They will stop about 3:15 pm and roll up everything.But if this is a typical GC, he will have more than one job going at any given time - he has to to keep his crews employed....there will be times on your project when a Sub-Contr is on-site and the GCs crews will take off (i.e., demo is one of those times, painting is another)....so don't freak out if they aren't there some days, it's very typical as I said.The main thing that slows down a project is the customer making changes, so avoid changing anything once you start...also you should have a very clear and concise Scope Of Work to avoid conflict later on, like "what kind of tile goes where", "where do the pendant lights go"?
