Statement of Work (SOW) FOMA Replace Nature Trail Boardwalk Riverside

National Park Service

1. Project Description: The National Park Service has a need to replace the existing nature trail/boardwalk structure with a new 1033 ft long by 6 ft wide elevated boardwalk, including three integrated seating areas equipped with benches and wayside exhibits. The project will enhance accessibility and safety while preserving the site's natural beauty and historical integrity. The current boardwalk has gone through numerous repairs this year due to rotted lumber. Several posts, joists, crossbeams have been replaced to keep the boardwalk open and accessible. The natural trail is located at the Fort Matanzas (FOMA), National Monument, 8635 A1A S, St. Augustine, FL 32080.

2. Conditions: Several components of the existing boardwalk—including posts, joists, crossbeams, and railings—have failed or continue to fail due to wood rot. As a result, the maintenance team must frequently perform repairs across the five boardwalks at Castillo de San Marcos and Fort Matanzas National Monuments. These ongoing repairs consume significant manpower and funding, and because the structures continue to deteriorate, long-term replacement projects are being planned over the next few years.

3. Standards: The contractor shall comply with all applicable standards to include, but not limited to the following:

a) Occupational Safety and Health Act (OSHA) 29 CFR 1910, 29 CFR 1904 Regulations (Standards -

29 CFR) | Occupational Safety and Health Administration (osha.gov)

b) NPS 2006 Management Policies, chapter 9 MP Ch 9: Park Facilities - Policy (U.S. National Park

Service) (nps.gov)

c) Florida Building Code Florida Building Code Online

d) International Code Council (ICC), International Building Standards – The ICC codes meet or exceed the requirements in the federal accessibility requirements found in the Americans with Disabilities Act. 2024 International Building Code (IBC)

4. Requirements: Contractor shall provide all labor, supervision, material, tools, equipment, supplies, transportation, and incidentals necessary to remove the old boardwalk, clear vegetation, and install a new boardwalk. Vegetation will be cleared no more than 24 inches on each side of the boardwalk and seating/exhibit areas. The new boardwalk must adhere to Architectural Barriers Act Accessibility Standard (ABAAS) compliance. The work breakdown is not all inclusive and other work may be required to achieve an acceptable level of workmanship for the boardwalk replacement. If additional work is required that is not included in this statement of work, you must address it during the open question period.
