| 2012-10-12 08:23:36 | DENIED BY BUILDING | | | | | | YOUR ATTACHED LETTER IS NOT ACCEPTABLE. THE LETTER IS | | | GIVING THE FASTENER SPACING AT 9" ON CENTER WHICH IS | | | GIVEN IN THE PRODUCT APPROVAL FOR A DESIGN PRESSURE OF | | | -52.5 PSF. THIS WILL WORK FOR THE INTERIOR ROOF ZONE | | | BUT NOT FOR THE PERIMETER AND CORNER AREAS OF THE ROOF. | | | THE CORNER AND PERIMETER AREAS REQUIRE ENHANCED | | | FASTENING BECAUSE THE NEGATIVE PRESSURES IN THESE AREAS | | | ARE IN EXCESS OF THE -52.5 PSF THAT THE 9" O.C. SPACING | | | AT THE 4" LAP AND THE 2 STAGGERED ROWS IN THE CENTER OF | | | THE BASE SHEET IS GOOD FOR. IN ORDER TO GET HIGHER | | | PRESSURES THE NUMBER OF FASTENERS IN THE BASE SHEET | | | NEEDS TO BE INCREASED. | | | | | | TYPICALLY THE LETTER WOULD SPECIFY THAT THE NOA | | | SPECIFIES A DESIGN PRESSURE OF -52.5 PSF WHEN THE BASE | | | SHEET IS FASTENED AT 9" O.C. IN THE 4" LAP AND 9" O.C. | | | IN TWO STAGGERED ROWS IN THE CENTER OF THE SHEET WITH | | | 11 GA. ANNULAR RING SHANK NAILS AND 1-5/8" DIAMETER TIN | | | CAPS. THE ENHANCED FASTENING OF THE FOUR FEET WIDE | | | PERIMETER AND CORNER AREAS AT THE ROOF EDGES WILL BE | | | ACCOMPLISHED BY INCREASING THE FASTENER DENSITY TO 4" | | | O.C. IN THE 4" LAP AN 4" O.C. IN TWO STAGGERED ROWS IN | | | THE CENTER OF THE BASE SHEET. | | | | | | ROBERT MCDOUGAL | | | BLDG. PLAN REVIEW | | | (561)805-6714 | | | [email protected] |
