• Conduct site reconnaissance and geotechnical survey

• Drill boreholes or dig trial pits at strategic locations

• Collect disturbed and undisturbed soil samples

• Conduct Standard Penetration Tests (SPT) or Cone Penetration Tests (CPT)

• Record soil stratigraphy, groundwater table, and surface conditions

• Conduct field tests for shear strength, density, and permeability

• Transport samples to laboratory for further testing

• Analyze results for bearing capacity, settlement, and soil classification

• Interpret geotechnical data in relation to proposed structures

• Prepare comprehensive soil investigation report

Soil investigation provides essential information about subsurface conditions, enabling engineers to design safe and economical foundations. Soil properties, layer thickness, and groundwater levels significantly affect structural stability and settlement.

Field exploration involves boreholes, trial pits, and in-situ testing to collect representative samples. Laboratory analysis determines mechanical and physical properties such as strength, compressibility, and permeability.

The final report provides soil profiles, bearing capacity, and recommendations for suitable foundation types. Accurate soil investigation reduces risk, ensures compliance, and optimizes foundation design.
