| | ACTION: DENIED |
| | |
| | FBC 2004 CODE FAMILY W/ 2005 SUPPLEMENTS |
| | FBC CH.1 AS AMENDED BY THE CITY OF WEST PALM BEACH |
| | |
| | THE FOLLOWING COMMENTS ARE NUMBERED TO CORRESPOND WITH |
| | PREVIOUS REVIEW COMMENTS AS WELL AS DESIGNER'S WRITTEN |
| | RESPONSES FOR THE PURPOSE OF CONTINUITY. |
| | |
| | NOTE: RESPONSE LETTER FROM GORDON BUCK INDICATES THE |
| | MECHANICAL PROJECT HAS BEEN COMPLETELY REDESIGNED. |
| | THEREFORE, A COMPLETE REVIEW OF THE MECHANICAL SYSTEM |
| | IS NECESSARY AND ADDITIONAL NEW COMMENTS ARE POSSIBLE. |
| | |
| | 1. BATHROOMS HAVE BEEN RECONFIGURED FROM WHAT WAS SHOWN |
| | ON PREVIOUS PLANS. THE WOMEN?S RESTROOM DOES NOT HAVE |
| | ADEQUATE EXHAUST. THE FLOOR PLAN ON PG M.2 NOW SHOWS |
| | THE WOMEN?S RESTROOM WITH 4 WATER CLOSETS. FLOOR PLAN |
| | ALSO SHOWS AN EXHAUST FAN PROVIDING 150 CFM OF EXHAUST. |
| | A MINIMUM OF 50 CFM PER WATER CLOSET IS REQUIRED IN |
| | ACCORDANCE WITH FBC, M TABLE 403.3. AS SUCH THE WOMEN?S |
| | RESTROOM REQUIRES A MINIMUM OF 200 CFM OF EXHAUST. |
| | ALSO, BOTH THE MEN?S AND WOMEN?S RESTROOMS SHOW SUPPLY |
| | AIR IN EXCESS OF THE EXHAUST AIR. ALL AIR SUPPLIED TO |
| | THE RESTROOMS SHALL BE EXHAUSTED IN ACCORDANCE WITH |
| | FBC, M 403.2.1. |
| | |
| | 2. OUTSIDE AIR CALCULATIONS ARE NOT IN CONFORMANCE WITH |
| | THE REQUIREMENTS OF TABLE 403.3. THE FOLLOWING ARE |
| | EXAMPLES ONLY. THE CALCULATIONS FOR THE ENTIRE BUILDING |
| | SHOULD BE CHECKED FOR ACCURACY PRIOR TO RESUBMITTAL. |
| | -AHU #1: THIS UNIT SERVES TWO CONFERENCE ROOMS AND A |
| | MEETING HALL. FBC, M TABLE 403.3 PUTS THE OCCUPANT LOAD |
| | IN THESE AREAS AT 50 PEOPLE PER 1000 SQUARE FEET. WITH |
| | ONE OF THE CONFERENCE ROOMS DIVIDED IN HALF (BECAUSE IT |
| | IS SERVED BY AHU 1 AND AHU 3, THE TOTAL SQUARE FEET OF |
| | THESE THREE AREAS IS 402 SF. AT 50/1000 THESE AREAS |
| | HAVE AN OCCUPANT LOAD OF 20 PEOPLE WITH AN OUTSIDE AIR |
| | RATE OF 20 CFM PER PERSON FOR A TOTAL REQUIRED OUTSIDE |
| | AIR VOLUME OF 400 CFM. |
| | -AHU #2 AND AHU #4: THE OCCUPANT LOAD OF THE ASSEMBLY |
| | AREAS ARE TO BE CALCULATED AT 150 PEOPLE PER 1000 |
| | SQUARE FEET. WHERE SPACES HAVING DIFFERENT VENTILATION |
| | RATE REQUIREMENTS ARE SERVED BY A COMMON VENTILATION |
| | SYSTEM, THE RATIO OF OUTDOOR AIR TO TOTAL SUPPLY AIR |
| | FOR THE SYSTEM SHALL BE DETERMINED BASED ON THE SPACE |
| | HAVING THE LARGEST OUTDOOR AIR REQUIREMENT IN |
| | ACCORDANCE WITH FBC, M 403.3.2. THEREFORE, THE ENTIRE |
| | SPACE SERVED BY AHU #2 AND AHU #4 SHALL BE CALCULATED |
| | AT THE RATE STATED ABOVE. ACCORDING TO THE TABLE ON PG |
| | M.1, THESE UNITS SERVE A COMBINED SPACE OF 4665 SQUARE |
| | FEET FOR A TOTAL OCCUPANT LOAD OF 700 PEOPLE. AT A RATE |
| | OF 15 CFM PER PERSON THE TOTAL REQUIRED VOLUME OF |
| | 10,500 CFM. AHU #2 AND AHU #4 ARE NOT CAPABLE OF |
| | SUPPLYING THESE QUANTITIES EVEN AT 100% OUTSIDE AIR. |
| | NOTE: THERE ARE DIFFERENT DESIGN PARAMETERS AND SYSTEM |
| | CONFIGURATIONS WHICH COULD SIGNIFICANTLY REDUCE THE |
| | AMOUNT OF OUTSIDE AIR REQUIRED FOR THESE SPACES. THESE |
| | NUMBERS ARE BASED SOLELY ON THE INFORMATION AND SYSTEMS |
