Main cost drivers
Scope clarity, excluded work, utilities, permits, debris, insurance, schedule, payment terms, cleanup, and change-order rules determine bid quality.
Compare demolition bids by scope, exclusions, permits, utilities, debris, hazmat, insurance, schedule, cleanup, and contingency.
Comparable bid = same scope + same exclusions + same debris assumptions + same permit and utility responsibilities
Use this mathematical model to prepare budget expectations, then confirm local labor, tipping fees, permits, and utility disconnections prior to contractor signoff.
| Scenario | Planning Range | Project Notes |
|---|---|---|
| Low bid review | Check exclusions first | Low totals often omit permits, hauling, foundation, or hazmat assumptions. |
| Middle bid review | Compare line items | Balanced bids usually show clearer quantities and responsibilities. |
| High bid review | Check risk coverage | Higher bids may include protection, insurance, or contingency missing elsewhere. |
Scope clarity, excluded work, utilities, permits, debris, insurance, schedule, payment terms, cleanup, and change-order rules determine bid quality.
Verify licensing, insurance, permits, utility disconnects, and hazardous material handling before selecting a demolition contractor.
Use this checklist after running the estimator so each contractor is pricing the same assumptions.
Compare included scope, exclusions, permits, utilities, hauling, disposal, cleanup, and change-order terms before comparing totals.
Vague scope, missing permit language, no disposal details, unclear insurance, and no utility plan are common warning signs.
