FORT FREDERICA NATIONAL MONUMENT

FLAGPOLE RESTORATION AND BEAUTIFICATION

NATIONAL PARK SERVICE (NPS)

1.0 BACKGROUND

Fort Frederica National Monument (FOFR) preserves significant 18th-century cultural resources and provides visitor services within a historically sensitive landscape setting. The flagpole area near the Visitor Center is a focal point for visitor arrival and interpretation. Address: 6515 Frederica Rd. St. Simon Island, GA 31522.

Existing conditions include deteriorated coating on the steel flagpole, limited nighttime visibility of the flag, aging pedestrian surfaces, and a lack of coordinated site furnishings in the area.

This project improves the functionality and visual integration of the flagpole area while maintaining compatibility with the historic character of the Visitor Center setting.

Project objectives include:

• Installing lighting to allow the flag to be flown in accordance with flag display practices during evening hours

• Rehabilitating the flagpole to prevent corrosion and extend service life

• Constructing a Faux Tabby Finish concrete sidewalk surface that reflects the existing materials and character of the Visitor Center site

• Providing a brick-clad pedestal that visually anchors the flagpole while remaining non-structural

• Installing benches to improve visitor comfort and site use

2.0 SCOPE OF WORK

The Contractor shall provide all labor, supervision, materials, equipment, tools, transportation, and incidentals necessary to complete the following work at the FOFR flagpole area:

• Perform surface preparation and full coating rehabilitation of the existing steel flagpole

• Provide underground electrical service from the Visitor Center to the flagpole area

• Install lighting, transformer, controls, pedestal, and associated conduit systems

• Construct new concrete walkway areas with Faux Tabby Finish

• Construct a framed and brick-clad architectural pedestal around the existing flagpole footing

• Furnish and install two exterior benches

Work includes coordination of construction sequencing to protect new and existing site features and to prevent conflicts between trades.
