(a) Definitions. “Commercially available off-the-shelf (COTS) item,” “construction material,” “designated country construction material,” “domestic construction material,” and “foreign construction material,” as used in this provision, are defined in the clause of this solicitation entitled “Buy American—Construction Materials Under Trade Agreements” (Federal Acquisition Regulation (FAR) clause 52.225-11).

(b) Requests for determination of inapplicability. An Offeror requesting a determination regarding the inapplicability of the Buy American statute should submit the request to the Contracting Officer in time to allow a determination before submission of offers. The Offeror shall include the information and applicable supporting data required by paragraphs (c) and (d) of FAR clause 52.225-11 in the request.

(c) Evaluation of offers.

(1) The Government will evaluate an offer requesting exception to the requirements of the Buy American statute, based on claimed unreasonable cost of domestic construction materials, by adding to the offered price the appropriate percentage of the cost of such foreign construction material, as specified in paragraph (b)(4)(i) of FAR clause 52.225-11.

(2) If evaluation results in a tie between an Offeror that requested the substitution of foreign construction material based on unreasonable cost and an Offeror that did not request an exception, the Contracting Officer will award to the Offeror that did not request an exception based on unreasonable cost.

(d) Alternate offers.

(1) When an offer includes foreign construction material, other than designated country construction material, that is not listed by the Government in this solicitation in paragraph (b)(3) of FAR clause 52.225-11, the Offeror also may submit an alternate offer based on use of equivalent domestic or designated country construction material.

(2) If an alternate offer is submitted, the Offeror shall submit a separate Standard Form 1442 for the alternate offer, and a separate price comparison table prepared in accordance with paragraphs (c) and (d) of FAR clause 52.225-11 for the offer that is based on the use of any foreign construction material for which the Government has not yet determined an exception applies.

1452.215-71 USE AND DISCLOSURE OF PROPOSAL INFORMATION—DEPARTMENT OF THE

INTERIOR (APR 1984)

(a) Definitions. For the purposes of this provision and the Freedom of Information Act (5 U.S.C. 552), the following terms shall have the meaning set forth below:

(1) “Trade Secret” means an unpatented, secret, commercially valuable plan, appliance, formula, or process, which is used for making, preparing, compounding, treating or processing articles or materials which are trade commodities.

(2) “Confidential commercial or financial information” means any business information (other than trade secrets) which is exempt from the mandatory disclosure requirement of the Freedom of Information Act, 5 U.S.C. 552.

Exemptions from mandatory disclosure which may be applicable to business information contained in proposals include exemption (4), which covers “commercial and financial information obtained from a person and privileged or confidential,” and exemption (9), which covers “geological and geophysical information, including maps, concerning wells.”

(b) If the Offeror, or its Subcontractor(s), believes that the proposal contains trade secrets or confidential commercial or financial information exempt from disclosure under the Freedom of Information Act, (5 U.S.C. 552), the cover page of each copy of the proposal shall be marked with the following legend:

“The information specifically identified on pages of this proposal constitutes trade secrets or confidential commercial and financial information which the Offeror believes to be exempt from disclosure under the Freedom of Information Act. The Offeror requests that this information not be disclosed to the public, except as may be required by law. The Offeror also requests that this information not be used in whole or part by the government for any purpose other than to evaluate the proposal, except that if a contract is awarded to the Offeror as a result of or in connection with the submission of the proposal, the Government shall have the right to use the information to the extent provided in the contract.”

(c) The Offeror shall also specifically identify trade secret information and confidential commercial and financial information on the pages of the proposal on which it appears and shall mark each such page with the following legend:

“This page contains trade secrets or confidential commercial and financial information which the Offeror believes to be exempt from disclosure under the Freedom of Information Act and which is subject to the legend contained on the cover page of this proposal.”

(a) Information in a proposal identified by an Offeror as trade secret information or confidential commercial and financial information shall be used by the Government only for the purpose of evaluating the proposal, except that

(i) if a contract is awarded to the Offeror as a result of or in connection with submission of the proposal, the Government shall have the right to use the information as provided in the contract, and (ii) if the same information is obtained from another source without restriction it may be used without restriction.

(b) If a request under the Freedom of Information Act seeks access to information in a proposal identified as trade secret information or confidential commercial and financial information, full consideration will be given to the Offeror's view that the information constitutes trade secrets or confidential commercial or financial information. The Offeror will also be promptly notified of the request and given an opportunity to provide additional evidence and argument in support of its position, unless administratively unfeasible to do so. If it is determined that information claimed by the Offeror to be trade secret information or confidential commercial or financial information is not exempt from disclosure under the Freedom of Information Act, the Offeror will be notified of this determination prior to disclosure of the information.

(c) The Government assumes no liability for the disclosure or use of information contained in a proposal if not marked in accordance with paragraphs (b) and (c) of this provision. If a request under the Freedom of Information Act is made for information in a proposal not marked in accordance with paragraphs (b) and (c) of this provision, the

Solicitation No.

140P2026R0078

National Park Service (NPS) – Denver Service Center (DSC) YELL 326141 – Yellowstone Modular Housing

Offeror concerned shall be promptly notified of the request and given an opportunity to provide its position to the Government. However, failure of an Offeror to mark information contained in a proposal as trade secret information or confidential commercial or financial information will be treated by the Government as evidence that the information is not exempt from disclosure under the Freedom of Information Act, absent a showing that the failure to mark was due to unusual or extenuating circumstances, such as a showing that the Offeror had intended to mark, but that markings were omitted from the Offeror's proposal due to clerical error.

SPECIAL INSTRUCTION: BRAND NAME OR EQUAL
