How does modular construction change project management approach?

Modular construction shifts work to controlled factory environment. Management changes: (1) Design - earlier completion, tolerance management for transport and fit-up, coordination between shop and site, (2) Procurement - parallel paths for modules and site work, longer fabrication lead times, (3) Scheduling - parallel rather than sequential activities, compressed site duration but total may be similar, (4) Quality - factory QC, pre-installation testing, (5) Logistics - transport permits, heavy lift installation, (6) Cost - different cost structure with higher engineering/fabrication, lower site labor. Requires early contractor involvement and integrated design-fabrication-construction coordination.
