About this file
This document provides construction specifications for a roof replacement project. The specifications call for installing a new EPDM single-ply membrane roofing system using Genflex or equivalent sheet material along with associated flashing, stripping and accessories. The project scope includes removing the existing roofing system down to the decking and installing a new vapor barrier and insulation prior to installing the new roof membrane. The specifications provide details on installation requirements, manufacturer warranties, and experience qualifications for the roofing contractor. Relevant details include requirements for the roofing membrane thickness, fastening patterns, flashing details, and jointing. The contractor will be required to warrant the entire roofing system to be watertight for a period of 15 years.
This project is being solicited by the Department of the Interior US Geological Survey under solicitation number 140G0221R0013 for a roof replacement at their facility. Offerors should reference the provided construction specifications and details when preparing proposals for this project.
