Please see the attached file. I have a 8" conc exterior wall with 3 5/8" met. stud and 5/8" gyp bd. The column enclosure is 2 1/2" met stud with 5/8" gyp.
I am trying to remove 3 5/8" stud and gyp bd in the chase.
I was told by some people saying add wall type (8"conc. wall) and replaced where we want to get rid of the stud and gypsum wall. Is there a different way to accomplish this without using two wall types? Is there any method to notch a portion of wall? Any help would be much appreciated.
