Do building inspectors ever actually check to see - or care - that UL fire rated assemblies that are referenced on drawings are constructed with the proprietary products that the assembly was tested with? E.g., is that installed brand of gyp board or metal stud actually listed in the UL assembly? In over 25 years as an architect with a firm that does primarily commercial and public projects, I have never experienced this or heard of it happening. Just curious, and interested in the comments of building inspectors. Thanks.
