Why must soil densities during construction be measured?

Measuring soil densities during construction is essential because constructed densities can fluctuate based on the water content present in the soil. The water content influences the weight and compaction of the soil, making it critical to monitor these densities to ensure that the soil can support the intended loads once construction is completed. If the water content is too high, it can lead to lower densities, which may result in settlement or failure of the structure over time.

Understanding the relationship between soil density and moisture levels allows engineers and construction managers to optimize soil compaction techniques and select appropriate materials, thus maintaining the necessary strength and stability of foundations and other structures. This consideration ultimately contributes to the longevity and safety of the entire construction project.
