CASA 324271, Castillo de San Marco National Monument, Repair and Raise Seawall

The National Park Service, a bureau of the Department of the Interior, is seeking construction services for the repair and raising of the seawall at Castillo de San Marcos National Monument in St. Augustine, Florida. The project encompasses the reconstruction of approximately 1,355 linear feet of seawall, including the demolition and construction of four new seawalls (three sheet pile walls with stacked granite facade and one sheet pile wall), rehabilitation of the existing Center Seawall, and associated site improvements such as a new entrance plaza, reconstructed walkways, infrastructure replacement, and reinforced turf installation. The contract will be evaluated based on technical merit, past performance, and price, with award being made to the responsible offeror providing the best value to the government. The Request for Proposal is expected to be released on or about December 8, 2025, via SAM.gov, with a proposal due date of January 8, 2026. Bid, performance, and payment bonds will be required for this project.

This procurement is designated as a Total Small Business set-aside, with a $45 million size standard applicable to small business contractors. The contract will be awarded as a Firm-Fixed-Price agreement with an anticipated performance period of 550 calendar days. While no incumbent contractor information is provided in the pre-solicitation notice, the estimated project value is approximately $45 million, indicating a significant capital investment in the monument's coastal infrastructure. The project is classified under NAICS Code 237990 (Heavy and Civil Engineering Construction) and PSC Code Y1PZ (Construction of Other Non-Building Facilities), reflecting the specialized nature of marine and civil engineering work required for this seawall reconstruction initiative.
