Facts are taken from the highest-ranked source (certificates and test reports, then install guides and datasheets, then warranties, then web pages); when sources disagree the specification says so, and safety facts take the conservative value. Every plan the designer draws from these figures is a concept plan, not for construction: the span tables behind its framing have been checked by a structural engineer, but a builder, building surveyor or certifier must check the plan before you build.
