DocuSign Envelope ID: E9612703-F25B-492D-9C8C-EC3F9728ECE6 <br /> by the balancing agency's certified test-and-balance engineer. Submit three copies of the certified <br /> test-and-balance report to the Engineer. The report shall be evidence that the system has been tested, <br /> adjusted, and balanced in accordance with AABC,NEBB, or ASHRAE standards; are an accurate <br /> representation of system performance at the completion of testing and balancing;and are an accurate <br /> record of all final quantities measured,to establish normal operating values of the systems. <br /> As part of the report, submit one copy of the contract drawings marked "as-built" to the Engineer. <br /> Indicate actual CFM at each grill, static pressures, inlet and outlet water and air temperatures, <br /> pressures, GPM at each, and test point codes. Record the following items at each cooling and <br /> heating element: inlet and leaving water and air temperatures,pressure drop of each coil or bypass <br /> valve, water and air metering device readings. For each pump record operating and discharge air <br /> pressures and final 'I'MH. Record identification of all measured points to cross-reference with <br /> tabulated data. Verify as-installed locations of all dampers, balancing valves, and other control <br /> devices are accurately shown. <br /> The test-and-balance report shall be recorded on report forms conforming to recommended forms in <br /> AABC or NEBB standards and as approved by the Engineer in the test plan. As a minimum the <br /> report shall include: <br /> Preface - a general description of the system, equipment, and controls, and discussion of any <br /> abnormalities and problems encountered. <br /> Instrumentation list-The list of instruments including type,model, manufacturer, serial number, <br /> and calibration dates. <br /> System identification - Supply, return, and exhaust openings, zones, traverse points, terminal <br /> equipment such as VAV boxes,fans, air handling units,heating/cooling coils,and other equipment <br /> shall be identified to correspond to the identification used on the report data sheets. Such <br /> identification shall also correspond to the identification on the project drawings, field labels, and <br /> owner designations. <br /> Air handling equipment test report forms -Record the following for all air handling equipment in <br /> each mode of operation:manufacturer,model number,serial number; all design and manufacturer- <br /> rated data; total actual CFM by traverse or other approved method, CFM grill totals; suction and <br /> discharge static pressure of each fan; outside air and return air total CFM; actual operating current, <br /> voltage, and brake horsepower; motor and fan final RPM; fan and motor sheave manufacturer, <br /> model, size,number of grooves,and center distance;belt size and quantity;static-pressure controls <br /> final operating set points. <br /> Heating and cooling coil test forms-Record the following items for each heating or cooling coil: <br /> manufacturer;all design and manufacturer's rated data;rated and actual water pressure drop through <br /> each coil and related GPM; rated and actual static pressure drop across each coil; entering and <br /> leaving water temperatures; wet-bulb and dry-bulb temperatures of air entering and leaving each <br /> 15H-3 5 <br />
