Consultants can play a significant part in this effort; these preliminary-level decisions may also result in feedback that calls for refinement or even major change in schematic concepts.

Here t

Decisions made at this level may produce feedback into Level II that will result in changes. However, if Levels I and II are handled with insig

14、 modification) of the more general properties of a total-system design concept, to the fleshing out of requisite elements and details. To summarize: At Level I, the architect must first establish, in conceptual terms, the overall space-form feasibility of basic schematic options. At this stage, coll
