B08 - Instructions to Offerors - OM LPTA.pdf

I. Type of Contract:

II. Quote Instructions:

III. Specific Quote Instructions

1) The vendor shall submit a complete price quote for all products and services identified in the requirements document. Quote should include:

A total firm-fixed price covering the full requirement.

Descriptive literature (including pictures when applicable) that clearly identifies the proposed product or service and provides sufficient detail to enable the Government to determine compliance with all requirements specified in the RFQ.

IV. Evaluation Factors (LPTA)

This acquisition uses the Lowest Price Technically Acceptable (LPTA) source selection process. Technical and past performance factors will be evaluated on an acceptable/unacceptable basis. No tradeoffs will be made.

1) Factor 1 – Technical Acceptability (Pass/Fail)

The Government will evaluate the offeror’s quote to verify compliance with all requirements in the RFQ and requirements document.

Pass: Quote meets all mandatory requirements.

Fail: Quote does not meet one or more mandatory requirements.

2) Factor 2 – Past Performance (Pass/Fail)

Past performance will be evaluated to determine acceptability only. The Government will review past performance information from CPARS, agency records, or other sources.

Acceptability: Offeror demonstrates satisfactory performance on similar contracts and has no terminations for cause or default within the past three (3) years.

Unacceptability: Offeror has a record of unsatisfactory performance or one or more terminations for cause or default within the past three (3) years.

Neutral: If no past performance information is available, the offeror will receive a “neutral” rating, which will be treated as acceptable.

3) Factor 3 – Price

Price will be evaluated for reasonableness and completeness. Award will be made to the lowest-priced offeror whose quote is technically acceptable and whose past performance is acceptable.

V. Bais of Award

Award will be made to the responsible offeror submitting the lowest-priced, technically acceptable quote. The Government intends to award without discussions; however, the Contracting Officer reserves the right to conduct discussions if necessary.
