Were not that far from mostly automated architectural design. This is from an article(in 2005) about an automated system to design custom metal buildings[1]: "The automated engineering done with the EDS, which is still being extended, is close to 98% complete for the simplest buildings and 50-60% complete for the most complex buildings. The tasks that are remaining are not automated, as they are either highly custom, or occur so seldom that the added knowledge capture for these few occurrences does not justify the automation cost." There's also a similar tool for design of private construction[2].I think the software even understand civil codes.
