Who can bid
- For a small business reserve award: HUBZone, women-owned (WOSB), service-disabled veteran-owned (SDVOSB) or 8(a) status, small under NAICS 236220 ($45 million size standard)
- Small business reserve bonding capacity: at least $3 million single project and $10 million aggregate
- Unrestricted award bonding capacity: at least $100 million single project and $300 million aggregate
Things to watch (5)
- Serious: Small business reserves need a program status. About 16 of the 20 awards are reserved for HUBZone, WOSB, SDVOSB and 8(a) firms, about four per category; other small firms would compete for the unrestricted awards.
- Serious: Bonding capacity required. Reserve offerors need surety proof of $3 million single and $10 million aggregate; unrestricted offerors need $100 million and $300 million.
- Worth checking: Seed project site visit November 9, 2026. Two sessions are planned; offerors are urged and expected to attend, which means strongly encouraged, and may attend only one session.

- Worth checking: Low guaranteed minimum. Each award guarantees only $1,000, so winning a MACC slot doesn't guarantee meaningful work.
- Worth checking: Pricing a seed project. The source selection uses a seed project, so bidders likely must price a real construction job as part of the proposal.
