What must a competent person evaluate after classifying a soil deposit?

A competent person must evaluate changes in properties affecting the classification after classifying a soil deposit to ensure safety and stability. Soil classification is based on criteria such as soil type, moisture content, and structure. Once the soil is classified, it is essential to monitor for changes that can impact its properties, such as saturation from rain, freezing and thawing cycles, or disturbance from excavation activities. These factors can alter the soil's behavior, increasing the risk of collapse or instability during excavation work, which is critical for the safety of workers and the integrity of the project.

While the location, color, and climate conditions can be relevant in assessing a soil deposit, they do not directly address immediate factors that may change the soil's characteristics after classification. The primary focus should always be on the physical properties of the soil that may influence its classification and behavior during excavation tasks.
