Every contractor knows utility strikes are expensive. Most assume the repair invoice is the number that matters. It isn’t, and the gap between what contractors expect to pay and what they actually pay is where projects, and sometimes companies, get into trouble.
The Scale of the Problem
US crews damage underground utilities an estimated 400,000 to 800,000 times per year — roughly one to two strikes every minute. According to the CGA’s DIRT Report, the CGA Index, which tracks year-over-year damage trends, rose from 94.0 in 2023 to 96.7 in 2024, signaling the industry is moving in the wrong direction. The total cost to the US economy is an estimated $30 billion annually.
What a Strike Actually Costs: Direct vs. Indirect
The direct costs are what most people think of: the repair crew, the materials, the emergency response. These are real. They are also, as the data shows, the smallest part of the bill.
Research examining utility strike incidents found that indirect and societal costs can be nearly 30 times greater than the direct cost of repairing the damaged facility.
Here’s what that looks like on a typical gas line strike:
| Cost Category | Example Amount |
|---|---|
| Direct: Physical repair | $3,000 |
| Direct: Emergency response | $10,000–$50,000 |
| Indirect: Crew idle time (6 people × $100/hr × 2 days) | $10,000 |
| Indirect: Schedule delay / liquidated damages | $5,000–$25,000/day |
| Indirect: Equipment standby | $3,000–$8,000/day |
| Indirect: Rework, acceleration premiums | $10,000–$50,000 |
| Indirect: Legal, claims, insurance | $5,000–$30,000 |
| TOTAL ESTIMATED IMPACT | $40,000–$150,000+ |
A $2,000 direct repair routinely generates $60,000 or more in total impact. It is a 30:1 indirect cost ratio documented in CGA DIRT reports.
The Costs Nobody Budgets For
With an average work stoppage of 8–12 weeks per strike, and an estimated crew cost of $100/hour including labor burden, work stoppages alone account for $185 million in annual construction industry losses.
The costs that most often go unaccounted:
- Crew idle time. The whole crew stops, not just the operator who hit the line. A six-person crew sitting idle at $100/hour costs nearly $5,000 per day before a single repair starts.
- Schedule compression. Lost days rarely disappear. They get made up through overtime, weekend shifts, or liquidated damages. One documented case in California resulted in a 159-day delay, a $1.26 million settlement, and a 62–73% productivity loss.
- Reputational damage. This one never appears on an invoice, but it affects the next bid.
The Prevention Math
Professional utility locating and verification delivers a documented 2,000%-3000% ROI — a $2,500 investment in pre-excavation verification prevents a single $75,000 gas strike. Industry data confirms $4.62 saved per $1 spent on prevention.
The case for investing in better documentation, real-time locate records, and AR-based awareness tools isn’t a technology argument. When a single strike can cost 10–20% of a small contractor’s annual profit, prevention isn’t overhead. It’s margin protection.
