Neglecting infrastructure maintenance isn’t just an inconvenience – it’s a financial and safety crisis. Across the U.S., outdated systems like roads, bridges, and water pipes are failing under the strain of age and increased demand. Here’s why this matters:
- Deferred Maintenance Costs More: A $100,000 repair today could balloon to $762,000 in 30 years.
- Economic Impact: Deteriorating roads alone cost the U.S. economy $200 billion annually in lost time and fuel.
- Safety Risks: Failures like bridge collapses and dam breaches endanger lives and disrupt communities.
- Funding Gaps: Despite federal investments, the U.S. faces a $3.6 trillion infrastructure funding shortfall over the next decade.
The solution? Risk-based planning and preventive maintenance. By addressing issues early, governments can save up to 40% on costs, extend asset lifespans, and improve public safety. Investing now prevents emergencies later.
Financial Risks: How Delayed Maintenance Increases Costs
How Delayed Maintenance Multiplies Repair Costs
Putting off maintenance doesn’t just delay expenses – it skyrockets them. According to Oxmaint research, a repair initially costing $100,000 can grow to $197,000 in ten years, $386,000 in twenty years, and an eye-watering $762,000 in thirty years [2]. This happens because of what experts call "progressive deterioration." Once protective systems fail, damage spreads, compounding the problem and the expense.
Take a leaking roof as an example. Ignoring it might seem harmless at first, but that small issue can lead to water damage affecting HVAC systems, electrical panels, and structural components. What could have been a $5,000 roof repair turns into a $28,000 to $45,000 multi-system overhaul within just five years [2].
Real-world examples drive this point home. Between 2019 and 2023, a mid-sized county in the Western U.S. discovered they had a $41 million deferred maintenance backlog, more than double their initial estimate of $18 million. By adopting a computerized maintenance management system and shifting to preventive vs. reactive maintenance, they slashed emergency repair spending from 44% to 11% of their budget and saved $14.6 million over four years [2].
"Every budget cycle that defers a maintenance item is not a saving. It is a compounding investment in a future emergency." – Taylor, Oxmaint [2]
The same principle applies to road maintenance. Keeping pavement at a Pavement Condition Index (PCI) of 70 costs just $0.08 per square foot. But letting it degrade to a PCI of 40 increases rehabilitation costs to $0.55 per square foot – nearly seven times higher [2]. Once infrastructure crosses critical damage thresholds, costs can surge by 300–400% [2].
These ballooning costs don’t just strain budgets – they also weigh heavily on local economies and taxpayers.
Economic Effects on Communities and Taxpayers
The consequences of deferred maintenance ripple far beyond repair bills. Aging infrastructure hampers economic productivity and community well-being. For instance, traffic congestion caused by deteriorating roads costs the U.S. economy more than $200 billion annually in wasted time and fuel [1]. On a broader scale, poor infrastructure can shave off as much as 3% of GDP [1].
Deferred maintenance also triggers a phenomenon known as "capital displacement." When emergency repairs eat up funds, planned investments in new projects or upgrades get canceled or delayed. This creates a vicious cycle where governments struggle just to maintain the status quo, let alone improve or expand services [2]. Across the U.S., the deferred maintenance backlog for state and local governments has now reached an estimated $5.2 trillion [2].
Rising costs make the situation even worse. Since 2020, highway construction costs have jumped by 70%, while deferred maintenance grows at 7% per jaar. Combined with 4–6% material inflation, postponed projects can see costs climb by over 12% each year [3] [2].
Staffing shortages add yet another layer of expense. Research from Yale University shows that infrastructure projects managed by experienced in-house engineers cost roughly 14% less than those handled by external consultants [3]. However, as seasoned engineers retire or leave public service, agencies lose this cost-saving advantage. Even a 1% loss in experienced engineers can raise project costs by 4.3% [3].
"When it comes to the skilled engineers managing large infrastructure projects, the civil servant quantity and quality pay for themselves many times over… If any of those stages is implemented poorly by the government, costs can skyrocket." – Zach Liscow, Researcher, Yale University [3]
In contrast, organizations that prioritize preventive maintenance manage to keep cumulative costs within 0.8–1.2 times the original estimate and limit emergency spending to less than 8% of their budgets [2].

Operational and Safety Risks of Aging Assets
Higher Failure Rates and Service Disruptions
Old infrastructure doesn’t just cost more to maintain – it breaks down more frequently. A study revealed that 65% of infrastructure failures between 2025 and 2026 were tied to assets operating past their intended lifespan [8]. These systems weren’t just aging; they were being pushed far beyond their original capacity.
The impact is widespread and disruptive. In 2025, over 2 million U.S. residents experienced water system failures [8], while power grid disruptions led to $150 billion in economic losses [8]. Across the Atlantic, the UK faces daily water losses of 3 billion liters due to leaks in aging pipes dating back to the Victorian era [1][5]. These failures highlight the strain on outdated systems.
