Site investigations are essential because they provide critical information about the subsurface conditions of a site, ensuring safe, efficient, and cost-effective construction. Key reasons to use site investigations include:

​

1. Risk Mitigation: Identifies potential hazards like unstable soil, water issues, or contamination early, preventing costly problems during construction.

2. Foundation Design: Provides data for designing strong, stable foundations tailored to the ground conditions, avoiding structural failures.

3. Environmental Safety: Detects contaminants or hazards, ensuring compliance with regulations and protecting public health.

4. Cost Efficiency: Prevents unexpected expenses by uncovering issues before construction begins, leading to better project planning and budgeting.

5. Legal Compliance: Ensures the project adheres to local, national, and environmental regulations, avoiding delays or legal issues.

 

Overall, site investigations are critical for informed decision-making, reducing risks, and ensuring a project's success.
