Rule Intent
Direct answer: Drywall is often accepted as mixed debris, but moisture and board type can materially change risk and allowed loading strategy.
Use sheet count for speed, then validate moisture assumptions, mixed-load policy, and included tons before booking.
| Factor | Baseline | Implication |
|---|---|---|
| Per-sheet estimate | Range by board type | Use range output instead of single fixed value. |
| Moisture effect | Can move risk tier upward | Dry vs wet assumptions should be compared. |
| Mixed load behavior | Packing inefficiency common | Volume and weight both need margin. |
It can be both, especially when moisture is present.
Board type, water content, and mixed debris affect final tons.
Convert sheets, then run project preset with conservative assumptions.
