I can attest to this. I worked with a large environmental contractor as a journeyman in the field for several years. My advice to him is to take night courses and pound out a two year program. It is well worth it!
If you like construction, you the program will be over before you know it. There is a whole other side to the construction projects including process,procedures, invoicing, negotiating, scheduling, etc. Good luck!
And hard works pay off. Look to your local builders exchange and AGC because there are many scholarships available.
