(1) Is available to the Government without restriction from another source;
(2) Closely resembles a pending competitive acquisition requirement;
(3) Does not relate to the activity's mission; or
(4) Does not demonstrate an innovative and unique method, approach, or concept, or is otherwise not deemed a meritorious proposal.
(b) The contracting officer may commence negotiations on a sole source basis only when -
(1) An unsolicited proposal has received a favorable comprehensive evaluation;
(3) The agency technical office sponsoring the contract furnishes the necessary funds; and
(4) The contracting officer has complied with the synopsis requirements of subpart 5.2.
