What does groundwater level significantly affect in construction projects?

Groundwater level significantly affects soil bearing capacity in construction projects because it influences the weight that the soil can support. When groundwater levels rise, soil can become saturated, which reduces its strength and stability. This change can lead to a decrease in the load-bearing capacity of the soil, making it more susceptible to issues such as settling or shifting.

Understanding the groundwater conditions is crucial for engineers and contractors when assessing whether the soil will adequately support the proposed structures. If the soil bearing capacity is compromised due to high groundwater levels, additional measures may need to be implemented, such as dewatering, using deep foundations, or selecting alternative construction methods to ensure safety and structural integrity. This makes the assessment of soil bearing capacity a key factor in planning and executing construction projects.
