There are so many students who don’t always know what civil engineering discipline to choose when applying for college, and then, when it becomes time to take their FE Exams, they battle even more as they might have chosen a discipline that does not fit their interests or personality. Therefore, we thought it would be helpful to start a series on each of the 5 civil engineering disciplines to give you a better idea what to expect both in your studies, and FE exams. We will discuss the roles and responsibilities of each one of these disciplines and the skills needed for each discipline, to help you in your decision making process, and in this article (and video above), we will take a look at The Geotechnical Engineering Discipline.
What Do Geotechnical Engineers Do?
Geotechnical engineering is a branch of civil engineering; however, it involves using scientific methods and principles to collect and interpret the physical properties of the ground. Geotechnical engineers are involved in all stages of the design of structures, from concept to construction. Their work is essential in the design and planning process as they assess the integrity of soil, clay, silt, sand, and rock, prior to construction commencing. They start by undertaking a desk (or in office) study, assessing maps, and contacting local authorities. This is followed by a ground (or field) investigation based on the findings of the desk study and involves trial pitting and sampling to uncover any potential issues.
Geotechnical engineers work within multidisciplinary teams, supported by intermediate and junior engineers as well as by CAD technicians. As a senior geotechnical engineer on a hydro plant project, tasks may include participating in technical reviews (e.g., peer reviews), tailings dam inspections, dam safety reviews, and other studies related to the design and construction of mine waste facilities.
Why Is a Geotechnical Engineer So Important?
The role of a geotechnical engineer is so important because they are responsible for evaluating the ground conditions of a site prior to build-out or construction. Ground conditions can vary greatly even on a small site, and with added challenges such as climate change impacting the environment with droughts and floods, the role of a geotechnical engineer is becoming even more significant. They must determine whether the ground can withstand the added pressures or changes brought by construction, which can ultimately avoid costly issues further into the project.
What Does It Take To Be a Geotechnical Engineer?
To be a geotechnical engineer, you will need a degree in geotechnical engineering, geological engineering, geo-environmental engineering, or a related field. Depending on your level of entry, you may need experience in design work, for example on dikes and dams. It is also beneficial to have some knowledge of slope stability, flow, and stress-strain software such as GeoStudio, FLAC or Plaxis.
As previously mentioned, geotechnical engineers work in teams, so it is essential to have good communication and team-building skills to effectively work with various stakeholders, including clients. It’s also important to be innovative in this discipline, building a greener future for the growing population and factoring in other major social, economic, and environmental factors that will be a catalyst for change.
Geotechnical engineering is a mix of engineering and science, and geotechnical engineers may work in construction determining whether the land is safe to build or they may work with other scientists in tracking climate change. These engineers are very important, especially when it comes to the overall success of construction projects. They ensure there is no possibility of unsafe ground being built on, preventing homes and buildings from being built upon soil that could cause a landslide, avalanche, or other damage.
A critical skill needed for this job is math because geotechnical engineers need to analyze data and be able to study the geology of a specific area. A bachelor’s degree in civil engineering or in another engineering field is required in order to be considered for this job. Most geotechnical engineers will also go beyond their degree and seek Professional Engineering licensure. They must also have expert knowledge in CAD software, as well as Microsoft Office Suite.
Here Are a Few of the Responsibilities You Can Expect to Have:
- Observing and documenting field activities related to the construction process
- Sampling, testing, and inspecting soils, aggregates, concrete, grout, masonry, asphalt, and structural steel placement
- Performing calculations and data reduction of test results along with drafting
- Using field testing equipment and documenting readings
- Reading maps, following directions, and interpreting engineering and construction plans
- Interacting and communicating daily with contractors, technicians, and project manager
- Testing of soils, foundations, reinforced and post-tensioned concrete masonry, structural steel, and asphalt pavement
- Determining and/or performing appropriate laboratory tests
- Attending project meetings and assisting in project resolutions
- Assisting with the preparation of proposals
- Assisting with scheduling, training, and oversight of Field Technicians
- Assist with managing project budgets, project set-ups, and invoicing
