What lives only in a cleaner's head
The rear door that sticks and needs lifting. The alarm zone that trips if the storeroom is opened before the panel is set. The tenant who works late on Wednesdays. The room that is always locked and is not in the scope. The bin that must go out before six because the collection is early. None of these are in any document, and all of them cause a problem the first time someone new attends.
Individually they are trivial. Collectively they are the difference between a smooth shift and a night that generates three phone calls and a complaint. Capturing them takes ten minutes with the regular cleaner and a notebook, and the resulting list is worth more to a replacement than the formal scope, because the scope describes the work and the list describes the building.
