About this file
This document is Appendix C - Scope of Work for a roof replacement project for the Pueblo West Library, located at 298 S Joe Martinez Blvd. in Pueblo West, Colorado, under the jurisdiction of the Pueblo Regional Building Department. The project involves a comprehensive roof replacement for a single-story, 26,614 square foot public library building constructed in 1999, with two primary scope options: 1) a complete tear-off and replacement with a new PVC membrane roof system, and 2) a recover option using an EPDM membrane. The scope of work includes removing the existing single-ply TPO membrane roof installed in 2018, installing new vapor retarder, inspecting and replacing insulation, adding tapered crickets, installing cover board, and applying new membrane with detailed flashing at parapet walls, curbs, and penetrations. Additional work includes resetting mechanical equipment, replacing wall coping, and implementing comprehensive safety measures.
The project requires extensive site preparation, including setting up a construction yard, placing a dumpster, installing safety guard rails, and managing pedestrian traffic. The roof structure is a metal building with a steel frame and roof deck, featuring a low-slope design with a 1/4 inch per foot slope. The total roof area is approximately 157.1 square feet, with additional areas for parapet and wall flashing. While specific pricing is not detailed in the document, the scope suggests a comprehensive replacement approach that prioritizes warranty requirements, structural integrity, and adherence to manufacturers' installation instructions and OSHA safety standards. The project appears to be funded through local government resources, with a focus on maintaining the library's infrastructure and ensuring long-term roof performance.
