TAB work is completed and documented in which phase?

TAB work is completed and documented in which phase?

• A. Pre-design phase
• B. Design phase
• C. Construction phase
• D. Acceptance phase

Answer: (B)

TAB work establishes the tests, targets, and reporting format that will verify the system meets the design intent. That planning and documentation are laid out in the design phase, so the TAB plan and its criteria are defined upfront and linked to the design documents. The actual field testing and balancing occur during construction, but the documentation of those results is anchored to the design criteria established earlier, making the design phase the phase where TAB work is completed and documented. Pre-design is too early to set the test criteria, construction is where the testing happens, and acceptance follows after performance is demonstrated, not where the TAB plan is finalized.
