These attachments contain technical documentation for a U.S. Army Corps of Engineers solicitation (W912WJ25QA040) for a PVC membrane roof replacement project at the New Bedford Hurricane Barrier in Massachusetts. The project involves comprehensive roof system replacement for a concrete building approximately 59 feet by 25 feet, with both lower and upper roof levels requiring complete demolition and replacement. The contractor must remove the existing roof system down to the concrete deck, including insulation, PVC material, walk pads, and associated components, and install a new fully adhered 60-mil thick PVC roofing system with tapered rigid insulation.

The solicitation is set aside exclusively for small businesses, with a NAICS code of 238160 and a small business size standard of $19 million. The project's construction magnitude is estimated between $100,000 and $250,000, with specific requirements including protecting existing roof-mounted equipment, designing for high wind coastal conditions, and obtaining a 30-year manufacturer warranty. Mandatory requirements include active SAM.gov registration, with vendors lacking this registration being automatically rejected. The new roof system must be watertight, properly pitched for water drainage, and include the careful relocation of existing roof infrastructure such as lightning protection systems, railings, cameras, lights, conduits, chimneys, and antennas.
