Confirm what a 'fire-taped' (Level 1) finish legally covers versus a full Level 4/5 finish before scoping a contract for concealed assemblies like above-ceiling plenum walls.

Steps
Pull GA-214's Level 1 definition: tape embedded in joint compound with no additional coats, used in plenum areas, attic stock, or areas not normally viewed
Distinguish this from Level 4 (used under most flat paints) and Level 5 (skim coat, critical lighting) to avoid scope disputes
Check whether the local fire marshal or UL assembly listing requires taped joints specifically (not just fire-taping colloquially) for the rated assembly to perform as tested
Verify the GA-600 assembly design being used doesn't have additional finish requirements baked into its listing (some rated shaftwall/corridor assemblies specify joint treatment)
Document 'fire-tape' terminology in the contract using the GA-214 Level 1 language, since 'fire-tape' is jobsite jargon, not a defined term in GA-214 itself
Known gotchas
'Fire-tape' is a trade term, not an official GA-214 level name -- GA-214 calls it 'Level 1'; contracts using informal terms invite disputes over scope
Level 1 finish does not by itself confer the fire rating -- the fire rating comes from the tested assembly (board type/layers/framing) per GA-600 or the UL listing, not the joint finish level
