| | |
| | FBC 2004 CODE FAMILY W/ 2005 AND 2006 REVISIONS FBC |
| | CH.1 AS AMMENDED BY THE CITY OF WEST PALM BEACH |
| | |
| | THE FOLLOWING COMMENTS ARE NUMBERED TO CORRESPOND WITH |
| | PREVIOUS REVIEW COMMENTS FOR CONTINUITY. ADDITIONAL NEW |
| | COMMENTS MAY APPEAR AT THE END AS A RESPONSE TO NEW |
| | INFORMATION PROVIDED. |
| | |
| | 1. OK |
| | |
| | 2. FIRE DAMPERS ARE STILL SHOWN ON SEF-2 DUCT AT TRASH |
| | ROOM AND ELEVATOR FOYER WALLS. RATHER THAN ADDRESSING |
| | THE COMMENT BY REPLACING FIRE DAMPERS IN SMOKE EXHAUST |
| | DUCT WITH APPROVED ALTERNATIVE PROTECTION (SUCH AS |
| | COMBINATION FIRE/SMOKE DAMPERS), THE SITUATION IS MADE |
| | WORSE BY THE ADDITION OF ANOTHER FIRE DAMPER IN THE |
| | SMOKE EXHAUST DUCT AT THE TRASH ROOM WALL. SEE FBC,M |
| | 607.2.1: "WHERE THE INSTALLATION OF A FIRE DAMPER WILL |
| | INTERFERE WITH THE OPERATION OF A REQUIRED SMOKE |
| | CONTROL SYSTEM IN ACCORDANCE WITH SECTION 513, APPROVED |
| | ALTERNATIVE PROTECTION SHALL BE UTILIZED." |
| | |
| | 3. A) SMOKE CONTROL RATIONAL ANALYSIS CALLS FOR 2850 |
| | CFM OF MAKE-UP AIR FOR THE 3500 CFM OF SMOKE EXHAUST IN |
| | THE FIRST FLOOR LOBBY AREA. AHU-4 APPEARS TO BE THE |
| | ONLY SOURCE OF MAKE-UP AIR FOR THE FIRST FLOOR LOBBY. |
| | AHU-4 IS SHOWN AS 5 TON ON FLOOR PLAN BUT ON EQUIPMENT |
| | SCHEDULE AHU-4 IS SHOWN AS 3 TONS WITH 1090 CFM |
| | CAPACITY. EVEN A 5 TON AHU WILL NOT TYPICALLY DELIVER |
| | 2850 CFM. B) THE DUCT AND DAMPER DESIGN FOR AHU-4 DOES |
| | NOT HAVE A MECHANISM IN PLACE TO FORCE ALL THE AIR FROM |
| | AHU-4 TO THE FIRST FLOOR LOBBY AREA SHOULD CONDITIONS |
| | CALL FOR EXHAUST IN THE FIRST FLOOR LOBBY AREA. THIS |
| | WOULD SEEM TO BE A NECESSARY COMPONENT OF THE SMOKE |
| | EXHAUST SYYSTEM FOR THE FIRST FLOOR LOBBY IF AHU-4 IS |
| | TO COME CLOSE TO PROVIDING THE REQUIRED CFM OF MAKE-UP |
| | AIR TO THE SPACE BEING EXHAUSTED. C) RATIONAL ANALYSIS |
| | INDICATES ON PAGE 17 THAT THE MAIN LOBBY SHOULD BE |
| | 2-HOUR RATED WHILE THE LIFE SAFETY PLAN (LS.1) SHOWS |
| | LOBBY TO BE 1-HOUR RATED. PG 17 ALSO NOTES THAT LOBBY |
| | PRESSURIZATION DUCTS SHALL BE PROTECTED BY A 2-HOUR |
| | FIRE RESISTIVE RATING FROM THE SOURCE OF OUTDOOR AIR UP |
| | TO THE ENCLOSURE. SEE NOTE #2 ON PG 17. D) IS THERE A |
| | TIME OR CONDITION IN WHICH THE FIRST FLOOR LOBBY WOULD |
| | BE PRESSURIZED RATHER THAN EXHAUSTED? THAT CONDITION IS |
| | NOT COVERED IN THE SEQUENCE ON M0.00. |
| | |
| | 4.ON PG M1.01 PLAN SHOWS A FIRE DAMPER AND FIRE/SMOKE |
