Waterproofing Estimating Softwarefor Washington Contractors

What's actually being bid around DMV
500+ waterproofing contractors chasing work in Washington, growth tracking 9% year-over-year. Average ticket sits around $135,000, labor rates run 25% above the US benchmark, and government work is what most waterproofing contractors are quoting on this week.
Government work
Plan sets we see most: government. Recurring scope items get pre-counted, so you spend the time on the unusual stuff instead of re-counting outlets.
Commercial work
Commercial jobs in DMV tend to share details — once you've priced one, the AI learns your pricing assemblies and applies them to the next.
Historic work
For historic work specifically, the gotcha is usually Underestimating drainage requirements. Flag it at takeoff.

Stuff Washington waterproofing contractors ask before they sign up
Does this respect DC code, or do I have to re-cut every quantity?
DC doesn't license waterproofing 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 below-grade wall area calculations?
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 government work in Washington, 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 Washington bid afterward.
How much does a permit add to a waterproofing job around here?
Plan on $350–$9,000 in Washington, with review running 4–10 weeks. Build that into general conditions so a slow plan-check doesn't eat your overhead. Insurance and bond are separate carrying costs.
