The identical numerical sequence stated in the attached technical scope of work/product description must be used in the compliance statement. Each paragraph of the scope of work/ product description must clearly indicate a response with one of the following statements:

A. EXCEEDS - Where the offeror surpasses the requirement, a narrative description shall be provided.

B. COMPLY - Where the offeror meets the requirement the compliance statement should reflect comply. No narrative is required to be provided unless requested.

C. EXCEPTION TO - Where the offeror takes exception to the requirement, a narrative description shall be provided.

Offerors who do not provide sufficient technical data for evaluation (by the methods noted above); may be rejected without further consideration. The supplying of standard commercial literature shall not be construed as compliance unless it is complete in all details as to permit a technical evaluation in accordance with these instructions. Descriptive literature shall be written in English and all dimensions, capacities, and ratings given in the US system of measurements.

Information submitted other than as herein described will not be translated or converted by the Government to determine product conformance or acceptability.

2.4 Past Performance Data: Past performance shall be used as an evaluation factor within the Lowest Price Technically Acceptable (LPTA) process. The Government intends to collect and evaluate prior contract performance data to assess each Offeror’s ability to supply the products and services required and the quality of the manufacturer’s product quoted for this procurement.

The Government may use any and all past performance data at its disposal in evaluating an Offeror’s demonstrated record of performance. This may include review of contracts issued by any branch of the federal government, whether manual or electronic, past or present, and any commercial contracts identified by the Offeror.

The information provided is considered sensitive and shall not be released to the Offeror. All information is subject to verification by the Government during the evaluation. The Government reserves the right to contact the Government or commercial points of contacts identified, or contacts for other contracts performed, for the purpose of verifying information concerning past performance and/or to obtain additional information.

Evaluation of the past performance surveys received will occur in accordance with Past Performance as addressed in section 3.0.2.

The government will use any and all past performance data at its disposal in evaluating the quality of the product quoted to determine the best value. Data collected from government or commercial sources on previously supplied same/similar manufacturing machines can be used to determine the product quoted is not satisfactory and determined not to be the best value.

3.0 Source Selection Process: Offers shall be evaluated utilizing the Lowest Price Technically Acceptable (LPTA) source selection process. This process determines the best value to the Government to be the lowest priced quote that is determined acceptable in all non-price factors, which consists of technical and past performance. Quotes that are determined acceptable for both the technical and past performance factors will be determined technically acceptable quote.

Value is not recognized from a quote that exceeds the Government’s technical or performance requirements.

3.0.1. Technical Review Rating. The technical review determines whether the offer will satisfy the Government’s requirements. All responsive Offerors will have their non-priced technical quotes evaluated to determine if they demonstrate a thorough knowledge and understanding of the technical requirements, as well as provide a sound, compliant approach to executing all areas of performance. The following ratings will be used:

Technical Rating Description

Acceptable Quote clearly meets the minimum requirements of the solicitation.

Unacceptable Quote does not clearly meet the minimum requirements of the solicitation.

3.0.2 Past Performance, Experience, and Quality Rating. Offers will be evaluated based on past performance, experience, and the quality of the product. Past performance describes how well contractors executed what was promised in a quote and the quality of the product quoted. Experience reflects whether contractors have performed similar work before. This part of the evaluation process enables the Government to assess the competence of an Offeror to supply the required products and services based on a demonstrated record of past performance.

The following ratings will be used:

*Note: In the case of an offeror without a record of relevant past performance or for whom information on past performance is not available or so sparse that no meaningful past performance rating can be reasonably assigned, the offeror will not be evaluated favorably or unfavorably on past performance.

Therefore, the offeror shall be determined to have unknown past performance.

In the context of acceptability/unacceptability, “unknown” shall be considered “acceptable.”

There are two aspects to the past performance evaluation. The first is to evaluate whether the offeror’s present/past performance is relevant or not relevant to the effort to be acquired. The second aspect of the past performance evaluation is to determine how well the contractor performed on the contracts. Each aspect will be evaluated on an Acceptable/Unacceptable basis to determine an overall past performance rating.

The Government will utilize any data available, including information on total equipment effectiveness matters such as availability, performance, and quality, when evaluating past performance.

In order to collect adequate and relevant past performance information on the Offeror’s ability to supply the product/service, a Past Performance Questionnaire (PPQ) is included as an attachment to the RFQ for use in determining how well the prospective Offeror performed for another business. The prospective Offeror should annotate its company name at the top of the form, then send a copy to at least five businesses for which it has

Past Performance Rating Description

Acceptable

Based on the offeror’s performance record, the Government has a reasonable expectation that the offeror will successfully perform the required effort, or the offeror’s performance record is unknown*.

Unacceptable Based on the offeror’s performance record, the Government has no reasonable expectation that the offeror will be able to successfully perform the required effort.

previously (or currently) provided same or similar products or services. The completed evaluation forms must be returned from the third party directly to the Contracting Officer.

Completed forms received from the Offeror will not be accepted.

If past performance information has been provided on a solicitation within the last six months for the same or similar item, provide that Purchase Request Number with your offer and request that the Past Performance Questionnaire’s be utilized for this solicitation.

3.0.3 Price Reasonableness/Support. All responsive, technically acceptable (based on technical and past performance evaluation ratings) quotes will be evaluated for Price Reasonableness. Unrealistically low proposed prices, initially or subsequently, may be grounds for eliminating a quote from competition either on the basis that the Offeror does not understand the requirements or that the Offeror has submitted an unrealistic quote.

Price Reasonableness will be evaluated as described below:

A. Reasonableness: Adequate price competition is expected to support the determination of reasonableness. Price or cost analysis techniques may be used to further validate price reasonableness. If adequate price competition is not obtained or if price reasonableness cannot be determined using price analysis of Government obtained information, additional information will be required to support the proposed price.

B. Support: A quantity of two (2) Commercial invoices reflecting the same/similar item has been sold to other commercial customers is requested to be provided with quote.
