(S-90) When GFP is anticipated, include enclosure 18b, GFP Attachment ( https://www.ditco.disa.mil/Contracts/SampleDocTemplates ) 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.
