CIVIL & EARTHWORK CLUSTER · CFOS TRADE OPERATING SYSTEM

WHY CIVIL CONTRACTORS LOSE MARGIN WITHOUT KNOWING IT.

QUICK ANSWER

Civil margin is lost to three specific things: the mobilization gap, the retainage stack, and iron that bills nothing. Civil subcontractors at $1M to $5M run 21 percent gross and 5.5 percent net, against CFOS targets at $1M to $5M of 23 percent gross and 10 percent net. All three are measurable, and all three are invisible without job costing that reads against the estimate.

Civil subcontractors at $1M to $5M net 5.5 percent; the CFOS target at $1M to $5M is 10 percent. The distance between the trade average and the CFOS target isn't a pricing problem in this trade. It sits in the three mechanisms below, each of which moves margin without appearing as a failure on any single job. Civil work front-loads cash out. Fuel, bond premiums, moves, and payroll run 60 to 90 days before pay app 1 clears. On a $2M job that's $150K to $200K spent before the first dollar returns. Fix: mobilization on its own schedule-of-values line, billed on pay app 1.

THE THREE BIG LEAKS

THE MATH BEHIND THE MISSING CASH.

LEAK 01

The Mobilization Gap

Civil work front-loads cash out. Fuel, bond premiums, moves, and payroll run 60 to 90 days before pay app 1 clears. On a $2M job that's $150K to $200K spent before the first dollar returns. Fix: mobilization on its own schedule-of-values line, billed on pay app 1.

LEAK 02

The Retainage Stack

5 to 10 percent held on every job. At a 5.5 percent net margin, a 10 percent hold locks the entire job profit until release, and three concurrent jobs lock six figures while payroll runs weekly. Fix: retainage tracked as its own receivable class, releases calendared, working capital sized to carry it.

LEAK 03

Iron That Bills Nothing

Ownership cost runs parked or working. Roughly $200 per day for a CAT 330 sitting still, with industry idle rates near 30 percent. Bids built without an ownership rate give that money away. A $7.1M civil contractor recovered $779K in three months once equipment cost stopped being buried. (cfos-job-profitability-system) ---

Industry figures are Civil contractors' AVERAGE for each revenue band, not a floor. The CFOS net profit target is set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher, and the gross margin target is set at whatever gross margin produces that net profit once your overhead is paid, and never below your trade's own average. Gross minus overhead equals net on every column, so the rows tie out.

Range reflects the three tiers below. Which one you're in depends on how much of the work you want off your desk. No payroll. No hidden line items.

Core

You stop guessing.

You get the CFO work. Job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a meeting every month that ends in decisions rather than a report.

Your bookkeeper keeps doing the books.

Executive

You stop touching the books.

Everything in Core, and we run the bookkeeping and the controllership as well. Nobody in your office is answering coding questions or chasing a reconciliation at month end.

We do the books. No payroll.

Strategic

Every job shows its margin while it's still running.

Everything in Executive, plus the job costing and WIP platform set up, loaded with your cost codes, and managed for you every month. You never have to learn it.

We do the job costing.

COMMON QUESTIONS

FREQUENTLY ASKED.

Civil subcontractors at $1M to $5M in revenue net 5.5 percent on average, rising to 8.5 percent by $25M to $50M. The CFOS target at $1M to $5M is 10 percent, and it rises with revenue. The gap between average and target usually sits in three places: unbilled mobilization, buried equipment cost, and retainage carried without a plan. Every net profit figure here is stated before taxes, the same basis CFMA reports on, so the two are directly comparable.
Because civil work pays you last. You fund mobilization for 60 to 90 days, carry 5 to 10 percent retainage on every job, and make equipment payments whether the iron runs or sits. Profit on the income statement and cash in the bank are separated by those three loans you're making to everyone else.
Put mobilization on its own schedule-of-values line and bill it on the first pay application, before production billing starts. Demobilization goes on a separate line at closeout. Burying mobilization in unit prices forces you to fund startup out of pocket and recover it slowly across the whole job.
5 to 10 percent, held until substantial completion or later. Some states cap public-work retainage at 5 percent, and Texas requires amounts above 5 percent on public projects to sit in an interest-bearing account. Know your state before you bid, and price the carry into the job.
About 13 to 14 percent of revenue at that size, falling toward 11 percent as revenue grows. The published outside ranges run wider than most owners expect: Jones Maresca and Company's 2025 Performance Benchmarks put total indirect cost at 8 to 15 percent of revenue for construction as a whole, and CFMA's 2024 Construction Financial Benchmarker reports SG&A at 11.8 percent across all respondents. Neither figure is a civil number, and /construction-overhead-rates-by-trade carries the civil rate by revenue band. Overhead that goes unmeasured gets recovered by accident, and civil overhead hides in the shop, the yard, and the pickup fleet.
Build an hourly rate for every machine that includes depreciation, interest, insurance, and storage, then compare billed hours against that rate monthly. If the rate only covers fuel and maintenance, every idle day comes straight out of net profit. Idle rates in the industry average 30 percent.
Plan on 60 to 90 days from work performed to cash received once approval cycles run. Mobilization is often capped at 5 to 10 percent and released in stages as the contract earns. The jobs are good; the cash timing is the part that breaks companies.
A bookkeeper records what happened. This problem set (mobilization billing, retainage carry, equipment rates, WIP for bonding) is a control-system problem, which is CFO work. SPM operates that financial control function for civil contractors; the bookkeeping rides underneath it. ---
CFOS serves commercial civil subcontractors doing $1M to $12M. Pricing starts at $1,900 per month for companies under $1M and runs to $13,500 per month at the top published band. Onboarding takes 60 days.
Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Executive is where you stop touching the books, because we run the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still running, because the job costing and WIP platform is set up and managed for you. No payroll. No scope gaps.
