construction-waste reduction from modular construction vs stick-built (78.8% average across 59 building cases) — not a general factory-prefab figure

| Caveat | Average overall onsite construction-waste reduction for MODULAR construction vs stick-built, across 59 building cases. The study distinguishes modular from other non-modular offsite methods, so this is not a general factory-prefab figure. |
