| | PLEASE ADDRESS THE ITEMS NOTED BELOW: |
| | |
| | 1) COMPLIED. |
| | |
| | 2) COMPLIED. |
| | |
| | 3) THIS COMMENT HAS NOT BEEN ADEQUATELY ADDRESSED. THE |
| | PROPOSED SYSTEM S-12 ON PAGE 21 OF 67 (FL#2533-R22) |
| | REQUIRES A BASE INSULATION LAYER THAT IS MECHANICALLY |
| | FASTENED TO THE STEEL ROOF DECK WITH 1 FASTENER PER 3.2 |
| | SQFT. SPECIFY THE SIZE OF THE INSULATION BOARDS THAT |
| | WILL BE USED ( LENGTH X WIDTH ), PROVIDE CALCULATIONS |
| | THAT SPECIFY THE NUMBER OF FASTENERS PER ISO BOARD (FOR |
| | EACH ROOF ZONE) AND PROVIDE A FASTENER PLACEMENT DETAIL |
| | SHOWING THE REQUIRED LOCATION OF THE FASTENERS PER ISO |
| | BOARD (FOR EACH ROOF ZONE). SEE RAS 117. FBC 107.2.1.2 |
| | ADDITIONAL COMMENTS. |
| | A) I DO SEE ON YOUR DRAWING THAT THE INSULATION PANELS |
| | ARE SPECIFIED AS 2 FT X 8 FT. THERE ARE NOT ANY 2 FT X |
| | 8 FT FIGURES SHOWN IN RAS 117, THEREFORE I WOULD |
| | SUGGEST THAT 2 FT X 4 FT OR 4 FT X 8 FT PANELS BE USED. |
| | I ALSO SEE THAT THE INSULATION IN YOUR DRAWING APPEARS |
| | TO BE IN BETWEEN THE TOP FLANGES OF THE STEEL DECKING. |
| | PLEASE REFER TO FBC 2017 RAS NO. 117 (#4) INSULATION |
| | ATTACHMENT OVER STEEL DECKS. INSULATION PANELS ARE |
| | REQUIRED TO HAVE FULL CONTACT WITH THE TOP FLANGES OF |
| | THE STEEL DECKING. |
| | B) I HAVE REVIEWED YOUR CALCULATIONS AND AGREE THAT |
| | THEY ARE CONSISTENT WITH THE ATTACHMENT AND ENHANCED |
| | FASTENING OF A CONTINUOUS BASE SHEET. HOWEVER, THIS |
| | DOES NOT WORK FOR INSULATION PANELS BECAUSE THEY ARE |
| | NOT CONTINOUS AND AT SOME POINTS YOU WOULD HAVE |
| | FASTENERS IN THE PANEL BUTT JOINTS. (NOTE: ON PAGE 3 OF |
| | YOUR REPORT THE COMPUTED FASTENER SPACING FOR THE |
| | PERIMETER AND CORNER IS REQUIRED TO BE ROUNDED DOWN, |
| | 8.54 INCHES SHOULD BE 8 INCHES AND 4.26 INCHES SHOULD |
| | BE 4 INCHES.) SEE RAS 117 (#3.1) FOR THE REQUIRED |
| | INSTALLATION OF FASTENERS AT INSULATION PANEL EDGES. |
| | C) SEE RAS 117 (#9) FOR THE GENERAL EQUATION TO USE FOR |
| | DETERMINING THE NUMBER OF FASTENERS FOR PERIMETER AND |
| | CORNER AREAS AND SEE FIGURES 1-4 OF THIS APPLICATION |
| | STANDARD FOR COMPLIANT FASTENER SPACING. |
