The contractor has <br /> removed this member and installed a new member that is in compliance with the structural drawings. Additionally, <br /> the inspector received a copy of an email from Coffman Engineers, dated 11/11/2022, that would allow welding <br /> on the top and bottom of the new HSS member and increasing the weld size to 1/4".
