In reference to dirt work, what is meant by the term 'lift'?

• A. The difference in grade from one point to another
• B. A section of ground that needs to be filled
• C. A horizontal ledge used for controlling erosion
• D. Any layer of soil placed upon another soil layer

Answer: (D)

In dirt work, a lift refers to the layer of soil that is placed on top of an existing layer and compacted before adding the next layer. This is why it’s the best fit—the term specifically describes a deposited layer of material rather than a vertical grade change, a fill area, or a bench for erosion control. For example, when building up grade, you place you’ll spread and compact a defined thickness of material, called a lift, then repeat with the next lift until you reach the target level. The other options describe different concepts—grade difference is the vertical rise between points, a section to be filled is a fill area, and a horizontal ledge for erosion control is a bench—so they don’t capture the meaning of lift in earthmoving.
