Melbourne's commercial sites range from CBD towers and Southbank offices to converted warehouses in Richmond, Cremorne and Collingwood, and large industrial sites in the west and around Dandenong. CBD buildings usually mean after-hours access, security inductions and set loading-dock times, so we plan rosters around building management rules. Melbourne's changeable weather also means wet entries and carpets through winter, so entry matting, hard-floor care and spill response get extra attention from May to September. Hospitality sites in the CBD and inner suburbs are cleaned around late trading, with early-morning resets before the doors open again.
