Average onsite construction-waste reduction for modular construction versus stick-built (78.8%), from a study of 59 selected building cases covering modular and nonmodular offsite approaches; not a data-center allowance
78.8%observed
| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Caveat | The 59 cases include modular and other offsite methods; 78.8% is the modular result relative to stick-built. It is a building-sector average, not a general factory-prefab figure and not a data-center waste allowance. |
