GOVBIDFIT SCREENING LENS

What deserves attention before you spend bid time

Decision support

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.

Active solicitation stage

This record is in a solicitation stage, so submission instructions, evaluation factors, attachments and amendments should be reviewed before a bid/no-bid decision.

Planning window available

The stored response date leaves more than ten days, but amendments and pre-response milestones can shorten the usable preparation window.

No socioeconomic restriction recorded

The current feed does not show a program-specific set-aside restriction. That does not remove other eligibility, responsibility, registration or solicitation-specific requirements.

Classification signal

NAICS 237990 · PSC Y1PZ 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.

Notice history exists

GovBidFit stores 7 notices tied to this solicitation. Review the notice chain and official SAM.gov history because later postings can change dates, scope or instructions.

Official description stored

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.

Public buyer contact available

The source data includes 2 public contracting contacts. Use the solicitation's stated communication rules and deadlines before contacting the buyer.

What this opportunity record tells you

SAM.gov identifies this as a solicitation from DEPT OF DEFENSE. The record was posted on October 21, 2026 and currently lists December 9, 2026 as the response deadline. GovBidFit keeps source facts separate from its matching guidance so you can see what comes from the federal notice.

Before deciding to bid

Read the complete official description and scope. Verify the exact response date, time and time zone on SAM.gov. Confirm NAICS/PSC and every set-aside eligibility requirement. Review attachments, amendments, Q&A and submission instructions. Check place of performance, staffing, insurance, bonding and execution requirements.
