    I've done it but the columns were spray coated before and the print showed them going there; so stamped by engineers. Three layers of rock sounds like fire protection, look at fire barrier wraps. Not sure what 3 layers of 5/8 or 1/2, or 1" gives in hours.

    Since it's surround a column and there are 3 layers than as David stated you'll need to be conscious of the fire rating of the column. Metal boxes generally have a 2 hour fire rating.
