Demolition Estimating Softwarefor Seattle Contractors
If you're bidding demolition in Seattle, the gap between a job that nets margin and one that doesn't usually comes down to underestimating debris volume. Drop a plan set in, walk away for 12 minutes, come back to a priced bid you can defend.
What's actually being bid around Puget Sound
500+ demolition contractors chasing work in Seattle, growth tracking 10% year-over-year. Average ticket sits around $115,000, labor rates run 35% above the US benchmark, and tech work is what most demolition contractors are quoting on this week.
Tech work
Plan sets we see most: tech. Recurring scope items get pre-counted, so you spend the time on the unusual stuff instead of re-counting outlets.
High-Rise work
High-Rise jobs in Puget Sound tend to share details — once you've priced one, the AI learns your pricing assemblies and applies them to the next.
Green Building work
For green building work specifically, the gotcha is usually Missing hazmat survey. Flag it at takeoff.

Stuff Seattle demolition contractors ask before they sign up
Does this respect WA code, or do I have to re-cut every quantity?
WA doesn't license demolition at the state level, so the variability comes from local amendments. Quantities are correct; you adjust crew rates and local permit assumptions in the bid summary.
How do you handle volume calculations for debris?
The model reads the plan once, counts symbols against your assembly library, and surfaces the count for review. You override anything that looks off before it hits the quote. For tech work in Seattle, the typical correction is one or two assemblies — not redoing the whole thing.
What about site conditions?
Build the local condition into your assembly defaults once, and it carries forward to every Seattle bid afterward.
How much does a permit add to a demolition job around here?
Plan on $400–$12,000 in Seattle, with review running 6–14 weeks. Build that into general conditions so a slow plan-check doesn't eat your overhead. Insurance and bond are separate carrying costs.