| | DAMPER AT 2ND FLOOR SLAB PENETRATION. PLEASE REMOVE |
| | DESIGNATION FOR THE FD AS BOTH ARE NOT REQUIRED AND THE |
| | FD IS PROHIBITED PER FBC,M 607.2.1 (THIS WAS MOST |
| | LIKELY LEFT ON PLANS BY MISTAKE). ALSO, NOTE ON M1.02 |
| | CALLS FOR A 20X18 OPENING IN SLAB FOR A 14X12 |
| | FIRE/SMOKE DAMPER. PLEASE CONSULT FSD INSTALLATION |
| | INSTRUCTIONS FOR MIN/MAX ANNULAR SPACE REQUIREMENTS. |
| | THE SIZE ON PLAN IS LIKELY TO BE WELL OUTSIDE THE |
| | ALLOWANCE PER THE DAMPERS LISTING/INSTRUCTIONS. FBC,M |
| | 607.2 |
| | |
| | 5. NOW THAT AHU-4 IS BEING USED FOR MAKE-UP AIR FOR THE |
| | MAIN LOBBY, THE DOWN-SIZING OF AHU-4 AND DUCT SYSTEM |
| | HAS ADVERSELY AFFECTED THE DESIGN OF THIS PORTION OF |
| | THE SMOKE CONTROL SYSTEM. SEE COMMENT 3 ABOVE AND THE |
| | RATIONAL ANALYSIS REPORT. |
| | |
| | 6. RESPONSE STATES "PROTECTION OF OPENINGS PROVIDED." |
| | HOWEVER, NO PROTECTION IS SHOWN ON PLANS. A LOUVER IS |
| | NOT AN OPENING PROTECTIVE IN A RATED WALL. |
| | |
| | 7. OK |
| | |
| | 8. GENERATOR EXHAUST IS SHOWN DISCHARGING UNDER A |
| | TERRACE FOR AN UPPER FLOOR APARTMENT. ALSO, WHAT IS THE |
| | HEIGHT OF THE EXHAUST DISCHARGE IN RELATION TO |
| | ADJOINING GRADE? |
| | |
| | 9. M1.02 SHOWS A FIRE DAMPER ON THE 30X14 O.A. DUCT AT |
| | THE MECHANICAL ROOM WALL. APPROVED ALTERMATIVE |
| | PROTECTION (SUCH AS A FSD) SHALL BE UTILIZED PER FBC,M |
| | 607.2.1. ALSO, WHAT IS THE PURPOSE OF THE MOTORIZED |
| | DAMPER ON TOP OF AHU-4? WHERE IS THE DUCT SMOKE |
| | DETECTOR? |
| | |
| | 10. M1.02: A LOUVER IS NOT AN OPENING PROTECTIVE IN A |
| | FIRE RATED ASSEMBLY. ALSO, 6X6 DUCT INTO TENANT STORAGE |
| | IS STILL SHOWN TO BE UNPROTECTED. NOTE: DUCTS NOT |
| | REQUIRED TO HAVE DAMPERS IN FIRE RESISTANCE RATED |
| | ASSEMBLIES SHALL COMPLY WITH FBC SEC.712. |
| | |
| | 11. OK |
| | |
| | 12. OK EXCEPT WEST STORAGE ROOM. SEE COMMENT 10 ABOVE. |
| | |
| | 13. OK |
| | |
| | 14. M1.02: 10X6 DUCT IS NOW SHOWN AS 10X10. FIRE |
| | DAMPERS ARE STILL SHOWN IN SMOKE EXHAUST DUCT. SEE |
| | FBC,M 607.2.1: "WHERE THE INSTALLATION OF A FIRE DAMPER |
| | WILL INTERFERE WITH THE OPERATION OF A REQUIRED SMOKE |
| | CONTROL SYSTEM IN ACCORDANCE WITH SECTION 513, APPROVED |
| | ALTERNATIVE PROTECTION SHALL BE UTILIZED." |
| | |
| | 15.A)WHERE COMMUNICATING WITH THE OUTDOORS THROUGH |
| | HORIZONTAL DUCTS, EACH OPENING SHALL HAVE A MINIMUM |
| | FREE AREA OF 1 SQ.IN. PER 2,000 BTU/H PER FBC,FG |
| | 304.6.1. AT 400,000 BTU/H, EACH DUCT REQUIRES A MINIMUM |
