29 AUGUST 2022 WorldWide Drilling Resource® CPT and Risk Mitigation Adapted from Information by Vertek Cone penetration testing, or CPT, is an advanced in situ test which uses a steel cone equipped with sensors to record and relay real-time measurements of multiple data points such as resistance, friction, and pore water pressure. CPT is a valuable site investigation tool for risk mitigation. By understanding the characteristics of the soil and subsurface materials, CPT can help find potential risks in the design and building of infrastructure. It can also be used to assess the vulnerability of sites to natural hazards. CPT and Risk Mitigation - Risk mitigation can be defined as actions to prevent or reduce adverse outcomes of hazards. Therefore, risk mitigation minimizes the probability and impact of threats and reduces the amount of financial loss. There are many ways to mitigate risks, especially when constructing buildings and infrastructure. One of these methods is CPT. CPT should be an essential part of a well-planned risk mitigation strategy because it provides on-site data to identify potential problems before they become an issue. In this sense, CPT mitigates a portion of the subsurface risk because structures can be designed to appropriately respond to the soil conditions, reducing factors of safety used in design and construction activities. Benefits of CPT and Risk Mitigation - CPT is an advanced geotechnical testing method providing detailed information about the soil. Unlike standard penetration tests (SPT), CPT has the advantage of being less invasive than SPT while also being significantly more accurate. Only a small hole (less than 2 inches) is created by the cone penetrometer, and data is measured and displayed in real-time as it advances into the soil. CPT can identify how the soil composition responds to seismic waves from earthquakes, vibrations from running machinery, and other factors. The response to these generated seismic waves is often used to determine soil liquefaction potential, providing pertinent engineering information in structure design for super-structures like buildings and bridges. Geotechnical and structural engineers consider many factors such as: slope stability, liquefaction potential, soil settlement, and soil shearing derived from CPT analysis. Without a CPT test, structures may not be built to suit the conditions under the ground’s surface or mischaracterized, leaving it vulnerable to damage under the right conditions. Utilizing Risk Mitigation & Soil Testing - Since CPT testing is both quick and efficient, the process delivers accurate results in less time than SPT and other methods. In addition, the process itself is also safer, which reduces risk in the testing process as well. The data collected with CPT allows engineers to quickly adapt to soil conditions to ensure the project design is suitable. Without this, they could be taking on considerable risks. Unstable soil is the last thing a business would want to respond to amid a project underway. When combined with other risk management techniques, CPT provides a safe and efficient method of obtaining a comprehensive picture of a site’s risk to help make informed decisions about risk reduction measures. If you are looking to expand the services your drilling company offers, consider adding CPT testing. At the 2021 NDAConvention, Jesse Mastine explained just how easy it is to add CPT services with a Drill Rig Conversion Kit which can be used on virtually any drill rig with a static push/pull hydraulic mast.
