A booked dock is a precondition, not a courtesy
Docks under commercial towers are managed because they have to be. Vehicle heights, turning space and lift capacity all constrain what can happen at once, and an unbooked contractor standing in a bay with equipment is an obstruction rather than a service. Treating the cleaning attendance as something that fits around everything else is how the dock floor ends up permanently half done. It also puts the crew in the same queue as everyone else, which is exactly where a contractor should be.
The scope should therefore record the booking process itself: who holds the dock diary, how far ahead a slot must be requested, and what the standing arrangement is for recurring attendances. Where the building will only release the dock at a particular hour, that hour becomes the schedule. It is far better to write that than to price a service against a window that does not exist.