| | OF 200 SQ.IN. B) AHERE EXHAUST FANS ARE INSTALLED, |
| | MAKE-UP AIR SHALL BE PROVIDED TO REPLACE THE EXHAUSTED |
| | AIR PER FBC,FG 304.9.1. THIS WOULD BE IN ADDITION TO |
| | THE REQUIRED COMBUSTION AIR. C) COMBUSTION AIR DUCTS |
| | SHOULD NOT SHARE THE SAME LOUVER AND PLENUM PER FBC,FG |
| | 304.11(4). |
| | |
| | 16.OK |
| | |
| | 17. OK |
| | |
| | 18. OK |
| | |
| | 19. NO INFORMATION COULD BE FOUND IN THE A/C EQUIPMENT |
| | SUBMITTALS PROVIDED REGARDING LINE LENGTHS OR ALLOWED |
| | VERTICAL DISTANCES. IF THERE IS NO PUBLISHED LITERATURE |
| | ON THESE SUBJECTS, PLEASE PROVIDE SITE SPECIFIC |
| | ENGINEERING FROM THE MANUFACTURER SHOWING THE |
| | FEASIBILITY OF THIS TYPE OF INSTALLATION. FBC 106.1.2. |
| | NOTE: BASED ON THE CLEARANCE REQUIREMENTS FOR SERVICE |
| | AND VENTILATION AS STATED IN LENNOX INSTALLATION |
| | INSTRUCTIONS, PLEASE VERIFY LAYOUT OF CONDENSERS ON |
| | ROOF MEETS ALL CLEARANCE REQUIREMENTS. SEE LENNOX 13ACD |
| | INSTALLATION INSTRUCTIONS PAGE 3. |
| | |
| | 20. OK |
| | |
| | 21. DAMPERS WERE ADDED PER THE PREVIOUS COMMENT. |
| | HOWEVER, BASED ON THE SMOKE CONTROL RATIONAL ANALYSIS |
| | AND FBC,M 607.5.4, FIRE ANS SMOKE DAMPERS ARE REQUIRED |
| | AT ALL FRESH AIR DUCTS PENETRATIONS OF CORRIDOR WALLS |
| | INTO APARTMENTS. CONTROL OF THESE DAMPERS SHOULD BE |
| | INCLUDED IN THE SEQUENCE OF OPERATIONS. ALSO, PLEASE |
| | VERIFY SMOKE CONTROL SEQUENCE AS SHOWN ON M0.00 IS |
| | COORDINATED WITH THE RATIONAL ANALYSIS AS THERE APPEAR |
| | TO BE SOME DISCREPANCIES BETWEEN THE TWO. PLEASE HAVE |
| | THE ENGINEER OF RECORD FOR THIS PROJECT PROVIDE A SHOP |
| | DRAWING REVIEW AND APPROVE THE ANALYSIS. |
| | |
| | 22. FLOOR PLAN STILL SHOWS 2230 CFM AND RISER DIAGRAM |
| | STILL SHOWS 2600 CFM. THIS DOES NOT APPEAR TO HAVE BEEN |
| | CORRECTED. |
| | |
| | 23. OK |
| | |
| | 24. OK |
| | |
| | 25. BOOSTER FANS WILL NOT BE ACCEPTED BY THIS AHJ |
| | UNLESS THE DRYER MANUFACTURER'S INSTALLATION |
| | INSTRUCTIONS MAKE PROVISIONS FOR THEIR USE. CLOTHES |
| | DRYERS SHALL BE EXHAUSTED IN ACCORDANCE WITH THE |
| | MANUFACTURER'S INSTRUCTIONS PER FBC,M 504.1. |
| | NOTE: 504.6.1 ALLOWS FOR EXTENDED DRYER EXHAUST DUCT |
| | LENGTHS BASED ON MANUFACTURER'S INSTRUCTIONS. PLEASE |
| | SEE EXCEPTION UNDER THIS SECTION: "EXCEPTION: WHERE THE |
| | MAKE AND MODEL OF THE CLOTHES DRYER TO BE INSTALLED IS |
| | KNOWN AND THE MANUFACTURER?S INSTALLATION INSTRUCTIONS |
| | FOR SUCH DRYER ARE PROVIDED TO THE CODE OFFICIAL, THE |
