Estimating limitation
These calculators are estimating tools for planning and field checks. They are not a substitute for approved plans, specifications, licensed professional engineering, or governing standards. Confirm densities, waste factors, and yields with your supplier and project documents.
What PlanQty is not
PlanQty is not a licensed engineering firm and does not replace a licensed engineer, inspector, or superintendent. Results are not a design, a specification, or an approval.
Project-specific factors
Density, waste, shrink/swell, and production factors vary by mix, soil, and crew. Change the defaults when the job documents give different values. Calculator pages also repeat this limitation next to the formula.
