SCOPE OF WORK

CARL PMIS #344715

Repair Maintenance Shed

Carl Sandburg Home National Historic Site

PROJECT LOCATION

Carl Sandburg Home National Historic Site, Henderson County, Flat Rock, North Carolina 28731

OVERVIEW

On September 28th, the equipment storage shed sustained significant damage due to Hurricane Helene.

Two large trees fell through the roof of the building, completely cutting through the entire roof structure resulting in damage to three garage bay doors, electrical wiring, and causing substantial structural damage to the asphalt shingle roof. The trees have been removed but some debris and all damage to the structure remain and now this project will replace the entire roof and repair the remaining damaged areas of the shed.

The shed was constructed in 1985 to support park operations as part of the maintenance yard complex.

The shed provides storage space for vehicles and materials out of the elements, but the structure is not a conditioned space. The overall dimensions of the building are 146-feet long by 25-feet wide by 18-feet high and the wood framed structure sits on a concrete slab.

This contract encompasses the removal and replacement of approximately 4500 square feet of asphalt architectural 30-year shingles and #30 underlayment. It includes the repair or replacement of damaged plywood sheeting, flashing, and drip edge, as well as the installation of roof underlayment. Additionally, the contract covers the removal and replacement of approximately 150 linear feet of gutter with downspouts and the installation of approximately 150 linear feet of gutter guards on the maintenance equipment storage shed. Furthermore, this contract will address the repair of three commercial garage bay doors, including hardware, and the restoration of all wiring damaged by fallen trees.

Helene. The work includes three main areas:

• Complete replacement of the asphalt shingle roof and gutters