| | MAXIMUM LENGTH OF THE EXHAUST DUCT, INCLUDING ANY |
| | TRANSITION DUCT, SHALL BE PERMITTED TO BE IN ACCORDANCE |
| | WITH THE DRYER MANUFACTURER?S INSTALLATION |
| | INSTRUCTIONS." MANUFACTURER'S INSTRUCTIONS MAY MAKE THE |
| | USE OF BOOSTER FANS UNNECESSARY FOR THE LENGTH OF DUCT |
| | SHOWN ON PLANS. |
| | |
| | 26. OK |
| | |
| | 27. THIS WILL BE CHECKED IN CONJUNCTION WITH COMMENT |
| | #30. |
| | |
| | 28. OK |
| | |
| | 29. COMMENT HAS BEEN ADDRESSED. HOWEVER, IT WAS NOT |
| | NOTED IN PREVIOUS REVIEW THAT THE DRYER EXHAUST DUCT IS |
| | LOCATED IN A RETURN AIR PLENUM. THIS CONDITION IS |
| | PROHIBITED PER FBC,M 504.4 AND 601.3. |
| | |
| | 30. THREE UNITS CHECKED; 3N, 3S AND 6. NONE OF THESE |
| | FLOOR PLANS BALANCE WITH EQUIPMENT SCHEDULE. PLEASE |
| | ADDRESS THIS COMMENT FULLY BEFORE RESUBMITTING PLANS. |
| | |
| | 31. OK |
| | |
| | 32. OK |
| | |
| | 33. OK EXCEPT: SEE COMMENT #3 REGARDING AHU-4 SIZE AND |
| | SMOKE CONTROL. |
| | |
| | 34. OK |
| | |
| | 35. OK |
| | |
| | 36. THIS DETAIL IS SUFFICIENT PENDING FIELD INSPECTOR'S |
| | APPROVAL. THERE MAY BE A CONCERN REGARDING THE LOVER |
| | BEING IN THE AIRFLOW OF THE DRYER EXHAUST AND |
| | COLLECTING LINT. |
| | |
| | 37. S-10 SEC.4 SAYS "A/C STAND BY SUPPLIER." IS THIS A |
| | PRE-ENGINEERED SYSTEM? ALSO, STRUCTURAL ENGINEER'S |
| | WINDLOAD CALCULATIONS HAVE BEEN RECEIVED. HOWEVER, |
| | DETAIL DRAWINGS SHOWING THE INSTALLATION METHOD IN THE |
| | CALCULATIONS REPORT COULD NOT BE FOUND ON PLANS. PLEASE |
| | ALSO INCLUDE INFORMATION REGARDING THE ATTACHMENT OF |
| | THE EQUIPMENT TO THE CURB. FBC 106.1.2 |
| | |
| | 38. M6.01, THIS DETAIL DOES NOT APPEAR TO HAVE BEEN |
| | MODIFIED IN ANY WAY OTHER THAN ITS LOCATION ON THE |
| | PPAGE HAS CHANGED. RATED SHAFTS FOR REFRIGERANT RISERS |
| | HAVE BEEN ADDED TO ARCHITECTURAL PLANS BUT NO SUCH |
| | INFORMATION IS INDICATED ON MECHANICAL PLANS. ALSO, |
| | PROVIDE DETAIL FOR LISTED ASSEMBLY TO BE USED AT |
| | REFFRIGERANT PIPE PENETRATION OF RATED SHAFTS. THE ONES |
| | SHOWN ON M6.02 ARE NOT APPLICABLE TO THIS APPLICATION. |
| | |
| | 39. OK |
| | |
| | 40. THE DETAIL SHOWN ON S-10 SEC.4 IS APPLICABLE TO |
| | NEITHER DUCT SUPPORTS NOT ROOF CURB/RTU ATTACHMENTS. |
| | PLEASE SEE #37 ABOVE. |
| | |
| | 41. THROUGH PENETRATION FIRESTOP DETAIL: THROUGH |
| | PENETRATION FIRE-STOP SYSTEMS USED IN FLOORS SHALL HAVE |
| | AN F AND T RATING OF NOT LESS THAN 1 HOUR BUT NOT LESS |
| | THAN THE REQUIRED RATING OF THE FLOOR BEING PENETRATED |
