About this file
This is an Addendum clarifying the Scope of Work for West Texas A&M University (WTAMU) roofing projects across multiple campus buildings and facilities in Texas. The document outlines nine base proposals organized into three scope of work packages, encompassing roof replacement and repair work at WTAMU Classroom Center, Jack B. Kelly Student Center, Cornette Library, Connor Hall, Greenhouses, and Panhandle Plains Historical Museum. Proposals 1 through 5 involve removal of existing roof systems and installation of new two-ply modified bitumen roofing with polyisocyanurate insulation boards of varying thicknesses; Proposal 6 specifies removal and replacement of shingle roofing with architectural composition shingles at Connor Hall; Proposal 7 involves replacement of polycarbonate panels at the greenhouses; and Proposals 8 and 9 address roof coating and modified bitumen installation at the Panhandle Plains Historical Museum. All work includes HVAC and electrical disconnection and reconnection, removal and replacement of flashings and sheet metal, and requires compliance with NRCA, SMACNA, and ANSI/SPRI standards. Master plumber certification is required for all gas line testing and certification.
All proposals include manufacturer warranties ranging from two to twenty years for the new roof materials and systems, with two-year contractor warranties provided across all base proposals. New metal components, including coping caps, flashing, and accessories, shall be prefinished aluminum or as selected by the owner from available color ranges. Work specifications require compliance with ASCE 7 criteria for mechanically fastened base sheets and adherence to manufacturer guidelines for installation. The scope of work clarification addendum provides detailed specifications for deck preparation, insulation board installation methods, cricket installation, cover board application, and lap welding procedures, with cold-applied adhesive specified for most assemblies. The document does not specify pricing terms, bidding deadlines, site visit dates, or award timelines within the provided addendum text.
