Building Automation Point-to-Point Verification

Commissioning inspection template for verifying every BAS analog and digital input and output point against the controller readout and the physical device response.

Inspection Setup and Documentation

• Approved point list, sequence of operations, and control drawings available on site
  Verify the current approved BAS point list, sequence of operations, wiring diagrams, and control drawings are available for reference during testing.
• Test equipment calibrated and suitable for BAS verification
  Confirm meters, simulators, laptops, and calibration records are available and appropriate for the devices being tested.
• System in commissioning mode or approved test condition
  Verify the BAS is placed in the correct test state so point manipulation will not create unintended occupant impact or equipment damage.
• Inspector identified and work authorization confirmed
  Confirm the inspector, commissioning authority, or competent person is authorized to perform the test and that the work area is approved.

Point Identification and Mapping

• Point name matches controller database and field label
  Verify the BAS point name, controller address, and field label are consistent across the database, graphics, and physical device.
• Point type correctly identified as analog input, analog output, digital input, or digital output
  Confirm the configured point type matches the actual field device and intended control function.
• Point address and controller channel match approved submittal
  Verify the controller input/output channel, terminal number, and network address match the approved submittal and as-built documentation.
• Point description and units are correct in BAS graphics and database
  Confirm the displayed point description, engineering units, and scaling labels are correct and unambiguous.

Analog Input Verification

• Analog input value matches simulated or measured field condition
  Record the measured difference between the BAS readout and the applied field condition. Acceptance should be within the project tolerance for the specific point.
• Analog input scaling and engineering units are correct
  Verify the displayed value changes proportionally and the scaling matches the device range, such as 0-10 V, 4-20 mA, or temperature sensor range.
• Analog input responds smoothly without dropout, noise, or erratic fluctuation
  Confirm the signal is stable and does not show intermittent loss, spikes, or unrealistic oscillation during steady test conditions.
• Analog input alarm or fault status changes correctly on out-of-range condition
  Force an out-of-range or disconnected condition where safe and verify the BAS reports the expected alarm, fault, or bad status.

Analog Output Verification

• Analog output command matches BAS setpoint or override value
  Record the commanded output value and verify the controller output matches the intended setpoint or manual override.
• Field device responds correctly to analog output signal
  Verify the actuator, damper, valve, VFD, or other controlled device moves proportionally and in the correct direction.
• Output range, direction, and fail position are correct
  Confirm the output is configured for the proper signal range and that the device fails to the specified safe position on loss of signal or power.
• Manual override releases and returns control to automatic mode
  Verify any temporary override is removed and the point returns to normal automatic control without residual lockout.

Digital Input Verification

• Digital input changes state correctly when field contact is operated
  Verify the BAS status changes when the switch, relay contact, proof switch, or interlock is operated.
• Normal and abnormal states are correctly interpreted
  Confirm the BAS logic correctly identifies open/closed, on/off, proof/fail, or alarm/normal conditions.
• Input status is stable and free of chatter
  Verify the input does not chatter, bounce excessively, or intermittently drop out during steady operation.
• Associated alarm or interlock logic responds as designed
  Confirm the BAS alarm, shutdown, proof, or permissive logic reacts correctly to the digital input state.

Digital Output Verification

• Digital output energizes and de-energizes the field device correctly
  Verify the relay, contactor, starter, solenoid, or command output operates the intended field device.
• Output status feedback matches commanded state
  Confirm the BAS readout and any proof feedback indicate the correct state after the command is issued.
• Fail-safe behavior verified on loss of power, signal, or control
  Where safe and approved, verify the device transitions to the required safe state on loss of control power or command signal.

Final Review and Sign-Off

• All deficiencies and non-conformances documented with corrective actions
  Record each failed point, the observed deficiency, responsible party, and required corrective action.
• Inspection results reviewed with commissioning team and accepted
  Confirm the commissioning authority, controls contractor, and owner representative have reviewed the results and agreed on next steps.
• Inspector signature
  Signature of the inspector or commissioning authority completing the verification.
