Geotechnical drilling is often related to the development of a structure such as an oil rig or bridge. This is conducted on site before a structure is built, as part of the site investigation process. This is typically executed by geotechnical engineering firms, under the supervision of a geotechnical expert who ensures drilling meets the needs of the project.
Since geotechnical drilling is mainly to investigate constructions site, data gathered from drilling rock and soil sample testing determines the safety and suitability of a construction for that particular area. The site study is crucial for large structures. Soil or rock uncertain conditions can lead to collapse, or may create a hazard in an earthquake or flood. Sites must be thoroughly checked and tested for safety according to the law before permission to build is issued, and that continuous monitoring of security is done to detect any changes or signs of developmental problems that may pose a threat to development.
In the process of construction, geotechnical drilling involves drilling in preparation for the foundations, and supports various drawers. The drilling of this type is supervised by a professional engineer confirming the location of the hole and ensures that the drilling is successful. Drilling a hole in the wrong place can cause problems which may lead to countless delays.
Geotech drilling is mainly of used in a two-part processes: Firstly, it about performing a site investigation for any planned structure, before it was ever built, and second, as part of the construction process, including prepping for foundations, caissons, and various supports. A geotechnical engineer would typically oversee that these processes are executed reliably to ensure a safe and successful construction output.
Geotech Drilling for Site Investigations.
Site investigations are critical for large structures. Unsafe soil or rock conditions may lead to structural collapse, or could create threat to an unexpected detailed site investigation 
earthquake or flood. The purpose of having a geotech drilling on site investigations is to be able to gather soil samples, and soil sample data that would analyze the suitability and safety of a structure in that particular area. The law would often require site investigations before issuing any permit to a contractor. This principle should reduce any posing threat to human health and environment.
Geotech Drilling during Construction Process.
Obviously, to get the required depth used to install foundations in any structure, a contractor would require geotech drilling. Other projects, such as, building an oil rig, geotechnical explorations, and mining would all need drilling. Drilling is used to take core samples and to gather information about the site. It is also used by scientists to learn more about the Earth, for example, taking out sample from ice cores, these samples reveals fascinating record of the Earth’s climate history!
Geotech drilling is required in most geotechnical engineering and civil engineering projects. This entails expertise and proper equipment to become successful, safe, reliable, and even cost-effective.
