ITEM 1 - DESCRIPTION OF WORK

1.1 Background: Fort Scott National Historic Site, located in Fort Scott, Kansas, is a significant historical landmark that preserves the legacy of the U.S. Army's role in the westward expansion of the United States during the 19th century. Established in 1842, the fort played a crucial role in various military campaigns and served as a base for operations during the Mexican American War and the Civil War. The site features a collection of historic buildings, including barracks, officers' quarters, and a hospital, which collectively represent the architectural and cultural heritage of the period. The roofs slopes vary from 12 x 7 ½ to 12 x 8.

1.2 Work Covered by the Contract Documents:

A. Project Location: 1 Old Fort Boulevard, Fort Scott, Kansas 66701

B. Work consists of: The re-pointing of the exterior exposed brick chimneys on the following buildings of the Fort Scott National Historic Site; HS-1, 2, 4, 5, 6, 7, 8, 11, & 12. HS-11 & 12 have a single chimney on each building, while all of the others have two chimneys each.

Sixteen chimneys in total, mostly on two- and three-story historic structures.

The contractor will cut to remove the extremely hard mortar, in order to save the extremely soft bricks. Existing bricks were manufactured by Acme Brick Company (see www.brick.com for contact, locations, and brick product). All replacement brick shall be by Acme Brick Company or approved equivalent manufacturer with product matching existing chimney brick.

Contractor to review existing brick on site in making determination of suitable proposed sample product line(s). The contractor shall provide manufacturer produced sample boards (12”x16” minimum size sample board) representing the full color and texture range of the proposed brick to the COR for review and written approval prior to procuring the product.

They will remove the existing lightening suppression equipment and re-install. They will remove the existing crowns and replace them “in-kind,” size, shape, and color. They will remove the counter flashing that is ‘tucked’ into the mortar and replace it with new galvanized counter flashing, fastening it in the same fashion as existing. Step flashing beneath counter flashing is assumed to be in satisfactory condition and not called for replacement. If the step flashing, once revealed from removal of counter flashing, is not in acceptable condition, stop work and notify COR for written determination of the manner to proceed. The Contractor shall photo document condition of step flashing at all faces of all chimneys and submit to the COR before covering up with new counter flashing. All counter flashing shall be stainless steel complying with ASTM A 240, Type 304 with minimum thickness 0.01-inch.

If damage is done to cedar shingles, shingles will need to be replaced with in-kind material.

Where shingles are damaged or require removal, the Contractor shall reinstall or replace with like shingle material without compromise to the roof’s water tightness. As government furnished material, the Contractor shall be allowed to use back stock shingle material stored http://www.brick.com/

Page | 4 at the park at no cost. Total coverage available for use is 1000 square feet which is expected to greatly exceed the potential total quantity required due to damage from re-flashing work.

The Contractor shall be responsible for procuring any additional quantities greater than government furnished shingle quantity should site damage during construction require additional replacements. Existing shingles are Certi-Wood Blue Label fire resistant wood shingle. All Contractor provided shingles, should extent of construction damage exceed government furnished quantity shall be of the same manufacturer or COR approved equivalent. Leaks identified as originating from the improper replacement of shingles shall be considered applicable within the one-year warranty to provide repair to damage incurred.

Cracked bricks will be replace with new of same size and color, not to be softer than the existing ones. The new mortar will match existing in color and hardness. The contractor will also apply a sealer to the new exterior surfaces. Buildings HS-05 and HS-06 chimneys will need to be inspected and repaired to ensure full functionality. Chimneys on HS 1, 2, 4, 7, 8, 11, 12 will need to be capped/closed off if not already capped.
