GOVBIDFIT SCREENING LENS
What deserves attention before you spend bid time
These screening signals are generated from the public notice fields stored for this specific opportunity. They are not eligibility findings or predictions; they are prompts for a faster, more disciplined review of the official solicitation.
This record is in a solicitation stage, so submission instructions, evaluation factors, attachments and amendments should be reviewed before a bid/no-bid decision.
The stored response date leaves more than ten days, but amendments and pre-response milestones can shorten the usable preparation window.
The current feed does not show a program-specific set-aside restriction. That does not remove other eligibility, responsibility, registration or solicitation-specific requirements.
NAICS 541715 · PSC AJ13 is the recorded classification. Use it as a screening clue, then compare the actual scope and deliverables rather than treating the code alone as proof of fit.
GovBidFit stores 5 notices tied to this solicitation. Review the notice chain and official SAM.gov history because later postings can change dates, scope or instructions.
GovBidFit stores the source notice text, but its length does not prove the requirements are complete. Review official attachments, clauses, amendments and Q&A before relying on the description.
The source data includes 2 public contracting contacts. Use the solicitation's stated communication rules and deadlines before contacting the buyer.
Questions to resolve next
What this opportunity record tells you
SAM.gov identifies this as a solicitation from DEPT OF DEFENSE. The record was posted on October 2, 2026 and currently lists September 30, 2027 as the response deadline. GovBidFit keeps source facts separate from its matching guidance so you can see what comes from the federal notice.
The listed product or service classification is NAICS 541715 · Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology) · PSC AJ13. The set-aside field is Unrestricted. These fields help narrow your search, but they do not replace the full solicitation, amendments, attachments, clauses or eligibility language on the official source.
