Constructability reviews should be performed at which stage(s) of design completion?

• A. 30 percent, 60 percent, and 100 percent phases
• B. 10 percent, 30 percent, 60 percent
• C. 50 percent, 75 percent, 100 percent
• D. 20 percent, 40 percent, 60 percent

Answer: (A)

Constructability reviews are used to ensure the design can be built efficiently by examining how the design, materials, sequencing, site constraints, and safety considerations come together in practice. They are most effective when done at multiple key design milestones: once the design has progressed enough to reveal constructability implications, again as more details are developed, and once the design is substantially complete so any remaining issues can be resolved before construction begins. This approach helps catch coordination and sequencing problems early, address fabrication and procurement concerns as the design matures, and verify that the final plan can be built within the project’s schedule and budget. If reviews are skipped in early stages or only done at the end, opportunities to improve constructability are lost and later changes become costly. Therefore, conducting constructability reviews at early, mid, and final design milestones is best.
