Things to watch (10)
- Serious: Set-aside: solicitation says small business, SAM.gov says not stated. The solicitation calls itself a Small Business Set-Aside while SAM.gov lists no set-aside. Only small businesses under the NAICS size standard can expect to be considered. Ask the contracting officer to confirm.
- Serious: Bid bond and performance and payment bonds. A bid guarantee must come with the offer, and the solicitation includes performance and payment bond clauses. A firm that cannot get bonded cannot compete.
- Worth checking: The site visit was Oct 20, 2026. Check the notice and its amendments for whether attendance was required, and whether another visit is offered.
Show all 10Show fewer
- Worth checking: Very specific past experience required. Project experience is judged on seawall projects in hurricane-prone areas at culturally significant, publicly open sites, and Factors 5 to 7 rank among the most important factors.
- Worth checking: Safety record is scored. You must submit three years of OSHA 300A logs and an insurer statement of your EMR; fewer incidents and a lower EMR rate more favorably.
- Worth checking: Limits on subcontracting. As a set-aside, clause 52.219-14 limits how much work you can subcontract, and a worksheet of projected subcontracting amounts must go in with the offer.
- Worth checking: Liquidated damages of $1,363.00 per day. If work is not completed on time, the contractor pays $1,363.00 for each calendar day of delay.
- Worth checking: Award possible without discussions. The Government intends to award on initial proposals, so the first proposal should carry your best price and terms.
- Minor: Work in three phases with delivery and hours limits. Each phase must be substantially complete before the next starts, material deliveries are planned on Mondays and Tuesdays, and on-site work is generally 8:00 a.m. to 4:30 p.m., Monday through Friday.
- Minor: Questionnaires cite a different solicitation number. The Project Experience and Past Performance forms show solicitation 140P2026R0016, while this solicitation is 140P2026R0081. Confirm with the contracting officer that these are the right forms.
