Not a bad idea but let me inject a little bit of reality that makes any engineering program a challenge as a part-time adult student. At a minimum, you have to go into it knowing the choices to be made to successfully complete the program.
The biggest hurdle occurs in the senior year and is known as the senior capstone project. This is at least a one-semester undertaking, sometimes two semesters. The student project groups work with people in industry on real projects that require real solutions. This means you will have to attend meetings and conduct project work on regular business hours. This can be a hurdle for students that have daytime jobs while attending evening classes. Thus, the need to be aware of choices that students will have to make to succeed in the program. It’s not impossible for a focused and dedicated student but they should go into the process with their eyes open.
I agree that there would come a time in most programs where you would have to take a semester or nine months off work entirely and tackle the toughest portion of your degree program.
I think that would also allow you to orient your major final courses toward your particular expected final field of employment and expertise.. Central Plant, power generation, process plant work, new commercial construction and the whole variety would be laid out for your choice.
I have had some fine young engineers that went right into construction with good success — but I am focused on the issue of debt and making an opportunity to have what ever you learn in underclassman courses directly apply.
