Why is sampling conducted in the field?

Sampling in the field is primarily conducted to obtain samples of materials present on the site. This process is crucial for understanding the current condition and characteristics of the materials, such as soil, rock, or aggregate, which are essential for planning and executing earthwork projects. Gathering physical samples allows professionals to evaluate aspects like compaction, moisture content, and pollutants that may be present, ensuring that the materials can be used effectively and safely in construction or remediation efforts.

Securing samples directly from the site provides valuable insights that are not only important for immediate project needs but also assist in making informed decisions regarding design, equipment, and methods to be used in the project. This approach enhances the credibility and reliability of the data collected, which is fundamental for project success.
