The National Park Service (Interior Department, DSC Contracting Services Division) wants a prime contractor for solicitation 140P2026R0081 to stabilize the Kingsley Plantation shoreline with a seawall extension at Timucuan Ecological and Historic Preserve, Jacksonville, Florida. The response due date is November 13, 2026, 5:00 PM Eastern, after Amendment 0003 extended it. The contract duration is 259 days, in three phases that must follow one another, with a magnitude of construction stated as $1,000,000 to $5,000,000.
Who can bid
- Small business under NAICS 237990 (size standard $45M); the solicitation form says the acquisition is a small business set-aside
- Bid guarantee with the offer: SF 24 Bid Bond or other suitable bid guarantee
- Key trades and key personnel with sheet pile driving experience (steel, vinyl or FRP); a quality control (QC) manager, a site safety and health officer (SSHO) and a superintendent are named positions
Things to watch (11)
- Serious: Set-aside differs between SAM.gov and the solicitation. SAM.gov does not state a set-aside, but the solicitation form says this is a small business set-aside; check with the contracting officer which governs.
- Serious: Bid guarantee and bonds. A bid bond or other guarantee goes in with the offer, and performance and payment bonds follow award; the amounts were in parts of the solicitation not read.
- Worth checking: Phases must run one after another. No overlapping crews or phases are allowed, which limits how a bidder can shorten the 259 days.

- Worth checking: Obstructions during pile driving are the bidder's risk. Pre-augering and jetting are prohibited for vinyl/FRP piles, and bidders must price a contingency for refusal on unexpected obstructions.
- Worth checking: Low-tide, daylight-only shoreline work. Shoreline pile driving, riprap and plantings only happen at low tide, in daylight, with a limit of 5 synthetic sheet piles per day, and no tree cutting during bat pup season.
- Worth checking: Permit still in process. The St. Johns River Water Management District permit is not finished; its conditions will be shared when available and could affect pricing.
- Minor: 730-day plant warranty after completion. Spartina plantings carry a 730-day warranty period with no retainage; the government can call for replacement plants.
- Minor: Work hours and delivery days limited. Work runs 8am to 5pm Monday to Friday per the answers; the division 01 specification says 8:00 a.m. to 4:30 p.m., so ask which hours govern. Large deliveries are limited to Monday and Tuesday.
- Minor: Response due date moved to November 13, 2026. Amendment 0003 extended the response due date; the original form showed 11/06/2026 at 1700, and the earlier answers refer to a November 6 deadline.
- 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: Florida contractor license not confirmed. The government did not say if a Florida general or marine contractor license or county registration is needed; bidders must check with the state.
