UNDERGROUND UTILITY JOBS LOOK PROFITABLE. THE ACCOUNT IS STILL EMPTY.
Underground Utility subcontractors have no cash left 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 are 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 put cost in before the first foot of product pipe bills. Code pit excavation, shoring and dewatering separately from bore production, so you can see the unit price and the setup cost on their own.
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 rules, GL sublimits and fine tiers as excavation, made worse by linear exposure. A pipeline crew crosses more foreign utilities per week than a mass-ex crew does per job. Vacuum excavation is the control.
WHAT MOVES MARGIN IN THIS TRADE.
The Two Bores
HDD and open cut are two different production businesses sold out of one bid book. A blended history misprices both. An 18 percent gross margin can't pay for mispricing either one job after job.
The Linear Gauntlet
Every week your pipe crosses more foreign utilities than most trades see in a year. Locate law is strict liability, and your GL policy has sublimits. Potholing and vacuum excavation are financial controls, and you price them into the work.
The Council's Calendar
Municipal owners pay on approval cycles, hold retainage until restoration acceptance and give you bond claims in place of lien rights. You either price the public-owner cash lag into the bid or pay for it yourself.
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 | You can get here on the days you control. Bill on time, send complete paperwork, and follow up in week two. |
| Strong | 30 days | Takes work every month. It's the cheapest money you can get. |
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 costs no interest and needs no bank. So we fix billing and collections before we talk about financing.
UNDERGROUND UTILITY BENCHMARKS.
Underground Utility subcontractors at $1M to $5M net 3 percent, against the CFOS net profit target, set at your trade's net profit average at your revenue plus 3.5 points, never below 10 percent, before taxes. The working capital target is 13 percent of annual revenue, and the monthly close should finish by day 10 so the numbers can still change a decision.
