Description
The West Virginia Division of Corrections and Rehabilitation is seeking bids for a roof replacement project at the South Central Regional Jail. The project involves removing and replacing the existing roof system, including the roof membrane, flashings, coping, counter-flashings, and insulation, and installing a new 2-ply modified bitumen roof system. The contractor will also be responsible for raising curbs, plumbing stacks, utility lines, gas lines, and equipment supports to provide sufficient flashing height to meet manufacturer's requirements and accommodate new insulation thickness. The project requires the contractor to employ certified mechanical and electrical contractors to remove and reinstall mechanical equipment and recharge systems, and to disconnect and reconnect power lines and devices. The contractor must also maintain water tightness and provide protection at any openings in the roof left at the end of each construction day.
Key aspects of the project include:
• Removing and salvaging river rock ballast for owner's reuse
• Removing and discarding existing roof system, including roof membrane, flashings, coping, counter-flashings, and insulation
• Installing tapered insulation system with R-30 average achieving a minimum slope of 1/8:12 on flood/gravel roof sections
• Installing modified bitumen base and cap sheets in cold adhesive throughout the field
• Applying coal-tar flood coat and embedding aggregate on all roof sections, except the gym roof
• Installing new shop-fabricated counterflashings, metal coping, scuppers, and downspouts in the owner's choice of color
