About this file
This architectural plans document supports the City of Cheyenne's 2026 Various Roof Replacements project, which encompasses reroof work at six municipal facilities: George Cox Parking Garage, Ice and Event Center, City Records Building, Pioneer Park Center, Spiker Parking Garage, and the Street and Alley Building. The project involves removing existing roofing systems, insulation, coping, and downspouts, then replacing them with new EPDM roofing membranes, parapet coping, and associated flashing components. Specific work scopes vary by facility, ranging from 1,897 square feet at the Records Building to 186,000 square feet at the George Cox Parking Garage. All work must comply with 2024 International Building Code standards and achieve Class "A" roof assemblies with 90 mile-per-hour wind speed warranties. The project is designed by Plan One/Architects, with Steve Gaer as the City of Cheyenne's Facilities Manager contact and Britt Morgan, AIA, as the architect contact.
The design specifications establish minimum roof slopes of 1/4 inch per foot for adequate drainage and mandate that contractors verify all existing conditions in the field prior to work commencement. Contractors may substitute alternative EPDM roofing systems upon approval, provided the systems manufacturer and contractor assume responsibility for modifying details to accommodate their specific products, with no additional compensation available after bid opening. All existing mechanical, plumbing, and electrical equipment is designated to remain in place, with contractors responsible for replacing damaged boots, supports, and flashing around these installations. Demolition notes specify legal disposal of all removed materials and require notification to the Wyoming Department of Environmental Quality if asbestos-containing materials are encountered. The design basis references Carlisle and MBCI roofing products as primary standards, though equivalent systems may be substituted.
