Submission of CUI Supporting Documentation:

If within an Offeror's proposal, the supporting documentation is marked CUI, Offerors shall submit the specific CUI supporting documentation exclusively through DoD Safe, https://safe.apps.mil/. This is just the specific CUI supporting document. Offerors shall not submit its proposal nor non-CUI supporting documentation through DoD Safe. Within the Offeror's proposal, if the requested supporting documentation is marked CUI, the Offeror shall annotate within the appropriate Volume and Section that the supporting documentation is marked CUI, what the CUI documents are, state the total page count for the CUI document(s), and confirm that these CUI documents have been submitted via DoD Safe. Again, DoD Safe shall not be used for submission of the Offeror's proposal or any non-CUI files; just the specific CUI documentation. Only the designated CUI documentation will be evaluated from DoD SAFE submissions. Any non-CUI files uploaded will not be evaluated. If the Offeror submits any supporting documentation through DoD SAFE Offerors shall name the documents as follows:

*Offerors shall replace “xxxx” with the Offerors name.

*Offerors shall replace “DOCUMENTNAME” with the Supporting Documentation that has been annotated on the proposal.
