This is a bid drawing attachment for a roof replacement project at Southern Oregon University's Computing Services Center West Wing, located at 480 University Way in Ashland, Oregon. The project scope encompasses the complete replacement of existing single-ply EPDM membrane roofing and clay tile roofing with new 60-mil PVC membrane and 22-gauge standing seam metal roofing. The membrane replacement work covers approximately 9,000 square feet, while the metal roof area encompasses approximately 3,400 square feet. Key work items include demolition and disposal of all existing ballast, EPDM membrane, clay tile, wood cleats, blocking, and underlayment; installation of new mechanically-fastened 60-mil PVC membrane with a 20-year NDL warranty over 1.5-inch DensDeck on low-slope roofs; installation of new 22-gauge pre-finished standing seam metal roofing at pitched roof sections; replacement of nine roof drains and drain guards; removal of two CATV antennas and associated equipment; installation of new walk pads and a Guardian CB-12 fall protection anchor; and removal and replacement of metal parapet copings. Bidders are required to field verify all dimensions and quantities prior to submitting bids, with the drawing dated April 24, 2026, and designated as Bid #ITB2026-08.

The drawing specifies detailed construction requirements including membrane installation methods, material specifications, and coordination requirements referenced in Attachment A Project Manual. The existing tapered insulation system is to remain in place on low-slope roof areas. All work must protect the JPR antenna during demolition and construction activities, with a 20-foot by 20-foot "No Access" zone established using delineators and caution tape, as the antenna will be permanently relocated by Southern Oregon University following roof completion. Interior parapet walls require either full adhesion or mechanical fastening to prevent billowing, and roof warranties extend to the outside face-of-wall.
