Thanks for the clarification!
Putting "Construction Simulation" in the search tab of the standard ArchiCAD 11 Help yields no result, and putting it in Google suggests an expensive program from Synchro:

I've downloaded the Goodies, and will give it a try this evening. Hopefully it's not too hard, or maybe I can find some instructions now that I've got the proper add-on program...
Thanks!
