Demolition Estimating & Bidding Software
Demolition estimating is driven by disposal as much as by the work itself. Debris volume, haul distance, and tipping fees frequently exceed the labor to take something apart — and hazardous material assessment can reshape the entire bid. Pro Spec IQ prices removal and disposal separately.
What Pro Spec IQ tracks on a demolition bid
Beyond material, labor, and equipment, demolition bids get inputs specific to the trade:

These are editable defaults, not fixed rates. Set them per bid to match your own cost structure and the risk on the job.
What drives cost on demolition work
- Area or volume to be demolished
- Debris volume and the number of hauls required
- Disposal and tipping fees, which vary by material and facility
- Equipment type and hours
- Hazardous material abatement, where asbestos or lead is present
Where these estimates go wrong
- Underestimating debris volume and the resulting haul count
- Bidding before a hazardous material survey on any older structure
- Missing protection and shoring cost on selective interior demo
- Omitting utility disconnect coordination
Demolition estimating questions
How do you estimate a demolition job?
Determine what's being removed and estimate resulting debris volume, then price hauling and disposal from that. Add equipment hours, labor, protection and shoring, and any abatement, then apply markups. Pro Spec IQ tracks area, debris volume, and disposal as separate inputs.
Why does disposal deserve its own line?
On many demolition jobs, hauling and tipping fees are a larger share of cost than the labor to demolish. Separating them makes the bid easier to adjust when material quantities or facility rates change.
How should hazardous materials be handled in a bid?
Abatement is normally scoped and priced separately after a survey, and excluded from the base demolition bid until the survey is complete. Pro Spec IQ supports scope notes and exclusions on every bid.
