Full-Building Demolition Debris Calculator
Estimate debris weight, volume and nominal dumpster-load equivalents for the complete demolition of a building.
Project details
Enter the footprint, number of stories and building type for a full-building demolition.
How this estimate works
This tool is specifically for complete building demolition. DebrisPilot multiplies total floor area by a demolition planning generation factor for the selected building type, then converts the estimated weight to volume using a mixed construction-and-demolition debris density factor.
The generation factors used here are planning benchmarks, not engineering or code values. Actual debris can vary substantially with building age, construction method, foundation, material mix, salvage, moisture, compaction and how the debris is loaded.
Methodology & sources
- Building-type generation benchmarks: 111.3 lb/sq ft for single-family residential demolition, 127 lb/sq ft for multifamily residential demolition, and 155 lb/sq ft for nonresidential demolition, as published in a municipal C&D waste-management planning guide.
- Mixed C&D volume conversion: 0.24 tons per cubic yard. Florida DEP reports this as an average bulk density derived from 171 measured C&D loads at 10 facilities.
- U.S. EPA notes that C&D debris includes materials such as steel, wood, drywall, brick, asphalt shingles, concrete and asphalt concrete, and that demolition estimates vary by building and material mix.
