected layers: 

• Define public-service outcomes, such as network availability, structural safety, or journey reliability. 
• Establish a risk-based asset baseline, recording uncertainty explicitly rather than assuming good condition. 
• Convert needs into a multi-year intervention portfolio that plans investment, renewal, maintenance and inspection together. 
• Test the program against delivery capacity: skills, suppliers, permits, access windows, materials, and specialist equipment. 
• Close the operational feedback loop, so results, delays, and cost deviations update future decisions. 

Why Equipment-as-a-Service matters for infrastructure maintenance 

Equipment management belongs to the infrastructure agenda because inspections, maintenance and renewals depend on equipment being available, safe, and ready. A bridge provides a public service for decades; an inspection of vehicle, crane or pump enables the intervention. These are different asset domains, but an inspection cannot happen without calibrated instruments, and a renewal window loses value if a specialist's machine is unavailable. 

Operational readiness is the state in which equipment is technically sound, certified, assigned, and staffed for a planned task. Engine runtime is not productive to utilization, and location proves presence, not readiness. Better information can support capacity assurance, capital discipline, and lifecycle control. 

The evidence does not justify a universal claim that Equipment-as-a-Service will reduce total infrastructure investment. It may help avoid unnecessary purchases, reduce emergency rentals, improve equipment access and make service costs more transparent. Any effect on infrastructure life depends on a longer causal chain, and the lifecycle benefit must exceed the cost of the service model. Equipment-as-a-Service suits intermittent or specialist demand particularly well, but is less attractive for mission-critical or continuously used equipment where ownership, pooling or dedicated capacity may remain more appropriate.
