Sitework subcontractors manage broad scope operations where net profit is influenced by self-perform percentage, trade coordination overhead, and the environmental compliance costs that come with multi-scope site development work.
Net profit margin is what's left after every expense is paid — direct job costs, field labor, materials, overhead, and all G&A. It's the true bottom line. These benchmarks reflect what well-managed sitework contractors actually generate at each revenue level.
How to calculate your net profit margin: Net profit (after all expenses including owner salary at market rate) divided by total revenue for the trailing 12 months. Owner salary should reflect what you'd pay someone else to do your job — not a distribution. Compare that number to the benchmark for your revenue band below.
Trade note for Sitework Contractors: Sitework net profit margin is directly affected by the self-perform vs. subcontract decision. Sitework contractors who self-perform 80%+ of their scope carry higher overhead (equipment, supervision) but typically generate 1–3% better net margin than contractors who subcontract most of their scope — because self-perform retains the margin that would otherwise go to subcontractors.
SWPPP compliance, stormwater management, and environmental permit coordination create overhead that straight sitework operations don't carry. Contractors who don't price this overhead explicitly are subsidizing environmental compliance out of net margin on every environmentally complex site.
When the self-perform percentage of work changes — moving from 70% to 50% self-perform — revenue may stay constant while overhead stays the same. Net margin compresses because overhead isn't adjusting to match the reduced self-perform volume.
Sitework scope creep — additional clearing, changed grades, unexpected utilities — is extremely common. Contractors who document and bill scope changes systematically show 2–4% better net margin than those who absorb scope changes in the field.
SPM tracks net margin separately by sitework scope type — clearing, grading, utilities, paving — in ControlQore for clients with multi-scope operations. Scope-level net margin analysis reveals which portions of the sitework business are generating returns and which are subsidizing the others.
When Executive clients are evaluating changes to their self-perform vs. subcontract mix, SPM models the net margin impact of the change before it's made — showing whether the margin improvement from the changed scope mix justifies any overhead adjustment required.
SWPPP documentation, environmental coordination, and compliance reporting costs are tracked as a dedicated overhead category in ControlQore for sitework clients. This visibility supports accurate bid pricing on environmentally complex sites and reveals the true cost of maintaining compliance capability.
