Step by step

  1. List sections Separate strip footings, pads and steps.
  2. Measure dimensions Use the designed concrete dimensions.
  3. Calculate volumes Multiply length × width × depth for each section.
  4. Add together Convert the total to cubic yards and review ordering allowance.

Formula or rule of thumb

planning quantity = measured project area or volume × project-specific factor

Example

Use the measured project dimensions, apply the product or layout assumptions, then round to the package or supplier unit.

Common mistakes

Do not hide waste, package coverage, product yield or site assumptions inside one unexplained number.

Planning note: product yields, installation methods, site conditions and local requirements can change the final quantity. Use the exact manufacturer or supplier information before purchasing.
