There are more than one test to evaluate the bearing capacity and settlement of the foundation level like plate load test, consolidation test, shear strength parameters and compaction test that it will be depend also on type of soil then all those tests will be done with geotechnical investigation.
Today, the CPT is one of the most used and accepted soil methods for soil investigation worldwide.
Common tests to measure the strength and stiffness include the triaxial shear and unconfined compression test.
Surface exploration can include geologic mapping, geophysical methods, and photogrammetry
Geophysical exploration is also sometimes used. Geophysical techniques used for subsurface exploration include measurement of seismic waves (pressure, shear, and Rayleigh waves), surface-wave methods and/or downhole methods, and electromagnetic surveys (magnetometer, resistivity, and ground-penetrating radar).
In general, geotechnical engineers:
First of all, geology of the soil
