Use Case
Quantifying the Deferred Maintenance Backlog
Turn a growing deferred maintenance backlog into a defensible, risk-ranked plan that shows leadership the cost of waiting — and which dollars retire the most risk.
Quick answer. A deferred maintenance backlog is the accumulated cost of repair and renewal work an agency has postponed past its ideal timing. To quantify it credibly, an agency measures asset condition against a state-of-good-repair target, forecasts deterioration, and risk-ranks the gap. InfraMind turns that condition data into a prioritized, budget-tested capital plan and a defensible cost-of-waiting number for leadership.
What the deferred maintenance backlog is — and why a number alone isn't enough
The deferred maintenance backlog is the total cost of the repair, preservation, and renewal work an agency has put off beyond the point where it would have been most cost-effective to do it. Most agencies can name a backlog number; far fewer can defend it. A credible backlog is tied to measured condition and a documented state-of-good-repair target, risk-ranked so leadership knows which work matters most, and paired with the cost of continued deferral. Without that structure, a backlog figure is easy to challenge and easy to ignore.
The national backdrop
The deferred maintenance problem is national in scale. The figures below frame why quantifying your backlog — and prioritizing within it — is now a core capital planning task.

How to quantify and prioritize the backlog
Quantifying a deferred maintenance backlog is the process of turning asset condition into a defensible dollar figure, then ranking the work inside it by risk. InfraMind, the owner-side planning layer on top of your EAM and GIS, runs that process end to end:
1. Inventory and condition
Pull a complete, cross-asset inventory with current condition from your EAM and GIS — the denominator the backlog is measured against.
2. Define the target
Set a state-of-good-repair target condition so the backlog is the gap between where assets are and where they should be, not a vague wish list.
3. Forecast deterioration
Project how condition declines so you can quantify how fast the backlog grows — and the cost of deferring each treatment another year.
4. Risk-rank the work
Score projects by probability and consequence of failure so the backlog is prioritized, not just totaled.
5. Plan against the budget
Run funding scenarios to show which slice of the backlog each budget level actually retires — and what it leaves behind.
6. Show the cost of waiting
Give leadership a defensible number for what deferral costs in future dollars and risk, not just the headline backlog figure.
The risk-ranked backlog is the raw material for a defensible capital plan. See how to prioritize infrastructure projects when the budget won't cover everything and how to build a defensible capital improvement plan.
Why the cost of waiting is the number that moves budgets
The cost of waiting is what deferral adds to the eventual bill — the difference between a timely preservation treatment and the reconstruction that becomes necessary once an asset is allowed to fail. Because deterioration accelerates as condition drops, a dollar of preservation today routinely prevents several dollars of reconstruction later. Quantifying that curve for your network turns the backlog from a static liability into an argument for funding the right work now. The same logic underpins grant and funding readiness and the GASB 34 modified approach.
