Lake Barkley Resource Manager's Office & Visitor Center Roof Replacement

This is a Solicitation notice for the Lake Barkley Resource Manager's Office and Visitor Center Roof Replacement.

Located at 200 Barkley Dam Overlook Drive, Grand Rivers, KY 42045, the Lake Barkley Resource Manager's Office and Visitor Center Roof Replacement project is described as follows:

The existing building consists of three sections: a cedar-sided, hip-roof framed (3:12 slope) multi-slope center portion that is currently covered by asphalt shingles (approx. 4000 sq. ft.); and two lower level wings (north, 945 sq. ft.; and south, 1,009 sq. ft.) of cast-in-place concrete construction with flat roofs of varying composition.

The existing sloped roofs shall have all roofing material removed to the bare plywood sheathing. Any sheathing found to be in unsound condition shall be removed and replaced in kind.

The existing flat roof areas shall have all roofing material removed to the bare gypsum-concrete deck. On the north wing, a portion of the cast-in-place concrete parapet wall that rises to form the railing of the ramp to the observation deck shall be saw-cut and demolished to an elevation level with the top of the parapet. The existing roof mounted exhaust fans shall be removed from the south wing and the roof openings prepared to receive new exhaust ductwork.

Remove existing roof drains and cap drain lines. Any additional roof mounted items on the two flat-roofed wings shall be removed or relocated. All wood in contact with concrete or masonry shall be pressure treated. Provide and install prefabricated single sloped roof trusses on both north and south wings. Truss design shall be by a professional engineer licensed in the state of Kentucky and experienced in the design and fabrication of prefabricated wood trusses.

Provide and install new end-wall framing and sheathing. Provide and install new roof underlayment over the entire building's roof surface. Provide and install standing seam aluminum roofing and associated trim and flashing over the entire building's roof surface. Panels shall be warranted for not less than twenty (20) years. Provide and install gutters and downspouts of material matching the roof panels.

Provide and install blown-in cellulose loose fill insulation over a 6-mil polyethylene vapor barrier sufficient to achieve an R-50 rating. Fabricate and install access doors into attic areas above both wings.

Provide and install new ductwork, in-line exhaust fans, exhaust louvers, and all associated electrical wiring and controls to extend existing ductwork to the east end-wall of the south wing. New exhaust system final design shall be performed by a professional mechanical engineer licensed in the state of Kentucky. Final exhaust system design shall be submitted for approval.

A guided site visit has been arranged to aid in preparation of offerors' bids for 17 Aug 2017, 1:00 to 3:00 PM (Central Daylight Time). Participants will meet in the Lake Barkley Resource Manager's Conference Room. The Visitor Center telephone is (270) 362-4236.
