My wife was a builder until they stopped doing that. She had a pretty sharp learning curve and it took a while to get the confidence of the men around her but you can do it.
Just don't ask for any special consideration because you are a girl and try to be right when you say something. You may not have the same strength as some of the guys but there is nothing that keeps you from knowing as much ... or more. Ask the question if you are confused and try to absorb as much of the answer as you can. Go home and look up the things that are not clear to you. The bad news is there is still a whole lot for you to learn, the good news is guys like telling girls how to do things ... at least the ones who secure in their own manhood.
If you are one of the lucky people who have the innate ability to fix things (something you really can't teach) you may become a star.
