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. A minimum of two inspections <br /> are required as follows: (1)when 60 percent of the ductwork is installed;(2)when 90 percent of the <br /> equipment is installed. The balancing agency shall submit a brief written report of each inspection to <br /> the Engineer via the Mechanical Contractor. <br /> The balancing agency shall witness start-up and tests for all major HVAC equipment. Copies of test <br /> reports, including manufacturer's start-up check lists included in manufacturer's installation <br /> instructions, shall be included in the Test-and-Balance report. <br /> System balancing and testing shall not begin until system has been completed and is in full working <br /> order. This contractor shall put all HVAC systems and equipment into full automatic operation and <br /> shall continue such operation throughout the testing and balancing period. Adequate time shall be <br /> allowed in the construction schedule for completion of all specified testing and balancing within the <br /> contract completion date, and prior to requesting final inspection. <br /> During system balancing and testing, field data in rough form shall be forwarded daily to the <br /> Engineer. The balancing agency shall coordinate and review worksheets and findings daily with the <br /> Engineer as testing and balancing progresses to obtain direction for adjustments. The balancing <br /> agency shall notify the Engineer daily of any controls found inoperative, out of calibration, or <br /> otherwise needing adjustment. Any critical deviation of equipment capabilities or performance from <br /> design and specification requirements shall be immediately reported to the Engineer for his action, <br /> and noted in the Test-and-Balance report, together with recommendations for efficient and <br /> economical correction of the deficiency. <br /> Once system balancing and testing is completed,provide a minimum of one day's training program <br /> for the Owner's designated personnel which shall stress operation of the complete control system. <br /> During this period, log all temperatures, and temperature drops/rises across equipment hourly. <br /> Allow system to stabilize; set down 5 degrees, stabilize; set up 10 degrees, stabilize; return to <br /> original setpoint,stabilize;and log at each setting. Transmit rough logs to Engineer within 24 hours <br /> of completion of this test, including names of Owner's personnel present. <br /> 15H-32 <br />
