AI for builders: the leak is upstream of the build
If you run a residential or commercial building business, the leak isn't on site. It's in the estimate-and-coordinate dance that happens before site.
We've worked with mid-tier builders ranging from $4M to $40M. The pattern is consistent. The job is mostly lost or won before a hammer swings.
The estimate problem
Most builders take 8–14 days to turn around a quote. The good ones turn it around in 36 hours. By day 5, the client has signed someone else.
The fix is an estimate-drafter agent. It reads the BoQ or the architect's plans, pulls comparable jobs from your historical data, and generates a first-pass quote within hours. The estimator's job changes from 'type the quote' to 'review and sign'. Time to quote: 36 hours instead of 11 days. Win rate goes up 20%+ on the strength of pace alone.
The sub-coordination problem
PMs lose half a day a week chasing trades for confirmations, variations, and paperwork. A sub-coordinator agent — sends reminders, chases confirmations, escalates only when needed — gives that half-day back. Compound across 4 PMs in a $20M business and you've recovered 8 days of project management every month.
The reporting problem
What's on the dashboard is two weeks behind what's on site. A daily site-digest agent — reads the foreman's photos and texts, summarises into one paragraph, posts to the PM's Teams channel — closes the gap to one day.
Builders don't lose jobs on site. They lose them in the gap between architect and contract.
What not to build
Don't build an AI 'project manager'. Don't build an AI customer-portal. Don't build anything that asks the foreman to learn new software. The foreman will not learn new software. Build for the office. Leave the site alone.
