Building Automation Point-to-Point Verification

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 Procedure

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.

  1. Compare each sensor reading against a calibrated field instrument
  2. Command every actuator and valve through full travel; confirm feedback matches
  3. Verify schedules, setpoints and reset strategies against the sequence of operation
  4. Test overrides return to automatic after the timeout
  5. Document any point left in override, hand, or manual and why

Why This PM Exists

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.

What Skipping It Looks Like

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.

Setting the interval

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.

Common Questions

How often should this PM run?
Annual. 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.
How long does it take?
Budget about 4.0 hours for a technician working to the standard procedure. ChatterFix uses that estimate for capacity planning, then learns your plant's actual time from completed work orders.
What happens if we skip it?
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.
