\rr <br /> system,the work would have been sufficient to withstand the required loads. In fact,each half of <br /> the rafter span could have been supported with one additional member for a total of two, rather <br /> than the five members that were installed. <br /> The rafters were beefed up at No's 4,6,8,and 10 and are now configured as shown in Section C. <br /> A 2x6 was laid on top of the additional 2x6 rafters and spans between the above rafters and <br /> supports rafters 5, 7,and 9. <br /> However,rafters at 2,3, II, 12, 13,and 14 also require this extra support. Rafter 14,which <br /> attaches to the south face of the north wall,could be amended by adding three nails(3"x <br /> 0.13 1"±)as was used to connect the additional 2x6's;or,blocking could be installed below the <br /> No. 14 rafter with three nails as listed above. <br /> To remedy the situations at the north and south ends of the building,the following additions need <br /> to be installed: <br /> 1) At rafters 2 and 12,install member:identical to Sections C. <br /> 2) At rafter 14,install members identical to Sections C,but without any vertical <br /> members,since this is being attached to the already existing 2x4 wall studs. <br /> %at 3) Extend new flat 2x6 puffins from rafter 1 to 4 and from 10 to 14. These do not have <br /> to be at the exact midpoint but should be near the center of the rafter and must be blocked <br /> to support the existing rafters. <br /> 4) Nail patterns and nail sizes as used to add new members are sufficient. Repeat on <br /> required additional new members. <br /> If you,or the contractor,have any questions,please feel free to contact me. <br /> Sincerely, ?Sop <br /> U acm c.e si Oeurs74\„"wctett <br /> -Corbe Boatwright,ofRe PE <br /> City Engineer of Record,City of Donald Q Sir 910 `Sr <br /> BO►T° <br /> Renewal Date: December 31,2017 <br /> [ Enclosures: Calculations <br /> Rafter Diagram &Index <br /> Old City Hall Rog Evaluohw 8-152016 <br /> Page 2 of. <br />
