The lift car and its thresholds carry everything
A goods lift car is a small floor that receives every wheel and every boot on the route. Its floor, its thresholds and the strip of landing either side take a concentration of traffic out of all proportion to their area, and they are also what anyone waiting for the lift looks at. Those few square metres repay attention more than almost any other surface in the building.
Scoping them explicitly, rather than leaving them inside a general reference to lift lobbies, is what gets them done. The car floor, the door tracks at the car and at each landing, and the threshold plates all need naming. Door tracks in particular collect grit that affects how the doors run, and cleaning them is straightforward provided nothing is adjusted or lubricated. Threshold plates in particular collect grit in the joint where the car meets the landing.
