This is a detailed project specification document for the Northwestern Regional Adult Detention Center, a Virginia state facility, outlining the replacement of membrane roofing. The project involves the replacement of approximately 88,000 square feet of existing Carlisle 0.060 EPDM (ethylene propylene diene monomer) ballasted membrane roofing with a like product. The specification document details comprehensive requirements for the roofing system, including materials, installation methods, quality standards, and workmanship expectations. The project scope encompasses roof preparation, removal of existing ballast, installation of new membrane material, replacement of ballast, and associated repairs to roof penetrations and flashing. The specification emphasizes compliance with manufacturer requirements and industry standards, with particular attention to proper installation techniques for ballasted roof systems in accordance with Carlisle specifications and ASTM standards.

The project specification requires bidders to provide detailed pricing for labor, materials, equipment, and all associated costs necessary for complete project execution. The document specifies performance and warranty requirements, including adherence to single-ply membrane installation standards and manufacturer-backed warranties for workmanship and materials. Bidders must demonstrate experience with similar ballasted roof replacement projects and provide evidence of technical competency. The specification includes provisions for project site conditions, weather-related work restrictions, and coordination with facility operations at the active detention center, requiring contractors to maintain appropriate security protocols and minimize disruptions to facility operations. All work must be completed in accordance with applicable Virginia building codes and local regulations governing the detention center facility.
