About this file
This is an Attachment B Drawings document for Invitation to Bid (ITB) 2026-05 issued by Southern Oregon University (SOU) for membrane roof replacement work at two campus buildings located in Ashland, Oregon. The project involves replacing existing single-ply membrane roofing with new 60-mil, mechanically fastened PVC membrane at the Art Building (545 Indiana Street) and the Marion Ady Building (1290 Siskiyou Boulevard). The total area of work spans approximately 15,000 square feet across both buildings. The drawings provide detailed roof plans at a scale of 1/16" = 1'-0" and include a vicinity map showing the locations of both buildings. Bidders are required to field verify all dimensions and quantities prior to submitting a bid.
The scope of work includes removal and disposal of existing PVC membrane and cover board, installation of new Densdeck cover board mechanically fastened, installation of new 60-mil PVC membrane mechanically fastened, and removal and reinstallation of existing flashings and copings or installation of new pre-finished flashings and parapet caps at the contractor's option. Additional work includes installation of five Guardian CB-12 fall protection anchors at specified locations, installation of recycled rubber splash blocks, walkpads measuring 2.5 feet by 4 feet, and reuse of existing roof drains with new clamp rings as required by the membrane manufacturer. The contractor must provide a 20-year non-delegable (NDL) manufacturer's warranty with coverage extending to the outside face-of-wall, and all detailed requirements are specified in the project manual.