| | PER FBC 712.4.1.2. ALSO, NOTICE THE DETAIL SHOWN FOR |
| | INSULATED PIPE IS LIMITED TO 1" DIAMETER OR SMALLER. |
| | PERHAPS THIS DETAIL IS A MOOT POINT SINCE RATED SHAFTS |
| | HAVE BEEN ADDED TO ARCHITECTURALS PLANS FOR REFRIGERANT |
| | RISERS. HOWEVER, IF A THROUGH PENETRATION FIRE-STOP |
| | SYSTEM IS NEEDED IN THE BUILDING, A MORE SUITABLE |
| | SYSTEM WILL NEED TO BE SPECIFIED. |
| | |
| | 42. OK |
| | |
| | 43. UNABLE TO LOCATE ANY PLUMBING RESPONSE TO THIS |
| | COMMENT. |
| | |
| | 44. OK |
| | |
| | 45. OK |
| | |
| | 46. NOTE IS STILL SHOWN WITH INCORRECT CODE SECTION IN |
| | THE "ENERGY EFFICIENCY" BOX ON M0.00 |
| | |
| | 47. OK |
| | |
| | 48. AMF-1 ON M1.01 AND M1.02, ALSO GEF 3 AND GEF 4: SEE |
| | FBC,M 504.4 "APPLIANCES LOCATED IN PUBLIC GARAGES OR |
| | OTHER AREAS FREQUENTED BY MOTOR VEHICLES, SHALL BE |
| | INSTALLED A MINIMUM OF 8 FEET (2438 MM) ABOVE THE |
| | FLOOR. WHERE MOTOR VEHICLES EXCEED 6 FEET (1829 MM) IN |
| | HEIGHT AND ARE CAPABLE OF PASSING UNDER AN APPLIANCE, |
| | APPLIANCES SHALL BE INSTALLED A MINIMUM OF 2 FEET (610 |
| | MM) HIGHER ABOVE THE FLOOR THAN THE HEIGHT OF THE |
| | TALLEST VEHICLE. |
| | EXCEPTION: THE REQUIREMENTS OF THIS SECTION SHALL NOT |
| | APPLY WHERE THE APPLIANCES ARE PROTECTED FROM MOTOR |
| | VEHICLE IMPACT AND INSTALLED IN ACCORDANCE WITH NFPA |
| | 88B." |
| | |
| | NEW COMMENTS RELATED TO ENERGY CALCULATIONS: |
| | |
| | A. EXTERIOR WALL TYPE SHOWN ON CALCULATIONS CALL FOR |
| | R-11.9 IN THE INPUT DATA REPORT. HOWEVER, THE EXTERIOR |
| | MASONRY WALL DETAIL ON A9.02 CALLS FOR 1" POLYSTYRENE |
| | W/ MIN. R-5. PLEASE COORDINATE PLANS AND CONSTRUCTION |
| | TYPE TO BE ISED WITH THE INPUT DATA REPORT OF THE |
| | ENERGY CALCULATIONS. NO CONSTRUCTION METHOD IS SHOWN |
| | WHICH WOULD ACHIEVE THE R-11.9 WHICH IS CALLED FOR IN |
| | ENERGY CALCULATIONS. |
| | |
| | B. ROOF TYPE SHOWN IN CALCULATIONS IS "MATAL BLDG ROOF |
| | W/ R-19 BATT." THIS DOES NOT CORRELATE WITH TYPE OF |
| | CONSTRUCTION SHWON ON PLANS. THIS IS NT A METAL |
| | BUILDING AND THERE IS NO BATT INSULATION CALLED FOR ON |
| | PLANS FOR THE ROOF. PLANS CALL FOR A CONCRETE ROOF DECK |
| | WITH A REGID INSULATION BUILT-UP ROOF SYSTEM. PLEASE |
| | COORDINATE PLANS WITH THE INPUT DATA REPORT. |
| | |
| | C. PG M0.00 CALLS FOR MINIMUM R-11 INSULATION AT FLOORS |
| | ABOVE UNCONDITIONED SPACES (SUCH AS THE PARKING |
| | GARAGE). THIS IS NOT SHOWN ON PLANS OR ENERGY |
| | CALCULATIONS. PLEASE CLARIFY. |
