Geotechnical studies – when required. Always, when we start thinking about a construction investment in a single-family house, many questions arise. One of them, which has been appearing more and more often for several years, concerns whether we need to carry out geotechnical research on our plot. It is worth considering when geotechnical surveys are required, who carries them out and where they are used.
When do we need to carry out geotechnical studies?
Geotechnical research, if we take this subject under the microscope purely theoretically, is mandatory, but only if the building is an investment intended for public use or when its dimensions significantly exceed standard single-family housing. Practice shows, however, that, as a rule, the commission that approves the commencement of construction recommends almost one hundred percent to carry out such a study. In the past, the regulations clearly stated that if the architect noted on the construction plans that there were no obstacles to erecting a given project on the building plot, that was enough. Currently, it is the committee that decides whether a study needs to be performed and, as mentioned, this is done in the overwhelming majority of investments.
Who performs the test?
We will not focus here on whether the study will be performed by a small or large company. However, it is good to know what permissions the person taking such measurements should have. Such a person must have a geotechnical education or be a geologist with additional geotechnical or engineering education in the field of construction. So, for example, a geologist, mining geologist or deposit geologist can conduct the study, provided that he has additional qualifications. However, conducting the research alone is not enough. After the examination, an opinion in the form of a report must be issued. The report is detailed and must include, for example, a map of the plot with marked drilling locations, etc.
Geotechnics is an important field, not only because of construction. It affects our lives every day, because it helps in the search for mineral resources , such as oil. Let’s also talk a bit about this, because it’s a very interesting topic.
Deposit geology and mineral geology in search of oil deposits
Oil is one of the most important raw materials on which our civilization is based. We should start giving up oil, but it is not such a simple topic, and certainly not in every country. Generally speaking, we are constantly looking for new deposits of this raw material and it is not possible to completely abandon it in a short time, even in highly developed countries.
Mining geology and deposit research allow for a more accurate assessment of where it is best to search for new black gold resources. The largest deposits have been discovered a long time ago and have either been exploited or their intensive exploitation is taking place. For this reason, geologists are constantly selecting new areas for possible exploration. Such analyzes are important because many of these potential sites are located in extremely difficult places, such as the Arctic, and even carrying out test drillings is extremely expensive, so the decision on such an expedition must be preceded by really reliable analyzes, which are of course performed by geologists, reservoir geologists and mining geologists.
Where are the largest oil deposits located?
The largest oil deposits are located primarily on the Arabian Peninsula. Countries such as Kuwait, Saudi Arabia, Dubai, Iraq and Iran are classically the largest oil producers in the world, but there are two more regions worth mentioning, i.e. Nigeria in Africa and Venezuela in South America. But are these the only large deposits of oil on our planet?
It is worth mentioning that oil deposits are found not only in the areas that we currently exploit. Many of these deposits, which we will talk about in a moment, were not known until recently, or were known, but not sufficiently so that the geology of the deposits was able to evaluate them. Until recently, mining was so difficult that it was basically unprofitable. It is enough to recall the international scuffles that concerned the Arctic, among other things, to realize that they are primarily concerned with who will have the right to the deposits that lie under its waters, and as for the deposits that are under their waters , one of the most important is, among others, crude oil. There is also a lot of speculation that oil deposits may occur in Antarctica, because this continent used to be located much further north, i.e. close to the equator, which suggests that there may have been conditions for oil and natural gas to develop there. Undoubtedly, if we want to use crude oil, we will still have to look for new deposits.
