UNDERGROUND UTILITY JOBS LOOK PROFITABLE. THE ACCOUNT IS STILL EMPTY.
Underground Utility subcontractors run out of cash for reasons specific to how the work is built and billed, on jobs that are making money. The three that cost the most in this trade are below, taken from underground utility contractor research. Most sit at 75 to 90 days from finishing work to holding the money, and 45 days is achievable.
Cash and profit are measured on different clocks. Your profit and loss records revenue when you invoice and costs when you incur them, while the bank account only knows what cleared. Labour goes out weekly and collects 45 to 90 days later, minus retention. That distance is what a growing, profitable underground utility company funds out of pocket, and it widens as you grow. The specific things that widen it in this trade are what the rest of this page is about.
WHERE IT LEAKS OUT.
Bore pits, casing, and drill setup concentrate cost before the first foot of product pipe bills. Enrichment: keep pit excavation, shoring, and dewatering coded separately from bore production so the unit price and the setup cost stop hiding each other.
City and district owners pay on council-approval and warrant cycles. Prompt-pay statutes help only when invoices are undisputed and deadlines are calendared.
Same 811/strict-liability regime, GL sublimits, and fine tiers the excavation file documents, sharpened by linear exposure: a pipeline crew crosses more foreign utilities per week than a mass-ex crew does per job, and vacuum excavation is the control.
WHAT MOVES MARGIN IN THIS TRADE.
The Two Bores
HDD and open cut are separate production economies sold under one bid book; blended histories misprice both, and an 18 percent gross margin can't fund systematic mispricing in either direction.
The Linear Gauntlet
Every week of pipe crosses more foreign utilities than most trades meet in a year, under strict-liability locate law with GL sublimits underneath. Potholing and vacuum excavation are financial controls priced into the work, not optional caution.
The Council's Calendar
Municipal owners pay on approval cycles, hold retainage to restoration acceptance, and replace lien rights with bond claims. The public-owner cash carry gets priced in the bid or funded by the contractor. (cfos-cash-control-system) ---
DAYS SALES OUTSTANDING.
Ninety days is weak, 45 is the target, 30 is strong. Nothing else moves cash faster.
| Position | Days | What it means |
|---|---|---|
| Weak | 90 days | Roughly three months of work funded out of your own pocket. |
| Target | 45 days | Achievable on the days you control: submission timing, complete documentation, follow up in week two. |
| Strong | 30 days | Requires discipline every month, and it's the cheapest capital available to you. |
Moving from 90 days to 45 frees roughly annual revenue divided by 365, times 45 days. At $4M that's about $493,000. At $8M it's about $986,000. That money doesn't come from a bank and it costs no interest, which is why we work the cycle before discussing financing anything.
UNDERGROUND UTILITY BENCHMARKS.
Underground Utility subcontractors at $1M to $5M net 3 percent, against a CFOS target of 10 percent, set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher. Working capital should sit at 13 percent of annual revenue, and the monthly close should finish by day 10 so the numbers can still change a decision.
