What is referred to as the 'face of the trench'?

The 'face of the trench' specifically refers to the vertical wall that is exposed in the trench. This terminology is commonly used in excavation and construction contexts, where the face constitutes the area that is visible and accessible after digging has taken place. Understanding this term is crucial for ensuring safety measures are in place, as the stability of the trench walls can affect the overall integrity and safety of the excavation work. Recognizing the significance of the face helps in assessing risks such as potential collapses, which is essential when planning for shoring or sloping the walls during operations.
