| | |
| | THE RAS117 CALCULATIONS ARE NOT ACCEPTABLE FOR THE |
| | FOLLOWING REASONS: |
| | 1) THIS PRODUCT APPROVAL IS NOT A MIAMI-DADE NOTICE OF |
| | ACCEPTANCE. THIS IS A FLORIDA (DBPR) PRODUCT APPROVAL. |
| | IN ORDER TO AVOID CONFUSION, REMOVE THE NOA FROM THE FL |
| | 1654-R20 FROM THE ENGINEER'S LETTER. FBC 107.2.1 |
| | |
| | 2) THE PAGE NUMBER FROM THE FLORIDA PRODUCT APPROVAL IS |
| | INCORRECTLY SPECIFIED AS SHEET 17 OF 58. THE SYSTEM |
| | NUMBER IS SPECIFIED ON THE ENGINEER'S LETTER AS W-94, |
| | WHICH IS LOCATED ON PAGE 18 OF 55. FBC 107.2.1 |
| | |
| | 3) THE REQUIRED UPLIFT PRESSURES FOR THE ROOF ZONES IS |
| | NOT SPECIFIED ON THE ENGINEER'S LETTER. THE WIND SPEED, |
| | EXPOSURE CATEGORY AND MEAN ROOF HEIGHT ARE ALSO NOT |
| | PROVIDED. FBC-R301.2.1 |
| | |
| | 4) THE W-94 ROOFING SYSTEM HAS A MAXIMUM DESIGN |
| | PRESSURE OF -67.5 PSF. THE LETTER STATES THAT THE |
| | MAXIMUM DESIGN PRESSURE IS -60 PSF. FBC 107.2.1 |
| | |
| | 5) THE W-94 ROOFING SYSTEM IS A PROPRIETARY SYSTEM AND |
| | REQUIRES POLYGLASS APP BASE FOR THE BASE SHEET. THE |
| | OTHERS LISTED IN THE LETTER CAN NOT BE USED WITH THIS |
| | SYSTEM. FBC 107.2.1 |
| | |
| | 6) THIS SYSTEM REQUIRES FOUR (4) EQUALLY SPACED |
| | STAGGERED CENTER ROWS AND THE LETTER ONLY SPECIFIES |
| | THREE (3). FBC 107.2.1 |
| | |
| | 7) THE PERIMETER AND CORNER AREA FASTENING DOES NOT |
| | SPECIFY THE LAP OR THE NUMBER OF CENTER ROWS. FBC |
| | 107.2.1 |
| | |
| | 8) SUBMIT TWO SETS OF THE ACTUAL RAS 117 CALCULATIONS |
| | THAT WERE USED TO DETERMINE THE ENHANCED FASTENING. FBC |
| | 107.2.1.3 |
