It is my understanding that structural metal framing belongs in Division 05, while non-structural metal framing belongs in Division 09.
My confusion comes from the answer to one of the case study questions on the PDD practice exams. The case study is about a 10,000 sf renovation in a manufacturing facility. The owner asks that the existing masonry walls be furred out to provide a newly finished drywall surface on metal studs. The question asks which Specification Divisions would be affected.
The answer key notes that 05 would need to be updated to include the studs. For this application, I thought that the metal studs would be considered non-structural metal framing, because all they are doing is holding up drywall.
Can anyone provide some clarification on the difference between structural metal framing from 05 and non-structural metal framing from 09?
