In excavation terms, what is a trench?

A trench is accurately defined as a narrow excavation made by digging. This definition highlights the characteristic width and depth of a trench compared to other types of excavations. Trenches are typically used in construction and utility projects to install or access pipelines, conduits, or cables. They can also be created for foundations, drainage, or other engineering purposes.

The emphasis on being "narrow" differentiates a trench from broader excavations such as pits or holes. Furthermore, the act of digging implies that a trench is formed through skilled manual or mechanical labor, which is vital in excavation contexts. The proper recognition of a trench's purpose and physical attributes is essential for safety and regulatory compliance in excavation work.
