Where civil contractors lose money
5 things cost civil contractors money without ever showing up as a line item, and each one traces to a step you can install. Civil contractors average 21% gross margin, 14% overhead and 7% net profit at $1M–$5M of revenue. The CFOS target at that size is 23% gross margin, 13% overhead and 10% net, and the gap of 3 points on the bottom line is where those mechanisms live. Figures for all 7 revenue bands are in the table below.
Civil sits 2nd of 11 in civil and earthwork on net profit, and it carries leaner overhead than the 48-trade average. Here is every figure, across all 7 revenue bands.

5 problems specific to civil
You bid 40,000 yards of import and every scale ticket comes back in tons. You clear and grub in month one, come back for wet utilities, come back again for paving subgrade at closeout, and the contract still carries one mobilization line. You finished grading in month three and utilities in month six, and the last 5 to 10 percent of your contract sits behind a seed bed that has to hit 70 percent cover. Third resubmittal on the grading permit, the power pole relocation is six months out, and your crew and iron carry cost while nobody in your contract chain is at fault.
Each one below points at the item, the unit, the clock, or the party that makes it a civil problem, and it says which step fixes it.
| Mechanism | Why it's specific to this trade | Step |
|---|---|---|
| You bid cubic yards and pay by the ton | Most trades buy and install the same unit, so a box of material is a box of material all the way through. Civil buys tons at the pit, hauls by the hour or the load, and gets paid by the cubic yard at plan measure, which means three different units describe one pile of dirt. The conversion lives in the estimator's head and never on the ticket, so the error widens with nobody watching it. | Estimating system |
| Four mobilizations, one mob line item | Civil is the one scope that has to fully leave a site it will be back on four more times, because the pad, the wet utilities, and the paving subgrade happen months apart with other trades in between. Everybody else stages material and keeps a crew close. You're freighting a dozer, an excavator, and a roller down the highway each time, and the return trip has to be pulled out of whatever job that iron is sitting on now. | Job cost structure |
| Your retainage is waiting on 70 percent grass | A trade sub's retention is released when the punch list closes. Yours is released when a plant grows. Civil is the only scope whose final payment is gated on a biological clock and a permit filing that belongs to the site owner, months or years after the last blade left the property. | Project management |
| The grading permit clock isn't on your schedule | A submittal to an architect has a contract behind it and a GC who can push on it. A plan reviewer and a power company work order queue have neither, and civil is the only scope that can't turn a wheel until both of them clear. Every other trade's delay clock doesn't even start until you're already in the ground. | Project management |
| Trench dips appear inside the bond window | Most trades see their defects surface during the punch walk while somebody is still standing on the job. Civil's are buried, latent, and seasonal: the trench and the pond don't fail until a wet season works on them, long after closeout and long after the cost codes closed. The proof sits in a stack of third-party density tests taken months before anyone knew there would be an argument. | Standards and accountability |

Proof from this trade
What owners ask
What overhead should a civil contractor run?
Civil shares its overhead figure with 10 other trades at this revenue, which is what the published data resolves to. It runs 14% at $1M–$5M and 8% at $500M+, as a percentage of revenue. That sits 1 point below the civil and earthwork average of 15%. The CFOS target at $1M–$5M is 13%. The CFOS target is one point leaner than your trade's average at your revenue.
What gross margin should a civil contractor run?
Civil shares its gross margin figure with 5 other trades at this revenue, which is what the published data resolves to. It runs 21% at $1M–$5M and 30% at $500M+, as a percentage of revenue. That sits 0.3 points above the civil and earthwork average of 20.7%. The CFOS target at $1M–$5M is 23%. The CFOS target is published at $1M to $5M. It's set at whatever gross margin produces the net profit target once overhead is paid, and never below your trade's own average.
What net profit should a civil contractor run?
Civil shares its net profit figure with 16 other trades at this revenue, which is what the published data resolves to. It runs 7% at $1M–$5M and 22% at $500M+, before taxes, as a percentage of revenue. That sits 1.3 points above the civil and earthwork average of 5.7%. The CFOS target at $1M–$5M is 10%. The CFOS target is published at $1M to $5M.
What profit margin should a small civil business run?
Owners usually mean net profit when they say profit margin, and for civil at $1M–$5M that's 7%. Gross margin is a different number, 21%, and it's what's left after job costs but before overhead. Overhead is the 14% sitting between the two. A small civil business holding 7% net is at the published figure for its size, and the CFOS target at that revenue is 10%.
Does civil get more profitable as it grows?
Overhead is the number that moves. Civil sheds 6 points between $1M–$5M and $500M+, which is in line with the 6.2 points civil and earthwork sheds as a group. Net profit starts 0 points under the 48-trade average, so the room is in the overhead line before it's anywhere else.
Where does civil sit against the other trades?
Civil ties 4 trades in civil and earthwork on net profit, all at 7%. SWPPP and erosion control keeps the most at 10%. Its overhead is the leanest too, level with Excavation, Paving, SWPPP and erosion control. Gross margin ranks 33rd of 48 and overhead ranks 6th.
