Everyone who walks through your building is an owner of it
A public facility does not get graded by a customer. It gets graded by residents, and every one of them helps pay for it. A slush covered arena lobby on a Saturday morning is seen by a few hundred people before ten o'clock, and one of them will bring it up at the next council or committee meeting.
Public buildings also run on schedules nobody fully controls. Ice rentals, program bookings, council nights, polling days, transit shifts, hall rentals. The cleaning has to happen around all of it, in the hours the building is not in use, without a manager standing there to watch the work get done.
Most facility managers we speak with are not looking for a different scope of work. They are looking for a contractor who delivers the same scope the same way every week, and can show it in writing when someone asks.
