(a) The contracting officer shall not complete the initial evaluation of any proposal when it is determined that the proposal is unacceptable because:

(1) It does not represent a reasonable initial effort to address the essential requirements of the RFP or clearly demonstrates that the offeror does not understand the requirements;

(2) In research and development acquisitions, a substantial design drawback is evident in the proposal, and sufficient correction or improvement to consider the proposal acceptable would require virtually an entirely new technical proposal; or

(3) It contains major deficiencies or omissions or out-of-line costs which discussions with the offeror could not reasonably be expected to cure.

(b) The contracting officer shall document the rationale for discontinuing the initial evaluation of a proposal in accordance with this section.

(c)(2) A total of no more than three proposals shall be a working goal in establishing the competitive range. Field installations may establish procedures for approval of competitive range determinations commensurate with the complexity or dollar value of an acquisition.

(e)

(1) In no case shall the contacting officer relax or amend RFP requirements for any offeror without amending the RFP and permitting the other offerors an opportunity to propose against the relaxed requirements.
