If you’ve ever marvelled at towering skyscrapers, intricate bridges, or massive dams, you might be fascinated by geotechnical engineering!
Geotechnical engineers play a crucial role in ensuring the stability and safety of structures by understanding the interface between what you see above ground and what lies beneath. This understanding the properties of soil and rock, and natural hazards such as earthquakes..
Join us and our employer partner, Tonkin+Taylor, as we explore what geotechnical engineers do, the qualification pathways to becoming one, and the essential skills for success in this field.
What Does a Geotechnical Engineer Do?
Geotechnical engineers are like the silent heroes of the construction world.
They specialise in understanding the behaviour of soil, rock, and the impact of natural hazards to make informed decisions about the engineering design and construction of the built environment.
Here’s a look at some of the key responsibilities and tasks that geotechnical engineers handle:
Site Investigations:
- Conducting geotechnical site investigations to develop an understanding of the subsurface conditions at a site to inform engineering decisions.
- Collecting samples of soil and/or rock to perform laboratory tests to analyse the engineering properties to inform design.
Seismic Assessment (Earthquakes):
- Understanding the seismic hazard that may exist at a site so that it can be accounted for during engineering design.
- Designing ground improvements to mitigate the potential effects of earthquakes (e.g., liquefaction) to protect foundations and structures.
Slope Stability Assessment:
- Understanding landforms and the susceptibility to landslides based on topography and underlying soil conditions.
- Assessing the stability of slopes and embankments to mitigate the impact of landslides and erosion.
- Designing solutions to reinforce or stabilise slopes when necessary.
Foundation Design:
- Designing foundations for buildings, bridges, and other structures to ensure they are stable and can withstand the loads they will bear.
- Recommending foundation types such as shallow foundations or deep foundations (e.g., piles) based on the structure and the underlying soil conditions.
Retaining Structures:
- Designing retaining walls and retention structures to support ground and the structures founded within.
- Calculating the necessary reinforcements and materials that comprise the structures.
Construction Monitoring:
- Monitoring construction projects to ensure that geotechnical recommendations and design are being implemented correctly by the constructor.
- Providing advice when soil-related issues arise during construction.
Environmental Impact Assessment:
- Evaluating the environmental impact of construction activities on soil and groundwater.
- Developing strategies to minimise negative effects and protect the environment.
What Are the Qualification Pathways to Becoming a Geotechnical Engineer?
Becoming a geotechnical engineer involves a combination of education, licensure, and practical experience. Here’s a typical pathway to pursue this career:
- Bachelor’s Degree in Civil or Geotechnical Engineering: Start by earning a bachelor’s degree in civil engineering or geotechnical engineering from an accredited university. This program typically takes four years and covers fundamental engineering principles, mathematics, and specialised geotechnical courses.
- Internships and Entry-Level Positions: Gain hands-on experience through internships, traineeships or entry-level positions in engineering firms or geotechnical laboratories. This practical experience is invaluable in understanding the real-world applications of geotechnical engineering.
- Postgraduate Education (Optional): Pursuing a master’s or doctoral degree in geotechnical engineering can provide advanced knowledge and research opportunities. While it’s typically not required, it can open doors to specialised roles and higher positions in the field.
- Licensure: Seek Chartered Professional Engineer (CPEng) status through Engineering New Zealand, the country’s professional engineering body. This certification involves demonstrating your competence and expertise in your chosen engineering field.
- Continuing Education: Geotechnical engineering is dynamic, and ongoing professional development is essential. Many engineers pursue certifications and attend workshops or courses to stay up-to-date with industry trends and technologies.
How to Start Gaining Work Experience
Gaining work experience is a crucial step towards becoming a successful engineer. Almost every engineering degree in New Zealand contains an industry placement component, a great way to develop your skills.
Other opportunities to build your experience include:
- Internships, Traineeships & Cadetships: Look for internships, traineeships and cadetships offered by engineering firms or government agencies. These opportunities allow you to apply your classroom knowledge in real-world settings.
- Networking: Attend industry events, join professional organisations like Engineering New Zealand and the Technical Societies such as the New Zealand Geotechnical Society, to connect with experienced engineers. Networking can help you discover work experience and mentors who can guide your career.
- Entry-Level Positions: Consider starting in entry-level positions, such as junior engineers or engineering technicians. These roles provide hands-on experience and opportunities for growth.
- Volunteer Work: Participate in volunteer projects related to civil engineering through organisations like Engineers Without Borders. This can demonstrate your commitment to the field and allow you to work on meaningful projects even before you land a paid position.
Top Skills Geotechnical Engineers Should Have
You’ll need a diverse skill set to excel as a geotechnical engineer. Some of these you can develop through a wide range of activities, and many you’ll start to get through your studies.
Here are some of the top skills every geotechnical engineer should develop:
- Geotechnical Analysis: Proficiency in soil and rock testing techniques and interpretation, and using geotechnical software for analysis and design.
- Attention to Detail: Precision in data collection, analysis, and design to ensure the safety and stability of structures.
- Communication: The ability to present technical information in a clear and understandable manner and communicate well with colleagues, clients, and stakeholders.
- Environmental Awareness: Understanding sustainability principles and environmental impact assessment and designing projects with minimal ecological footprint.
- Adaptability: The capacity to adapt to evolving technologies and industry trends and stay updated throughout your career.
