52.212-2 Evaluation -- Commercial Items (Jan 1999):
(a) The Government will award a contract resulting from this solicitation to the responsible quoter whose quote conforming to the solicitation will be most advantageous to the Government, price and other factors considered.
The Government intends to award on initial offers. Technical capability will be rated on a PASS/FAIL basis. To be technically acceptable, the offeror must receive a rating of pass in each of the minimum capability categories as described above. If the product is not technically acceptable, the Government may not conduct further proposal evaluations. However, the Government reserves the right to open discussions at the Governments discretion.
The following factors shall be used to evaluate quotes:
(i) Technical capability of the item quoted to meet the Government requirement
(ii) Past Performance
(iii) Price
Technical capability will be evaluated on a pass/fail basis. A quote that is considered technically unacceptable shall be ineligible for award. Past Performance will be evaluated to establish the degree of quality of an offerors previous contract performance for the same or similar types of contracts. Technical quotes must include descriptive literature to include copies of Warranty, Operations and Maintenance Manuals, and any other documentation that clearly demonstrates the quoters ability to meet the requirements of the solicitation at no cost to the Government. Products will be evaluated and compared to the minimum range of capabilities to determine technical acceptability. For Past Performance, a list of three (3) references for a similar type item shall be included. References shall include; name/point of contact, address, phone number, and Email address. Pricing and Cage Code will also be included. The lowest priced quote that is determined to be technically acceptable and submitted by a company with acceptable past performance shall be selected for award.

Technical quotes must include descriptive literature to include copies of Warranty, Operations and Maintenance Manuals, and any other documentation that clearly demonstrates the quoters ability to meet the requirements of the solicitation at no cost to the Government.
