To reply to my own comment, I know that this already can be ~accomplished with, say, revit, I think there are efficiencies to be gained by what they are dount (autodesk should aquire these MOFOs...)

Basically define an elements requirements;

BusStop; Range = X Schedule = Y Frequency = Z FuelReq = AA

etc..

Then you do something like a fixture:

2X4 Fixture; Power = X T24 = Y

Then you setup a standard and a repo for people to post objects to a lib and let them select those things and just plop them on a drawing and the reqs will get calculated.

Although, I was not able to know how they calculated the cost per year for any of their examples... where does that data come from???
