Which item is a main design-phase activity?

• A. Write Cx plan
• B. Review submittals
• C. Coordination meetings
• D. TAB HVAC systems

Answer: (A)

In the design phase, the key activity is establishing how commissioning will be executed. Writing the Cx plan sets the commissioning approach for the entire project by outlining objectives, scope, responsibilities, deliverables, and the schedule. This plan provides the foundation for all later Cx activities and ensures everyone knows what will be tested, when, and by whom. Submittal reviews, coordination meetings, and TAB of HVAC systems are more aligned with later stages. Submittal reviews happen as design is translated into construction details and products are proposed and approved. Coordination meetings occur throughout design and construction to resolve conflicts and align systems. TAB (testing, adjusting, and balancing) of HVAC systems is a construction-startup activity focused on verifying installed equipment meets performance criteria, typically after installation. Therefore, the design-phase activity that best fits the question is writing the Cx plan.
