Structural Engineering
A few civil engineers specialize in structural engineering, which is why they earned their degree as a structural engineer. They spend their time designing and analyzing the construction of buildings, towers, bridges, dams, and other similar structures. These projects take time to design and construct, because they need to be built in a way that will keep them safe, reliable, economical, and sustainable for the long term. Of course, they should also be quite visually appealing since hundreds or thousands of people will be looking at these items all the time. These types of projects take a lot of additional skills, especially math and physics, because that is the only way the civil engineers can ensure that each one is sturdy enough for heavy loads or stable enough for use.
