Things to watch (15)
From the version posted Oct 22, 2026.
- Serious: Set-aside: HUBZone or SDVOSB businesses only. Firms that are not HUBZone or service-disabled veteran-owned small businesses cannot bid.
- Serious: Offer guarantee and performance and payment bonds. The documents tie an offer guarantee and bonds to the Seed Project price (estimated at more than $10,000,000); the form shows 10 calendar days after award for bonds. The form's yes/no boxes couldn't be read, so check the form on SAM.gov.
- Worth checking: SAM.gov set-aside field differs from the documents. SAM.gov says the set-aside is not stated, while the documents say HUBZone or SDVOSB; the cover form says HUBZone AND SDVOSB and Section C says HUBZone or SDVOSB. Ask the contracting officer to confirm.
Show all 15Show fewer
- Worth checking: Funds not presently available. No award will be made until funds are available, and the Government can cancel before or after the closing date without paying proposal costs.
- Worth checking: Past performance must be in the Southeast Region. Only projects in SBA Region IV states count; a bidder whose experience is elsewhere is rated Not Relevant on past performance.
- Worth checking: Must respond to 75% of task order requests. Awardees who skip too many task order proposal requests (TOPRs) can be removed from the contract, so winning means committing staff to ongoing proposal writing.
- Worth checking: Task order site visits expected to be required. Site visits for task orders are required unless a task order says otherwise, and skipping one can make that proposal non-responsive.
- Worth checking: Task order proposals are unpaid. Proposal costs are the contractor's, and proposals may be requested before funding exists, with no pay if the task order is never funded.
- Worth checking: Minimum guarantee is only a $3,000 orientation task order. Each awardee is guaranteed just a $3,000 Post-Award Orientation task order; any other work depends on winning task orders.
- Worth checking: Teaming and limits on subcontracting. Joint ventures must follow SBA rules, and the limitations on subcontracting clause (which caps how much of the work a set-aside winner may pay other firms to do) applies.
- Minor: DoD SAFE access must be requested first. Proposals go only through DoD SAFE, and each access grant lasts fourteen days, so request access in time to upload.
- Minor: Response due date moved by amendments. Amendment 0004 moves the response due date from October 28, 2026 to November 2, 2026, 12:00 PM ET; earlier documents show other dates, so use the latest.
- Minor: The site visit was Aug 6, 2026. Check the notice and its amendments for whether attendance was required, and whether another visit is offered.
- Minor: Recent past performance wording differs. Section M counts a project as recent if one day of performance fell within five years of the solicitation's release; Amendment 0001 says projects must be completed within the past five years. Ask which governs.
- Minor: Progressive Design Build task orders may be competed elsewhere. Statement of Work Rev 01 adds Progressive Design Build, where the Government can decline the construction phase if a fair price is not agreed and compete it across the MACC pool.
