(a) Unclassified Proposals. In most cases, the best practice is to require offerors to submit proposals and modifications to the issuing contracting office. You may chose to use the local Business Service Center (BSC) for receipt and safeguarding of proposals. If so, make appropriate arrangements with the BSC.
(b) Classified Proposals. Handle classified proposals and quotations according to 504.4, 41 CFR Part 105-60, and GSA Freedom of Information Act procedures at http://www.gsa.gov/staff/c/ca/FOIA/FoiaProc/mainpage.html.
(c) Recording of offers. Abstracts help to summarize key aspects of proposals when you receive multiple responses to a solicitation (see FAR 4.803(a)(10)).
(1) You may use GSA or Standard Forms prescribed for abstracting bids in sealed bidding to abstract proposals or quotations in competitively negotiated procurements. You may modify the forms to include the information necessary for evaluation.
(2) Abstracts contain contractor bid or proposal information and source selection information. See FAR 15.201, 15.207, 15.306, 15.5, and 24.2 about disclosing information.
