Which role reviews design for adequate testing provisions, submits TAB data sheets for approval, coordinates work with master schedule, reviews site conditions prior to field work, submits complete and accurate TAB report, and participates in TAB verification?

• A. Architect
• B. Commissioning agent
• C. Test and balance contractor
• D. Design consultants

Answer: (C)

The role that handles the hands-on testing, data documentation, and final verification of HVAC balancing is the test and balance contractor. This person reviews the design to ensure there are clear testing provisions and points to measure, then prepares TAB data sheets and submits them for approval. They coordinate the TAB work with the overall master schedule so testing fits with other activities, and they review site conditions ahead of field work to ensure the test setup will be feasible and safe. They deliver a complete and accurate TAB report that records all measurements, adjustments, and balancing results, and they participate in TAB verification to confirm that systems perform as designed.

Architects and design consultants focus on creating the design itself and how the system should work, while a commissioning agent oversees the broader commissioning process and verifies TAB results, but does not typically perform the TAB data development or field testing tasks.
