📊 Calculation logic: structure + demo type combo
Our engine uses base rate per sq ft, then applies demolition type multiplier (emergency +32%, partial +12% complexity, interior high labor low machinery), plus hazard/urban/salvage modifiers. Debris automatically adjusts for partial/interior demolition.
❓ Frequently Asked Questions
How does demolition type affect cost?
Full demo = normal; Partial adds complexity factor; Interior reduces machinery & debris; Emergency includes rush premium (32%).
Why does debris change for partial demo?
Partial demolition typically removes only part of the structure, we apply debris reduction factor ~45% of total volume.
What does Advanced Mode do?
Shows length/width/depth inputs for precise volume, full formula breakdown, and manual rate override.
