This document is a set of contract drawings and exhibits for a roof replacement project at Stevens Correctional Center and Jail in Welch, West Virginia, prepared for the West Virginia Division of Corrections and Rehabilitation under ARFQ 0608 DCR2600000097. The project scope includes removal and replacement of existing roof systems across multiple sections of the facility (Sections A through M) with a 2-ply modified bitumen roof system. Work includes removal of existing roof membrane, rock ballast, flashings, coping, and insulation down to the metal and concrete decking; installation of tapered insulation systems achieving R-30 average with minimum 1/4:12 slope; installation of 1/2-inch gypsum coverboard; installation of modified bitumen base and cap sheets with cold adhesive; installation of new flashings, metal coping, scuppers, and downspouts; application of coal-tar flood coat with aggregate surfacing; and provision of manufacturer warranty upon completion. The drawings include overall campus roof plans, detailed flashing specifications for various penetrations and conditions (drains, stacks, vents, equipment supports, hatches, through-wall penetrations), and roof plan sections with specific dimensions and locations of work.

The roofing contractor is responsible for field verification of all existing conditions, dimensions, and quantities prior to commencement of work; maintaining water tightness throughout construction; protecting adjacent surfaces and repairing any damage at no additional cost to the owner; coordinating work with other trades; employing certified mechanical and electrical contractors for equipment disconnection and reconnection with system testing and certification; raising all curbs and equipment to meet manufacturer flashing requirements; installing fall protection barriers around rooftop units as specified; and verifying that all roof drains and drain piping are clear and unplugged at project completion with camera scoping of drain lines. The document specifies adhesive application patterns varying by zone (12-inch, 6-inch, or 4-inch on-center spacing depending on uplift zones), three-course mastic application to vertical flashing seams with aluminized reflective coating, and compliance with FM approvals confirmed through Garland Engineering Services.
