DIVISION 1 SHORT FORM GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The George Stanford House is significant for its long association with a prominent

Boston Township family. Its associated outbuildings and rural environment illustrate Boston

Township’s agricultural heritage and preserve, intact, a fine nineteenth-century farm in the

Cuyahoga Valley. The Goia Main House serves as the main office for the park partner

Conservancy for Cuyahoga Valley National Park. In order to preserve these historic assets, the aging and failing roof systems and associated components must be replaced. The current roofs exhibit material failure, cedar shingles are severely decayed and broken or missing in numerous locations. Asphalt shingles are worn, cracked, and missing in locations. Gutters are rusted through, misshapen, or missing. Continued deterioration will lead to failure and leaking, potentially resulting in structural damage and mold. This will pose a risk to the health and safety of visitors of the farm, overnight guests of the house, and to the Conservancy staff. This roofing project will extend the asset life cycle and reduces service-wide maintenance backlog, as well as preserve important cultural resources.

1.2 Work Covered by the Contract Documents:

A. Project Location: George Stanford House, 6093 Stanford Road, Peninsula, OH 44264 and

Goia House (Hines Hill Campus), 1403 West Hines Hill Road, Peninsula, OH 44264

B. Work consists of: This project will replace the roof and gutters on three structures of the historic George Stanford Farm. The cedar shingle roofs of the house, and smoke house will be replaced with new cedar shingles laid over new skip sheathing to resist moisture entrapment. The asphalt shingle roofs of the garage will be replaced with new asphalt shingles. At the Goia House the roof will be replaced with new asphalt shingles. Roof work will also include removal and replacement of damaged sheathing and wood fascia trim, and the installation of new metal flashing, drip edge, gutters, and downspouts. This project will replace approximately: 2,650 square feet of cedar shingles, 6,110 square feet of asphalt shingles, 320 square feet of EPDM roofing, and 740 lineal feet of gutters and downspouts.

Significant improvements will be made to the moisture protection of 3 important historic structures and the Goia Main House. The longevity of the new cedar shingles will be greatly increased by the installation of skip sheathing, which will allow the shingles to dry through improved ventilation.
