Data on Unscheduled Downtime
Unscheduled Downtime Revenue Impact
Concrete • Aggregate / Crushing • Asphalt
A practical benchmark for estimating gross production revenue exposed when an industrial materials facility experiences an unplanned shutdown.
What the Metric Means
Gross production revenue at risk = normal production volume that cannot be produced during the shutdown × representative selling price.
Disclosure: this metric is a production-value benchmark, not a claim that every dollar becomes permanently lost revenue.
· Excluded from the headline figures: idle labor, trucking/hauling disruption, restart and troubleshooting time, overtime, rejected or spoiled material, downstream crew delays, missed delivery windows, contractual impacts, and customer schedule disruption.
· Actual financial exposure varies by product mix, local pricing, plant utilization, shift length, inventory buffers, ability to make up production later, and whether downstream operations are also interrupted.
· For sales and maintenance discussions, use “gross production revenue at risk” rather than “lost profit” or guaranteed “lost revenue.
Aggregate / Crushing Revenue Exposure
Aggregate operations vary widely in throughput. The table below uses the 2026 YTD Vulcan freight-adjusted aggregate selling price of $22.89/ton and an 8-hour production day for the hourly benchmark. The 3–5-day column models downtime while obtaining parts and completing repairs, from experience when a failure occurs there are three to five full production days interrupted waiting on parts.
Practical Uptime Message
Four hours matters. At representative production rates, four hours of unplanned downtime can place approximately $94,000 of ready-mix production, $17,000 of aggregate production, or $127,000 of asphalt production revenue at risk.
That makes preventive electrical maintenance, critical-spares planning, controls troubleshooting, condition monitoring, and rapid emergency response easier to evaluate against the economic exposure of a shutdown.
