Mr. Woehl, I work for an engineering firm in Nebraska, and each state has their own way they do things. In Nebraska, it is required for the firm to submit their prints to the local authorities before a building permit is ever issued. They will review the prints and make comments and return them to you, sometimes asking (demanding) certain changes, other times simply asking for clarification. It is very rare that a set of prints gets approved with no red lines (corrections). They usually find something they don't like. Often, if you show a willingness to comply (instead of fighting them) they are more inclined to have some leniency. If you make them mad, you will never ever see the light of day, and alles kaput. The previous replies will also be helpfull to you. Sincerely, Konrad
