Design Development

Design development is the stage where the chosen schematic concept is refined into a more resolved design, typically incorporating structural and systems coordination and more detailed layouts. In public-sector and CM-at-risk workflows, the end of design development is often a milestone for pricing and/or establishing a guaranteed maximum price framework.
