At this stage we elaborate on the master plan concepts, detailing everything from individual rivets to paint colors. Conceptual artwork evolves into schematic and construction-ready drawings, specifying precisely what will be built, where, and how. Technologies, materials and media are selected to fully realize the design, appearance, and theming intent. The outcome is a set of documents that outline the exact fabrication, construction and production details of the project. Functional and operational requirements are also finalized during this phase.
