48 CFR 17.206 - Evaluation.
(a) In awarding the basic contract, the contracting officer shall, except as provided in paragraph (b) of this section, evaluate offers for any option quantities or periods contained in a solicitation when it has been determined prior to soliciting offers that the Government is likely to exercise the options. (See 17.208.)
(b) The contracting officer need not evaluate offers for any option quantities when it is determined that evaluation would not be in the best interests of the Government and this determination is approved at a level above the contracting officer. An example of a circumstance that may support a determination not to evaluate offers for option quantities is when there is a reasonable certainty that funds will be unavailable to permit exercise of the option.
