Managing Risk on Geotechnical Projects Through Quality Laboratory Testing Programs – Ep 032

In this episode, we talk to Anna M. Kotas, P.E., a technical sales and business development professional at GeoTesting Express (GTX), about how engineers can manage risk on geotechnical projects using quality laboratory testing programs. Engineering Quotes: Here Are Some of the Questions We Ask Anna: Why is good quality laboratory testing data important, and how can it affect the quality of a geotechnical design? What are some of the consequences of conducting poor or insufficient laboratory testing programs? What are the factors that may contribute to the occurrence of an error during laboratory testing? When laboratory testing parameters are misunderstood, how could they affect engineering projects? How can geotechnical testing help engineers to minimize risk on geotechnical engineering projects? What final piece of advice would you like to give the listeners today? Here Are Some of the Key Points Discussed About Managing Risk on Geotechnical Projects Through Quality Laboratory Testing Programs: Good quality laboratory testing data starts with obtaining a good quality sample. A laboratory testing result is only as good as the sample you bring in for testing. You must have a well-thought-out sampling process and good sampling techniques before you go out to the field. The sampling process should consist of the preservation of the sample, its moisture, its orientation, and how to transport it to the laboratory. Delivering a sample that is as close to the original conditions as possible is the goal of the sampling process. Good quality laboratory testing equipment and trained individuals performing the testing are vital to getting accurate results. The individuals must have good knowledge of soil mechanics and the process of testing the samples. The entire process must be done quickly because it is a critical part of the designing process. Conducting poor or using insufficient laboratory testing programs will have its consequences. Having poor results will lead to having poor designs that cause the costs and the risks of the project to be higher. Poor understanding of laboratory testing programs is a big problem. Companies must allow their staff to learn about in-depth laboratory testing programs and how important they can be for a project. It will give them a better understanding of the values that will help them produce correct values for the projects. Incorrectly calibrated testing equipment will influence the test results. Human error plays a significant role in laboratory error. It includes having under-skilled people conducting the tests, errors in data entry, and calculation errors. Using more automated equipment can help reduce the human error factor in laboratory testing programs. Sample quality plays a significant role in the results when using automated equipment. Geotechnical engineering already has many risks when it comes to the unknown factors of the project sites, and everyone wants someone to be held accountable for any errors which arise. The associated risks of geotechnical engineering can be even higher than constructing the projects. Quality laboratory testing programs reduce the unknown factor risks by providing tangible and accurate information to be applied in your geotechnical designs. Always question and understand your data. Ask if you need more clarity, practice, or experience so that you can fully harness and use the data in your design.
