What lies beneath a building can be just as important as what you see above ground.
Two sites that look almost identical on the surface can have completely different soil and groundwater conditions.
What Is Site Investigation?
Site investigation involves examining the physical and engineering characteristics of a proposed construction site.
Depending on the project, this may involve:
- Site reconnaissance
- Topographical surveys
- Soil investigation
- Trial pits
- Boreholes
- Laboratory testing
- Groundwater assessment
Why Is It Important?
Proper investigation helps professionals understand the conditions they are designing for. It can help identify:
- Weak or compressible soils that may require special consideration.
- Groundwater conditions that can affect excavation and foundations.
- Variations in soil layers across the site.
- Potential drainage or stability issues.
The Cost of Getting It Wrong
Inadequate site investigation can contribute to inappropriate foundation decisions, excessive settlement, cracking and other structural or construction problems.
The cost of investigation is therefore not simply another project expense. It is an investment in informed design and construction.
