Issues Management, Deficiency Resolution, and Acceptance
Issues management is the disciplined tracking of problems from identification through resolution and verification. Each issue should record a unique ID, date, location, system, description, responsible party, priority, required corrective action, and closure evidence. The issues log is a living document reviewed at progress meetings.
Deficiencies fall into categories: design deficiencies, installation/construction deficiencies, and operational/performance deficiencies. Resolution requires the responsible party to correct the work, the CxA to verify the correction, and retesting where performance was affected. The candidate must understand that the CxA does not direct the contractor - issues flow through the owner and design professional per contract.
Acceptance is tied to successful completion of functional testing and closure of critical issues. Traps: (1) closing issues on a promise rather than verified evidence; (2) treating all issues as equal priority - use severity ranking so critical safety/operational issues block acceptance; (3) allowing the contractor to self-certify closure without CxA verification; (4) confusing substantial completion with final Cx acceptance.
Rule of thumb: an issue is closed only when the CxA has verified the correction and, if performance was affected, retested successfully. Worked example: a VAV box fails to maintain minimum airflow. The contractor recalibrates the damper actuator and provides trend data; the CxA reviews the data and witnesses a retest before closing the item.
