• B. Owner select CxA; 3. Develop Cx Scope; 4. CxA review design intent document
• C. Cx is established as part of project; 2. Owner select CxA; 3. Develop Cx Scope
• D. Cx is established as part of project; 2. Owner select CxA; 3. CxA review design intent document; 4. Develop Cx Scope

Answer: (A)

The pre-design phase for comprehensive HVAC Cx aims to anchor commissioning in the project from the start. The best answer includes all four elements: establishing that Cx is part of the project, the owner selecting the CxA, developing the Cx scope, and the CxA reviewing the design intent document. Establishing Cx as part of the project ensures commissioning goals are integrated into budgets, schedules, and responsibilities early. Having the owner select the CxA ensures an independent, qualified party is chosen upfront. Developing the Cx scope sets clear objectives, deliverables, and responsibilities for the commissioning effort. The CxA reviewing the design intent document during this phase helps confirm that performance goals are understood and achievable before design decisions are finalized, enabling proper alignment and planning for the rest of the project. The other options omit one or more of these essential steps, making them incomplete for the pre-design stage.
