This maximum <br /> hole size only corresponds to the span length and <br /> location called out. The same hole may not be <br /> acceptable if those parameters are changed. This <br /> fix can be used for other joists matching this criteria <br /> but it is not a design alternate where they can <br /> penetrate all or multiple joists in a unit-this is a repair <br /> detail only. <br /> Please see the attached contractor sketch which <br /> summarizes yesterday's email with maximum hole <br /> criteria and information requiring connectors for <br /> sistered joist repair. <br /> @Dean & David, Nick asked to be cc'd on all such <br /> correspondence, but I will send to you directly for <br /> review and if you can forward it to him if approved, <br /> that would be great. <br /> From: Bradford,Jorian <br /> [mailto:jbradford@walshgroup.com] <br /> Sent:Tuesday,June 20, 2017 11:23 AM <br /> To: Robyn Mah<rmah il:ross.com>; Dean Kralios <br /> 3 , ) <br />
