What unit is used to measure lift thickness in this construction context?

Explanation:
Lift thickness refers to the depth of a single layer you place and then compact. That depth needs precise control in the field, so inches are used. Using inches lets you measure small, exact amounts (like 1/2 inch or 1 inch) and match the tolerances that grading and compaction specify. Feet would be too coarse, and meters or yards are not practical for the fine adjustments typically required in a single lift. In many projects you’ll see lifts described in loose thickness (before compaction) of a few inches to achieve the desired compacted thickness, reinforcing why inches are the standard unit here.
