There’s no point in getting a double major if you’re getting an engineering degree. Also, civil is probably the least appealing, most underpaid major (very specific field)…Least appealing because of low pay in industry. Change you major to mechanical instead and get your EIT, then PE eventually. Especially if you like fluid mechanics/dynamics. If you’re not too far along in your degree, I would highly suggest you change it now. Don’t do civil. I’m a mechanical engineering graduate working for an international fortune 250 EPC company. You can learn the civil stuff on the job. Mechanical engineers are the most diverse engineers and would provide you with the most career opportunities. You can find a career in structural, piping, or electrical. Having been in the industry I can tell you it’s pointless to get a double major in economics, comp sci, or finance/management. Every company does things differently and you will certainly learn engineering economics and programming on the job. Just save your time and money on a double major and switch to mechanical since your favorite course is fluid mechanics (I personally enjoyed thermo the most). You’d be surprised at how easy it might be to change from civil to mechanical since many courses overlap. Good luck!
