RE: MOUNTAIN VIEW BAPTIST CHURCH STEEPLE e i 4266 RIVER ROAD _ QO ' 0 HICKORY, N C 28602 I� o • ' ATTN: DAVID DEAL VVI MR DEAL; I HAVE INSPECTED THE REFERENCED PROJECT AND REVIEWED THE SHOP DRAWINGS FOR THE NEW STEEPLE. I PROPOSE THAT YOU INSTALL 2 6" X 3.5" X 5/16" X 14' LONG ANGLES UNDER THE TOP CORD OF THE EXISTING TRUSSES. THESE ANGLES WILL SPAN 8 TRUSSES AND WILL BE LOCATED TO MATCH THE HOLDDOWN HOLES OF THE STEEPLE. ADDITIONAL REINFORCING BRACES WILL BE NEEDED AS CAN BE LOCATED ON JOBSITE. I WILL MEET WITH YOU AT THE PROJECT WHEN THE STEEPLE IS DELIVERED AND WE CAN PLACE THE ADDITIONAL BRACES TO SUIT JOB CONDITIONS. PRIOR TO SETTING THE STEEPLE I WILL INSPECT ALL WORK AND SIGN OFF ON YOUR NEW SUPPORT SYSTEM. AFTER THE STEEPLE IS SET I WILL INSPECT FOR COMPLETE INSTALLATION. IF YOU SHOULD HAVE ANY QUESTIONS PLEASE GIVE ME A CALL. THANK YOU, GLEN WALKER, P. E. 125 MPH Wind Loaa Upgrade Steeple 53' -10' 42' Note: All drawings are the property of Piedmont Fiberglass Inc.