What’s worse, deferred maintenance often turns isolated failures into cascading disasters. Electrical systems, HVAC units, and structural components that rely on each other can break down simultaneously, creating a "capital cliff" – a scenario where multiple costly failures hit at once [6].
"Continued operation is no longer a reliable indicator that capital risk is contained. It masked deterioration." – Environment+Energy Leader [6]
The operational breakdowns that result from aging infrastructure inevitably lead to serious public safety risks and increased liability.
Public Safety and Liability Risks
The human toll of neglected infrastructure is staggering. Take the I-35W bridge collapse in Minneapolis in 2007: it killed 13 people and injured 145 others [10]. Fast forward to 2021, when a critical crack was discovered on a six-lane bridge over the Mississippi River. The bridge was closed for three months, disrupting interstate shipping. Shockingly, the crack had been visible in drone footage taken two years earlier but had gone unnoticed by inspectors [11].
Dams pose an even greater danger. Nearly 17,000 U.S. dams are labeled high-hazard potential, meaning failure could lead to loss of life [9]. The numbers are alarming: dam failures and emergency interventions jumped from 3 per year between 1994 and 2003 to 76 per year between 2014 and 2023 [9]. One example is the Edenville Dam failure in Michigan in May 2020. After heavy rain, the dam breached, overtopping the Sanford Dam and forcing 11,000 residents to evacuate. The disaster damaged over 2,500 structures and caused $200 million in economic losses [9].
Aging infrastructure also threatens public health. Lead leaches into drinking water from old pipes, and failing sewer systems overflow during storms, releasing untreated waste into neighborhoods. Hazardous waste sites are equally vulnerable. During Hurricane Harvey in 2017, floodwaters breached earthen containers at the San Jacinto River Waste Pits in Texas, spilling toxic waste into the river system [10].
"If you have a leak in your roof, you go up there, find it, replace the shingles, put on a little tar. If you let it go, it’s not going to be a little fix: it’s going to be a replacement." – Maria Lehman, President, ASCE [10]
The burden of these failures falls hardest on low-income communities. These areas often face longer recovery times and harsher economic consequences [8]. While wealthier neighborhoods may have alternatives when a water main breaks or a bridge closes, poorer communities are left with limited or no options at all.
Risk-Based Investment Planning: A Preventive Approach
Using Predictive Models to Plan Maintenance
Predictive models are transforming how infrastructure is managed, shifting the focus from reactive fixes to proactive solutions. By using a risk score – which considers the probability and consequences of failure – these models help prioritize funding for assets before issues escalate. Instead of waiting for a bridge to crack or a water main to burst, these tools pinpoint the ideal time for intervention, often when an asset is still in "Fair" condition. This timing prevents costs from climbing exponentially as deterioration worsens [12].
Neem Oxand Simeo™ as an example. This platform leverages aging models and maintenance laws to simulate how components deteriorate over time. By integrating data from inspections, condition assessments, and asset records, it predicts failures early – well before they hit the steep cost curve of advanced deterioration.
Four key dimensions guide funding decisions: safety and liability, cascade damage velocity, cumulative cost increases, and service criticality [2]. For instance, fixing a roof leak might take precedence over addressing a cosmetic issue because water damage can cascade, affecting HVAC units and electrical systems below. The financial impact of such damage can grow by 12–18% annually [2]. This approach not only identifies urgent needs but also delivers measurable savings.
A great example comes from a mid-sized Western U.S. County that tackled a $41 million deferred maintenance backlog across 87 facilities between 2019 and 2023. By using a CMMS (Computerized Maintenance Management System) for preventive planning, the county reduced its backlog to $31 million. They justified projects like a $2.4 million HVAC replacement for a courthouse using cost modeling, showing how deferring the replacement would lead to $5.1 million in combined repair and replacement costs within five years. This shift also cut emergency repair spending from 44% to 11% of the budget, saving $14.6 million [2].
"When we showed that deferring the $2.4 million courthouse HVAC replacement another five years would cost $3.9 million in 2028 dollars plus $1.2 million in cumulative repair costs to keep it running, the calculation changed."
– Facilities Director, Office of Public Works, Western U.S. County [2]
Voordelen van risicogebaseerde planning
Quantifying risks makes the financial case for preventive maintenance hard to ignore. For every $1 spent on preventive maintenance, agencies avoid $4 to $8 in future corrective repair costs. Additionally, condition-based strategies can save about 40% in capital expenses compared to traditional age-based replacements [2] [4] [12]. This approach ensures assets are used to their full potential while avoiding the 3–5× cost multiplier tied to emergency repairs [12].
