GRADING CONTRACTOR CASH FLOW PROBLEMS — THREE STRUCTURAL CAUSES.
Grading cash flow is not tight because grading work is unprofitable. It is tight because of three structural features of grading operations: large equipment costs that mobilize before billing starts, seasonal winter shutdown that stops revenue while overhead continues, and import fill and export haul cost spikes that require significant temporary working capital. Understanding which of these is driving the current cash problem determines the fix.
The grading contractors who manage cash well are not the ones who have better luck or better GC relationships. They are the ones who modeled the cash requirement before mobilizing, built the winter reserve in August, and structured the SOV so mobilization costs are recovered in the first billing cycle. The rest discover the problems when they are already unavoidable.
WHAT MAKES GRADING CASH FLOW SPECIFICALLY TIGHT.
Large Equipment Costs Hit Before Billing Starts
Grading work begins with equipment mobilization, site setup, and initial earthwork — all of which generate significant cost before the first billing cut-off. Mobilizing a dozer, scraper, grader, and compactor to a site costs $6,000–$14,000 in trucking alone. Operating those machines for the first two weeks before the first pay app generates $40,000–$80,000 in equipment operating cost and labor. The first check does not arrive until 30–60 days after the first pay app submission. On a $600K grading contract, the first-payment gap requires $80,000–$140,000 in working capital before any revenue returns.
Winter Shutdown Stops Revenue But Not Overhead
Grading work in most U.S. markets slows dramatically or stops entirely for 8–16 weeks in winter. Frozen ground, snow cover, and wet conditions make production grading impossible. Revenue drops toward zero. Overhead does not. A grading contractor doing $4M annually with 14% overhead carries $46,666 per month in fixed overhead costs through winter while billing $50,000–$100,000 — a gap of $20,000–$40,000 per month that comes out of the cash reserve or LOC. Over a 12-week winter, that is $60,000–$120,000 in cash consumed by overhead against reduced revenue.
Import Fill and Export Haul Create Concentrated Cash Outflows
Grading projects with significant earthwork create large, concentrated trucking and material costs during the earthwork phase. A week of heavy haul trucking can run $30,000–$50,000 in trucking cost alone. If the haul phase falls between billing cut-offs, those costs are funded for 30–60 days before the billing event covers them. On large import fill projects, the earthwork phase may require $80,000–$150,000 in temporary cash — all of which needs to be in the working capital model before the project mobilizes.
