During the course of the on-line auction, offerors' proposed prices will be publicly disclosed to other offerors and anyone else having access to the on-line auction. This public disclosure is anonymous, meaning that each offeror's identity will be concealed from other offerors (although it will be known to the Government), and only generic identifiers will be used publicly for each offeror's proposed pricing (e.g., "Offeror A"). By submitting a proposal in response to the solicitation, offerors agree to participate in the Reverse Auction and that their prices may be publicly disclosed, including to other offerors, during the Reverse Auction. An offeror's final auction price will be considered its final proposal revision. No price revisions will be accepted after the close of the Reverse Auction, unless the Contracting Officer decides that further discussions are needed and final proposal revisions are again requested in accordance with FAR 15.307.  Various increments solicited:  from 10 each to 24 each; from 25 each to 49 each; from 50 each to 99 each; from 100 each to 249 each; from 250 each to 499 each, from 500 each to 999 each.  Proposed procurement contains a 100% option for increased quantities.  This proposed procurement includes a family group of items within the Federal Supply Class 5962.  This acquisition is for supplies for which the Government does not possess complete, unrestrictive technical data; therefore, the Government intends to solicit and contract with only approved sources under the authority of 10 U.S.C. 2304(c)(1).  Approved sources are:  Natel Engineering Company, Inc. (09059). While price may be a significant factor in the evaluation of offers, the final award decision will be based upon a combination of price, delivery, past performance and other evaluation factors as described in the solicitation.
