Soil Investigation or geotechnical investigation is a process that defines the stratigraphy and appropriate physical properties of the soil underlying the site. This is done to ensure that this substructure, which is ultimately going to hold up homes, is safe and lasting.
To determine the bearing capacity of the soil, soil investigation must be undertaken, its settlement rate, and the position of the water table. With minimum disturbance are collected for subsequent laboratory testing, one of the easiest methods is to dig trial pits and visual inspections carried out then samples, Drilling should be undertaken Wherever it is possible as this enables one to obtain undisturbed samples from which settlement rate and bearing capacity may be obtained.
It is of primary importance that a proper field survey and a very precise geotechnical investigation be conducted, for any civil engineering project, however big or small. To obtain information about the physical characteristics of soil/rock around a site, the geotechnical investigation is an integral part of the construction process which is done. To establish its characteristics, it is a below-ground investigation wherein the soil strata are sampled and tested, which will influence the construction project.
How precise the information in the geotechnical report is effective affects the design, construction, project cost, and safety.
Unfortunately, during the conceptual phase of a project, many people underestimate the importance of the proper geotechnical investigation. One of the best causes of foundation collapse is inadequate knowledge of ground conditions.
To save on such site investigations have led to disastrous results, there have been some instances were attempting. Because structures that are designed on assumed or inadequate data can lead to long-term complications. For the intended purpose, it may also result in loss of life and property, endanger residents, damage adjoining structures, and essentially be rendered non-functional.
Thus, at the site of an engineering project, soil investigations provide the engineer with knowledge of the subsurface conditions. He will encounter in the field as it allows the engineer to work out the safe and economical design of a project and inform the construction engineer about the material and conditions.
Conclusion: Soil investigation companies can make testing on the soil and can identify the bearing capacity of the soil. The basic need for this analysis is to get an idea about the land after all it holds up homes that should be safe and enduring.
