48 CFR § 9.106-1 - Conditions for preaward surveys.
(a) A preaward survey is normally required only when the information on hand or readily available to the contracting officer, including information from commercial sources, is not sufficient to make a determination regarding responsibility. In addition, if the contemplated contract will have a fixed price at or below the simplified acquisition threshold or will involve the acquisition of commercial products or commercial services (see part 12), the contracting officer should not request a preaward survey unless circumstances justify its cost.
(b) When a cognizant contract administration office becomes aware of a prospective award to a contractor about which unfavorable information exists and no preaward survey has been requested, it shall promptly obtain and transmit details to the contracting officer.
(c) Before beginning a preaward survey, the surveying activity shall ascertain whether the prospective contractor is debarred, suspended, or ineligible (see subpart 9.4). If the prospective contractor is debarred, suspended, or ineligible, the surveying activity shall advise the contracting officer promptly and not proceed with the preaward survey unless specifically requested to do so by the contracting officer.
