| | DENIED BY BUILDING |
| | PLEASE ADDRESS THE ITEMS NOTED BELOW: |
| | |
| | 1) THE ENGINEER USED AN EFFECTIVE WIND AREA OF 21.2 |
| | SQUARE FEET TO DETERMINE THE COMPONENT & CLADDING ROOF |
| | PRESSURES. THE TRIBUTARY AREA OF THE FASTENERS FOR THE |
| | ROOFING MATERIAL IS LESS THAN 10 SQUARE FEET. ASCE 7-10 |
| | USES AN EFFECTIVE AREA OF 10 SQUARE FEET WHEN A |
| | CLADDING FASTENER HAS A TRIBUTARY AREA OF LESS THAN 10 |
| | SQFT. PLEASE PROVIDE CLARIFICATION AS TO WHY THE |
| | ENGINEER USED 21.2 SQFT AS THE EFFECTIVE WIND AREA. FBC |
| | 107.2.1 |
| | |
| | 2) THE ROOFING SYSTEM (SC-127) THAT WAS SPECIFIED FROM |
| | THE CARLISLE SURE-WELD TPO ROOF SYSTEM PRODUCT APPROVAL |
| | HAS A MAXIMUM DESIGN PRESSURE OF -60 PSF. THIS DESIGN |
| | PRESSURE IS NOT ADEQUATE FOR THE PERIMETER AND CORNER |
| | ROOF AREAS. SUBMIT TWO SETS OF SIGNED AND SEALED RAS |
| | 117 CALCULATIONS FOR ENHANCED FASTENING AT THE |
| | PERIMETER AND CORNER AREAS IN ACCORDANCE WITH |
| | LIMITATION NUMBER 5.7 ON PAGE 5 OF 6 OF THE PRODUCT |
| | APPROVAL (FL14083-R14). FBC 1604.2 |
| | |
| | 3) THE WORK DESCRIPTION ON THE PERMIT APPLICATION LISTS |
| | THIS PROJECT AS A RE-ROOF AND PAGE 2 OF THE ROOFING |
| | "FORM 110" INDICATES THAT THIS IS A RECOVER. PLEASE |
| | CLARIFY. FBC 107.2.1 |
| | |
| | 4) IF THIS IS A RECOVER, LIMITATION NUMBER 5.6 ON PAGE |
| | 5 OF 6 OF THE PRODUCT APPROVAL (FL14083-R14), STATES |
| | "FOR RECOVER INSTALLATIONS, THE EXISTING ROOF SHALL BE |
| | EXAMINED IN ACCORDANCE WITH FBC 1510." YOU WILL ALSO BE |
| | REQUIRED TO HAVE THE ROOF INSPECTED BY THE CITY |
| | BUILDING INSPECTOR BEFORE STARTING THE RECOVER. FBC |
| | 110.3 |
| | |
| | 5) ADDITIONAL INFORMATION IS REQUIRED FOR THE SKYLIGHT |
| | INSTALLATION. BASED ON AERIAL PHOTOGRAPHS THERE IS 16 |
| | SKYLIGHTS THAT ARE GROUPED TOGETHER IN AN ARRAY AT THE |
| | CENTER OF THE ROOF. THE PRODUCT APPROVAL THAT WAS |
| | SUBMITTED IS FOR ATTACHING TO WOOD FRAMING MEMBERS AND |
| | THIS ROOF HAS METAL FRAMING. PLEASE SUBMIT SIGNED AND |
| | SEALED ENGINEERED DRAWINGS OF THE EXISTING ROOF |
| | STRUCTURE WITH ALL DIMENSIONS SHOWING HOW THE SKYLIGHTS |
| | WILL BE ATTACHED TO THE METAL FRAME WORK. PROVIDE ANY |
| | CALCULATIONS AND ANY OTHER DATA NECESSARY TO SHOW THAT |
| | THE PROPOSED INSTALLATION WILL MEET THE WINDLOAD |
| | REQUIREMENTS. THE ENGINEER OF RECORD IS REQUIRED TO |
| | REVIEW AND APPROVE THE PRODUCT APPROVAL FOR THE |
| | SKYLIGHTS. FBC 107.2.1.2 & 107.2.1.3 |
