Tiers rather than a single permission
Administrative offices, meeting rooms and staff amenities generally sit in a general tier with ordinary commercial requirements. Clinical support areas such as waiting rooms, corridors serving clinical space and some storage may carry additional expectations about method, products and timing. Clinical areas themselves usually carry requirements about screening, health status, induction and sometimes escorting that go well beyond a commercial arrangement. Buildings shared between organisations complicate this further, since two occupiers on the same floor may apply different requirements to the same corridor.
Writing the scope against those tiers does two things. It gives the cleaner an unambiguous instruction about where they may go and what applies there, and it gives the organisation a document that maps onto its own access framework rather than cutting across it. Both are more useful than a scope describing the building as one environment with a general note about clinical areas.
