Structural engineers design, plan and oversee the construction of new buildings and bridges, or alterations and extensions to existing properties or other structures. It can be very satisfying to have the chance to see something you’ve had a part in become a reality. As a structural engineer, you’ll design structures to withstand stresses and pressures imposed through environmental conditions and human use. You’ll ensure buildings and other structures do not deflect, rotate, vibrate excessively or collapse and that they remain stable and secure throughout their use.
