P.E. Y Cartier,Y ST. Lucie County, Permitting Engineer's review is for general conformance with the design concept and contract documents.Markings or comments shall not be construed as relieving the Contractor from compliance with the project plans and specifications, nor departures therefrom. The Contractor remains responsible for details and accuracy, compliance with the Contract Documents and intent,for confirming and correcting all quantities and dimensions,for selecting appropriate fabrication processes,for techniques of assembly,and for performance of work in a safe manner. OVERALL DISPOSITION: Revise and Resubmit 1. Verify the recorded values for AHU-1. The summation of the outside air (1,852 CFM) and return air (4,665 CFM) exceed the supply air from the unit (total of outside and return is 6,517 CFM, recorded supply is S,341 CFM). The summation of the return air from the AHU- 1 table is 2,808 CFM, which is not consistent with the value recorded in the AHU-1 data sheet (4,665 CFM). 2. It is noted that the final total supply air for RTU-1 is considerably lower than design (73%). 3. There is a difference of 356 CFM between the recorded RTU-2 supply air (1,986 CFM) and return air(1,630 CFM). This implies that the outside air damper on RTU-2 is not completely closed. Ensure the outside air damper on RTU-2 is completely closed and sealed and re- measure to ensure the supply and return airflow values are the essentially the same. 4. It appears exhaust fans EF-1, EF-2 and EF-3 have not been rebalanced to their respective new airflows as required by sheet M1.1, Plan Reference Notes 14, 13 and 15 respectively. Rebalance exhaust fans to values indicated, record and re-submit for review. S. The Outside Air Unit test data is missing the entering and leaving dry bulb and wet bulb air temperatures across the unit heat pipe coils. Measure and record these values and include in the test report for evaluation. Refer to sheet M4.1, Grade Mounted Package 100% Outside Air Unit Schedule for indicated values across the pre-cooling and reheat coils. 6. Confirm the 52 degree off-coil temperature indicated in the Outside Air Unit report form is the temperature leaving the DX cooling coil prior to entering the heat pipe reheat coil. 7. Measure and record the total unit amp draw and voltage at design conditions. It appears the recorded values for amps and voltage are for the evaporator fan only. Refer to sheet M4.1,Grade Mounted Package 100%Outside Air Unit Schedule for unit design MCA value. Shop Drawing Review Comments Page 2 of 2 8. Rebalance total airflow from the Outside Air Unit to within 10% of the total design (1,540 CFM maximum) as opposed to the 1,852 CFM recorded.
