[Spell] Is there a rawcode for the Build ability?

[Carnerox]

I've been searching around to find a way to disable the Build ability, like you can with 'Amov' and 'Aatk' with BlzUnitDisableAbility, but to no avail. Is there a way to find the rawcode for it, or disable it (for a duration) without having to use silence (I don't want to disable other abilities) to use the "disabled" effect?

Thanks.

You can find these in the file Units\AbilityData.slk.
