In dirty work, what does the term "lift" refer to?

In the context of dirt work and excavation, the term "lift" specifically refers to any layer of soil that is placed on top of another layer of soil. This concept is critical in various construction and earthwork operations, particularly when considering the compaction and stabilization of soil layers.

When soil is excavated, it is often necessary to place it back in layers (or lifts) to ensure that each layer is adequately compacted. Each lift can be thoroughly compacted before the next layer is added on top, which helps to create a stable foundation and minimizes future settling.

This method is essential for achieving the desired soil density and strength, contributing to the overall integrity of the structure being built. Understanding the concept of lifts is crucial for general contractors and construction professionals as it relates to best practices in earthmoving and site preparation.
