Y--Timucuan Ecological and Historic Preserve TIMU-335

This pre-solicitation notice announces that the National Park Service (NPS) Denver Service Center plans to issue Request for Proposal (RFP) 140P2026R0081 for shoreline stabilization construction services at the Timucuan Ecological and Historic Preserve in Jacksonville, Florida. The project, titled "Stabilize Kingsley Plantation Shoreline with Seawall Extension," involves selective demolition, installing a new weatherable rigid vinyl sheet pile wall with tie rods and a deadman wall, extending the wall with a structural FRP composite sheet pile wall, and conducting associated civil works such as excavation, backfilling, sodding, spartina sea grass restoration, and limestone riprap installation. Classified under NAICS code 237990 (Other Heavy and Civil Engineering Construction) with a $45 million size standard, this procurement is a total Small Business Set-Aside. The project's estimated magnitude of construction is between $1,000,000 and $5,000,000, with an anticipated performance period of 259 calendar days from the Notice to Proceed. The contract will be a Firm-Fixed-Price vehicle awarded via a best-value trade-off process, where technical and past performance factors are significantly more important than price. Bid, performance, and payment bonds are required. The formal solicitation is expected to be released on or about October 2, 2026, on SAM.gov, with a pre-proposal conference and site visit to be scheduled thereafter. Prospective offerors must have an active SAM.gov registration and a Unique Entity ID (UEI) to participate.

The National Park Service (NPS) Denver Service Center has issued a Sources Sought Notice (SSN) for market research to stabilize the Kingsley Plantation Shoreline at Timucuan Ecological and Historic Preserve in Jacksonville, FL. The project, with an estimated construction cost between $1,000,000 and $5,000,000, involves repairing existing seawall damage caused by Hurricane Ian and extending it to enhance future storm resiliency and protect cultural and ecological resources. The NPS anticipates a competitive acquisition, possibly with a small business set-aside, and plans to issue a Request for Proposals (RFP) around Summer 2026 for a single Firm-Fixed-Price (FFP) contract. The project requires Bid, Performance, and Payment Bonds and falls under NAICS code 237990 with a $45.0M size standard. Responses, requested from both large and small businesses, must be submitted via an attached questionnaire by 5:00 PM ET on June 22, 2026.

The Department of the Interior, National Park Service, Denver Service Center, is issuing a Sources Sought Notice (Solicitation No. 140P2026R0081) to gauge interest and determine the appropriate solicitation method for a construction project (NAICS 237990).

This federal solicitation (No. 140P2026R0081), issued by the National Park Service (NPS) Denver Service Center, is a total small business set-aside for a firm-fixed-price construction project to stabilize the Kingsley Plantation shoreline at the Timucuan Ecological and Historic Preserve in Jacksonville, Florida. The estimated magnitude of construction is between $1,000,000 and $5,000,000, with a performance period of 259 calendar days after the contractor receives the notice to proceed. The scope of work entails selective demolition and civil engineering tasks, including the installation of a new weatherable rigid vinyl sheet pile wall with tie rods and a deadman wall directly in front of the existing PVC sheet pile wall. Additionally, the contractor will extend the wall to the east using a structural fiber-reinforced polymer (FRP) composite sheet pile wall. Other required civil works include excavation, soil and gravel backfilling, sodding, spartina sea grass ecological restoration, and the installation of limestone riprap in front of the wall. Key administrative requirements include a 15% self-performance minimum by the prime contractor, a $1,363.00 daily liquidated damages rate for completion delays, and the submission of performance and payment bonds. Invoices must be processed electronically through the Department of the Treasury's Invoice Processing Platform (IPP) and accompanied by weekly progress schedules and subcontractor payment certifications.

The project addresses damage from Hurricane Ian by replacing and raising the existing seawall by 18 inches, which requires in-water work and selective demolition. Key technical specifications outlined in the file include: - **Selective Demolition (Section 02 41 19):** Covers the removal and salvage of site elements, protection of adjacent occupied areas, and strict handling of materials in non-historic versus historic zones. - **Hot-Dip Galvanizing (Section 05 05 13):** Specifies the requirements for zinc-coating structural steel, fasteners, and assemblies to prevent corrosion in marine environments. - **Structural Steel (Section 05 12 00):** Details the fabrication, assembly, and erection of steel tie rods, stainless steel plates, and turnbuckles used for waterfront structures. - **Protection of Buried Steel Bulkhead Tie Rods (Section 09 97 14):** Requires a petrolatum-based tape wrapping system and mastic primers to provide exterior corrosion protection for buried tie rods. - **Site Clearing (Section 31 10 00):** Establishes guidelines for clearing, grubbing, topsoil stockpiling, and the protection of undeveloped areas adjacent to a temporary construction haul road. The project mandates strict quality control, including certified technicians, pre-construction coordination, and field inspections to ensure structural integrity and environmental compliance.

This federal government project documentation details design drawings and engineering specifications for stabilizing the Kingsley Plantation shoreline, located within the Timucuan Ecological & Historical Preserve in Duval County, Florida. Prepared by AECOM on behalf of the National Park Service Denver Service Center, the project involves extending the existing seawall to prevent erosion and stabilize the historical site. The scope of work is divided into three construction phases and features the installation of a Polyvinyl Chloride (PVC) sheet pile wall with tie rods and deadman walls, alongside a Fiber Reinforced Polymer (FRP) composite cantilever sheet pile wall. Additional structural elements include importing soil backfill and placing limestone rock riprap. Demolition plans call for removing the top portion of the existing timber sheet piles, cutting and disposing of old tie rods, removing existing wood fencing, and salvaging specific horizontal timber facing boards for reuse. Contractor guidelines outline strict operational constraints, including a visitor-safety mandate limiting material deliveries to Mondays and Tuesdays when the park is closed. The plans designate specific contractor staging areas, trailer parking, and a temporary haul road designed to protect the surrounding environment. Notably, the contractor must preserve existing cedar trees and protect all local gopher tortoise burrows in compliance with Florida Fish and Wildlife Conservation Commission regulations. All work must adhere to the 2024 International Building Code, Florida Building Code, and USACE design standards.
