Delete buildings?

So I server I join on a regular basis was hacked majorly. Someone spawned the tec building numerous times everywhere... Is there any way to delete these buildings using any specific hack tool or even using admin rights? Any ideas?

Sorry but the only way is to reset all map data.

Yes i have my server with custum buildings set by me , open or database with navicat or mysql go to dayz list then objects should have the name of build and is position that delete it and done

Happened on a server I frequent also. They reset the server (everything).
