Try this. It should work in theory cos I'm trying to do this too:
For conditionstate AWAITING_CONSTRUCTION
export your building in its first frame of animation only. ie so the animation has not started yet and doesnt have a chance to as its only the first frame. Then in the consitionstate:
ACTIVELY_BEING_CONSTRUCTED
Create another w3d files with your animation in it playing once. Its a long shot and I'm not that familiar with generals ini coding myself but like it said. Works in theory.
