Erection & commissioning of new pharma plant

pls give some guidance for the roll of qa in erection & commissioning of new pharma plant & the documentation to be done since i am totally blank from where to start since civil work is being started so which documents are to be prepared.

I would think that a review of the Basis of Design would be in order. Review any other reference to that document, and then you would have input to the Validation Master Plan and the Commissioning and Qualification Master Plan to start.
