Just so you know, you only need to transform the construction site un a weapon rack and it will disapear (or be breakable if fixed).
No admin, no changemap needed... just 2 guys puting on some construction material, throw them on the construction site (wich as been switched to weapon rack with the use key first) and the problem is fixed.
I dont say it should not be banable to put down a csite but there is a way to deal with it and there it is.
