CIVIL & EARTHWORK CLUSTER · CFOS TRADE OPERATING SYSTEM

WHY SITEWORK CONTRACTORS LOSE MARGIN WITHOUT KNOWING IT.

QUICK ANSWER

Sitework margin is lost to three specific things: the lender's leash, the package blur, and the sequence tax. Sitework subcontractors at $1M to $5M run 18 percent gross and 5.5 percent net, against CFOS targets at $1M to $5M of 24 percent gross and 10 percent net. All three are measurable, and all three are invisible without job costing that reads against the estimate.

Sitework contractors at $1M to $5M net 5.5 percent, rising to 8.5 percent by $25M to $50M; 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. Developer-direct contracts pay on construction-loan draw schedules, not on production. When the draw stalls, the receivable stalls, and the sitework contractor with iron on site finances the gap. Developer credit review and draw visibility belong in the bid decision.

THE THREE BIG LEAKS

THE MATH BEHIND THE MISSING CASH.

LEAK 01

The Lender's Leash

Developer-direct contracts pay on construction-loan draw schedules, not on production. When the draw stalls, the receivable stalls, and the sitework contractor with iron on site finances the gap. Developer credit review and draw visibility belong in the bid decision.

LEAK 02

The Package Blur

Multi-scope contracts hide quantity variance and invite boundary drift; every undocumented "while you're out there" is production without paper. The directive log and phase-weighted billing are how a package stays a contract instead of a favor.

LEAK 03

The Sequence Tax

Every utility crew and inspector passing through the site can idle the spread, and standby that's not coded and documented is margin donated to someone else's delay. (cfos-job-profitability-system) ---

HOW CFOS FIXES IT

WHAT CHANGES IN THE FIRST 60 DAYS.

The developer's calendar (slow pay at the top of the food chain)
Scope creep in the package (the "while you're out there" trade)
Cut/fill quantity variance (the estimate vs the survey)
Phase billing across a package
Utility coordination cost (the other trades in your dirt)

Industry figures are Sitework 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.

Sitework contractors at $1M to $5M 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. The gap concentrates in three sitework-native leaks: developer draw delays, package scope creep, and standby time nobody coded. Every net profit figure here is stated before taxes, the same basis CFMA reports on, so the two are directly comparable.
Because developer money is usually lender money: draws disburse on the construction loan's schedule and inspection gates, not on your production. Check the developer's funding before bidding, get draw-schedule visibility in the contract, and calendar lien deadlines against loan milestones, not invoice dates.
Same-day field directives: every "while you're out there" request gets a signed T&M ticket or a priced change order before the machine moves. A package contract makes drift easy to ask for and hard to bill later; the directive log is the boundary.
Phase-weighted, not flat percent-complete. Clearing and mass grading concentrate the iron and trucking cost early; utilities and paving prep spend differently. Weight the schedule of values to each phase's real cost curve so the billing follows the spend.
Track customer-level margin after the cash costs: days-to-pay, retainage drag, change-order approval rate, and standby caused. Two customers with identical contract margins can be a 4-point spread apart once the cash behavior is priced in.
A bookkeeper records history. Developer credit review, phase-weighted billing, directive logs, and standby cost codes are a control system, which is CFO work. SPM operates that financial control function for sitework contractors. ---
CFOS serves commercial sitework 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.