When managed through a CMMS, preventive programs extend asset lifespans to 90–110% of their design life, compared to just 55–70% for assets in deferred maintenance scenarios [2]. This longevity reduces the frequency of replacements and minimizes costly disruptions. Planned maintenance also smooths out budgets, replacing unpredictable emergency expenses with predictable spending cycles.
In one city of 120,000 residents, the Director of Engineering used condition assessment data to reprioritize a $4.2 million streetscape project in favor of a $3.1 million water main replacement. The data revealed a 73% failure probability for the pipes within 24 months. By acting quickly, the city avoided catastrophic pipe failures during a freeze event just three months later, achieving a 3.4× ROI within the first year [12].
"Condition assessment tells you what to fix, risk assessment tells you what to fix first."
– Taylor, Oxmaint [12]
Risk-based planning also addresses a critical issue: niet-lineaire kapitaalkoppeling, where neglecting one system forces costly, synchronized repairs across multiple connected systems [4]. By identifying these interdependencies early, agencies can plan coordinated renewals, cutting costs and avoiding emergencies. This approach ensures public safety while promoting long-term financial stability.
Aligning Infrastructure Investments with Carbon Reduction Goals
Combining Energy and CO₂ Reduction with Asset Planning
Infrastructure is responsible for a staggering 80% of global greenhouse gas emissions, encompassing both operational emissions and the carbon embedded in materials [13]. This means that every decision about maintaining infrastructure carries climate implications. When agencies plan asset renewals, they face a critical choice: replace aging systems with similar components or seize the opportunity to upgrade to low-carbon, high-efficiency alternatives.
The interconnected nature of infrastructure systems often presents a chance to incorporate carbon reduction measures during renewals. Take, for example, an HVAC system at the end of its lifecycle. Replacing it often necessitates updates to electrical systems and safety controls [4]. This interdependency creates an ideal moment to align multiple systems with carbon reduction goals in one coordinated effort. Instead of treating energy retrofits as standalone projects, agencies can integrate them into scheduled renewals, cutting down on duplicate mobilization costs and minimizing downtime.
Voorspellend onderhoud plays a key role in this process by pinpointing the best time for intervention. It helps avoid emergency repairs while also extending the life of assets. Predictive models not only forecast maintenance needs but also guide transitions to low-carbon alternatives. Tools like Oxand Simeo™ simulate how components age and consume energy over time, enabling agencies to evaluate various renewal scenarios. While high-efficiency replacements might require a larger upfront investment, the long-term energy savings and lower carbon emissions often deliver a strong return on investment. Additionally, addressing koolstofuitstoot – which makes up 18% of infrastructure CO₂ emissions – by prioritizing low-carbon materials during renewals can further reduce environmental impact [13][14]. This integrated approach ensures that asset renewals align with both financial and environmental goals.
Measuring the ROI of Carbon-Aligned Investments
Proactively planning for low-carbon upgrades not only supports sustainability goals but also makes financial sense. For every $1 of deferred maintenance, future renewal costs can rise by an estimated $4 [4]. Add in indirect costs like emergency procurement, downtime, and increased insurance premiums, and that multiplier can exceed 10x [4]. Acting ahead of time helps agencies sidestep these escalating costs while simultaneously lowering energy use and emissions.
One major factor to consider is infrastructure readiness. For example, building-level upgrades, such as electrification retrofits, often follow shorter timelines, while improvements to the underlying grid or water infrastructure can take years [15]. This timing mismatch can lead to "stranded capability", where newly installed high-efficiency systems can’t operate at full capacity due to delays in supporting infrastructure. To avoid this, agencies should test decarbonization projects against various capacity scenarios and confirm utility readiness before committing funds [15].
"Asset-level returns often assume system capacity that does not yet exist – forcing organizations to absorb delays and risk at the building level rather than where the constraint actually sits."
– Boston Consulting Group [15]
This issue also has financial implications. Moody’s Ratings has started linking infrastructure reliability and upgrade timelines to credit outlooks, acknowledging that capacity uncertainties can pose long-term risks to cash flow [15]. By coordinating building-level improvements with grid readiness and leveraging predictive models to sequence upgrades, agencies can achieve cost savings, reduce emissions, and enhance financial stability. This approach not only supports environmental goals but also strengthens the fiscal foundation for future projects.
Deferred Maintenance Is Becoming a Capital Risk
Reactive Maintenance vs. Risk-Based Planning: A Comparison
Reactive vs Risk-Based Infrastructure Maintenance: Cost and Performance Comparison
Key Metrics for Comparison
Proactive maintenance offers clear advantages, and comparing key metrics reveals how reactive maintenance falls short when measured against risk-based planning.
The contrast between these approaches isn’t just theoretical – it directly impacts budgets and operational efficiency. Reactive maintenance often leads to what experts call "nonlinear capital coupling" – a domino effect where the failure of one aging system necessitates immediate, unplanned repairs in related systems to maintain safety and compliance [17].
