What does unstable soil typically indicate on a construction site?

1. Ideal conditions for building

2. Potential hazards and increased risks during construction

3. Low water table levels

4. High soil density

The correct answer is: Potential hazards and increased risks during construction

Unstable soil on a construction site typically indicates potential hazards and increased risks during construction. When soil is unstable, it may not have the necessary bearing capacity to support structures, which can lead to issues such as settling or shifting. Additionally, unstable soil can increase the risk of landslides, erosion, or other geological hazards, complicating the construction process and potentially jeopardizing the safety of the workers and the integrity of the project. This recognition of risks is crucial for proper planning and implementing necessary engineering solutions to ensure safety and structural stability. The other options do not accurately describe the implications of unstable soil. Ideal conditions for building would suggest a stable and well-compacted soil structure, while low water table levels and high soil density typically indicate more favorable conditions for construction rather than instability.
