Geotechnical investigations are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil earthworks and foundations for proposed structures and for repair of distress to earthworks and structures caused by subsurface conditions; this type of investigation is called a site investigation.
Geotechnical engineers and engineering geologists perform geotechnical investigations to obtain information on the physical properties of soil and rock underlying and adjacent to a site to design earthworks and foundations for proposed structures and for the repair of distress to earthworks and structures caused by subsurface conditions ...

The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft soils.
Engineering geologists provide geological and geotechnical recommendations, analysis, and design associated with human development and various types of structures. [2] The realm of the engineering geologist is essentially in the area of earth-structure interactions, or investigation of how the earth or earth processes impact human made ...
The test provides samples for identification purposes and provides a measure of penetration resistance which can be used for geotechnical design purposes. Various local and widely published international correlations that relate blow count, or N-value, to the engineering properties of soils are available for geotechnical engineering purposes.
Total sounding (TS) is a sounding method performed as part of geotechnical investigation. The sounding combines conventional rotary-pressure sounding with bedrock drilling, including rotation, ramming and flushing modes. The result indicates sediment stratification, occasionally soil type and may verify depth to bedrock. [1]
Geotechnical surveys involve a combination of sampling, drilling, in situ testing as well as laboratory soil testing that is conducted offshore and, with samples, onshore. They serve to ground truth the results of the geophysical investigations; they also provide a detailed account of the seabed stratigraphy and soil engineering properties. [23]
