A Few Facts About Subsurface Investigation

By Kathleen Hughes


Before building plans can be approved, various things need to be done. Although you might leave all this work to your architects and contractors, you need to know the basics of at least each procedure. However, one that you should properly understand is subsurface investigation. Once you know what this procedure is about, you will see its relevance.

The procedure itself is simple the examination of that lies below the surface, mainly soil rocks and water. The way the tests are conducted will depend on the experts you hire, but mainly they will all focus on the same things. When soil and water are tested, the main aim is to know the chemical structure of these components and also to check to for contaminants.

To be thorough, some people will also evaluate how the area would fair in the event of seismic activity. Mainly for this, they will look at the soil, rocks and the records. This way, you will know in advance whether it is safe to do any construction in the area, and what measures you should take to safeguard whatever structure you establish.

This process is typically done in two stages. The first will involve engineers taking samples from the land. This is done using borers or by digging pits, to allow for the in site observation of the soil profile and ground water levels. After this, some of these samples will be taken back to a laboratory for testing. Here, they will observe the chemical composition of the soil and also tests to see whether any pollutants have contaminated it.

You cannot just hire any investigator for this job. They should be well trained and certified. This way, you are guaranteed that they know how to handle the equipment and also to interpret the results. Various firms and individuals offer these services. By talking to your contractor, you can quickly determine which one will be the best fit for your project.

Specialized machines will also be required for this work, and your professional should have this. Proper tools will warrant accurate results and also quick work. If you hire someone who has the know-how but no tools, you might have to do the running around trying to get them the equipment required.

Construction works need to be approved by the relevant government agencies, and this also applies to this testing. Therefore, while your building plans are being evaluated, you can start applying for the subsurface test permit. This way, there will be no delays affecting your time line. The firm of experts you hire should be the ones handling this responsibility, but you can also choose to do the application yourself.

Many people view this process as a waste of money but overlooking it can be dangerous. You might end up putting up a building on fault lines and in the event of an earthquake even a small one the whole construction could come down. Additionally, you may let pipes run through contaminated soil and over time, these pollutants might find a way into your water, leading to diseases or even the loss of lives.
