Timucuan Ecological and Historic Preserve TIMU-335507 Stabilize Kingsley Plan

The National Park Service is preparing to procure construction services to stabilize and extend the shoreline seawall at Kingsley Plantation within Timucuan Ecological and Historic Preserve in Jacksonville, Florida, with a competitive Request for Proposals anticipated in Summer 2026. This is a sources-sought market research phase, and the survey questionnaire closes on June 22, 2026.

The estimated construction magnitude ranges from $1,000,000 to $5,000,000, with an anticipated period of performance of 259 calendar days. NPS intends to award a single Firm-Fixed-Price contract. No set-aside is currently anticipated, though the level of contractor interest will inform whether a small business or socio-economic set-aside will be applied to the eventual solicitation. NAICS 237990 (Other Heavy and Civil Engineering Construction) applies, with a size standard of $45.0 million.

The project involves repairing storm damage from Hurricane Ian and extending the existing seawall to enhance future storm resiliency while protecting cultural and ecological resources across the preserve's 46,000 acres and 6,000 years of human history. Bid, Performance, and Payment Bonds are anticipated to be required. Respondents must demonstrate prime contractor experience with federal construction contracts of similar scope and magnitude, specifically seawall installation in coastal Florida using driven sheet pile walls and limestone riprap. Contractors must also show compliance capability with Florida local construction building licensing and permitting requirements and disclose bonding capacity.

Unique project constraints include limited delivery windows (Monday and Tuesday only, with case-by-case approval for other days) and minimization of visitor impact while the park remains open. Responses to the survey questionnaire should be submitted to joseph_wingfield@ios.doi.gov by 5:00 PM ET on June 22, 2026.
