| | |
| | DENIED BY BUILDING |
| | PLEASE ADDRESS THE ITEMS NOTED BELOW: |
| | |
| | 1) PROVIDE AREA TABULATIONS FOR THE CONDITION SPACES |
| | AND THE UN-CONDITIONED SPACES. THE PLANS DIFFER FROM MY |
| | CALCULATIONS. I HAVE DETERMINED THE AREA OF CONDITIONED |
| | SPACE AS 1813 SQFT AND THE AREA OF THE UN-CONDITIONED |
| | SPACE (COVERED PORCHES AND ENTRY) AS 317 SQFT. FBC |
| | 107.2.1 |
| | |
| | 2) (PREVIOUS COMMENT.) SHOW COMPLIANCE WITH FBC-R318.5 |
| | CONDENSATE LINES, IRRIGATION/SPRINKLER SYSTEM RISERS |
| | FOR SPRAY HEADS, AND ROOF DOWNSPOUTS SHALL DISCHARGE AT |
| | LEAST 1 FOOT (305 MM) AWAY FROM THE STRUCTURE SIDEWALL, |
| | WHETHER BY UNDERGROUND PIPING, TAIL EXTENSIONS OR |
| | SPLASH BLOCKS. GUTTERS WITH DOWNSPOUTS ARE REQUIRED ON |
| | ALL BUILDINGS WITH EAVES OF LESS THAN 6 INCHES (152 MM) |
| | HORIZONTAL PROJECTION EXCEPT FOR GABLE END RAKES OR ON |
| | A ROOF ABOVE ANOTHER ROOF. THE RESPOSE WAS TO PROJECT |
| | THE SCUPPERS 6" PAST THE EXTERIOR WALL. THIS IS NOT AN |
| | ACCEPTABLE ALTERNATIVE. UNLIKE A SIX INCH ROOF EAVE |
| | WHICH WILL DISTRIBUTE THE RAIN WATER RUN OFF FROM THE |
| | ROOF, THE RAIN WATER WILL BE FUNNELED TO THE SCUPPERS |
| | AND THE CONCENTRATED DISCHARGE WILL ERODE THE SOIL. THE |
| | PRIMARY SCUPPERS WILL NEED TO HAVE CONDUCTOR HEADS AND |
| | DOWN SPOUTS. |
| | |
| | 3) (PREVIOUS COMMENT.) PROVIDE STRUCTURAL DETAILS FOR |
| | THE LEDGERS THAT ARE SUPPORTING THE ROOF TRUSSES. FBC-R |
| | 301.1 |
| | |
| | 4) (PREVIOUS COMMENT.) PROVIDE THE ROOF UPLIFT VALUES |
| | FOR A 10 SQFT EFFECTIVE WIND AREA. THE ROOF DESIGN |
| | PRESSURES IN THE TABLE ON SHEET S-3 ARE INCORRECT. THE |
| | DESIGN PRESSURES FOR THE FLAT ROOF WITH A 132 MPH VASD |
| | WINDSPEED, A 15' OR LESS MEAN ROOF HEIGHT AND EXPOSURE |
| | C SHOULD BE AS FOLLOWS: +15.4, -37.9 PSF FOR ROOF ZONE |
| | 1, +15.4, -63.6 PSF FOR ROOF ZONE 2 AND +15.4, -95.7 |
| | PSF FOR ROOF ZONE 3. FBC-R301.2.1 |
| | |
| | 5) (PREVIOUS COMMENT.) PROVIDE SCUPPER SIZING |
| | CALCULATIONS. FBC 107.2.1 & FBC- PLUMBING 1106.7 SHOW |
| | ALL CALCULATIONS ON THE PLANS. INCLUDE THE ROOF AREAS |
| | OF THE ENTRY TOWER THAT DRAIN ONTO THE LOWER ROOF AND |
| | ONE HALF THE AREA OF THE WALLS OF THE WALLS OF THE |
| | TOWER THAT ARE ADJACENT TO THE LOWER ROOF. |
| | |
| | 6) PROVIDE DETAILS OF THE ENCLOSED SCUPPERS WITH |
| | DIMENSIONS. THE PRIMARY DRAIN SCUPPERS ARE REQUIRED TO |
| | BE LOCATED LEVEL WITH THE LOWEST PORTION OF THE ROOF. |
| | FBC 107.2.1 |
| | |
| | 7) (PREVIOUS COMMENT.) R903.4.1 OVERFLOW DRAINS AND |
| | SCUPPERS. WHEN OTHER MEANS OF DRAINAGE OF OVERFLOW |
| | WATER IS NOT PROVIDED, OVERFLOW SCUPPERS SHALL BE |
| | PLACED IN WALLS OR PARAPETS NOT LESS THAN 2 INCHES (51 |
| | MM) NOR MORE THAN 4 INCHES (102 MM) ABOVE THE FINISHED |
| | ROOF COVERING AND SHALL BE LOCATED AS CLOSE AS |
| | PRACTICAL TO REQUIRED VERTICAL LEADERS OR DOWNSPOUTS OR |
| | WALL AND PARAPET SCUPPERS. AN OVERFLOW SCUPPER SHALL BE |
| | SIZED IN ACCORDANCE WITH THE FLORIDA BUILDING CODE, |
| | PLUMBING. SECONDARY (EMERGENCY) ROOF DRAINS SHALL ALSO |
| | COMPLY WITH FBC PLUMBING SECTION 1108.3 SIZING OF |
| | SECONDARY DRAINS. SECONDARY (EMERGENCY) ROOF DRAIN |
| | SYSTEMS SHALL BE SIZED IN ACCORDANCE WITH SECTION 1106 |
| | BASED ON THE RAINFALL RATE FOR WHICH THE PRIMARY SYSTEM |
| | IS SIZED IN TABLES 1106.2(1), 1106.2(2), 1106.3 AND |
| | 1106.6. SCUPPERS SHALL BE SIZED TO PREVENT THE DEPTH OF |
| | PONDING WATER FROM EXCEEDING THAT FOR WHICH THE ROOF |
| | WAS DESIGNED AS DETERMINED BY SECTION 1101.7. SCUPPERS |
| | SHALL HAVE AN OPENING DIMENSION OF NOT LESS THAN 4 |
| | INCHES (102 MM). THE FLOW THROUGH THE PRIMARY SYSTEM |
| | SHALL NOT BE CONSIDERED WHEN SIZING THE SECONDARY ROOF |
| | DRAIN SYSTEM. |
| | |
