Glazed atrium rooflight and its steelwork cleaned over night shifts, using a mobile tower on the lobby floor and rope access from the roof structure above it.
Project context
Building described without naming the client. Two access methods on one job, worked outside business hours.
A large glazed atrium rooflight carried on black steel and white beams sits directly above a marble lobby that stays in use. The glazing and the beam structure needed cleaning at height without taking the floor out of service during the day.
We worked night shifts, with a mobile aluminium tower set on the lobby floor for the reachable beam runs and rope access technicians suspended from the roof structure for the glass and steelwork the tower could not reach. Vacuums were slung from the steelwork, technicians wore respiratory protection and head torches, and the glass was cleaned pane by pane.
Dust removed from the beams and gusset plates and the rooflight glazing wet-cleaned, with the tower struck and the lobby reinstated before opening each morning.
