Cannonsburgh Village Haynes Museum Reroof – Scope of Work

The following scope describes the work to be completed to the Museum at Cannonsburgh Village owned by the City of Murfreesboro at 312 Front Street, Murfreesboro, TN 37133. The intent of this project is to replace the metal roof to prevent further interior damage to the facility and to allow the building to be reopened to the public.

The scope is as follows:

Demolition Work

1. Remove all existing Galvalume Roofing panels, underlayment, and rake boards at gable ends and dispose of them in accordance with state and local regulations from primary building roof and front porch structure.

Primary Building Roof Work

1. Inspect existing roof deck boards for deterioration. Remove and replace all existing wood roof decking boards that show evidence of deterioration. Assume the replacement of 560 SF of existing roof deck boards for bid proposal. Provide unit price for replacement of additional deck boards on a per square foot basis. New deck boards to be attached to existing roof trusses with 2 ring shank galvanized 10d nails or corrosion resistant 3” #10 wood screws at each truss/rafter location.

2. Install self-adhered roofing underlayment membrane per attached standing seam metal roof specifications.

3. Install 26 ga. Galvalume-wrapped 2x6 eave fascia aboard and eave vent system along both eaves. Eave vent to be Cor-A-Vent S-400 soffit strip vent or approved equal. Vent shall provide 10 square inches of free area per lineal foot.

4. Install new 26 ga. Galvalume gutter flashing and new 6” 26 ga. k-style galvalume gutters.

5. Install new 26 ga. Galvalume-wrapped gable end rake boards with edge flashing installed per roof manufacturer’s instructions.

6. Install new standing seam metal roof system per attached standing seam metal roof specifications.

7. Install 8 new 3”x4” corrugated 26 ga. Galvalume downspouts – 4 at each side of building.
