Everything travels by hand
In a building without a lift, machines, product, water and waste all move on the stair. That rules out floor machines above ground level in most cases, limits the water available for any wet task, and adds substantial time to every attendance. It also introduces a manual handling consideration that a ground-floor scope never has to address.
Recording the constraint properly means measuring the stair width, the turn at each landing and the narrowest doorway. Those measurements determine what is possible. A quote built from floor area alone will assume equipment that cannot reach the floors it is meant to clean, and the resulting scope is unworkable from the first night. Recording the measurements in the proposal explains the pricing, which is otherwise difficult for an occupier to reconcile with the floor area.
