Commissioning Issues Log Guide
How to structure and review a commissioning issues log for startup, testing, controls, TAB, owner training, closeout, and warranty follow-through.
A commissioning issues log tracks problems found during startup, testing, balancing, functional performance testing, controls verification, owner training, and closeout. It should be more than a punch list for systems.
The log is most useful when every item includes the affected system, location, responsible party, source requirement, current status, and verification method.
Recommended Fields
A clear log lets the commissioning agent, contractor, design team, owner, and controls vendor see the same issue without reconstructing context from emails.
- Issue number, date opened, system, equipment tag, and location.
- Observed condition, expected requirement, and source document.
- Responsible party, priority, due date, and current status.
- Related RFI, submittal, test report, photo, or drawing reference.
- Corrective action, retest result, close date, and owner acceptance.
Use the Log Earlier
The best commissioning logs begin before final testing. Startup issues, controls questions, access problems, and TAB constraints can be tracked as soon as they appear.
Helonic helps connect those issues to drawing conditions so the team can see whether a commissioning problem is isolated, repeated, or rooted in a coordination gap.
