I am trying to figure out whether wall is load bearing or not. I am in 2nd floor of 3 storey condominium building.
To figure out which way joists run, I cut rectangle in ceilling near the wall. I can see metal piece behind ceilling drywall as shown in first picture ( along the side of rectangle, facing bottom right corner of picture). That is definitely not duct work. I placed my cellphone inside and took its picture along it's length. (2nd picture)
I did find 2x4 or 2x6 running parallel to the wall, around 24 inch away but its wider side is facing toward sky. Is that joist ? I thought joists are placed wider side facing sideways and shorter side facing sky.
