Preventive work
AC servicing, filter cleaning, drain cleaning, mattress rotation, pest control — on a schedule the night audit runs, over rooms or machines.
Under *Housekeeping desk → Preventive*, the hotel writes what is done before it breaks: AC servicing, AC filter cleaning, drain cleaning, descaling, mattress rotation, curtain washing, carpet and sofa shampoo, pest control, grout cleaning, deep cleaning, window cleaning, water-tank cleaning, fire-safety checks, generator service — or your own. Each has a cadence (daily, weekly, monthly, quarterly, seasonal, every N days) and a scope:
- every room, one room type, or one room — makes a visit for housekeeping or a ticket for engineering;
- one area — makes a round on that area;
- one machine, or every machine of a kind (every AC, every geyser) — makes a ticket per machine that names the machine and its room. When the ticket is fixed, the machine's service history says so by itself (see *Equipment*);
- the whole property — one ticket (pest control of the building).
A round is spread: quarterly mattress rotation over 10 days takes a tenth of the rooms each day, in room order; "every AC, monthly, over 10 days" takes a tenth of the ACs. The night audit generates the day's work; it appears on the board and the engineering queue like anything else.
Nothing scheduled vanishes. A scheduled visit not done by the end of its day is written on the *Not done* register and carried to the next day. A scheduled ticket past its deadline goes on the register too, and the engineer and supervisor are told.
