For TAB projects, which contracting arrangement is recommended?

• A. A third party directly contracted with the owner
• B. The contractor performing TAB contracts with owner
• C. The equipment manufacturer contracts with owner
• D. The general contractor handles TAB with no owner involvement

Answer: (A)

Independence and direct owner control of the TAB work is the strongest approach. When a separate TAB contractor is contracted directly by the owner, the testing, adjusting, and balancing are performed by an impartial party whose sole focus is verifying that HVAC systems meet the design intent and performance criteria. This independence reduces the risk of biased results or pressure to under- or over-state performance, and it ensures clear accountability, proper documentation, and easier acceptance and commissioning. If the TAB work is contracted through the general contractor or by the equipment manufacturer, conflicts of interest or perceived bias can arise, making it harder to trust the results. Direct owner engagement with an independent TAB firm also keeps the owner in control of scope, schedules, and acceptance criteria, and supports transparent communication and handover. So, the recommended arrangement is a third-party TAB contractor contracted directly by the owner.
