Approximately what percentage of the total cost for construction HVAC commissioning does comprehensive commissioning represent?

• A. Approximately 80% of that for comprehensive commissioning
• B. Approximately 60%
• C. Approximately 40%
• D. Approximately 20%

Answer: (A)

The main idea is that most of the cost in construction HVAC commissioning goes to the comprehensive commissioning activities themselves. Comprehensive commissioning includes the thorough planning, documentation, system-wide integration, and extensive functional performance testing and tuning across all HVAC equipment and controls. Because these steps require coordinated effort across multiple trades, detailed checks, and verification of that the system meets the design intent and energy performance, they drive the largest share of the budget. For this reason, the cost is typically about four-fifths of the total construction HVAC commissioning expense. The remaining portion covers less intensive tasks like coordination, meetings, and any smaller, non-comprehensive activities. So, the best fit is that comprehensive commissioning represents roughly 80% of the total construction HVAC commissioning cost.
