Show all 7Show fewer
- Bid guarantee (bid bond) of 20 percent of the bid price or $3 million, whichever is less, with the offer
- SAM.gov registration current before the response due date

- Joint ventures must include the joint venture agreement showing each member's identity, relationship, ownership and limits on authority
Things to watch (10)
From the version posted Oct 14, 2026.
- Serious: Only ISBEE small businesses can bid. The job is set aside for Indian Small Business Economic Enterprises that are also small under NAICS 236220; other firms cannot win.
- Serious: Bid bond due with the offer. A bid guarantee of 20 percent of the price or $3 million, whichever is less, must come with the offer; leaving it out may get the offer rejected.
- Worth checking: Joint venture and mentor-protege SBA proof. Joint ventures and teams must send SBA approval of small business status with the offer, or the offer may be rejected.
Show all 10Show fewer
- Worth checking: Navajo Nation licensing and employment rules. The site is on the Navajo Nation; the Government told bidders to contact its business licensing and employment offices, though the notice says TERO (Tribal Employment Rights Office rules) does not apply.
- Worth checking: At least 15 percent must be self-performed. The prime contractor must do 15 percent of the cost, not counting materials, with its own employees, and must send the J06 calculation sheet.
- Worth checking: Some questions still unanswered. Several Q&A answers are blank, and the Government may post more answers and updated attachments, which could change the price.
- Worth checking: Date passed (Sep 10, 2024): Final geotechnical report replaces the draft. The draft soils report in the basis of design was posted by mistake; price the work from the final report dated September 10, 2024, which calls for chemical treatment of reused soil.
- Worth checking: Solar canopy is a delegated design. The covered parking is a solar canopy designed by its manufacturer, with panels and inverter, so a small builder needs a canopy supplier.
- Minor: Response due date moved by Amendment A04. Amendment A04 extends the response due date to November 12, 2026, from October 22, 2026 set by Amendment A03.
- Minor: Limited work hours at an occupied site. Site work is limited to set hours, the owner stays in the adjacent rooms, and the Contracting Officer must approve extra costs for work outside those hours.
