<br />RFP 24-057 <br /> <br />I <br /> <br />, 3.02 <br /> <br />I <br /> <br />587-0702 <br /> <br />and become thoroughly acquainted with the design intent. <br />2. Obtain copies of approved shop drawings of all new and existing air <br />handling equipment that is part of the complete Foul Air Collection System. <br />3. Compare design to installed equipment and field installations. <br />4. Walk the system from the system air handling equipment to terminal units to <br />determine variations of installation from design. <br />5. Check filters for cleanliness. <br />6. Check dampers for correct and locked position for completeness of <br />installation before starting fans. <br />7. Prepare report test sheets for both fans and affected treatment units. <br />Prepare a summation of required treatment unit ventilation volumes to <br />permit a crosscheck with required fan volumes. <br />8. Determine best locations in main and branch ductwork for most accurate <br />duct traverses. <br />9. Place balance dampers in the full open position. <br />10. Prepare schematic diagrams of system "as-built" ductwork and piping <br />layouts to facilitate reporting. <br />11. Lubricate all motors and bearings <br />12. Check fan belt tension <br />13. Check fan rotation <br /> <br />MEASUREMENTS <br /> <br />A. Provide all required instrumentation to obtain proper measurements, calibrated to <br />the tolerances specified in the referenced standards. Instruments will be properly <br />maintained and protected against damage. <br /> <br />B. Provide instruments meeting the specifications of the referenced standards. <br /> <br />C. Use only those instruments which have the maximum field measuring accuracy <br />and are best suited to the function being measured. <br /> <br />D. Apply instrument as recommended by the manufacturer. <br /> <br />E. Use instruments with minimum scale and maximum subdivisions and with scale <br />ranges proper for the value being measured. <br /> <br />F. When averaging values, take a sufficient quantity of readings which will result in a <br />repeatability error of less than 5 percent. When measuring a single point. repeat <br />readings until 2 consecutive values are obtained (+/- 2%). <br /> <br />G. Take all reading with the eye at the level of the indicated value to prevent parallax. <br /> <br />H. Use pulsation dampeners where necessary to eliminate error involved in <br />estimating average of rapidly fluctuation readings. <br /> <br />I. Take measurements in the system where best suited to the task. <br /> <br />15950-5 <br />
