CASA 324271, Raise and Repair the Seawall at the Castillo De San Marcos Nationa

The National Park Service Denver Service Center has issued a Sources Sought Notice for a major seawall reconstruction project at the Castillo de San Marcos National Monument in St. Augustine, Florida. The project involves reconstructing approximately 1,355 linear feet of seawall across five distinct segments: North Wall, North Transition Wall, Center Wall, South Wall, and South Transition Wall. The work includes demolition and construction of four new seawalls with sheet pile and stacked granite facade, rehabilitation of the existing center seawall, construction of new walkways, and replacement of utility infrastructure. The estimated construction value exceeds $10 million with a 550-calendar day performance period. The project falls under NAICS code 237990 (Other Heavy and Civil Engineering Construction) with a $45.0 million size standard.

The purpose of this Sources Sought Notice is to conduct market research to determine the appropriate solicitation method and assess potential small business set-aside opportunities for the upcoming competitive procurement. Interested contractors must complete and submit a detailed Sources Sought Survey Questionnaire by 4:00 PM Mountain Time on August 1, 2025, to joseph_wingfield@nps.gov. The survey requires information about company capabilities, federal construction experience, local licensing, bonding capacity, seawall installation expertise, and small business certifications. The National Park Service anticipates releasing a competitive Request for Proposals in Fall 2025 for a single Firm-Fixed-Price contract. Contractors should be prepared for bonding requirements including Bid, Performance, and Payment bonds, and must consider that construction will occur in an urban setting with the park remaining open to visitors during the work period.
