Facility preventive maintenance has a rhythm that plant and fleet programmes do not: most of it is seasonal, and most of it is constrained by people being in the building. Heating serviced before the cold, cooling before the heat, roofs and drainage before the wet, and almost everything noisy done when the building is empty. That makes the year the natural planning unit rather than the week, and it changes what a good schedule looks like for a facilities manager.
Plan the year backwards from the seasons
Work out which systems must be ready by which month, then place their services far enough ahead that a failure found during the service can still be fixed before the season. Servicing heating in October is not preventive maintenance, it is a discovery exercise with no time to act on what it finds. The lead time is the part sites forget to build in.
Occupancy is the constraint, so book the windows early
Quiet periods in a building are known a year ahead: holidays, closures, term breaks, shutdowns. Those windows are where the disruptive work goes, and they fill up. A facilities programme that identifies its noisy or intrusive jobs and claims the windows early gets them done; one that schedules by due date alone finds every window already taken by somebody else.
Statutory and insurer-driven work sits on its own clock
Buildings carry inspections and examinations driven by regulation or by an insurer rather than by wear, and those dates are not yours to move. Keep them on the same schedule so nothing is invisible, and mark them as fixed rather than flexible. What those requirements are, and which apply to your building, is a matter for your regulator, your insurer and your own competent person, not for a maintenance product.
Questions people ask about facility preventive maintenance
Should facility maintenance be in-house or contracted?
Most buildings are a mixture, and the programme should cover both identically. The interval is a contractor visit rather than your own labour; the questions of when it is due, whether it happened and what was found do not change.
How far ahead should a facilities plan run?
A rolling year, reviewed quarterly. Shorter than that and the seasonal lead times are missed; longer and the detail is guesswork.
What is usually missing from a facilities programme?
The record of what contractors found. Sites frequently know a visit happened because the invoice arrived, and cannot say what the report said, which makes the next visit start from nothing.
