W912HZ26RA002 Questions and Answers

Question 1. We are performing independent research on the Combined Synopsis/Solicitation (W912HZ26RA002). We would like to know if this is a brand-new contract OR if there is (was) an incumbent performing these services. If not brand new, could you please provide the current / previous contract number?

Answer 1. This is a brand-new requirement.

Question 2. Please confirm the deadline for submission of questions is October 27th, 2025.

Answer 2. The Deadline to submit questions is October 27, 2025.

Question 3. Additionally, we noticed a discrepancy between the Technical Exhibit titles listed in the RFP and the Attachment file names provided. For example: Technical Exhibit C - Homogenization SOP is listed as Attachment 6, but the document is titled Attachment 6 - Technical Exhibit D; Technical Exhibit D - Example Field Sheet is listed as Attachment 7, but the document is titled Attachment 7 - Technical Exhibit E; Technical Exhibit E - Example Chain of Custody Form is listed as Attachment 8, but the document is titled Attachment 8 - Technical Exhibit F.

Answer 3. Confirmed, any potential proposal references to attachments should align with the names on the documents themselves and the titles and numbering as listed in the RFP. The titles within the documents listed as Attachments 6-8 have been corrected to list the correct Technical Exhibit to correspond with their title and their title referenced in the solicitation. The title within each attachment now corresponds with its named title and read as follows: a. Attachment 6 - Technical Exhibit C - Homogenization SOP b. Attachment 7 - Technical Exhibit D - Example Field Sheet c. Attachment 8 - Technical Exhibit E -Example Chain of Custody Form

Question 4. Could you please confirm whether any potential proposal references to attachments should align with the names on the documents themselves or with the titles and numbering as listed in the RFP?

Answer 4. Confirmed, any potential proposal references to attachments should align with the names on the documents themselves and the titles and numbering as listed in the RFP.

Question 5. Additionally, with the potential for a federal government shutdown, could you please confirm whether any delays or schedule adjustments are anticipated for this solicitation?

Answer 5. This is to confirm at this time due to the federal government shutdown, there are no anticipated delays or schedule adjustments for this solicitation.
