Things To Note Concerning Subsurface Investigation

By Kenneth Murray


The construction industry has in the recent past, mushroomed all across the world. Many construction projects are coming up by the day. When constructing, nonetheless, there are a number of activities that need to be undertaken in order to ensure the project becomes successful and also is durable. One of these activities is the subsurface investigation.

If the engineer is aiming at locating the subsurface features the geophysical methods is what he or she will use. He or she locates, maps and measures the different components in the soil to achieve the required results. Stipulating that all locations were simple then the sampling would have been easier but facts from just one place cannot be used to define the whole site henceforth, diverse examinations on the locality are required.

This geo technical investigation comprises both subsurface survey and surface analysis of a location. Yet, geophysical methods are used to obtain data about the location whereas subsurface analysis encompasses the random sampling of the soil and further laboratory tests done on the soil specimens recovered.

Surface survey can include different types of methods which are, the environmental plotting, the geophysical approaches stated earlier, and finally photogrammetry. However, most engineers prefer to stride around the place to observe the physical settings of the surface if at all its not complex or does not require further tests.

Density is a vital feature in the measurement or research of a site that is sub-surface investigating, therefore, the density of the soil or rocks is measured through microgravity. Disparities in the internal soil compactness may include adjacent changes in soil or rock thickness, faults, hidden canals and distended joints on the ground. This technique is consequently used to detect holes, hollows and cavities existing in the ground. It can be used to find structures that have been made by man such as mines and tunnels and cannot be identified easily using other methods.

The third and also equally important part of subsurface investigating basically involves organizing for a meet-up or meeting session with a competent architect who is overseeing the project, as well as other proficient structural engineers. On this account, this is entirely aimed at gaining adequate and clear information essentially on the specifics, requirements, and any other vital information regarding the foundation of particular project.

Besides that, it is also vital to organize for a meeting even with the owner of that project, as well as many other relevant professionals. This could also provide more insight especially on the foundation, in a bid to ascertain its actual condition, whether it is deep, shallow, and other suchlike details. These meetings will also elaborate on the condition of that soil, and other important aspects such as the nature and condition of structures nearby the proposed location of the project.

Conclusively, it is imperative to note that there are specific aspects to consider while carrying out subsurface exploration which are, the inclusive worth of the venture and the financial plan for the location examination. It is crucial to know the cost allocated for the surveys of the ground to be certain on the method to use. Constructability and legitimate repercussions should be prior during analyses, practical terms should also be considered to ensure that you are on the right track before carrying out these investigations.
