Scope of Work

Bodie Island Lighthouse Paint Watch Gallery Deck Project

1.0 INTRODUCTION

The National Park Service (NPS) Cape Hatteras National Seashore (CAHA) has a requirement to paint the exterior wall of the Watch Gallery including its decking and railings.

Site location: Bodie Island Lighthouse; 8210 Bodie Island Lighthouse Road, Nags Head, NC.

27959.

BACKGROUND AND EXISTING CONDITIONS

The Bodie Island Lighthouse is on the National Register of Historic Places and was erected in 1872. The Bodie Island Lighthouse (BILH) is operational and is used for nautical navigation.

The lighthouse has an interesting past as it was rebuilt two times after natural and man caused events, the lighthouse as it stands today represents the third structure. The lighthouse rises 162 feet from the water elevation, has ten (10) levels, and is constructed primarily of brick and cast-iron stairs, Watch Gallery decking and supports and Lantern room.

The Bodie Island Lighthouse (BILH) came under the management of the National Park Service on July 13, 2000 when it was transferred from the US Coast Guard (USCG).

The Lighthouse was painted in 2012, however the Watch Gallery paint has been touched up over the past eight years resulting in mismatched coloring and paint chipping. The railing is approximately 80 linear feet and 4 feet high along the outside edge of the Watch Gallery platform. The decking and level 9 exterior wall to be painted is approximately 688 SQFT.

The BILH has a spiral staircase with eight landings. The string of steps between each landing is either anchored to the lighthouse wall and / or suspended between each landing. Because of the age and design of the staircases, only one person can be on any one string of stairs at one time.

The interior of the lighthouse can vary in temperatures and humidity through-out the day and reach temperatures above 100 degrees. The Watch Gallery experiences sustained winds of 15 mph with multiple days above 20 MPH and higher speed gusts regularly.

The contractor is required to verify existing conditions, dimensions.
