    Sheetrock Walls

    Guess in an commerical office space with hung ceilings when does the sheetrock stop at the hung ceiling and when does it go all the way up to the slab/or deck? Asking because I guess the only time you would need to firestop your work( if fire rated wall) is if the sheetrock went up past the hung ceiling. Otherwise your conduits/cables would just be supported above the ceilings going from room to room and not penetrate any walls. See attached.

    Hardest job I ever did was drilling a hole in a wall that wasn't there.
    If you don't think too good, don't think too much.

    Some walls slow down fires. Others just hold up paint.

    In my experience this is totally a specification, customer issue. Other posters maybe didn't notice that the walls that penetrate the grid don't go all the way to the deck. For example, the University I work at requires all walls to penetrate the grid, but a high rise I worked in only required 1 hour demising walls to penetrate.


    I know what I don't know, and I know where to go to find it!

    They may go all the way up for sound too. All the way to the floor or roof doesn't necessarily mean rated, but it is a good indicator.
    I can build anything you want if you draw a picture of it on the back of a big enough check.

    There's no substitute for hard work....but that doesn't mean I'm going to give up trying to find one.

    Thanks. So point is hen estimating you should know this so you can properly account for firestopping.
