How would you approach a ground investigation for a building structure?

Ground investigations mainly includes determining the condition of the ground, … To determine Ground layer thicknesses and the mechanical properties of soil. To collect detailed information about soil and ground samples . To determine strength of soil at different layers by conducting field as well as laboratory tests on soil.

Some of the ground investigation which are done before building construction are :-
– Desk study/preliminary risk assessments
– Trial pitting and trenching
– Window sampling and dynamic probe testing
– Insitu testing
– Cable percussive boreholes

Here, I will give you three main stages of soil investigation. They are given below:

1. Preliminary Investigation
2. Detailed Investigation
3. Supplementary Investigation & Control

Thank You.

1. Trial Pits and Trenches
2. Window Sampling
3. Light Cable percussive boreholes
4. Rotary Boreholes
5. Sonic Drilling
