This is a comprehensive roof replacement project for four specific buildings at the PPPL laboratory, where existing roofs are failing and causing water infiltration. The subcontractor must provide all labor, materials, and equipment to fully remove and replace the built-up roof systems, including all related components like insulation, flashing, drains, and copings. The new roof system must use specified Carlisle Syntec materials to achieve a 30-year manufacturer's warranty and meet an R-30 insulation value. The work includes managing asbestos abatement coordination, temporary equipment relocation, and installing new safety features like guardrails. The project is critical to prevent a catastrophic roof failure that would disrupt top-priority experimental operations at the laboratory.
