Building automation is the one system where the maintenance record and reality drift apart without anything breaking. A sensor reads three degrees high, an actuator loses its linkage and stops at seventy percent travel, a point gets put in hand during a troubleshooting call and never gets released. The graphics still look correct. The sequence of operation is still what the drawings say. But the building is being controlled from numbers that are wrong.
The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

You get a building that runs on overrides. Comfort complaints get answered by widening setpoints rather than fixing the sensor, simultaneous heating and cooling goes unnoticed because both valves report closed, and energy consumption climbs for reasons nobody can trace. The overrides accumulate over years and eventually no one on site knows which points are trustworthy — at which point the only honest answer is a full re-commissioning.
Annual for the full point-to-point pass. Any point touched during a service call should be verified and released before the technician leaves, which is what keeps the annual from turning into a re-commissioning project. Buildings with heavy tenant churn or frequent fit-outs justify twice a year.
This procedure — and every other PM for your industry — is already built into ChatterFix. Pick your industry and it lands on the right equipment, on the right interval, in about three minutes.
