Who is responsible for Post-Acceptance Phase Monitor Warranty Issues Work?

• A. CxT
• B. CxA
• C. Shared
• D. Internal Team

Answer: (A)

The ongoing monitoring and handling of warranty issues after acceptance are best handled by the on-site Commissioning Technician. The CxT is the person who works directly with the installed equipment, understands the control sequences, and can observe real performance to identify whether a problem is covered by warranty. They log issues, coordinate with contractors and manufacturers, and drive the necessary warranty fixes, keeping documentation and follow-up actions current. The CxA provides overall commissioning oversight and verification, but the day-to-day warranty follow-up is the CxT’s responsibility because it requires hands-on familiarity with the equipment and systems. The other roles aren’t as directly situated to manage this ongoing, on-site warranty monitoring and action.
