My bad bro, I guess I was having a retarded moment when reading your post
The cycle DIV laid out for you will be fine and should produce good results.
Don't worry about the construction thing or let that get you down. I've been working in construction since I graduated high school...nothing easy, framing, concrete work, all the stuff that can beat you down, so I can attest that training w/this job can be done successfully. Granted I've always had my home and my own bed to go back to, so in that regard things are going to be a little tougher for you. But keep your head on straight, stay motivated and train smart and you should be fine.
I'll say this though, there is nothing enjoyable about working in construction and BB at the same time...it can take a serious toll on your body, especially when in dieting down mode...that's absolutely hell on earth. Luckily for me I plan on getting out of this line of work fairly soon.
