What should an Issues Log track in Cx?

• A. Equipment warranties, budget, milestones, and weather impacts.
• B. Nonconformances, actions, responsibilities, status, and closure dates.
• C. Design intent and regulatory approvals only.
• D. Contractor invoicing and payment status.

Answer: (B)

An Issues Log in commissioning is a living record of problems found during the process and how they are addressed. The best answer captures nonconformances, the actions required to fix them, who is responsible, the current status, and the closure dates once the item is resolved. This structure keeps accountability clear, shows progress, and ensures nothing is forgotten before occupancy. It also provides an auditable trail that demonstrates issues were identified, assigned, resolved, and formally closed.

Warranties, budget, milestones, and weather impacts belong to broader project management or risk planning rather than the specific function of tracking issue resolution. Design intent and regulatory approvals relate to planning and compliance, not the ongoing process of managing items that need correction. In short, the log is about what must be corrected, who will fix it, how it will be verified, and when it will be closed.
