This should be achievable but they may need to sister in additional stud sections (back•to•back with the <br /> existing) in some locations so Ihey can mainlain the required edge dislances. The added sections of stud do not <br /> need to be continuous Qhey can be discontinued at the blocking and just short of the top and bo8om tracks if need <br /> be), however they wilt need tu be fastened to the existing stud wilh (2)k8 screws (pairs) at B"maz spacing up the <br /> stud. <br /> David 7.Webiter� PE SE I Structural Eny�ncer <br /> KPFF Con.ultlnp Enylneers <br /> 1601 Fdth Avenue, Suite 1600 <br /> Scattic, Washington 9tl101 <br /> O: (206) 622�5822 0: (206) 92G�0570 <br /> F.
