Decide bid or no-bid in minutes, not days.
Constimator reads the plans and specs for you, pulling the numbers that make or break a job — engineer's estimate, project duration, liquidated damages, bonding, and DBE goals — so you know which projects are worth pursuing.
Trusted by public works contractors & estimators
What we extract
The numbers that decide the bid
Constimator scans the plans and specifications and pulls the parameters public works contractors need to make a fast, informed go / no-go call.
Engineer's estimate
See the agency's estimated construction cost up front, so you can gauge project size and whether it fits your book of work.
Project duration
Pull working-day and calendar-day requirements automatically to check them against your crew's availability.
Liquidated damages
Surface the daily penalty for late completion instantly, so schedule risk is priced in before you commit.
Bonding requirements
Identify bid, performance, and payment bond thresholds to confirm the job is within your bonding capacity.
DBE / goal requirements
Extract disadvantaged business enterprise goals and participation requirements before they become a surprise.
Bid details & deadlines
Capture bid due dates, prevailing wage, and submission requirements so nothing critical slips through the cracks.
How it works
From plan set to decision in three steps
Stop reading hundreds of pages just to learn a project isn't worth chasing. Constimator does the first pass for you.
Upload the plans & specs
Pull a project straight from OnlinePlanService.com or drop in the bid documents. Constimator handles the full plan set and specifications.
We extract the key parameters
Engineer's estimate, project duration, liquidated damages, bonding, DBE goals, and bid deadlines are read from the documents and organized into one summary.
Make the bid / no-bid call
Review the summary against your capacity and appetite, then decide with confidence which projects deserve a full estimate.
After you decide to bid
Turn the specs into a full AI takeoff
Once a project is worth chasing, Constimator pulls every bid document from the specs and runs an automated takeoff across all trades — or just the ones you self-perform.
All trades, or the ones you choose
Run a complete takeoff or select only the trades you self-perform. Constimator organizes quantities by trade so scopes stay clean.
Measured straight from the documents
Linear, area, and count quantities are read from the plan set and specifications and marked up sheet by sheet for you to verify.
A confidence score on every trade
Each trade comes back with an estimated accuracy so you know where the AI is strong and where a human set of eyes will pay off before you commit to a number.
