I'm doing mechanical engineering, but I have several friends that are doing civ-eng. They like it.
Civ-engs basically builds all the buildings/bridges/highways you see around you.
Just a tip though, if you want to do engineering, make sure that you are motivated up the ying yang. Cause, it's a really tough course with an extreme workload. Today was my last day of semester and I had 4 assignments due, and in the last 7 weeks I've had 38 assignments. And they were all huge.