| | SHOWN ON THE PLANS. PLEASE CALL IF THE DESIGNERS WOULD |
| | LIKE TO DISCUSS ALTERNATIVES OR OPTIONS. |
| | |
| | 3. AHU #2, AHU #4 AND PU #6 AT 5 TONS ARE CAPABLE OF |
| | PRODUCING CFM IN EXCESS OF 2,000 AND THEREFORE A FAN |
| | SHUT-DOWN BY SMOKE DETECTOR IS STILL REQUIRED ON THESE |
| | SYSTEMS IN ACCORDANCE WITH FBC, M 606.2.1. |
| | |
| | 4. OK. FLOOR PLAN NOW SHOWS DUCTED RETURNS, THUS |
| | ELIMINATING PLENUM CLOSETS. |
| | |
| | 5. PG M.3: PRIVATE BATH IS STILL MISSING EXHAUST AS |
| | REQUIRED IN ACCORDANCE WITH FBC, M TABLE 403.3. |
| | |
| | 6. A) CONDENSING UNITS SHOWN ON ROOF INSTALLED ON |
| | EXISTING A/C STANDS. AS STATED IN PREVIOUS REVIEW, WORK |
| | DONE WITHOUT A PERMIT WILL NOT BE CONSIDERED EXISTING. |
| | THEREFORE, PRE-ENGINEERED A/C STANDS ARE REQUIRED TO |
| | HAVE PRODUCT APPROVAL IN ACCORDANCE WITH FAC RULE |
| | 9B-72. PROVIDE PRODUCT APPROVAL DOCUMENTATION, REVIEWED |
| | AND APPROVED IN WRITING BY THE PROJECT DESIGN |
| | PROFESSIONAL IN ACCORDANCE WITH FBC 106.3.3. ALSO, PU |
| | #6 IS INSTALLED ON A ROOF CURB. PROVIDE DETAIL WITH |
| | WIND LOAD CALCULATIONS FOR BUILDING PLAN REVIEW TO SHOW |
| | HOW CURB IS TO BE ATTACHED TO STRUCTURE AND HOW UNIT IS |
| | TO BE ATTACHED TO CURB. MECHANICAL EQUIPMENT, |
| | APPLIANCES AND SUPPORTS THAT ARE EXPOSED TO WIND SHALL |
| | BE DESIGNED AND INSTALLED TO RESIST THE WIND PRESSURES |
| | ON THE EQUIPMENT AND THE SUPPORTS AS DETERMINED IN |
| | ACCORDANCE WITH THE FLORIDA BUILDING CODE, BUILDING PER |
| | FBC, M 301.13. |
| | NOTE: THIS REQUIREMENT INCLUDES THE ROOFTOP PACKAGE |
| | UNIT ITSELF, WHICH MUST ALSO BE DESIGNED AND TESTED TO |
| | WITHSTAND WIND PRESSURES AS REQUIRED BY THIS SECTION. |
| | B) CU #4, CU #5 AND PU #6 ARE LOCATED ON SECOND STORY |
| | ROOF. HOW IS THIS EQUIPMENT TO BE ACCESSED FOR SERVICE? |
| | WHERE EQUIPMENT AND APPLIANCES REQUIRING ACCESS ARE |
| | INSTALLED ON ROOFS OR ELEVATED STRUCTURES AT A HEIGHT |
| | EXCEEDING 16 FEET, SUCH ACCESS SHALL BE PROVIDED BY A |
| | PERMANENT APPROVED MEANS OF ACCESS, THE EXTENT OF WHICH |
| | SHALL BE FROM GRADE OR FLOOR LEVEL TO THE EQUIPMENT AND |
| | APPLIANCES? LEVEL SERVICE SPACE IN ACCORDANCE WITH FBC, |
| | M 306.5. PLEASE SEE THIS CODE SECTION FOR ADDITIONAL |
| | SPECIFIC REQUIREMENTS. PROVIDE DETAIL ON PLANS SHOWING |
| | COMPLIANCE WITH THIS SECTION. |
| | |
| | 7. THIS COMMENT WAS NOT ADDRESSED. ALSO, ROOFTOP |
| | PACKAGE UNIT REQUIRES AUXILIARY DRAIN PROTECTION IN |
| | ACCORDANCE WITH FBC, M 307.2.3. A FLOAT SWITCH INSIDE |
| | THE UNIT ON THE PRIMARY DRAIN PAN WILL MEET THIS |
| | REQUIREMENT. |
| | |
| | 8. COMPLETION OF PROCEDURES DEMONSTRATING COMPLIANCE |
| | WITH THIS CODE FOR COMMERCIAL BUILDINGS SHALL BE SIGNED |
| | AND SEALED BY AN ARCHITECT OR ENGINEER LICENSED TO |
| | PRACTICE IN THE STATE OF FLORIDA IN ACCORDANCE WITH FBC |
| | 13-103.1.1.1. |
| | |
| | NEW COMMENT: GENERAL NOTE #2 ON PG M.1 STATES THAT |
| | OUTSIDE AIR IS PROVIDED BY OARTU 1 & 2. THIS NOTE IS |
| | NOT APPLICABLE TO THIS JOB AT THIS TIME AND SHOULD BE |
| | REMOVED FROM PLANS. FBC 106.1.1. |
