This document is a roof plan for Operating House #1 in New Bedford, detailing a roof replacement project. The architectural drawing shows a 59'-0" x 25'-0" building with both lower and upper roofs to be replaced with a new PVC membrane roofing system. Key elements include existing ventilators, chimneys, antennas, and roof equipment that will remain or be carefully relocated during the renovation. The plan indicates specifics such as slope requirements (1/4" per foot minimum), new roof membrane installation, and preservation of existing roof railings, conduits, and other infrastructure.

The roof replacement involves removing the entire existing roof system down to the concrete deck, including insulation, PVC material, walk pads, and flashings. The new roof will feature 60-mil PVC roofing designed for high wind coastal conditions, with tapered rigid insulation, and will include a 30-year manufacturer warranty. The project is part of a Department of the Army Corps of Engineers solicitation (W912WJ25QA040) set aside for small businesses, with a construction value between $100,000 and $250,000, using NAICS code 238160 and a small business size standard of $19 million.
