About this file
The document is a comprehensive set of construction documents for the roof replacement project at Suffolk County Community College's Smithtown Science Building, located at 533 College Rd, Selden, NY 11784. The project involves a complete roof replacement for the Science Building, including removing existing roof coverings, repairing substrate damage, and installing a new SBS modified roofing assembly. The construction documents are dated March 31, 2025, with the project number SCCC Project No. 2149 and WFC Project No. 24-15885. The documents include detailed technical specifications, code compliance tabulations, roof construction plans for multiple building levels, and specific roofing installation details.
The project requires compliance with the Existing Building Code of New York State (2020) and the Energy Conservation Construction Code of New York State (2020). Key technical requirements include installing roof coverings that meet Class "B" roof assembly standards, using polyisocyanurate board insulation complying with ASTM C 1289, and ensuring wind resistance and impact resistance testing for the new roofing system. The project is classified as a Risk Category III building, with wind speeds estimated between 130-140 MPH. The roofing system must also meet specific energy efficiency requirements, including a minimum R-30 continuous insulation for Climate Zone 4. The documents provide extensive technical guidance for contractors, including detailed installation methods, flashing techniques, and specific requirements for penetrations, drains, and roof edges.
