Draftsmen are being phased out. This should be pretty clear by now.
GIS and BIM are indeed hot right now, and users typically have a Geography (for GIS) or engineering degree. To be a rodman, inspector, etc., you don't need a BS in Eng. or even in Eng. Techology, and their salaries reflect that.
I feel that you are leery of enrolling in a BSCE program, and might prefer the CET degree because of being more hands-on, or less difficult, or because of your age or whatever the reason is. Fine, but keep in mind that, as mentioned by others, your options will be much more limited with a CET degree and, based on my own experience in working with CET degree holders, you will lack advanced knowledge of fluid mechanics, numerical analysis, modeling, etc.
Contrary to what others think, I do think that age is a factor, mostly because of lack of experience when you join the workforce. But there's little you can do about it and it may be a factor regardless of your degree. However, it's not an insurmountable obstacle and you might be able to use it to your advantage (maturity coupled with knowledge of the latest and greatest tools they teach you to use at school).
If you can, get a standard Eng. degree. And yes, learn GIS, BIM, project controls, MATLAB, modeling, technical writing, etc.
