1.4 DETAILED REQUIREMENTS

A. Adjusting and Balancing:

1. Prior to beginning the balancing work, obtain from the general contractor the latest version of the mechanical drawings including addenda, revisions, change orders, etc.

2. Adjust and balance all portions of the mechanical systems to produce indicated results within limits of minus 5 or plus 10 percent or as subsequently directed by the Owner’s authorized representative. Any deviation outside these tolerances must be documented and submitted through the SGC‑3 RFI process prior to acceptance.

3. Balancing data may be spot checked with instruments similar to that used by the balancing firm.

4. If, in the judgment of the Owner’s authorized representative, the discrepancies warrant additional adjustment, readjust and rebalance the systems at no additional project cost. Corrective TAB work required due to Contractor‑caused deviations remains at no additional cost; corrective work due solely to Owner‑directed changes or security‑related access restrictions shall follow GC D (Changes in the Work).

5. Where power exhaust fans are specified, set power exhaust fans to operate as shown on drawings and set power exhaust fan cfm percentage as shown on drawing.
