How to place foundation without triggers (It's possible!!!)

AOHH writes: In AoK:TS, DiGiT stated that a unit's "Unknown 2" variable always equal to "2". However, as it turns out; this so called "Unknown" variable is in fact the building stage, as follows:
0 = Foundation
1 = Being built
2 = Standing

Whoever is re-modifying the AoK:TS source code, should add this in, because it currently has no field to allow such specification.

I have yet to find out what "Unknown 1" variable is used for.
