What is constructability review and when is it performed?

Constructability review evaluates design for ease of construction, identifying potential problems and improvement opportunities before construction. Topics: access and logistics, construction sequences, prefabrication opportunities, standard sizes and materials, tolerance compatibility, maintenance access. Review team includes experienced field personnel, contractors (in design-build), and specialty consultants. Timing: conceptual design (major decisions), detailed design (coordination, details), and pre-construction (final verification). Early constructability input reduces changes, improves schedule, and lowers cost.
