CASH FLOW FOR GRADING SUBCONTRACTORS — WHY IT IS TIGHT.
Grading subcontractors run tight cash because costs hit immediately and payment arrives 62 days later. Mobilization, labor, material, and overhead all run from day one. The first check does not arrive until the first pay app clears — typically 62 days after mobilization. On a $500K grading contract that is $60,000–$120,000 in costs deployed before a dollar comes back.
The cash flow pattern in grading work is structural — it is built into how the work is sequenced, how billing cycles work, and how GCs process payments. Understanding the specific cash flow mechanics of grading subcontracting is the first step toward managing it instead of reacting to it.
WHAT MAKES GRADING CASH FLOW SPECIFICALLY TIGHT.
Large Equipment Mobilization Costs Are the First Cash Outflow
Grading projects begin with large equipment mobilization — dozers, scrapers, graders, compactors trucked to site at $1,500–3,500 per load. A grading contractor mobilizing four pieces of equipment spends $6,000—14,000 in trucking before the first pass is made. Site setup, erosion controls, and temporary access add to the mobilization cost. All of it hits before the first billing cut-off.
Import Fill and Export Haul Costs Spike During Earthwork Phase
Grading projects with significant import or export earthwork create large, concentrated material and trucking costs. 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 can require $80,000–$150,000 in temporary cash.
Weather and Soil Conditions Create Cost Without Billing Credit
Grading work stops in wet conditions that prevent compaction. Wet soil conditions may require drying time, additional compaction passes, or soil amendment before grade certification. Those additional costs are often not compensable under the original contract unless a changed conditions claim is submitted. Wet weather delays create crew standby cost and equipment idle time against no corresponding billing.
