SU 8172 was a floor in Room I7, in use earlier than 8170 and 8171, associated with walls 8044 and 8039 (i.e, the same walls definitely or probably associated with 8170/8171). It is likely that the floor continues under 8170 and abuts wall 8038, and probably extended also to 8045 on the west. The floor in this room thus appears to have been repaired or rebuilt a number of times, perhaps suggesting repeated or heavy use.
