New construction commissioning costs as a percentage of total construction cost range from what?

• A. 0.5 to 1.5%
• B. 1.0 to 2.0%
• C. 0.1 to 0.5%
• D. 2.0 to 3.0%

Answer: (A)

Commissioning costs mirror the amount of planning, testing, and documentation needed to ensure all building systems perform as intended. For typical new construction projects, this work runs about half a percent to roughly one and a half percent of the total construction cost. That range covers creating the commissioning plan, coordinating with design and construction teams, conducting functional tests of HVAC, electrical, and plumbing systems, validating performance against design intent, training operators, and compiling turnover documentation. Lower ranges often don’t provide enough breadth for thorough verification, while higher ranges appear only on unusually large or complex projects.
