Constructibility reviews are typically conducted during which phase of a project?

• A. Post-construction
• B. Pre-construction or design phase
• C. During occupancy
• D. After commissioning

Answer: (B)

Constructibility reviews are done when the design is still being developed to make sure it can be built efficiently with available methods, materials, and crew. Conducting this review during the design or pre-construction phase brings in the builder’s perspective early, so issues like hard-to-construct details, sequencing conflicts, access constraints, or long-lead items can be identified and addressed before the design is locked. Addressing constructibility early helps cut change orders, shorten the schedule, and refine costs because changes are cheaper and easier to implement while drawings are still flexible. It also improves coordination among trades, informs construction methods, sequencing, safety planning, and procurement strategies, and leads to more accurate project estimates. If constructibility problems are discovered later—during construction, occupancy, or after commissioning—making changes becomes costly, disruptive, and time-consuming, often affecting already-built portions of the project.
