Soil investigations involve the following steps
1) Planning the details and sequence of operations
2) Collection of soil samples from the field
3) Conducting all field tests for determining the strength and compressibility characteristics of the soil
4) Study of ground water level conditions and collection of water samples for chemical analysis
5) Geophysical exploration if necessary
6) Testing in the laboratory of all samples of soil, rock, and water
7) Preparation of drawings and charts
8) Analysis of the results of the tests
