This submittal shall also indicate that the <br /> balancing agency has reviewed the Contract Documents to ensure that all necessary dampers, <br /> balancing valves, and other devices required for correct balance and adjustment of the system are <br /> provided for, and note any potential problem areas. <br /> During construction,the balancing agency shall inspect the installation of pipe systems,sheet metal <br /> work, temperature controls, HVAC equipment, and other component parts of the system. The <br /> inspection shall be performed periodically as the work progresses.
