We are responding to a DHS RFP. It requires 3 past performance write ups AND 3 Past Performance Questionnaires. The PP Questionnaires are to be sent to the Project's COR or CO and then they are to send it directly to the RFP POC. The RFP allows us to submit past performances in which we were not the prime. We sent a PP questionnaire to a COR on a project in which we were a sub (the only sub). However, the COR stated that he cannot fill out the questionnaire because we're not the prime, neither can the prime fill out the questionnaire for us because they are a private company. He said he is contractually unable to fill it out. I have sent out many of these questionnaires in the past and have never received a response like that. In the past the COR/CO has completed it and sent it along, regardless of if we were a prime or sub. I have been looking through the FAR, but all I can find is info relating to the prime contractor. I don't see anything that actually addresses the Gov't filling out a PP questionnaire or giving a rating to a subcontractor. Anyone have any advice, reference, anything that can prove that this is allowed?
