Things to watch (12)
- Serious: Small business set-aside. Only small businesses can win this construction job; the size standard is $45M in average annual receipts.
- Serious: Bid bond required with the offer. You must send a Standard Form 24 bid bond or other suitable guarantee with Volume II, and the contract includes a performance and payment bonds clause, so you need a surety.
- Worth checking: Set-aside shown in the solicitation but not on SAM.gov. SAM.gov does not state a set-aside, while the solicitation says small business set-aside; confirm with the contracting officer before relying on either.
Show all 12Show fewer
- Worth checking: More amendments expected; permits not final. Natural resource protection requirements (Appendix C) will come in the next amendment, and the St. Johns River Water Management District permit is still in process.
- Worth checking: Three phases must run one after another. Each phase must be substantially complete before the next starts, and overlapping crews are not allowed, which limits how fast you can finish.
- Worth checking: Pile obstructions are on the contractor's price. Pre-augering and jetting are not allowed for the vinyl and FRP piles, so you must carry a contingency in your price for obstructions.
- Worth checking: Gopher tortoise permit and relocation are the contractor's job. You must get the permit and move the tortoises at your own cost and schedule risk, with burrows shown on drawing C1.4.
- Worth checking: Limits on subcontracting. A subcontracting percentage worksheet is required with the offer, and a limitations on subcontracting clause (FAR 52.219-14) is in the contract, so check how much you can hand to subcontractors.
- Minor: The site visit was Oct 20, 2026. Check the notice and its amendments for whether attendance was required, and whether another visit is offered.
- Minor: Work hours and delivery days are restricted. Amendment 0002 gives work hours of 8am to 5pm Monday to Friday with no weekend work, and large deliveries are unlikely to be approved outside Monday and Tuesday, when the park is closed.
- Minor: Two-year plant establishment as a warranty. Spartina plantings carry a 730-day warranty, with no retainage or extra bonding, so you may have to replace dead plants after finishing.
- Minor: Florida license question left to the bidder. NPS did not say whether a Florida contractor license is required, so check with the state before bidding.
