| | ACTION: DENIED |
| | |
| | FBC 2004 CODE FAMILY W/ 2005 AND 2006 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. |
| | |
| | 1. THE REQUEST WAS FOR HOW ROOF CURB FOR RTAC UNITS ARE |
| | TO BE ATTACHED TO BUILDING STRUCTURE. THIS IS NOT |
| | RELATED TO THE PRE-ENGINEERED A/C STANDS FOR THE |
| | CONDENSING UNITS. THE DETAIL ON PG M.107 INDICATES |
| | CURBS ARE TO "ANCHOR OR BOLT TO ROOF STRUCTURE AS REQ'D |
| | BY LOCAL CODES." THERE ARE NO LOCAL CODES WHICH GIVE |
| | DESIGNS FOR STRUCTURAL ATTACHMENTS. THE STRUCTURAL |
| | ENGINEER IS RESPONSIBLE FOR DESIGNING AN ATTACHMENT |
| | METHOD DESIGNED TO MEET WIND LOAD REQUIREMENTS IN |
| | ACCORDANCE WITH FBC 1609. THE STRUCTURAL ENGINEER HAS |
| | PROVIDED A DETAIL FOR FRAMING OF THE ROOF OPENING FOR |
| | THE CURB ON PG S-3, BUT NO INFORMATION WAS PROVIDED FOR |
| | HOW THE CURB IS TO BE ATTACHED TO THIS STEEL FRAMING. |
| | PROVIDE INFORMATION ON TYPE AND SPACING OF |
| | ATTACHMENTS. |
| | |
| | 2. IF THE EQUIPMENT LIFTING LUGS ARE TO BE USED FOR |
| | WIND RESISTANCE, PROVIDE MANUFACTURER?S SUBMITTAL |
| | SHOWING THE LIFTING LUGS CAPABLE OF WITHSTANDING THE |
| | REQUIRED WIND LOADS. IF CABLES ARE TO BE LOOPED OVER |
| | THE UNITS, PROVIDE WIND LOAD CALCULATIONS FOR |
| | STRUCTURAL REVIEW. RESPONSE ALSO REFERENCES NOA FOR A/C |
| | STANDS, WHICH DO NOT RELATE TO ROOF CURB MOUNTING OF |
| | RTAC UNITS. |
| | |
| | 3. OK. |
| | NOTE: MIAMI-DADE NOA?S WHICH ARE UP-TO-DATE DO NOT |
| | REQUIRE LOCAL PRODUCT APPROVAL AS THEY ARE ACCEPTABLE |
| | UNDER THE FLORIDA PRODUCT APPROVAL SYSTEM. |
| | |
| | 4. LOCATION OF CONDENSATE DISPOSAL OK. HOWEVER, |
| | AUXILIARY DRAIN PROTECTION IS STILL REQUIRED. THE |
| | ASSERTION THAT CONDENSATE OVERFLOW FROM A ROOFTOP |
| | PACKAGE UNIT WILL NOT CAUSE DAMAGE TO BUILDING |
| | COMPONENTS IS NOT ACCEPTED. THE UNIT SITS OVER A ROOF |
| | CURB WHICH LEAVES THE UNDERSIDE OF THE UNIT EXPOSED TO |
| | THE INTERIOR OF THE BUILDING. IF THE CONDENSATE DRAIN |
| | PAN OVERFLOWS, THE WATER FROM THE PAN WILL MOST LIKELY |
| | FLOW INTO THE BUILDING WITH THE POTENTIAL TO DAMAGE ANY |
| | BUILDING COMPONENT BELOW IT SUCH AS DUCTWORK, |
| | ELECTRICAL EQUIPMENT, CEILINGS, ETC. AUXILIARY DRAIN |
| | PROTECTION MAY BE PROVIDED BY INSTALLING A WATER LEVEL |
| | DETECTION DEVICE (SUCH AS A FLOAT SWITCH) IN THE |
| | PRIMARY DRAIN PAN OF THE RTAC UNITS. PROVIDE AUXILIARY |
| | OR SECONDARY DRAIN PROTECTION AS REQUIRED BY FBC,M |
| | 307.2.3. |
| | |
| | 5. OK |
| | |
