The nature and scope of the onsite review in each instance will vary depending on the type of compliance evaluation a CO is conducting. They may also vary depending on whether the CO has already identified potential problems during the desk audit phase. As far as the lead time is concerned, in preparation for the onsite review, the CO must contact the contractor, or the contractor’s representative, to schedule the onsite review, request any additional information, and identify the contractor officials who will need to be available during the onsite visit. The CO must also inform the contractor that he or she may need additional information and interviews as the onsite review progresses. Having such a discussion prior to the onsite visit provides the contractor with time to locate and make available requested information and interviewees. It also provides notice that the CO may make additional requests for data and interviews. The CO must provide the contractor with written confirmation of the onsite date(s) and time(s) at least three business days prior to the onsite. This confirmation must also include requests for other data and information that the CO is aware of at that time. The confirmation is sent to the contractor by certified mail, return receipt requested; however, a courtesy copy may be sent by email or facsimile.
