Thank you all for your helpful responses. I realise that I will have to discuss with the Client, however I was hoping for an idea from someone who had worked with or heard of the term before I approach the Client. If there are any oil and gas people out there who have heard of the term, I would much appreciate your information. Failing that I intend to go with a list of open quality issues such as NC, CA, etc. I have this fear that they may want the quality manager to handle all issues, including design and construction. Not a good way to go unless authority is adequate. I will let you know what the Client finally requested.
