Scheduling test and balance is the single most common pinch point on commercial closeouts. The work has to land after mechanical start-up and before final inspection, and the report has to be ready for the engineer’s review before the AHJ walk. Here is how to sequence it.
When scheduling test and balance belongs on the closeout plan
First, scheduling test and balance starts when the mechanical contractor confirms start-up readiness — typically 2-3 weeks before the engineer’s final walk. Specifically, the TAB agent needs every AHU fired, every pump primed, every VFD commissioned, and the BAS in auto. After that, our crew mobilizes the next business day.
How GCs handle scheduling test and balance with the mechanical trade
Furthermore, scheduling test and balance the right way prevents the punch-list cascade that turns closeout into a scramble. Therefore, the smart GC ties TAB mobilization to mechanical substantial-complete on the schedule, with float for re-test after deficiencies. Additionally, occupied-building work needs night-and-weekend coordination with operations.
