4) Offerors shall provide a specific narrative explanation of any contract(s) submitted for Factor 2 – Past Performance, describing the objectives achieved and detailing how the effort is relevant to the requirement of this RFP. Offerors should submit contracts with similarity of service/support, complexity, dollar value, contract type, and degree of subcontract/teaming.

In the case of an Offeror without a record of relevant past performance or for whom information on past performance is not available, the Offeror may not be evaluated favorably or unfavorably on past performance. A summary chart that shows which relevant features have been met for each contract will not be sufficient for demonstration of relevancy.

i) The contractor team agreement or commitment shall be provided in Volume IV. Teaming agreements will be evaluated under Factor 2. If a teaming agreement or commitment is not provided, the contracts and experience of any team members outside of the Offeror will not be considered.

c) General Instructions. This section is to inform the Offeror of the information submittal requirements to evaluate the Completeness, Reasonableness, and Balance of Offeror’s proposed prices. Compliance with these requirements is mandatory, and failure to comply may result in rejection of Offeror’s proposal.

1) The responsibility to substantiate the credibility of proposed prices rests with the

Offeror at the time of proposal or during subsequent discussions (if any are held).

2) Compliance with these instructions is mandatory.

3) Failure to comply may render the proposal ineligible for award.

4) Data beyond that required by this instruction shall not be submitted unless it is considered essential to the document or to support the price.

5) All information relating to the proposed price must be included in the section of the proposal designated as the price volume.

6) In accordance with FAR 15.305 (a)(1), adequate price competition is anticipated, which will establish price reasonableness. However, if after receipt of proposals, the Contracting Officer determines that there is inadequate price competition, and none of the exceptions in FAR 15.403-1 apply, the Offeror shall be required to submit cost or pricing data.

7) Unreasonably high Total Evaluated Price (TEP) may be grounds for eliminating a proposal from the competition. Unbalanced pricing may also be grounds for eliminating a proposal from competition if the unbalanced pricing is determined to present an unacceptable risk to the Government.

8) The Offeror shall propose a price on a FFP basis in accordance with the proposed Contract Line Item (CLIN)/SubCLIN structure.

9) Price Proposal documents shall not be password protected.

10) All Microsoft Excel spreadsheets shall be submitted in Microsoft Excel format and

Sub-CLINs will be utilized IAW CLIN/Sub-CLIN Structure and Guidance provided in the PWS. Prices proposed for Sub-CLINs must equal the parent CLIN total proposed for the applicable site.

e) EXCHANGES

1) The Government intends to award without discussions, and make an award based on initial proposals; however, discussions or negotiations may be held and result in a Final Proposal Revision (FPR). If it is determined to be in the best interest of the Government to hold discussions, the Government will make a Competitive Range determination, Evaluation Notices (ENs) may be issued to Offerors in the competitive range, responses will be requested from applicable Offerors, and discussions will be opened. The competitive range may be further reduced for purposes of efficiency pursuant to FAR 15.306(c)(2). Formal responses to ENs (if applicable), discussion items, and final proposal revisions will be considered in making the award decision.

2) Any revision or non-concurrences to contract terms and conditions submitted in the FPR may not be subject to further discussion and may render the proposal unacceptable to the Government. This provision is not intended to restrict the Offeror’s opportunity to revise figures (e.g., prices, rates, etc.); rather, it is intended to preclude any misunderstandings by the Government, which could result if new or revised terms and conditions are submitted in the FPR that have not been fully disclosed, discussed, and understood during discussions. Hence, such new or revised terms and conditions are not solicited and, if submitted in the FPR, may render the proposal unacceptable to the Government.

3) Offerors are cautioned to submit sufficient information in the format specified in Section L. Offerors may be asked to clarify certain aspects of their proposal.

Communication conducted to resolve minor or clerical errors will not constitute discussions and the Contracting Officer reserves the right to award a contract without the opportunity for proposal revision.
