| | |
| | 1) SHEET M-1: THE CHILLER ROOM VENTILATION CALCULATIONS |
| | SHALL BE BASED ON THE AMOUNT OF REFRIGERANT (1600 LBS.) |
| | IN CHILLERS 1 & 2 BECAUSE THEY OPERATE TOGETHER AS A |
| | SINGLE SYSTEM. PLEASE REVISE THE CALCULATIONS, AND |
| | SELECT AN EMERGENCY EXHAUST FAN SIZED CONSISTENTLY WITH |
| | THE CALCULATION- SECTION 1105.6.4 FMC-10. |
| | 2) M-2: CLARIFY ON THE PLANS HOW THE NORMAL VENTILATION |
| | SYSTEM IS BEING CONTROLLED. DOES THE EF-7 ROOF FAN RUN |
| | CONTINUOUSLY, BY AN INDIVIDUAL SWITCH, VIA CONNECTION |
| | TO A LIGHT SWITCH? PLEASE NOTE THAT PER SECTION 1105.6, |
| | VENTILATION SYSTEMS FOR MACHINERY ROOMS SHALL BE |
| | CAPABLE OF EXHAUSTING THE MINIMUM QUANTITY OF AIR AT |
| | NORMAL OPERATING AND EMERGENCY CONDITIONS, MEANING THAT |
| | THE REQUIRED NORMAL EXHAUST RATE SHALL BE MAINTAINED |
| | OVER AND ABOVE THE REQUIRED EMERGENCY EXHAUST RATE. |
| | PLEASE CORRECT THE NOTE SPECIFYING EF-7 TO SHUT DOWN |
| | WHEN EF-CH-1 ACTIVATES. |
| | 3) REFRIGERANT LEAK DETECTION AND ALARM: A) THE |
| | ENGINEER OF RECORD SHALL PROVIDE REVIEWED AND APPROVED |
| | TESTING DATA, OR REPORTS FROM QUALIFIED SOURCES |
| | INDICATING THE TLV-TWA (OR TOXICITY MEASURE CONSISTENT |
| | THEREWITH) FOR THE R-123 REFRIGERANT. IN CONJUNCTION |
| | WITH THOSE REPORTS THE ENGINEER SHALL ALSO SUBMIT |
| | REVIEWED AND APPROVED MANUFACTURER?S SPECIFICATIONS FOR |
| | THE REFRIGERANT LEAK DETECTORS. BASED ON THE REPORTS |
| | AND SPECIFICATIONS , THE REVISED PLANS SHALL INDICATE |
| | THE SPACING OF THE DETECTORS, THEIR EXACT MOUNTING |
| | LOCATIONS, AND AT WHICH VALUE OR LEVEL OF REFRIGERANT |
| | DETECTION THEY WILL ACTUATE THE ALARM SYSTEM - SEE |
| | SECTION 8.11.2.1 ASHRAE 15, AND SECTION 8.6 ASHRAE 34, |
| | AND SECTION 53.11.2.1 FLORIDA FIRE PREVENTION CODE. B) |
| | SHOW ON THE PLAN THE LOCATION OF THE REQUIRED ALARM |
| | NOTIFICATION DEVICE AT THE STAIRWELL ENTRANCE PER |
| | ASHRAE 15 AND FFP. C) PROVIDE A SEQUENCE OF OPERATION |
| | DIAGRAM ON THE PLAN FOR THE ALARM SYSTEM. |
| | 4) PROVIDE DETAILS FOR, AND THE TERMINATION LOCATIONS |
| | OF PRESSURE RELIEF DEVICES, FUSIBLE PLUG AND PURGE |
| | SYSTEMS PER SECTION 1105.7 FMC-10. PLEASE NOTE ALL |
| | SYSTEMS SHALL TERMINATE 15 FT. ABOVE THE ADJOINING |
| | GRADE (MAIN ROOF LEVEL) AND 20 FT. FROM ANY VENTILATION |
| | OPENING. |
| | 5) THE TERMINATION OR DISCHARGE LOCATION FOR THE NEW |
| | EF-CH-1 SHALL BE LOCATED A MINIMUM OF 10 FT. ABOVE THE |
| | ROOF LEVEL PER SECTION 501.2(2) FMC-10. PLEASE REVISE |
| | THE PLAN ACCORDINGLY. |
| | 6) SUBMIT MANUFACTURER'S SPECIFICATIONS AND A MIAMI |
| | DADE NOA OR FL. PRODUCT APPROVAL FOR THE NEW EXHAUST |
| | FAN. ALL SUBMITTALS SHALL BE REVIEWED AND APPROVED BY |
| | THE ENGINEER OF RECORD. |
| | 7) PROVIDE DETAILS FOR ANCHORING THE CONDENSER AND |
| | CHILLED WATER PUMPS, AND ANY REQUIRED PIPING SUPPORT |
| | STANDS TO THE EXISTING SLAB. |
| | 8) INDICATE ON THE PLAN WHAT NECESSARY ALTERATIONS WILL |
| | BE MADE TO THE EXISTING STRUCTURE TO FACILITATE REMOVAL |
| | AND REPLACEMENT OF THE CHILLERS AND PUMPS, AND PROVIDE |
| | A DETAILED WORK SCHEDULE REPORT FROM BEGINNING TO TOTAL |
| | COMPLETION OF THE PROJECT. |
| | 9) PLEASE NOTE THAT COMMISIONING OF THE SYSTEM IS |
| | REQUIRED FOR FINAL APPROVAL OF THE PROJECT PER SECTION |
| | 503.2.9 FBC-10 ENERGY CONSERVATION. THE ENGINEER OF |
| | RECORD SHALL PROVIDE EVIDENCE OF SYSTEM COMPLETION |
| | INCLUDING A WRITTEN BALANCE REPORT TO BE PROVIDED TO |
| | THE OWNER OF THE BUILDING OR DESIGNATED REPRESENTATIVE. |
| | PLEASE PROVIDE NOTES ON THE PLAN DETAILING THE TESTING |
| | AND BALANCING PROCEDURE. |
