Use cases/Construction and industrial/AI estimating
AI estimating for construction and trades
AI estimating means a first pass estimate produced by a model from your drawings, scope and cost history. An estimator then reviews it. The estimator keeps the job. What goes is the measuring, looking up and retyping that takes most of their week.

Architecture
Everything runs on your servers
We build it on what you already have. Your cost catalogues, your priced jobs, your supplier rates and your templates. The estimator gets a draft that looks like theirs, and every quantity and rate shows where it came from. They spend the day on risk and margin instead of takeoffs.

It takes four jobs off the estimator
- 01
Quantities from drawings and scope
A first pass takeoff against the elements your estimators already use, on consistent drawing sets. Low confidence items are listed first so attention goes where it is needed.
- 02
Pricing from your own history
Rates pulled from the jobs you priced and won, per client type, with the source job shown beside each one. Current supplier and subcontractor pricing where you have it.
- 03
Drafts in your template
The estimate lands in the format the client asked for, whether that is your own template or a head contractor schedule. Reformatting the same scope for every client stops.
- 04
Estimates from a phone
For smaller jobs, a site lead sends a description and photos to WhatsApp and gets a draft estimate back from your cost catalogue for review. No desk required.
It goes live in five steps
- Step 01
Load your cost history
Priced jobs, cost catalogues and supplier rates, structured and attached to the job they came from. Without this step the estimate is generic.
- Step 02
Test against jobs you already priced
Run the draft over past tenders and compare. You learn how often it is wrong, by how much, and on what work. That sets the review threshold and the project type to start with.
- Step 03
Draft from the drawings and scope
Quantities against your elements, rates with the source job beside each one, laid out in the template the client asked for.
- Step 04
Estimator reviews and owns the number
Low confidence items first. Risk, margin and client judgement stay with the person. Nothing leaves without their sign off.
- Step 05
Add the phone route for small jobs
A site lead sends a description and photos to WhatsApp and gets a draft estimate back from the cost catalogue for review.
Software or a custom build
If you are a small builder or trade business doing common work, buy a product first. Buildxact, CostX, Cubit and the trade quoting platforms are adding AI to estimating and they are cheaper than anything custom. A custom build earns its cost in three cases. Your pricing logic is specific to your business. You tender in several client formats. Or the estimate needs cost history and supplier data that the product cannot see.

In practice
A Sydney construction business running Procore had years of tenders and job files sitting as PDFs. We made them machine readable on a private server they rent first, then built estimating on top. A site lead now sends a scope and photos to WhatsApp and gets a draft back from the company cost catalogues for review. A draft that took hours now takes minutes.
Fewer than 30 percent of Australian construction businesses were using AI in early 2026, according to the National AI Centre. An estimating team that does this is still ahead of most of the tenders it competes against.

Questions
Is AI estimating accurate?
As accurate as the history it is built on. Pricing drawn from your own won jobs and current supplier rates is far more reliable than a generic database. Every setup is tested against your past jobs before it goes live so you know its error rate, and the estimator reviews every draft.
What is the best AI for construction estimating?
For a small builder doing common work, a product with AI built in, such as Buildxact or CostX, is the right first step. For a business with its own cost catalogues, several client formats and years of priced jobs, a build on your own data beats any product. It uses your own rates and margins.
Does AI estimating replace the estimator?
No. It replaces the measuring and retyping. The estimator still prices risk, reads the client and owns the number. Businesses that set this up typically price more tenders with the same team rather than fewer people.
How does estimating over WhatsApp work?
A site lead or estimator sends a job description and photos to a WhatsApp number. The system drafts an estimate from your cost catalogue and past pricing in your template and sends it back. A person reviews and sends it to the client. Nothing goes out unreviewed.
