My advice to you would be to enroll in a CAD class and while you are taking that class hire on as a grunt on a line crew so you can begin to learn proper construction practices as well as the nomenclature used on the prints you will be working from. Ask a lot of questions and pay attention to the old timers. Then once you have a fair handle on that information you could then find a field engineer to work for while you are honing your skills. Be ready to work very hard, sweat a lot and never do motel mapping. You must always do your clean-up, and everyone has clean-up. Experience counts more than a piece of paper with fancy writing on it.
