(S-90) When GFP is anticipated, include enclosure 18b, GFP Attachment ( https://www.ditco.disa.mil/contracts/SampleDocTemplates.asp ) or the downloaded GFP attachment from the GFP module ( https://piee.eb.mil /), in all solicitations.

For letter solicitations, or any solicitation not using a standard 13 digit solicitation number, the GFP Attachment Excel document at 18b is the preferred format.

When the amount of GFP could vary in performance based acquisitions or other similar acquisition types, the GFP Attachment Excel document may list a reasonable range for the quantity of GFP to be provided in the solicitation. This will allow the offeror to propose the exact number of GFP items within the listed range.
