The NCIDQ IDPX exam tests the designer’s understanding of the design development phase, which involves refining the schematic design into more detailed and finalized drawings and selections to prepare for the contract document phase.
Option A (Preliminary floor plan, elevations, and details):Preliminary floor plans, elevations, and details are typically part of the schematic design phase, not design development. In design development, these elements are further refined and finalized, not preliminary.
Option B (Bubble diagrams, scale models, and finish schedule):Bubble diagrams are used in the programming or early schematic design phase to define spatial relationships, notin design development. Scale models may be used but are not a primary deliverable, and a finish schedule is too detailed for this phase—it is typically finalized in the contract document phase.
Option C (Finalized floor plans, 3-D drawings, and finish samples):This is the correct choice. During the design development phase, the designer presents finalized floor plans (refined from schematic design), 3-D drawings (to communicate the spatial design to the client), and finish samples (to confirm material selections). These deliverables reflect the phase’s focus on finalizing the design and preparing for construction documents.
Option D (Criteria matrix, orthographic drawings, and blocking diagrams):A criteria matrix and blocking diagrams are part of the programming or schematic design phase, used to establish requirements and spatial layouts. Orthographic drawings (e.g., plans, elevations) are developed throughout the process, but this option’s combination with earlier-phase deliverables makes it incorrect.
Verified Answer from Official Source:
The correct answer is verified from NCIDQ’s official study materials on the design development phase and deliverables.
“In the design development phase, the designer presents finalized floor plans, 3-D drawings, and finish samples to communicate the refined design intent and prepare for the contract document phase.” (NCIDQ IDPX Study Guide, Design Development Section)
The NCIDQ IDPX Study Guide specifies that finalized floor plans, 3-D drawings, and finish samples are key deliverables during the design development phase, as they refine the schematic design and prepare the client for the next phase. This aligns with Option C, making it the correct answer.
Objectives:
Understand deliverables in the design development phase (NCIDQ IDPX Objective: Design Development).
Apply design refinement to prepare for contract documents (NCIDQ IDPX Objective: Contract Documents).
