Determines whether or not a BuildingType can be placed on any cell of the map, ignoring Buildable and pre-existing objects within the foundation. Such a building can be placed on any terrain and even if the foundation is occupied by units or structures, however when constructed, it still has to obey its' Adjacent setting. The feature is used for rare pre-placed map structures (such as the dams in Tiberian Sun) and is not intended for use with structures that can actually be built by players in-game.
