1. Mathematics – Higher Level (HL)

Mathematics is at the core of civil engineering. From the designing of structures to mathematical calculations of load-carrying capacities, engineers rely fully on mathematical principles. Mathematics HL entails a deeper understanding of the concepts of calculus, algebra, and statistics much as it encompasses civil engineering well. In this course, you will be provided with problem-solving skills and abundant numerical fluency that will help you face the big challenges in the engineering field.

2. Physics – Higher Level (HL)

Physics is another core area civil engineers must be conversant with. Here, it is focused especially on mechanics, forces, and energy. These topics will certainly apply in the work of a civil engineer designing bridges, dams, and buildings. Physics HL provides students with an enormous amount of knowledge about the physical laws that dictate materials' behavior under any scenario. This knowledge in particular allows the study of stresses, strains, and the forces acting to either maintain or compromise structural integrity.

Civil engineers need to be thorough in understanding how forces work on structures and how other materials respond to such forces. The HL Physics course provides that solid understanding, preparing them to construct useful and safe structures.

3. Chemistry – Standard Level (SL)

Chemistry is not the same as mathematics and physics in civil engineering; nevertheless, it can still give some insight to the knowledge acquired, mainly based on materials science. Chemistry SL delves into chemical properties of materials, which is an important knowledge in understanding how different construction materials work after a specific period of time. The knowledge of corrosion, composition of concrete, and environmental impacts related to material interaction helps in the sustainability of civil engineering projects.

Civil engineers often need to choose the right materials for specific projects, and understanding their chemical properties is vital for ensuring structural durability and sustainability.

4. Geography – Higher Level (HL) or Standard Level (SL)

Civil engineering is not only about construction engineering; it’s more about construction and the world it’s built in. Geography does have useful information about how physical and human environments interrelate and more so when designing infrastructural facilities such as roads, bridges, or water systems. Geography enables civil engineers to examine physical characteristics of the environment that needs to be embraced, how the land will be used, and the sustainability issues that should be addressed when designing the structures for practical use.

Geography educates children the way engineering projects affect the environment and the globe therefore making development proper without harming the environment.

5. Design Technology – Standard Level (SL)

Design Technology SL allows a student to experience practice in design technology, product development, and the application of modern technology to engineering. For civil engineers, this course will provide understanding on how to evolve from concept into construction, how to prototype models, as well as the use of tools like CAD. All these skills are indispensable in actual field operations whereby engineers will have to draft blueprints, visualie designs, and bring ideas into life.

During the study of Design Technology, students gain some practical experience that supplements the theory imparted by other subjects, so they are well-equipped to apply a creative and innovative approach for solving engineering problems.

6. Environmental Systems and Societies – Standard Level (SL)

Civil engineers today carry the mandate of ensuring that whatever infrastructure and projects are constructed do not harm the environment. Environmental Systems and Societies offers such a specific combination of environmental science and human effect and is hence suitable for students interested in sustainable engineering practices. ESS will thus equip students with the knowledge required for them to take informed decisions as to how engineering projects can impact ecosystems and human populations, with protection to ensure that infrastructure is built in an environmentally friendly manner to the ecosystem and human population.

With a growing emphasis on eco-friendly engineering, ESS gives civil engineering students the tools to prioritise sustainability in their designs, contributing to a more sustainable future.

7. Theory of Knowledge (TOK)

TOK is a core component of the IB Diploma Programme that encourages students to reflect on how knowledge is constructed and understood. For civil engineers, TOK promotes critical thinking about ethical, social, and environmental issues. It fosters an awareness of the broader implications of engineering decisions, encouraging students to consider the impact of their work on society and the environment.
