(c) Limitations. When using the authority of FAR 6.302-3(a)(2)(ii), the contracting officer must ensure that the technical and requirements personnel’s certifications required by FAR 6.303-1(b) and FAR 6.303-2(b) contain a statement that the proposed effort has been reviewed to assure that it falls within the charter or special capabilities of the proposed institution and establishes or maintains (as appropriate) an essential engineering, research or development capability to be provided by an educational or other non-profit institution or a federally funded research and development center (FFRDC). In addition, when proposing to contract directly with an FFRDC not sponsored by the contracting activity, the contracting officer must ensure that the requirements personnel have included with the procurement request a written confirmation from the sponsoring agency that the proposed effort falls within the purpose, mission and general scope of effort or special competency of the FFRDC. (See FAR 17.504(e).)