Delaying maintenance has a steep price. For every $1 of maintenance deferred, future capital renewal costs can increase by $4 – and when indirect costs are factored in, this multiplier can exceed ten times [17]. Federal data paints a stark picture: deferred maintenance liabilities ballooned by 1,900% over three decades, climbing from $4 billion in 1991 to $80 billion by FY22 [16]. On the other hand, proactive detection and intervention can cut maintenance costs by up to 40% [16].
"For every dollar of maintenance deferred, future capital renewal costs increase by an estimated four dollars. When indirect costs are included… the multiplier can exceed tenfold."
– Marybeth Collins [17]
Operational differences are just as striking. Reactive maintenance consumes 45% of technician time on emergency responses, compared to less than 17% under risk-based planning [18]. Unplanned downtime can cost over $25,000 per hour [18], and emergency repairs are typically 3 to 5 times more expensive dan gepland preventief onderhoud [18]. Risk-based planning replaces guesswork with objective scoring systems that prioritize safety, asset importance, and the costs of delays [18]. These metrics highlight why adopting risk-based strategies is essential for effective capital management.
| Metrisch | Reactief onderhoud | Op risico gebaseerde planning |
|---|---|---|
| Relative Cost | 4x to 10x higher than proactive intervention [16][17] | Up to 40% reduction in total maintenance costs [16] |
| Emergency Work Orders | ~45% of technician time [18] | <17% (best practice target) [18] |
| Levensduur van activa | Shortened by cascading failures [17] | Extended through early repairs [7] |
| Downtime Cost | $25,000+ per hour (unplanned) [18] | Minimized with scheduled maintenance [18] |
| Data Usage | Reactive to visible failures [7] | Continuous AI-driven monitoring [7] |
The switch from reactive to risk-based planning isn’t just about avoiding emergencies – it’s about taking control of capital allocation. As Marybeth Collins aptly noted:
"The risk is not surprise failure. The risk is forced capital movement with diminishing choice."
– Marybeth Collins [17]
This comparison underscores the importance of moving toward proactive, risk-based strategies to reduce hidden costs and build more resilient infrastructure.
Conclusion: Planning for Resilient Infrastructure
Postponing maintenance isn’t a cost-saving measure – it’s a financial burden that grows exponentially over time. For instance, delaying a $100,000 repair today could balloon into a $762,000 expense in just 30 years [2]. Across the U.S., the backlog of deferred maintenance for state and local governments has reached a staggering $5.2 trillion [2], with federal assets adding over $370 billion in deferred obligations as of fiscal year 2024 [17]. Clearly, reactive maintenance strategies are no longer sustainable.
A smarter approach involves risicogebaseerde planning, which transforms massive deferred maintenance challenges into manageable tasks. This method works by quantifying the impact of delays, identifying interconnected risks, and prioritizing repairs based on safety concerns and potential cascading damage [2]. Time and again, preventive maintenance has proven to be a cost-effective strategy, saving significant future expenses [2][17].
"The 7% compound rate is not a law of nature – it is the consequence of maintenance deferral, and it stops the moment preventive investment begins." – Oxmaint [2]

FAQs
How do agencies decide what to fix first?
Agencies handle repair priorities through well-organized processes that weigh urgency, safety concerns, and the potential impact on operations. Tools like AI-powered scoring systems help rank repairs by analyzing factors such as safety risks and the importance of specific assets. By using data-driven techniques – like predictive analytics and condition assessments – agencies can zero in on the most pressing repairs. This forward-thinking approach not only minimizes safety hazards and operational downtime but also helps manage costs effectively while working within tight budgets.
What data do you need to start risk-based maintenance?
To kick off risk-based maintenance, you’ll need a solid foundation of detailed data about your assets’ condition and performance. This means gathering information like inspection results (think structural assessments, material conditions, and safety compliance) to pinpoint potential weak spots. Historical maintenance records are also key – they help you understand lifecycle patterns and spot trends over time.
But that’s not all. You’ll also want to factor in data about asset usage, environmental conditionsen operational stresses. These details play a big role in predicting how long an asset will last and determining which areas need attention first. When your data is thorough and dependable, you can allocate resources more effectively and steer clear of expensive breakdowns.
How can upgrades cut both costs and CO2?
Upgrading older infrastructure offers a double benefit: cutting costs and lowering CO2 emissions. By improving efficiency and extending the life of assets, these updates can significantly reduce expenses over time. Using modern materials and implementing predictive maintenance helps avoid expensive failures and minimizes the need for emergency repairs.
Energy-efficient systems play a key role as well, decreasing power consumption and reducing greenhouse gas emissions. This aligns with broader environmental goals. Investing in sustainable technologies not only creates resilient and cost-effective systems but also ensures consistent service quality while shrinking the overall carbon footprint.
