Can anyone recommend a any good books? I was impressed with his estimating book. I was thinking of purchasing that big library for $1500. then I thought to myself most likely I would never read all that in 2 years. If you could purchase a course what would it be? something like calculations, grounding and bonding? I was thinking grounding and bonding. I am not looking for something specific. just looking to broaden my knowledge. I don't want to get a crap book. You can PM me about items Not sure of the rules for this question.
