What is the typical percentage of lumber wasted during framing?

When considering lumber waste during framing, the commonly accepted figure is around 10%. This percentage accounts for various factors that lead to waste in construction, including cutting errors, unusable pieces due to defects, and adjustments made during construction processes to accommodate unique site conditions or design changes.

In typical framing projects, measurements can be off, or pieces can be damaged during handling or transport, contributing to waste. Planned waste, which is factored into the budget and material ordering processes, also plays a role. Understanding this percentage is essential for contractors as it helps in estimating costs and determining the amount of lumber to purchase for a project, thereby minimizing financial loss while ensuring adequate materials are available for construction.

The other options present higher percentages of waste that are generally not observed in standard framing practices, making 10% the most realistic estimation for planning purposes.
