Perhaps, but how useful are those detailed plans and blueprints to the actual consumer of the construction service? They get studied, sure, but I think the customer is still working at the level of features and their expression in the plan, not the plans themselves which are more of an internal tool for the architect and builders. It's true that we lack widely accepted formalized design tools like blueprints, but at the same time it's interesting to note that one of the recognized problems with extensive planning and design documentation in software is that it can't keep up with evolving requirements :). So again, we can't plan because the customer has been taught to think everything is open for discussion at all times.
